Abstract The presence of feral fauna in conserved ecosystems causes negative impacts and, combined with pressures to which native flora and fauna are subjected, such as fires, fragmentation, change in land use, have a negative impact on the distribution and density of species, as well as the Loss of species and particularly fauna may be subject to local displacement or extinction processes. The purpose of this study is to identify the species of feral fauna and their habits in a portion of medium-sized jungle located in Acapulco, Guerrero. Eight camera traps were located and georeferenced in a fragment of medium forest with an area of eight hectares from the period March 2022 to January 2023. From the sampling, 1,184 photographs were obtained, two species of feral terrestrial mammals and 5 of native fauna were observed. The most abundant species were Didelphis virginiana (n = 22), Dasypus novemcinctus (n = 12), Canis lupus familiaris (n = 10), Felis silvestris catus (n = 9) and the least abundant were Procyon lotor (n = 3) and Tamandua mexicana (n = 1), with this the feral and native Bambas species have crepuscular nocturnal habits, so if they do not coincide they use the same trails, which increases the possibility of encounters, control activities are required, containment for the feral fauna since the project area borders protected natural areas.

Resumen La presencia de fauna feral en ecosistemas conservados causa impactos negativos y aunado a presiones a las que está sometida la flora y la fauna nativa, tales como incendios, fragmentación, cambio de uso de suelo, repercuten negativamente en la distribución y densidad de las especies, así como la pérdida de las mismas, mientras que la fauna puede ser o estar sujeta a procesos de desplazamiento o extinción de manera local. La finalidad del presente estudio es identificar las especies de fauna feral y sus hábitos en una porción de selva mediana en Acapulco, Guerrero. Se ubicaron y georreferenciaron ocho cámaras trampa, en un fragmento de selva media con una superficie de ocho hectáreas del periodo marzo del 2022 a enero 2023. Del muestreo se obtuvieron 1184 fotografías, en donde se observaron dos especies de mamíferos terrestres ferales y 5 de fauna nativa. Las especies más abundantes fueron Didelphis virginiana (n = 22), Dasypus novemcinctus (n = 12), Canis lupus familiaris (n=10), Felis silvestris catus (n=9) y las poco abundantes fueron Procyon lotor (n = 3) y Tamandua mexicana (n = 1); se evidenció que las especies ferales y nativas ambas tienen hábitos nocturnos crepusculares, por lo que si no coinciden utilizan los mismos senderos, lo que aumenta la posibilidad de encuentros. Por ello, se requieren actividades de control, contención para la fauna feral ya que el área del proyecto colinda con áreas naturales protegidas.

Resumo A presença de fauna silvestre em ecossistemas conservados causa impactos negativos e, aliada às pressões a que estão submetidas a flora e a fauna nativas, como incêndios, fragmentação, mudança no uso do solo, impactam negativamente na distribuição e densidade das espécies, como bem como a sua perda, enquanto a fauna pode estar ou estar sujeita a processos locais de deslocamento ou extinção. O objetivo deste estudo é identificar as espécies da fauna silvestre e seus hábitos em uma porção de selva de médio porte em Acapulco, Guerrero. Oito armadilhas fotográficas foram localizadas e georreferenciadas em um fragmento de floresta média com área de oito hectares no período de março de 2022 a janeiro de 2023. Da amostragem foram obtidas 1.184 fotografias, onde foram encontradas duas espécies de mamíferos terrestres silvestres e 5 de fauna. foram observados. As espécies mais abundantes foram Didelphis virginiana (n = 22), Dasypus novemcinctus (n = 12), Canis lupus familiaris (n = 10), Felis silvestris catus (n = 9) e as menos abundantes foram Procyon lotor (n = 3) e Tamanduá Mexicano (n = 1); Ficou evidente que ambas as espécies silvestres e nativas possuem hábitos noturnos crepusculares, portanto, caso não coincidam, utilizam as mesmas trilhas, o que aumenta a possibilidade de encontros. Portanto, são necessárias atividades de controle e contenção para a fauna selvagem, uma vez que a área do projeto faz fronteira com áreas naturais protegidas.

