Beyond preferences for particular species of tree, bark-foraging birds are associated with various tree characteristics such as decay stage, trunk diameter, or bark roughness. Our objectives were to study the winter foraging ecology of different bark-foraging bird species in the highly diverse floodplain forests of Donau-Auen National Park (Austria...

Increasing human activity is altering the structure of forests, which affects the composition of communities, including birds. However, little is known about the key forest structure variables that determine the richness of bird communities in European temperate oak forests. We, therefore, aimed to identify key variables in these habitats that coul...

Springtails (Collembola) inhabit soils from the Arctic to the Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database on springtail communities that includes 249,912 occurrences from 44,999 samples and 2,990 sites. These data are mainly raw sample-level records at the s...

More than 120 years have passed since the Czech scientist Karel Absolon registered the first species of springtails in the territory of today's Montenegro and then described it as new for science. After him, in the first half of the XX century, a couple of European experts described new species based on material from the territory of Montenegro. Ho...

Collembola are a separate class of hexapod arthropods and an indispensable member of the soil mesofauna. Over 9,000 species are classified into four recent orders: Poduromorpha Börner, 1913; Entomobryomorpha Börner, 1913; Symphypleona Börner, 1901, and Neelipleona Massoud, 1971. Poduromorphic springtails have an elongated and distinctly segmented b...

The black locust (Robinia pseudoacacia L.) is the second-most abundant deciduous tree in forest plantations, and one of the most important invasive woody species worldwide.
