Data from: EDAPHOLOG monitoring system: automatic, real-time detection of soil microarthropods

Miklós Dombos, Oxána Bánszegi, Katalin Szlávecz & Andrés Kosztolányi
Soil microarthropods as organic matter decomposers play an important role in soil functioning thus providing ecosystem services. However, ecosystem scale investigations on their abundance and dynamics are scarce because their high spatio-temporal heterogeneity requires huge sample size. Processing and identifying large number of individuals are extremely labour-intensive. We prototyped a device called EDAPHOLOG monitoring system that consists of (1) a probe that catches and detects microarthropods and estimates their body size; (2) a data logger...

Data from: Light enough to travel or wise enough to stay? Brain size evolution and migratory behaviour in birds

Orsolya Vincze
Brain size relative to body size is smaller in migratory than in non-migratory birds. Two mutually non-exclusive hypotheses had been proposed to explain this association. On the one hand, the ‘energetic trade-off hypothesis’ claims that migratory species were selected to have smaller brains because of the interplay between neural tissue volume and migratory flight. In contrast, the ‘behavioural flexibility hypothesis’ argues that resident species are selected to have higher cognitive capacities, and therefore larger brains,...

Data from: Large-brained birds suffer less oxidative damage

Large brains (relative to body size) might confer fitness benefits to animals. Although the putative costs of well-developed brains can constrain the majority of species to modest brain sizes, these costs are still poorly understood. Given that the neural tissue is energetically expensive and demands antioxidants, one potential cost of developing and maintaining large brains is increased oxidative stress (‘oxidation exposure’ hypothesis). Alternatively, because large-brained species exhibit slow-paced life histories, they are expected to invest...

Data from: Towards a common methodology for developing logistic tree mortality models based on ring-width data

Maxime Cailleret, Christof Bigler, Harald Bugmann, J. Julio Camarero, Katarina Cufar, Hendrik Davi, Ilona Mészáros, Francesco Minunno, Mikko Peltoniemi, Elisabeth Robert, María-Laura Suarez, Roberto Tognetti & Jordi Martinez-Vilalta
Tree mortality is a key process shaping forest dynamics. Thus, there is a growing need for indicators of the likelihood of tree death. During the last decades, an increasing number of tree-ring based studies have aimed to derive growth–mortality functions, mostly using logistic models. The results of these studies, however, are difficult to compare and synthesize due to the diversity of approaches used for the sampling strategy (number and characteristics of alive and death observations),...

Data from: Environmental selection is a main driver of divergence in house sparrows (Passer domesticus) in Romania and Bulgaria

Julia C. Geue, Csongor I. Vágási, Mona Schweizer, Péter L. Pap & Henri A. Thomassen
Both neutral and adaptive evolutionary processes can cause population divergence, but their relative contributions remain unclear. We investigated the roles of these processes in population divergence in house sparrows (Passer domesticus) from Romania and Bulgaria, regions characterized by high landscape heterogeneity compared to Western Europe. We asked whether morphological divergence, complemented with genetic data in this human commensal species, was best explained by environmental variation, geographic distance, or landscape resistance—the effort it takes for an...