Abstract Agroecosystems with coffee (Coffea arabica) are biodiversity reservoirs where fauna species can be found, including some mammals. Mammal’s studies in this habitat have been increasing in recent years. It is important to know the richness, abundance, and diversity of species, as well as the periods of activity to understand the dynamic in a productive system such as coffee plantations. The aim is to determine the diversity of mammals in coffee agroecosystems in Rincón de Mora, San Ramón, Alajuela, Costa Rica. To do this, different capture methods were used (Sherman, Havahart type live capture traps, camera traps and mist nets) which were placed in strategic sites for three years of sampling. 22 species of mammals were detected, classified into three groups according to their abundance: higher, medium, and less. The higher presence of mammals occurred in the phenological stages of flowering-filling and fruit-leaf (at the end of the harvest). Data were obtained from mammals during daytime and nighttime hours. The Shannon H diversity index had a result of 1.80, while the Berger-Parker d= 0.69. According to this research, as well as other studies, coffee agroecosystems can be considered an alternative supporting habitat for the protection of mammal species and other associated fauna.

Resumen Los agroecosistemas con café (Coffea arabica) son reservorios de biodiversidad donde se pueden encontrar especies de fauna, entre ellos algunos mamíferos. Los estudios de mamíferos en este hábitat han ido aumentando en los últimos años. Es importante conocer la riqueza, abundancia y diversidad de especies, así como los periodos de actividad para conocer a profundidad la dinámica en un sistema productivo como los cafetales. El objetivo es determinar la diversidad de mamíferos en agroecosistemas con café en Rincón de Mora, San Ramón, Alajuela, Costa Rica. Para ello, se utilizaron diferentes métodos de captura (trampas de captura viva tipo Sherman, Havahart, cámaras trampa y redes de niebla) las cuales se colocaron en sitios estratégicos durante tres años de muestreo. Se detectaron 22 especies de mamíferos clasificadas en tres grupos según su abundancia: mayor, media y menor. La mayor presencia de mamíferos se dio en las etapas fenológicas de floración-llenado y de fruto-hoja (al final de la cosecha). Se obtuvieron datos de mamíferos en horarios diurnos y nocturnos. El índice de diversidad Shannon H tuvo un resultado de 1,80, mientras que el de Berger-Parker d= 0,69. Según esta investigación, así como con otros estudios, se puede considerar que los agroecosistemas con café son un hábitat alternativo de apoyo para la protección de especies de mamíferos y otra fauna asociada.

Resumen Introducción: La dispersión y depredación de semillas tienen efectos importantes en la diversidad de plantas y estructura de las comunidades. Los roedores participan en estos tipos de interacciones. Objetivos: Evaluar la remoción de semillas de Crescentia alata, Randia capitata y Zea mays por la ardilla Notocitellus adocetus, para determinar su efecto en estas especies de plantas, dispersando o depredando semillas. Métodos: Estudiamos 14 individuos de C. alata, 24 para R. capitata y 35 individuos para Z. mays. Observamos el forrajeo y usamos cámaras trampas para determinar la parte del fruto (semilla y/o pulpa) consumida y la intensidad de consumo por las ardillas. También colocamos trampas de arena fina (FST) para medir el porcentaje de remoción de semillas. Cuantificamos los frutos producidos por las especies estudiadas y el porcentaje de daño ocasionado por N. adocetus, mediante parcelas. Resultados: Notocitellus adocetus se alimenta de las semillas y pulpa de C. alata y Z. mays. La especie que tuvo mayor tasa de remoción y mayor porcentaje de daño fue C. alata. La especie con mayor porcentaje de remoción, mayor número de frutos y menor daño en las FST fue Z. mays. En las trampas de arena fina, R. capitata tuvo la menor remoción de semillas. Conclusiones: Notocitellus adocetus es considerada depredadora de semillas, no obstante, por su comportamiento y las características de los frutos de C. alata y R. capitata, este roedor podría dejar disponibles las semillas a dispersores secundarios de semillas.

