Microbial biogeography of permafrost thaw ponds

Permafrost thaw ponds are increasing in size and numbers in northern Quebec landscape (Sheldrake River valley; 56°36.66′N, 76°12.93′W). The extent and stage of thawing of the surrounding permafrost determine the spatial distribution as well as the main limnological...

Nordic Society Oikos (NSO), with members in all Nordic countries, now unveils its new logo. NSO is the owner of the internationally distinguished journals Ecography, Journal of Avian Biology, Nordic Journal of Botany and Oikos. NSO is a non-profit organisation, and any...

Range size evolution in gymnophthalmid lizards

By Agus Camacho 

Changes of just a few centimeters in the length of a limb, or of some grams in body weight, may correlate with changes in geographic range size of thousands of square kilometers. These striking relationships may have the key to understand why some...

Universal, easy access to geotemporal information: FetchClimate


 

By Matthew Smith

We dreamed up FetchClimate in around 2010 after years of painful experience by ourselves and our colleagues. Many Ecography readers will know the experience: you just need a bit of environmental information to go along with your research...

Putting insects on the map: near global variation in moth richness

by Liliana Ballesteros-Mejia‎ 

Despite their vast diversity and vital ecological role, insects are notoriously underrepresented in biogeography and conservation, and key broad-scale ecological hypotheses about them remain untested – largely due to generally incomplete...

Temperature tolerance at multiple scales

A chameleon grasshopper (Kosicuscola tristis) and alpine skink (Pseudemoia sp.), share a spot in the sun. As ectotherms, their body temperature is directly linked to environmental conditions, making them good candidates for studies on thermal tolerance....

Parasites in ecosystems: a call for appreciation of their non-trivial role in ecosystem biomass and energetics

Lake Hayes, New Zealand, South Island. One of the four lakes sampled during our study. Picture inserted show an amphipod host, Paracalliope fluviatilis, infected by the trematode parasite, Coitocaecum parvum. Note the proportionally large size of the...

How to combine species distribution models based on different descriptors of the environment

Specimens of Triturus pygmaeus, an endemic amphibian to the Iberian Peninsula, and environment in “San Pablo de Buceite” in 2011, Cádiz (Spain). Favourability model for T. pygmaeus in mainland Spain. Favourability ranges from 0 (white) to 1 (black)....

ORCiD now mandatory for submitting authors

From March 2016, it is mandatory for the submitting author to provide an Open Researcher and Contributor ID (ORCiD) via our ScholarOne system. Co-authors and reviewers are strongly encouraged to also connect their ScholarOne accounts to ORCiD, but it is...

A difficult and new path into the future for North American trees? At least there's no ice in the way this time

By David Roberts

Many scientists have taken to looking back in time to learn about species adaptations to the future. And while not a perfect analogue for future changes, the past can offer lessons in species adaptive or migratory capacities. In this study, we sought...

Species On The Move, Tasmania 2016

The global redistribution of our planets’ species is widely recognised as a fingerprint of climate change, however, the mechanisms that underpin such range shifts are poorly understood. Additionally, the pervasiveness of range shifts, from poles to the equator, and depths of...

Salmon have enormous impacts on the ecosystems they inhabit, particularly riverine systems...

Towards an integrated theory of Biogeography

By Kevin Cazelles, Nicolas Mouquet, David Mouillot and Dominique Gravel

Debates are going on the extent to which ecological interactions spread over spatial scales. The absence of a clear answer to this particular problem casts doubts on the very popular Species...

Abiotic and biotic constraints across reptile and amphibian ranges

EDITOR'S CHOICE JANUARY

By Heather R. Cunningham

 

Does the relative strength of the abiotic and biotic factors limiting species distributions differ at poleward and equatorward boundaries?

 

It is well-known that...

Functional structure and specialization in three tropical plant–hummingbird interaction networks across an elevational gradient in Costa Rica

 

 By María Alejandra Maglianesi 

A primary aim of community ecology is to identify the processes that govern multispecies assemblages across environmental gradients. Ecological networks comprising interacting species of plants and pollinators are particularly...

When does competition matter at the large scales studied by biogeographers?

Editor's choice article for November 2015

By William Godsoe

Competition occurs when different living things harm one another. It is common in nature. As one example, the grass in my lawn becomes less dense when weeds run amok. But it isn’t clear...
