Urban-Wild Interface Diversity: A Comprehensive Checklist of Herpetofauna of Guayaquil, Ecuador. [PDF]

Ecol Evol
Amphibians and reptiles in Guayaquil comprise multiple taxonomic orders and occur across conservation areas, forest remnants, and urban parks, including several endemic species and numerous taxa with type localities in the city. Although most species are globally classified as Least Concern, discrepancies between global and national threat assessments ...

Anthropogenic or Natural Dispersal: Case of the Spiny-Tailed Iguanas (<i>Ctenosaura</i>) on Clarion Island, Mexico. [PDF]

Ecol Evol
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

Preventing extinction in an age of species migration and planetary change. [PDF]

Conserv Biol
Abstract International and national conservation policies almost exclusively focus on conserving species in their historic native ranges, thus excluding species that have been introduced by people and some of those that have extended their ranges on their own accord.

Examining the structure of plant-lemur interactions in the face of imperfect knowledge. [PDF]

Conserv Biol
Abstract Biotic interactions, such as plant–animal seed dispersal mutualisms, are essential for ecosystem function. Such interactions are threatened by the possible extinction of the animal partners. Using a data set that includes plant–lemur interactions across Madagascar, we studied the current state of knowledge of these interactions and their ...

Preliminary insights of the genetic diversity and invasion pathways of Cedrela odorata in the Galapagos Islands, Ecuador. [PDF]

Ecol Evol
Cedrela odorata is the second most invasive tree species in the Galapagos Islands. Using nine microsatellite markers, we found that the genetic diversity of C. odorata in Galapagos is lower (He = 0.55) than in mainland Ecuador (He = 0.81). Our preliminary findings suggest multiple introduction events and that the origin of C. odorata in Galapagos could

Validación de un sistema de evaluación de riesgo de invasión: el sistema Australiano y su potencial uso en especies de plantas introducidas en Chile

Gayana - Botanica, 2022
La evaluación del estatus de especies introducidas ya establecidas en el país es crucial para evitar nuevas invasiones. En este estudio validamos una versión modificada del Australian Weed Risk Assessment (AWRA) para aplicar en Chile.