Abstract Introduction: Seed dispersal and seed predation have important impacts on plant diversity and community structure. Rodents participate in both of these types of interactions. Objectives: To evaluate the removal of the seeds of Crescentia alata, Randia capitata, and Zea mays by the squirrel Notocitellus adocetus to determine how it affects these plant species, by dispersing or preying on their seeds. Methods: We studied 14 individuals for C. alata, 24 for R. capitata, and for Z. mays 35 individuals. We observed foraging and used camera traps to determine the part of the fruit (seed and/or pulp) consumed by the squirrels and the amount of fruit or seed consumed. We also placed fine sand traps (FST) to measure the percentage of seed removal. We quantified the fruits produced by the plant species studied and the percentage of damage caused by N. adocetus throughout the plots. Results: Notocitellus adocetus feeds on the seeds and pulp of C. alata and Z. mays. The species with the highest removal rate and the highest percentage of damage was C. alata. Zea mays was the plant species that had the highest percentage of removal from FST, the largest number of fruits, and the lowest percentage of damage. On FST, R. capitata had the lowest seed remotion. Conclusions: Notocitellus adocetus is considered a seed predator; however, due to its behavior and the characteristics of the fruits of C. alata and R. capitata, this rodent could make the seeds available to secondary seed dispersers.

RESUMO Cleptoparasitas facultativos enfrentam os custos envolvidos no roubo do alimento em troca da compensação pelo valor nutricional do item roubado. Essa interação é pouco conhecida, mas observações anedóticas indicam que aves de rapina podem se beneficiar de sua visão acurada para cleptoparasitar. Reportamos uma tentativa de cleptoparasitismo de um furão-grande, Galictis vittata, por um gavião-branco, Pseudastur albicollis, em uma floresta na Amazônia central brasileira recentemente manejada para corte seletivo de impacto reduzido. Como o furão-grande respondeu agressivamente ao ataque, a tentativa de roubo falhou. O evento foi registrado por uma armadilha fotográfica em uma clareira linear. O ambiente mais aberto pode ter aumentado a habilidade do gavião-branco em encontrar o seu hospedeiro. Eventos de cleptoparasitismo são dificilmente registrados em ambientes florestais. Registros de cleptoparasitismo em florestas tropicais podem não depender apenas do uso intensivo de armadilhas fotográficas, mas também de condições ambientais favoráveis à detecção de possíveis hospedeiros pelo cleptoparasita. roubado conhecida cleptoparasitar furãogrande, furãogrande furão grande, grande vittata gaviãobranco, gaviãobranco gavião branco, branco albicollis reduzido ataque falhou linear hospedeiro florestais fotográficas cleptoparasita

ABSTRACT Facultative kleptoparasites face the risk of trying to steal food resources from competitors. This type of interaction is little known, but anecdotal observations indicate that birds of prey may take advantage of their accurate sight to detect the best opportunities for kleptoparasitism. We recorded a camera trap video of an attempt of kleptoparasitism by the white hawk, Pseudastur albicollis, that tried to steal food from a greater grison, Galictis vittata, in a recently selectively-logged forest site in central Brazilian Amazonia. The attempt was unsuccessful as the greater grison responded aggressively to the attack. The event occurred in a linear clearing, which may have increased the bird’s ability to detect its potential host. Kleptoparasitic interactions are difficult to detect in forest environments. Recording opportunistic kleptoparasitic interactions in tropical forests may not only depend on the increasing use of camera traps, but also on habitat conditions that facilitate the detection of potential hosts. competitors known hawk albicollis vittata selectivelylogged selectively logged Amazonia attack clearing bird s host environments traps hosts

SUMMARY: In this work, we report new records of the Chilean shrew opossum (Rhyncholestes raphanurus), one of the least known mammals of the South American temperate rainforests. Using camera traps, we detected Chilean shrew opossums on 31 different occasions distributed over 17 sites, located in two protected areas of the Los Ríos region, southern Chile. The records, obtained in evergreen and alerce forests, as well as in eucalyptus plantations, show markedly nocturnal activity. These findings represent a significant increase in the number of locations where the presence of this species has been confirmed.

