First JBI Global Colloquium: “Towards a comprehensive understanding of biodiversity-geodiversity relationships”

Geodiversity – the abiotic diversity of the Earth’s atmosphere, surface, and sub-surface, comprising geology, soils, hydrology, climate, landforms, and their interaction – is increasingly recognised as a crucial component of the natural world, and a key element of the “conserving nature’s stage” approach to conservation. Interest in the relationships between biodiversity and geodiversity has grownContinue reading “First JBI Global Colloquium: “Towards a comprehensive understanding of biodiversity-geodiversity relationships””

ECR feature: Jorge Cruz Nicolás on proxies for genetic diversity

Jorge Cruz Nicolás is an evolutionary ecologist, currently working towards his PhD at the Instituto de Ecología, UNAM. He uses genetic tools to study population genetic processes in tree species. Jorge shares his recent work on identifying proxies for genetic diversity based on expectations of the niche centrality hypothesis. Jorge Cruz sampling in a forestContinue reading “ECR feature: Jorge Cruz Nicolás on proxies for genetic diversity”

Miocene diversification of mountain loaches

How ancient river systems, geological barriers and climatic changes in the Western Ghats influenced speciation of balitorid loaches Of the many endemic and evolutionarily distinct freshwater fish lineages of the Western Ghats Biodiversity Hotspot, the mountain loach genus Bhavania comprises a biogeographically fascinating group. Its morphological similarities to the sucker-loaches of Indo-China and Sunda IslandsContinue reading “Miocene diversification of mountain loaches”

ECR Feature: Maria Sporbert on relating local abundance to broad-scale distributions

Maria has just recently submitted her PhD thesis at Martin-Luther-University Halle-Wittenberg. She is a vascular plant ecologist with an interest in macroecolgoical patterns and processes. Maria shares her recent work of highly debated theories on the relationship between species local abundances and their broad-scale distributions. Maria Sporbert.

Recovering palaeo-distributions from rock art

Corroborating, refining, or refuting species’ modelled historical distributions can require innovation in datatypes and the synthesis of diverse kinds of information from sometimes unexpected sources. Ecological niche and species distribution models are tools currently applied in several fields of biology and other disciplines. These models use algorithms to correlate species presence data with environmental layersContinue reading “Recovering palaeo-distributions from rock art”

Satellite images to understand the diversity of minute insects

We use landscape data to understand spatial patterns of diversity of one of the smallest groups of insects: thrips. The study was performed in Reunion island, a small volcanic island of the Indian Ocean. The dramatic changes in elevation, abiotic conditions and anthropisation allowed us to explore multiple variables affecting diversity revealing why, despite moreContinue reading “Satellite images to understand the diversity of minute insects”

ECR Feature: Kathryn (Katie) M. Everson on the diversification of Madagascar’s small montane mammals and reptiles

Katie is a postdoc at the University of Kentucky. She combines phylogenetics and phylogeography to understand species diversity and distributions. Katie shares her recent work on patterns of co-distributed genetic structure among 25 small-bodied animals (tenrecs, rodents, and reptiles) from Madagascar’s highland regions. Name. Kathryn (Katie) M. Everson Personal website. http://www.kmeverson.org Institute. University of Kentucky,Continue reading “ECR Feature: Kathryn (Katie) M. Everson on the diversification of Madagascar’s small montane mammals and reptiles”

Dimensions of amphibian alpha diversity in the New World

Local biological diversity, also known as alpha diversity, has three different components: the number of species in a given area (taxonomic diversity), the number of distinct traits that these species have (functional diversity) and their evolutionary distinctiveness (phylogenetic diversity). The relationships among these components of diversity vary across geography reflecting the differences in eco-evolutionary processesContinue reading “Dimensions of amphibian alpha diversity in the New World”

JBI Annual Report on Equity, Diversity, and Inclusion

An increased awareness of systemic bias in institutions requires that we all examine the practices in which we participate. Around the turn of 2020, the Journal of Biogeography (JBI) began considering initiatives to promote opportunities for researchers currently underrepresented in biogeography, a discussion that continued throughout the year, and will go on for some timeContinue reading “JBI Annual Report on Equity, Diversity, and Inclusion”
