Anthropogenic or Natural Dispersal: Case of the Spiny-Tailed Iguanas (<i>Ctenosaura</i>) on Clarion Island, Mexico. [PDF]
Species can colonize oceanic islands by both natural and human‐assisted dispersal and human‐caused species introductions have had catastrophic effects on ecosystems around the world. The Spiny‐tailed Iguanas inhabiting Clarion Island were previously considered introduced. Molecular data and analyses support iguanas' arrival on Clarion Island by natural

Soils, scale, or elites? Biological innovation in Uruguayan cattle farming, 1880–1913
Abstract This article examines the economics of innovation in livestock rearing during the first globalisation in Uruguay, the country with the most cattle per person in the world, both then and now. Using a new historical dataset of Uruguayan agriculture, the first one at a sub‐provincial level, I exploit regional differences in the adoption of cattle

Abstract The recurrent colonization of freshwater habitats and subsequent loss of diadromy is a major ecological transition that has been reported in many ancestrally diadromous fishes. Such residency is often accompanied by a loss of tolerance to seawater.

This article accounts for species absences before occupancy analyses, addressing a long‐standing concern of whether absence is true or due to low sampling effort. The authors affiliate long‐term bird species trends with functional traits in a lowland tropical rainforest landscape in southeast Mexico to help guide land management and conservation ...

Biogeographic patterns of variation in reproductive success in an invasive weed with allopatric distribution. Abstract Invasive species have the ability to rapidly adapt in the new regions where they are introduced. Classic evolutionary theory predicts that the accumulation of genetic differences over time in allopatric isolation may lead to ...

Tropical Land-Use Change Disrupts Zeta-Diversity Across Taxa. [PDF]
We studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.