RESUMEN: En este trabajo, presentamos nuevos registros de la comadrejita trompuda (Rhyncholestes raphanurus), uno de los mamíferos más desconocidos de los bosques templados sudamericanos. Por medio de trampas cámaras, detectamos comadrejitas trompudas en 31 ocasiones distribuidas en 17 sitios, ubicados en dos áreas protegidas de la Región de Los Ríos, sur de Chile. Los registros, obtenidos en bosque siempreverde, alerce y plantaciones de eucaliptos, muestran una actividad marcadamente nocturna. Estos hallazgos representan un incremento significativo en el número de localidades con presencia confirmada de esta especie.

ABSTRACT We present the first records of a melanistic jaguar (Panthera onca) coexisting with non-melanistic jaguars in the Cordillera Escalera - Regional Conservation Area, San Martín, Peru. Between the years 2017 and 2022, twelve camera traps were installed in a wildlife corridor to evaluate the occurrence of mammals and birds within the conservation area. A total record of 9 photos and 24 videos was obtained, of which 6 photos and 10 videos corresponded to a melanistic male specimen. The largest number of records was in April and July 2021, during night events. These results represent important evidence of the presence of previously undocumented melanistic jaguars in the area, allowing the strengthening of jaguar conservation initiatives and distribution evaluation within the Cordillera Escalera - RCA.

RESUMO Os mecanismos de segregação ecológica envolvidos na coexistência entre felídeos neotropicais são a chave para subsidiar estratégias para sua conservação. Por apresentarem comportamento inconspícuo e esquivo, as armadilhas fotográficas constituem um método não invasivo estratégico para estudá-los. O presente trabalho buscou avaliar o padrão de atividade diário e sazonal de quatro espécies de felídeos: Leopardus guttulus (Hensel, 1872), L. pardalis (Linnaeus, 1758), L. wiedii (Schinz, 1821) e Puma concolor (Linnaeus, 1771), na RPPN Papagaios-de-Altitude, no estado de Santa Catarina, sul do Brasil. Coletamos os dados através de 25 sítios de armadilhas fotográficas na área de estudo. Obtivemos 624 registros independentes de L. guttulus (108), L. pardalis (55), L. wiedii (77) e P. concolor (384) em um esforço amostral de 12.266 armadilhas/dia. Todas as espécies analisadas apresentaram distribuição de atividade diária não uniforme, quando considerados os dois anos. Relatamos o pico de atividade sazonal de todas as espécies entre os meses de junho a setembro, coincidindo com a safra de pinhão na região, e com o aumento nas populações de pequenos roedores. Também relatamos uma alta sobreposição entre os padrões de atividade das quatro espécies.

ABSTRACT The mechanisms of ecological segregation involved in the coexistence between Neotropical felids are the key to support strategies for conservation. Due to their inconspicuous and elusive behavior, camera trapping constitute a strategic, non-invasive method to study these species. The present work aimed to evaluate the daily and seasonal activity patterns of four felid species: Leopardus guttulus (Hensel, 1872), L. pardalis (Linnaeus, 1758), L. wiedii (Schinz, 1821) and Puma concolor (Linnaeus, 1771), in the Papagaios-de-Altitude Private Protected Area, state of Santa Catarina, southern Brazil. Data were collected from January 2018 to December 2019, using 25 sites of camera traps among the study area. We collected 624 independent records from L. guttulus (108), L. pardalis (55), L. wiedii (77) and P. concolor (384) in a sampling effort of 12,266 camera-traps/day. All species analysed showed a non-uniform distribution of daily activity, when considering the two years. We report the peak of seasonal activity for all species between the months of June and September, coinciding with the Araucaria nut harvest in the study area, and with the increase in populations of small rodents. We also report a high overlap between the activity patterns of the four species. The daily and seasonal activity patterns of the species in this study seem to reflect the intrinsic dynamics of the Araucaria Forest, as well as possible adaptations to prey availability. conservation behavior strategic noninvasive non invasive Hensel, Hensel (Hensel 1872, 1872 , 1872) L Linnaeus, Linnaeus (Linnaeus 1758, 1758 1758) Schinz, Schinz (Schinz 1821 1771, 1771 1771) PapagaiosdeAltitude Papagaios de Altitude Area Catarina Brazil 201 2019 2 area 62 108, 108 (108) 55, 55 (55) 77 (77 P 384 (384 12266 12 266 12,26 cameratraps/day. cameratrapsday traps/day. day camera-traps/day nonuniform uniform years September rodents Forest availability 187 175 182 177 20 6 10 (108 5 (55 7 (7 38 (38 1226 1 26 12,2 cameratraps cameratraps/day trapsday traps/day 18 17 (10 (5 ( 3 (3 122 12, (1

