Williamson, J. L., & Witt, C. C. (2021). Elevational niche-shift migration: Why the degree of elevational change matters for the ecology, evolution, and physiology of migratory birds. Ornithology, 138(2). doi:10.1093/ornithology/ukaa087 https://doi.org/10.1093/ornithology/ukaa087

Elevational migration can be defined as roundtrip seasonal movement that involves upward and downward shifts in elevation. These shifts incur physiological challenges that are proportional to the degree of elevational change. Larger shifts in elevation correspond to larger shifts in partial pressure…

Ramírez‐Albores, J. E., Prieto‐Torres, D. A., Gordillo‐Martínez, A., Sánchez‐Ramos, L. E., & Navarro‐Sigüenza, A. G. (2020). Insights for protection of high species richness areas for the conservation of Mesoamerican endemic birds. Diversity and Distributions. doi:10.1111/ddi.13153 https://doi.org/10.1111/ddi.13153

Aim: To assess the representativeness values of Mesoamerican endemic birds within the current network of protected areas (PAs) to determine high‐priority and complementary conservation areas to maximize the long‐term protection of species. Location: From central Mexico to southern Panama. Methods:…

Medina-Fitoria, A., Ávila-Palma, H. D., Martínez, M., Ordoñez-Mazier, D. I., & Turcios-Casco, M. A. (2020). Los murciélagos (Chiroptera) del Caribe de Honduras y Nicaragua: una comparación sobre su diversidad en cinco diferentes coberturas vegetales. Neotropical Biodiversity, 6(1), 147–161. doi:10.1080/23766808.2020.1804748 https://doi.org/10.1080/23766808.2020.1804748

Estudiamos la diversidad de murciélagos en cinco diferentes coberturas vegetales del Caribe hondureño y nicaragüense: bosque maduro (BM), bosque secundario (BS), bosque ripario (BR), tacotales o guamiles (TG) y áreas abiertas (HA); determinando aspectos ecológicos y de conservación para todo el pais…

Cardador, L., & Blackburn, T. M. (2020). A global assessment of human influence on niche shifts and risk predictions of bird invasions. Global Ecology and Biogeography. doi:10.1111/geb.13166 https://doi.org/10.1111/geb.13166

Aim: Estimating the strength of niche conservatism is key for predictions of invasion risk. Most studies consider only the climatic niche, but other factors, such as human disturbance, also shape niches. Whether occupation of human habitats in the alien range depends on the native tolerances of spec…

Rotenberry, J. T., & Balasubramaniam, P. (2020). Connecting species’ geographical distributions to environmental variables: range maps versus observed points of occurrence. Ecography. doi:10.1111/ecog.04871 https://doi.org/10.1111/ecog.04871

Connecting the geographical occurrence of a species with underlying environmental variables is fundamental for many analyses of life history evolution and for modeling species distributions for both basic and practical ends. However, raw distributional information comes principally in two forms: poi…

Prieto-Torres, D. A., Lira-Noriega, A., & Navarro-Sigüenza, A. G. (2020). Climate change promotes species loss and uneven modification of richness patterns in the avifauna associated to Neotropical seasonally dry forests. Perspectives in Ecology and Conservation. doi:10.1016/j.pecon.2020.01.002 https://doi.org/10.1016/j.pecon.2020.01.002

We assessed the effects of global climate change as a driver of spatio-temporal biodiversity patterns in bird assemblages associated to Neotropical seasonally dry forests (NSDF). For this, we estimated the geographic distribution of 719 bird species under current and future climate (2050 and 2070) p…

Zink, R. M., Botero-Cañola, S., Martinez, H., & Herzberg, K. M. (2020). Niche modeling reveals life history shifts in birds at La Brea over the last twenty millennia. PLOS ONE, 15(1), e0227361. doi:10.1371/journal.pone.0227361 https://doi.org/10.1371/journal.pone.0227361

A species presence at a particular site can change over time, resulting in temporally dynamic species pools. Ecological niche models provide estimates of species presence at different time intervals. The avifauna of La Brea includes approximately 120 species dating to approximately 15,000 years ago.…

Menegotto, A., Rangel, T. F., Schrader, J., Weigelt, P., & Kreft, H. (2019). A global test of the subsidized island biogeography hypothesis. Global Ecology and Biogeography. doi:10.1111/geb.13032 https://doi.org/10.1111/geb.13032

Aim: The decreasing capacity of area to predict species richness on small islands (the small‐island effect; SIE) seems to be one of the few exceptions of the species–area relationship. While most studies have focused on how to detect the SIE, the underlying ecological factors determining this patter…
