A scale of scavenging

Factors influencing the proportion of scavenging in a vertebrates’ diet. Each of the traits/ factors ranges from low on the left to high on the right. A high value for a given trait can either increase scavenging propensity (+ +) or reduce it (– –), the same is true for a...

Weakening barriers and novel communities expected for North American boreal birds

The Cape May Warbler (Setophaga tigrina), a spruce-budworm specialist that breeds regularly throughout boreal coniferous forests of North America east of the Western Cordillera, is one of 31 species considered likely to expand its range into the Alaskan boreal...

Advantages of being a dark beetle – Insect colouration and thermoregulation

Thermal benefits of dark body colouration (melanism) are known for various groups of ectotherms like amphibians (alpine salamander Salamandra atra, A) and reptiles (melanistic morph of the adder Vipera berus, B).  By studying the body colouration and body...

Trait diversity and environmental variation: sex matters

by Adam C. Algar
 
In this paper, we focused on how phenotypic diversity within a species changes across a diverse set of environments. We were particularly interested in how ‘harsh’...

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)....