Abstract The Cerrado domain and its biodiversity has suffered several anthropogenic influences. Our objective was to evaluate the influence of biotic and anthropic variables on the mammal community in a protected area in the Cerrado-Caatinga ecotone. For this we sampled the mammals using camera traps (4,072 days/trap) for 16 months. We used generalized mixed linear models (GLMM) with model selection via Akaike’s Information Criteria corrected for small sample size (AICc) to assess the influence of variables on richness, abundance and functional groups of mammals. We made a total of 663 photographic records of 16 species of medium and large mammals. The richness and number of mammals was negatively influenced by the distance to human settlements while carnivores were not affected by any of the variables evaluated, herbivores and generalists were more common in areas closer from human habitation. Despite the presence of large areas of native vegetation, our results show that there is a dominance of common and generalist species. The protected area is vulnerable to different sources of human pressure and the design and implementation of a management plan can be a key tool for protecting biodiversity and regulating the use of natural resources by local communities. influences CerradoCaatinga Caatinga ecotone 4,072 4072 4 072 (4,07 days/trap daystrap days trap 1 months GLMM (GLMM Akaikes Akaike s AICc (AICc 66 evaluated habitation vegetation communities 4,07 407 07 (4,0 6 4,0 40 0 (4, 4, (4 (

Resumen En 2013 una ambigua fotografía de cámara trampa puso en discusión la extinción del aguará guazú en el territorio uruguayo. Este registro, tomado en el marco de un monitoreo participativo con cámaras trampa realizado en Paso Centurión, un área protegida del departamento de Cerro Largo, en el noreste del Uruguay, da lugar a reflexiones antropológicas sobre distintas formas de conocimiento y relaciones entre humanos y animales que se encuentran, dialogan y tensionan. Este trabajo parte de una etnografía sobre diálogos entre conocimientos locales y biológicos, enfocando en particular en un monitoreo participativo con cámaras trampa desarrollado por una organización civil que combina biología y activismo ambiental en la localidad. Nos centramos en las relaciones con uno de los animales registrados, el aguará guazú, para discutir acerca de sus categorizaciones como especie rara, presente o elusiva y su devenir como emblema del monitoreo. 201 uruguayo registro Centurión Largo Uruguay encuentran tensionan biológicos localidad registrados rara 20 2

Abstract In 2013, an ambiguous camera trap photograph called into question the extinction of the maned wolf in Uruguayan territory. This record, taken within the framework of participatory monitoring with camera traps carried out in Paso Centurión, a protected area in the department of Cerro Largo, Uruguay, give rise to anthropological reflections on different forms of knowledge and relationships between humans and animals that meet, dialogue and tense up. This work is based on an ethnography on dialogues between local and biological knowledge, focusing in particular on a participatory monitoring with camera traps developed by a civil organization that combines biology and environmental activism in the locality. We focus on the relationships with one of the recorded animals, the maned wolf, to discuss its categorization as a rare, present or elusive species and its becoming an emblem of monitoring. 2013 territory record Centurión Largo Uruguay meet up locality rare 201 20 2

Abstract Fire might occur under natural conditions in the Pantanal of Brazil; however, with climate change, severe periods of drought potentiated the devasting fires in 2020, resulting in substantial wildlife loss. Considering that mammal communities are strongly affected by fire and habitat alterations, the aim of this study was to evaluate possible differences in mammal diversity and the number of records before and one year after the fire in one region of the Pantanal of Mato Grosso, Brazil (Parque SESC Baía das Pedras - PSBP). The data collection was performed using camera trapping between 2015 and 2017 and 2021, together with visual field observations in PSBP. We observed that the mammal assemblage composition was similar before and one year after the fire. Four species were more or less frequent in burned areas than in unburned ones. Since the fire was controlled in this area, avoiding its total destruction, and the species that fled from the surrounding areas, which were completely burnt, might be using PSBP as a refuge while the vegetation recovers elsewhere. Therefore, the PSBP might have contributed to protecting mammal species after the fire and maintaining and conserving biodiversity on a regional scale in the Pantanal of Mato Grosso, Brazil. however change 2020 loss alterations Grosso Parque .

