Resumo A raposa-vermelha (Vulpes vulpes) é um carnívoro de médio porte que ocorre em diferentes regiões do Paquistão, porém ainda carece de dados científicos sobre sua ecologia e distribuição. O presente estudo investigou o status filogenético e a dieta da raposa-vermelha (V.v. griffithii) que ocorre no Parque Nacional de Ayubia, Paquistão. Por meio de armadilhas fotográficas e análises moleculares, confirmamos a ocorrência de raposa-vermelha na área de estudo. Com base no citocromo B mitocondrial (304 bp) e amostragem limitada, quase todas as raposas-vermelhas do Parque Nacional de Ayubia e áreas circundantes do Himalaia se enquadram na linhagem materna holártica, enquanto as raposas-vermelhas encontradas nas planícies do Paquistão fazem parte da linhagem materna basal paleártica. Usando 32 fezes, descobrimos que a dieta da raposa-vermelha compreende 80% de espécies de presas de origem animal (selvagens e domésticas) e 19% de matéria vegetal. As espécies de presas de animais selvagens incluíram a lebre-do-cabo (Lepus capensis) e o esquilo-voador (Pteromyini sp.), que constituíram 17% e 15% da dieta, respectivamente. As raposas-vermelhas consumiam raramente ratos domésticos (Mus musculus), algas do Himalaia (Paguma larvata) e ovelhas (Ovis aries), cada um compreendendo cerca de 6% a 9% da dieta da raposa-vermelha. A espécie de raposa também se alimentava de burros domésticos de forma oportunista. Com base em nossa amostragem, nosso estudo sugere que a raposa-vermelha (V.v. griffithii) que ocorre no Parque Nacional de Ayubia e nas cordilheiras menores do Himalaia pertence à linhagem materna holártica. O estudo também destaca o consumo de sementes de plantas por raposas-vermelhas, indicando que pode desempenhar um papel ecológico importante na dispersão de sementes no Parque Nacional de Ayubia.

Abstract The red fox (Vulpes vulpes) is a medium-sized carnivore that occurs in different regions of Pakistan, however, still lacks scientific data on its ecology and distribution. The current study investigated the phylogenetic status and diet of the red fox (V.v. griffithii) occurring in Ayubia National Park, Pakistan. Through camera trapping and molecular analysis, we confirmed the occurrence of red fox in the study area. Based on mitochondrial cytochrome B (304 bp) and limited sampling, nearly all red foxes of Ayubia National Park and surrounding Himalayan ranges fall within Holarctic maternal lineage, whereas red foxes found in plains of Pakistan are part of the basal Palearctic maternal lineage. Using 32 scats, we found that red fox diet comprises of 80% animal-based prey species (both wild and domestic) and 19% plant matter. The wild animal prey species included Cape hare (Lepus capensis) and flying squirrel (Pteromyini sp.), which constituted 17% and 15% of diet, respectively. Red foxes infrequently consumed House mouse (Mus musculus), Himalayan Palm civet (Paguma larvata) and sheep (Ovis aries), each comprising around 6% to 9% of red fox diet. The fox species also scavenged on domestic donkey opportunistically. Based on our sampling, our study suggests that the red fox (V.v. griffithii) that occurs in Ayubia National Park and across the lesser Himalayan ranges belongs to Holarctic maternal lineage. The study also highlights consumption of plant seeds by red foxes, indicating it may play an important ecological role in seed dispersal in Ayubia National Park.

