Microbial biogeography of permafrost thaw ponds

editor
15 July 2016
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...

Range size evolution in gymnophthalmid lizards

editor
17 June 2016

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

editor
15 June 2016

 

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

editor
13 June 2016

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

editor
10 June 2016
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

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

editor
26 February 2016

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

editor
10 February 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...

Towards an integrated theory of Biogeography

editor
8 January 2016

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...

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

editor
28 October 2015

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...