Abstract The identification of biodiversity conservation priority sectors that are not formally protected, have an essential part of conservation strategies and goals at global and local scale. Ecological niche modeling is a relevant and important tool for analysis and distribution of species, also is used to determine the biodiversity patterns through the regions. The main objective of this work was to identify the sites with high biodiversity patterns in a sector of Chaco Seco ecoregion that haven’t been protected with environmental legislation. Through biodiversity sampling with foot transects, camera traps and interviews, it was registered the presence of large and medium mammals in Santiago del Estero Province. Biodiversity pattern maps were then developed from potential distribution models (SDMs) of 5 mammalian species selected for being relevant for conservation. To define zones that could be characterized like conservation gaps, pattern maps were contrasted with protected areas layers and legal schemes of land use planning and also, protected forest. For the SDM, 171 records were used, 43 for M. gouazoubira, 40 for P. concolor, 20 for M. trydactila, 43 on P. tajacu and 25 on C. wagneri. Three models were used to make the biodiversity patterns, one of these, Fuzzy union, were used for the subsequent calculation. The total area of high biodiversity increases to 39.486 km², which represents the 29% of provincial area. In consequence the 81% remaining represents the conservation gaps areas for that sector of the ecoregion. scale regions havent haven t legislation transects interviews Province SDMs (SDMs forest SDM 17 4 M gouazoubira P concolor 2 trydactila C wagneri these union calculation 39486 39 486 39.48 km² km 29 81 1 3948 3 48 39.4 8 394 39.

RESUMEN El objetivo de este estudio fue comparar la eficacia de trampas Jackson (TJ) convencionales vs. TJ modificadas con una cámara fotográfica (TJCF) en la captura e identificación de machos de Ceratitis capitata en huertos frutales en pleno desierto de Atacama (Pica, Región de Tarapacá). Ambas trampas fueron cebadas con Trimedlure. Entre octubre y diciembre de 2018, se liberaron periódicamente machos estériles de C. capitata, y se contrastaron las magnitudes de capturas en ambos tipos de trampas. La capacidad de las TJCF de proporcionar imágenes a partir de las cuales reconocer los machos capturados también fue evaluada. Los resultados mostraron que las capturas no fueron estadísticamente diferentes en magnitud entre ambos tipos de trampas (p = 0,8901). Hubo en promedio alta concordancia (94%) entre la identificación de C. capitata desde imágenes captadas por la TJCF y la respectiva revisión presencial de los individuos en campo. El algoritmo de conteo automático presentó un error promedio de un 14%. Al evaluar la concordancia entre la temperatura registrada por sensores dispuestos en la TJCF y las mediciones hechas en una estación agrometeorológica cercana al sitio de estudio, se observó un 94% de concordancia entre ambas mediciones. Los resultados indican que el uso de trampas modificadas para vigilancia temprana y remota de C. capitata es técnicamente factible, sin embargo, se debe mejorar el algoritmo de reconocimiento automático para su eventual adopción por el Ministerio de Agricultura a cargo del control oficial de C. capitata en Chile. Se sugiere evaluar su uso en sitios distantes de difícil acceso, puesto que permitiría generar ahorros en recursos humanos y materiales, además de proveer de antecedentes ambientales del sitio de estudio.

ABSTRACT The objective of this study was to compare the efficacy of conventional Jackson traps (JT) vs. modified JT with a photo camera added (TJCF) in the capture and identification of males of Ceratitis capitata in fruit orchards located in the Atacama Desert (Pica, Tarapacá Region). Both traps were baited with trimedlure. From October through December 2018, sterile C. capitata males were periodically released, and catches in the traps were compared. The capability of the TJCF to provide images for the identification of C. capitata was also evaluated. The results showed that male catches were not statistically different between trap types (p = 0.8901). On average, there was a high concordance (94%) between the identification of C. capitata from the images taken by the camera and the on-site assessment. The automatic counting algorithm presented an average error of 14%. When evaluating temperature values recorded by the sensors integrated into the TJCF and those obtained from a weather station nearby, concordance was 94%. Our results suggest that the use of modified traps is technically feasible for remote surveillance of C. capitata, however the algorithm must be improved in order to be eventually adopted by the Chilean Department of Agriculture in charge of C. capitata official control. Further research is required to evaluate their use in remote and difficult to reach areas, since this would allow saving human and material resources as well as collecting environmental data of the study site.

