Abstract Climate change (CC) and human footprint (HF) shape species spatial patterns and may affect the effectiveness of Protected Areas (PAs) network. Spatial patterns of threatened bird species of Subtropical–temperate hotspots in Southeastern South American grasslands are relevant biodiversity features to guide conservation policies. However, the PAs network covers less than 1% of grassland areas and does not overlap areas with the most suitable environmental conditions for threatened birds. Our aim was to find the most environmentally suitable areas for both current and future threatened birds (2050 and 2070) in Entre Ríos. We applied Systematic Conservation Planning protocols with Ecological Niche Models (ENMs) and ZONATION using distribution interaction function and HF as a cost. Then we overlapped binary maps to find priority areas among time periods. HF showed a more fragmented spatial configuration. The PAs network may include environmentally suitable conditions for threatened birds in CC scenarios and HF. We found areas that showed more connectivity in landscape prioritization over time and ensure high-quality environmental conditions for birds. We concluded that the effectiveness of the PAs network could be improved by overlapping priority areas. Our approach provides a knowledge base as a contribution to conservation-related decisions by considering HF and CC.

We analyze the state of knowledge concerning bats from La Capital Department, Santa Fe Province, Argentina. We update the distribution of Eumops glaucinus, E. patagonicus, E. perotis, Molossus molossus, M. rufus, and Tadarida brasiliensis (Molossidae), and Dasypterus ega, Eptesicus furinalis, and Lasiurus blossevillii (Vespertilionidae) based on the analysis of 128 specimens and literature records. We add 5 new localities, as well as information related to morphology and natural history. Eumops glaucinus is reported for the mammal fauna of Santa Fe Province for the first time. Previous studies on bats in the province have been scarce; increased sampling is needed to fill gaps and achieve a more accurate knowledge about species diversity and distribution patterns.

En el presente trabajo se analiza el estado del conocimiento sobre los murciélagos del departamento La Capital, provincia de Santa Fe, Argentina. Se actualiza mediante el análisis de 128 ejemplares y registros de la literatura la distribución de Eumops glaucinus, E. patagonicus, E. perotis, Molossus molossus, M. rufus y Tadarida brasiliensis (Molossidae), y Dasypterus ega, Eptesicus furinalis y Lasiurus blossevillii (Vespertilionidae). Se agregan 5 nuevas localidades de distribución de las especies, como también datos morfológicos y de historia natural. Se incorpora E. glaucinus a la mastofauna de la provincia. Los estudios previos sobre murciélagos en Santa Fe han sido escasos, siendo necesario incrementar muestreos que permitan cubrir vacíos de información para alcanzar mayor precisión en el conocimiento sobre la diversidad y los patrones de distribución de las especies de la provincia.
