ECR feature: Joshua Hallas on the influence of historical biogeography and current environmental variation on patterns of genetic diversity.

Joshua Hallas is a PhD student at the University of Nevada in the USA. He is an evolutionary biologist interested in how environmental variation and natural histories mediate population structure, local adaptation, and genetic differentiation through time. Here, Joshua shares his recent work on the population genetics of the Western terrestrial garter snake. Joshua HallasContinue reading “ECR feature: Joshua Hallas on the influence of historical biogeography and current environmental variation on patterns of genetic diversity.”

Latitudinal gradient of host breadths in herbivorous butterflies

The combination of accumulated occurrence data and host use records across Japan revealed that the fundamental resource specialization of butterfly communities becomes more specialized toward higher latitudes. Above: Japonica lutea is a butterfly species widely distributed in Japan. Photograph by Ryosuke Nakadai. Are host breadths of herbivorous insects more specialized in the tropics compared toContinue reading “Latitudinal gradient of host breadths in herbivorous butterflies”

Award highlight: Connecting the past with the present

A paper describing two centuries of changes in crop regions is awarded the Humboldt-Caldas medal 2021 for best biogeography paper in Colombia/Ecuador. Above: Original cartography of Caldas’ crop regions showing the colonial profile of the travel route with vertical elevations, towns and the different crops Ali Salim. Ever since I began studying plant biology, IContinue reading “Award highlight: Connecting the past with the present”

Time waits for no one, except in cities

‘Change is the only constant in life’ and in the Anthropocene the nature of change is being altered too. Though we often associate human activities with increasing rates, a new study of urbanization shows that in some places we are in effect slowing down time instead. Above: Seasonal dissimilarity of bird community composition in urbanizedContinue reading “Time waits for no one, except in cities”

Pool diversity shapes unique island communities

Compiling a new island dataset enables a global perspective on the unique diversity of the smallest communities. Above: A group of small islands Pianemo, Raja Ampat, Indonesia. Like many before us, we studied island systems to better understand the drivers community composition.  Photo by Sutirta Budiman on Unsplash. Island biogeography is one of the mostContinue reading “Pool diversity shapes unique island communities”

ECR Feature: Isabel Haro-Bilbao & Josh Thia on the use of genomics to identify fisheries stocks

Isabel Haro-Bilbao and Josh Thia met while completing their PhD’s at the University of Queensland, Australia. Both had interests in the ecology of marine organisms, which led them to collaborate on a project investigating genetic differentiation in the wahoo, a large, highly dispersive pelagic fish. Isabel and Josh share how they used population genomic approachesContinue reading “ECR Feature: Isabel Haro-Bilbao & Josh Thia on the use of genomics to identify fisheries stocks”

Are there general principles governing geographical range evolution?

A simple rule that unites geographical range evolution across terrestrial and marine environments. Above: Holacanthus ciliaris (left) is broadly distributed, from the state of Florida (USA) to Santa Catarina (southern Brazil), whereas Hyplopectrus providencialis is endemic to the Caribbean islands of San Andrés and Providencia.
