Cardador, L., and T. M. Blackburn. 2020. A global assessment of human influence on niche shifts and risk predictions of bird invasions B. McGill [ed.],. Global Ecology and Biogeography 29: 1956–1966. 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…

Niche shifts and environmental non-equilibrium in invading alien species undermine niche-based predictions of alien species’ potential distributions and, consequently, their usefulness for invasion risk assessments. Here, we compared the realized climatic niches of four alien amphibian species (Hyla…

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., A. Lira-Noriega, and A. G. Navarro-Sigüenza. 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 18: 19–30. 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…

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.…

Understanding local coexistence and broad‐scale species co‐occurrence patterns are central questions in ecology and macroecology. Niche theory relates both spatial scales by considering the resources (Eltonian niche) and conditions (Grinnellian niche) used by species and allow us to assess the contr…
Menegotto, A., T. F. Rangel, J. Schrader, P. Weigelt, and H. Kreft. 2019. A global test of the subsidized island biogeography hypothesis A. M. C. dos Santos [ed.],. Global Ecology and Biogeography 29: 320–330. 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…

The lack of information about species distribution, also known as Wallacean shortfall, targets most species, even charismatic animals like felids, limiting the performance of scientific study and conservation planning. The knowledge about species distribution (specifically occurrence data) is also a…

Dengue fever is a mosquito-borne disease that has undergone a marked rise in incidence since the 1950s, throughout the world’s tropical regions. Here, we present a hypothesis that this rise in incidence may have been exacerbated by the invasion of house geckos, due to their role in the mosquito vect…

Biodiversity loss due to habitat degradation, exploitation of natural deposits, rapid change of environment and climate, and various anthropogenic phenomenon throughout the last few decades in the quest of development have led to rise in safeguarding species ecological domain. With natural habitat o…
