Climate and environment shape jackal diet

Dietary flexibility promotes range expansion: The case of golden jackals in Eurasia. Above: Golden jackal in carcass cleaning role (with raven Corvus corax). According to the literature, the consumption of wild ungulates and domestic animals are mainly due to scavenging. Photo: Zoltán Horváth. Global changes can lead to the expansion of a species geographical range.Continue reading “Climate and environment shape jackal diet”

Although GPS coordinates wereContinue reading “ECR feature: Pieter Sanczuk on plant range shifts under climate change.”

Historical biogeography in recent evolving Neotropical mammals

Oligoryzomys is an intriguing genus of sigmodontines that is distributed in almost all ecoregions of South America and continental Middle America. How did it get to be so diverse and distributed so broadly? Above: A Patagonian specimen of Oligoryzomys longicaudatus, a species representative of one the fastest and geographically wide radiation of Neotropical mammals (photoContinue reading “Historical biogeography in recent evolving Neotropical mammals”

ECR Feature: Paulina Meller on factors shaping diversity in geoxyles

Paulina Meller is finishing her PhD at the University of Hamburg, Germany. She studies the evolutionary forces that generate diversity in plants. Paulina shares her recent work on the environmental factors that have given rise to diversity in geoxyles, plants with disproportionately high below-ground woody biomass. Paulina Meller taking a break from digging in theContinue reading “ECR Feature: Paulina Meller on factors shaping diversity in geoxyles”

Pseudocongruent phylogeographic patterns in forest-living herpetofauna

Similar phylogeographic patterns do not necessarily imply similar evolutionary histories. Instead, environmental factors like the formation of rivers, ancient climatic cycles and climatic gradients could collectively interact with the unique life histories species to strengthen dispersal barriers at different times and generate complex biogeographic patterns. Above: Isolated forest fragment in the Eastern Cape Province ofContinue reading “Pseudocongruent phylogeographic patterns in forest-living herpetofauna”

Colonization across oceanic islands, and how to estimate it

Colonization across oceanic islands is a central topic in island biogeography. PAICE, a new methodological tool to estimate colonization events using floristics, genetics, and accounting for sample size. PAICE is designed to perform comparisons among organisms and archipelagos, and can be used to test explicit biogeographic hypotheses such as the difference in colonization success betweenContinue reading “Colonization across oceanic islands, and how to estimate it”

ECR Feature: Rowan Schley on the diversification of pantropical trees

Rowan J. Schley is a postdoc at the University of Exeter and the University of Edinburgh. He is particularly interested in using genomic approaches to study diversity in tropical ecosystems. Rowan shares his recent work on the diversification of the pantropical tree genus, Pterocarpus, and the relative roles of biome-switching and long-distance dispersal. Rowan withContinue reading “ECR Feature: Rowan Schley on the diversification of pantropical trees”