BACKGROUND: Much of the Grassland Biome in South Africa is prone to shrub encroachment, leading to loss of ecosystem services, habitat heterogeneity and species diversity. Burrowing mammals are an important component of grasslands as these animals create microhabitats for other taxa, including smaller mammal species, birds, reptiles and invertebrates. However, our understanding of how shrub encroachment affects burrowing mammals is poor OBJECTIVES: Here we assessed the relationship between burrow abundance and bankrupt bush, Seriphium plumosum, encroachment as well as burrowing mammal diversity in bankrupt bush encroached and non-encroached grasslands METHOD: Shrub density, medium and large mammal burrow abundance and density were measured in 24 encroached and 24 non-encroached areas randomly selected in the Telperion Nature Reserve, Mpumalanga, South Africa. In addition, burrowing mammal diversity was assessed using camera traps in a subset of six encroached and six non-encroached areas RESULTS: Our results show that the abundance and density of medium and large burrows were significantly lower in encroached areas than in non-encroached areas (p = 0.011 and p < 0.001, respectively). The relationship between burrow abundance and bankrupt bush encroachment was negative (rho = -0.456, p = 0.001). However, burrowing mammal diversity had no significant difference between encroached and non-encroached areas CONCLUSION: Our data, therefore, suggest that with increasing bankrupt bush encroachment and a decreased abundance in burrowing mammal ecosystem services, a negative effect will occur on burrowing mammal communities, leading to the reduction in species-specific habitat heterogeneity and possibly animal biodiversity

Resumen Las áreas de conservación privadas (APC) son un recurso complementario para favorecer la conservación de los mamíferos en las regiones tropicales del mundo. Sin embargo, su reducida superficie puede ejercer una influencia diferencial sobre las especies presentes en términos de comportamiento y afectar su coexistencia. Durante la temporada de lluvias de 2016 investigamos los patrones de actividad diaria de los mamíferos del dosel en una APC de 100 ha en una selva. Para ello, se colocaron 11 cámaras trampa en los árboles, a 15 m de altura. Sciurus deppei presentó actividad diurna, Potos flavus alrededor de la medianoche y Caluromys derbianus y Coendou mexicanus antes y después de la medianoche. Tamandua mexicana y Didelphis marsupialis estuvieron activos durante toda la noche. Los mamíferos nocturnos mostraron gran superposición en sus horas de actividad. En general, no hubo diferencias en los patrones de actividad de los mamíferos del dosel en esta APC en comparación con los reportados en áreas naturales protegidas más grandes. El mayor número de registros ocurrió en los árboles más altos ubicados en las partes mejor conservadas del área de estudio, lo que sugiere la importancia de que las APC estén forestadas para la conservación de los mamíferos del dosel.

Abstract Private Conservation Areas (CPAs) are a complementary resource to support mammal conservation in tropical regions of the world. However, their small surface area can exert a differential influence on the species present in terms of behavior and affect their coexistence. During the 2016 rainy season, we investigated the daily activity patterns of canopy mammals in a 100 ha CPA in a rainforest. For this, 11 camera traps were placed in the trees, 15 m high. Sciurus deppei showed diurnal activity, Potos flavus around midnight, and Caluromys derbianus and Coendou mexicanus before and after midnight. Tamandua mexicana and Didelphis marsupialis were active throughout the night. Nocturnal mammals showed great overlap in their hours of activity. Overall, there were no differences in canopy mammal activity patterns in this APC compared to those reported in larger protected natural areas. The greatest number of records occurred in the tallest trees located in the best-preserved parts of the study area, suggesting the importance of APCs being forested for the conservation of canopy mammals.
