A key assumption in species distribution modeling (SDM) with presence‐background (PB) methods is that sampling of occurrence localities is unbiased and that any sampling bias is proportional to the background distribution of environmental covariates. This assumption is rarely met when SDM practition…

Schnase, J. L., Carroll, M. L., Gill, R. L., Tamkin, G. S., Li, J., Strong, S. L., … Spradlin, C. S. (2021). Toward a Monte Carlo approach to selecting climate variables in MaxEnt. PLOS ONE, 16(3), e0237208. doi:10.1371/journal.pone.0237208 https://doi.org/10.1371/journal.pone.0237208

MaxEnt is an important aid in understanding the influence of climate change on species distributions. There is growing interest in using IPCC-class global climate model outputs as environmental predictors in this work. These models provide realistic, global representations of the climate system, pro…

Destro, G. F. G., Andrade, A. F. A. de, Fernandes, V. de, Terribile, L. C., & De Marco, P. (2020). Climate suitability as indicative of invasion potential for the most seized bird species in Brazil. Journal for Nature Conservation, 58, 125890. doi:10.1016/j.jnc.2020.125890 https://doi.org/10.1016/j.jnc.2020.125890

Wildlife trade is considered one of the most significant pathways for the spread of exotic species, as it is present worldwide and crosses abiotic and biotic barriers. In this sense, identifying potential invaders before they are introduced and analyzing the ecological implications of possible escap…

Análisis del conocimiento histórico de la distribución geográfica y ecológica del loro frente blanca, Amazona albifrons, con evidencia de colonización reciente. Revista Mexicana de Biodiversidad, 91(0), 912708. doi:10.22201/ib.20078706e.2020.91.2708 https://doi.org/10.22201/IB.20078706E.2020.91.2708

La distribución del loro frente blanca, Amazona albifrons, en México incluye la vertiente del Pacífico y del golfo, desde Sonora y el sur de Veracruz, respectivamente, y continúa hasta Costa Rica. Recientemente, se ha registrado más allá de su área de distribución histórica conocida, aparentemente p…

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…

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.…

Tropical Conservation Science, 12, 194008291987882. doi:10.1177/1940082919878827 https://doi.org/10.1177/1940082919878827

Assessing landscape connectivity allows us to identify critical areas that impede or facilitate the movement of organisms and their genes and to plan their conservation and management. In this article, we assessed landscape connectivity and ecological condition of the habitat patches of a highly bio…

Saupe, E. E., Farnsworth, A., Lunt, D. J., Sagoo, N., Pham, K. V., & Field, D. J. (2019). Climatic shifts drove major contractions in avian latitudinal distributions throughout the Cenozoic. Proceedings of the National Academy of Sciences, 116(26), 12895–12900. doi:10.1073/pnas.1903866116 https://doi.org/10.1073/pnas.1903866116

Many higher level avian clades are restricted to Earth’s lower latitudes, leading to historical biogeographic reconstructions favoring a Gondwanan origin of crown birds and numerous deep subclades. However, several such “tropical-restricted” clades (TRCs) are represented by stem-lineage fossils well…