Resumo Os hábitos alimentares de ratos bandicoot (Bandicota bengalensis) foram investigados nas plantações agrícolas do planalto de Pothwar, Paquistão, por meio da análise do conteúdo estomacal. As atividades da pesquisa foram conduzidas nas principais culturas de campo, incluindo trigo e amendoim, e em terras de pousio durante a estação não agrícola nos limites do campo. Os espécimes foram capturados dos campos usando armadilhas kill/snap e dissecados para coletar suas amostras de estômago para análise laboratorial. Lâminas de microscopia de luz do material vegetal foram recuperadas de amostras de estômago; os materiais de referência foram coletados no campo. Os resultados revelaram que o rato bandicoot alimentava-se predominantemente de culturas cultivadas durante a época de cultivo, mas consumia vegetação selvagem durante a época de não colheita. Não houve diferença significativa entre as dietas de verão e inverno. Os alimentos agrícolas mais frequentemente consumidos foram trigo (Triticum aestivum; 28,57%), amendoim (Arachis hypogea; 11,26%), sorgo (Sorghum bicolor; 10,17%), grão de bico (Cicer arietinum; 9,52%), milho (Zea mays; 6,49%), milheto (Pennisetum glaucum; 5,84%), cevada (Hordeum vulgare; 4,98%) e mostarda (Brassica campestris; 4,98%). Entre a vegetação silvestre foram consumidos khbal gha (Cynodon dactylon; 7,79%), barão dhab (Demostachya bipinnata; 7,36%) e flor espinhosa (Achyranthes aspera; 3,03%). O estudo conclui que, além de consumir culturas de trigo e amendoim, o rato bandicoot pequeno também subsiste de gramíneas, ervas daninhas e algumas culturas forrageiras, componentes importantes de sua dieta no agroecossistema do planalto de Pothwar.

Abstract Dietary habits of bandicoot rats (bandicota bengalensis) were investigated in the agricultural crops of the Pothwar Plateau, Pakistan by analysing stomach contents. The research activities were conducted in major field crops including wheat-groundnut and in the fallow lands during non-crop season at the field boundaries. The specimens were captured from the fields using kill/snap traps, and dissected to collect their stomach samples for laboratory analysis. Light microscopic slides of the plant material were recovered from stomach samples and the reference materials were collected from the field. Results revealed that the bandicoot rat predominantly fed upon cultivated crops during cropping season but consumed wild vegetation during non-cropping season. There was no significance difference between summer and winter diets. Most frequently consumed crop food items were wheat (Triticum aestivum; 28.57%), groundnut (Arachis hypogea; 11.26%), sorghum (Sorghum bicolor; 10.17%), chickpea (Cicer arietinum; 9.52%), maize (Zea mays; 6.49%), millet (Pennisetum glaucum; 5.84%), barley (Hordeum vulgare; 4.98%) and mustard (Brassica campestris; 4.98%). Among wild vegetation were consumed khbal gha (Cynodon dactylon; 7.79%), baron dhab (Demostachya bipinnata; 7.36%) and Prickly flower (Achyranthes aspera; 3.03%). The study concludes that, in addition to consuming wheat and groundnut crops, the Lesser bandicoot rat also subsists on grasses, weeds, and some fodder crops, as important component of its diet in agro-ecosystem of the Pothwar Plateau.

Resumo Os roedores podem causar danos significativos às culturas de trigo e amendoim nos países em desenvolvimento, bem como aos produtos armazenados e infraestrutura, afetando a segurança alimentar e a renda dos pequenos agricultores. O trigo (Triticum aestivum) e o amendoim (Arachis hypogea) são culturas comerciais importantes para os agricultores locais no Paquistão. Experimentos de campo foram realizados para avaliar a extensão dos danos de roedores às culturas de trigo e amendoim ao longo de seus estágios de crescimento (ou seja, germinação, floração/formação e maturidade) nas zonas agroecológicas de Pothwar Plateau, Paquistão. Usamos um método de quadrat para registrar o número de plantas de cultura danificadas. Com base nos dados de armadilhagem foram capturadas quatro espécies de roedores de sistemas de cultivo de trigo-amendoim que foram responsáveis por causar danos, ou seja, o rato-bandico-pequeno (Bandicota bengalensis) foi a espécie principal, seguido pelo rato-toupeira-de-cauda-curta (Nesokia indica), o gerbilo-da-índia (Tatera indica) e o rato-do-mato (Golunda ellioti). Em ambas as culturas, o dano máximo foi registrado na maturidade da cultura (10,7 e 14,4%, respectivamente). O menor dano relatado ao trigo e ao amendoim foi no estágio de germinação (3,5% e 6,0%, respectivamente). O menor dano relatado na germinação pode ser devido à disponibilidade de vegetação não cultivada nas bordas do campo, que pode ser um fator potencial que influencia o dano. Nossos resultados mostraram claramente a quantidade considerável de danos causados por roedores ao trigo-amendoim na maturidade em todas as zonas agroecológicas de Pothwar e indicaram que a composição de pequenos mamíferos estava mais relacionada ao estágio de maturidade/estação das culturas quando a disponibilidade de alimentos e as condições climáticas eram favoráveis e com segurança sob abrigo de cultivo. Estudos mais detalhados são necessários para entender completamente a ecologia populacional e reprodutiva das espécies de pragas de roedores relevantes em relação aos padrões de danos para otimizar o manejo, além das medidas estruturais individuais.

