Climate change and the lasting legacy of old vegetation plots

Figure 1. The eastern flank of Mont St-Joseph, in Parc national du Mont Mégantic, Québec. This photo was taken in spring, while deciduous trees (mostly sugar maple) were just leafing out (light green at low elevation). The dark green at high elevation is boreal forest,...

Herbivore damage increases avian and ant predation of caterpillars on trees along a complete elevational forest gradient in Papua New Guinea

Figure 1. Mt Wilhelm (4509 m a.s.l.; the highest peak of Papua New Guinea) hosts one the most complete and largely undisturbed forest elevational gradient in tropics. Here I took photograph of the upper part of the gradient, from 2000 m to the summit of Mt Wilhelm with its...

Zoochory is a fundamental plant-animal interaction but, today, habitat fragmentation is decreasing gene flow...

Living on the drifting sea ice: polar bears walk on a food conveyor belt

Increasing temperature may compensate for lower amounts of dead wood in driving richness of saproxylic beetles

Dicerca berolinensis favors sun exposed dead wood of European beech.

By Joerg Muller

Saproxylic insects are strongly influenced by temperature but also require specific dead wood features, and thus interaction between the two factors is likely....
