Finding suitable forage patches in a heterogeneous landscape, where patches change dynamically both spatially and temporally could be challenging to large herbivores, especially if they have no a priori knowledge of the location of the patches. We tested whether...

Mutualistic communities play an important role in biodiversity preservation. They are modeled as bipartite networks and measurements of centrality and degree help to order species and their relative importance for network robustness. Identifying the most endangered...

1. Camera loggers are increasingly used to examine behavioural aspects of free-ranging animals. However, often video loggers are deployed with a focus on specific behavioural traits utilizing small cameras with a limited field of view, poor light performance and...

Geographic variation in external morphology is thought to reflect an interplay between genotype and the environment. Morphological variation has been well-described for a number of cetacean species, including the bottlenose dolphin (Tursiops truncatus). In this...

Many species of birds react to climate change, for example, by wintering in areas closer to their breeding areas. We investigated the responses of two different functional groups of waterbirds to factors associated with climate change. The Odra River Estuary (SW...

Denitrification is an important part of the nitrogen cycle and the key step to removal of nitrogen in surface-flow wetlands. Denitrifying bacteria also function in denitrification. In this study, we explored space-time analysis with high-throughput sequencing to...

Metatranscriptomics and metaproteomics make it possible to measure gene expression in microbial communities. So far these approaches were mostly used to get a general overview of the dominant metabolism and physiologies of community members. Recently, environmental...