Abstract Rodents can cause significant damage to wheat-groundnut crops in developing countries, as well as to stored produce and infrastructure, affecting food security and income of small-holder farmers. Wheat (Triticum aestivum) and groundnuts (Arachis hypogea) are important cash crops for local farmers in Pakistan. Field experiments were performed to assess the extent of rodent damage to wheat-groundnut crops throughout their growth stages (i.e, germination, flowering/peg formation and maturity) in the agro-ecological zones of Pothwar Plateau, Pakistan. We used a quadrat method to record the number of damaged crop plants. On the basis of the trapping data four rodent species were captured from wheat-groundnut cropping systems which were responsible for causing damage, i.e., lesser bandicoot rat (Bandicota bengalensis) was the main species, followed by the short-tailed mole rat (Nesokia indica), the Indian gerbil (Tatera indica) and the bush rat (Golunda ellioti). In both crops, the maximum damage was recorded at crop maturity (10.7 and 14.4%, respectively). The lowest reported damage to wheat and groundnuts was at the germination stage (3.5% and 6.0%, respectively). The lower damage reported at germination could be due to availability of non-crop vegetation at field borders that may be a potential factor influencing damage. Our findings clearly show the considerable amount of damage caused by rodents to wheat-groundnut at maturity across all the agro-ecological zones of Pothwar and indicated that the small mammal composition was more related to maturity stage/season of crops, when the availability of food and climatic condition were favorable and having security under crop shelter. More detailed studies are needed to fully understand the population and breeding ecology of the relevant rodent pest species in relation to damage patterns to optimize management beyond individual structural measures.

Land-based income streams, which include the consumption and selling of crops, livestock and environmental products, are inherent in rural households' livelihoods. However, the off-farm cash income stream - primarily composed of migrant labour remittances, social grants, and savings and loans - is increasing in importance in many regions. This case study of 590 households from Bushbuckridge, South Africa, analyses the economic value of each of these income streams at three points: what enters the household, what is used and what is sold. Two important findings emerge. First, dependence on offfarm cash incomes is far higher than previously suggested by case studies in the area and the benefits of employment accrue to those already better educated and wealthier. This suggests that shifts in offfarm opportunities will exacerbate already deep inequalities. Second, while environmental products and crops are important for direct use, they generate insignificant cash incomes from sales. This suggests a weakening of the direct links between the local ecosystem and this society, challenging traditional notions of African rurality being intrinsically land based. SIGNIFICANCE: Off-farm incomes such as wage labour, remittances and social grants are almost the sole source of cash for households in the study area. Even when including non-monetary incomes such as harvested produce, foraged goods and livestock products, off-farm incomes still represent the overwhelmingly largest proportion of overall household income value. This highlights the fact that South African rural economies are not consistently or primarily land based, and indicates the necessity of rural development strategies that facilitate participation in local cash economies. Otherwise, such efforts will be unable to yield broad benefits and will, instead, simply enrich those who are already better off.
