Post-restoration grassland management overrides the effects of restoration methods in propagule-rich landscapes

Grassland restoration is gaining momentum worldwide to tackle the loss of biodiversity and associated ecosystem services. Restoration methods and their effects on ecological community reassembly have been extensively studied across various grassland types, while the importance of post-restoration management has so far received less attention. Grassland management is an important surrogate for natural disturbances, which most ancient grasslands have co-evolved with. Thus, without the reintroduction of management-related disturbance, restoration targets are unlikely to be achieved...

Comparison of foraging tool use in two species of myrmicine ants (Hymenoptera: Formicidae)

Gábor Lőrinczi, Gábor Módra, István Maák & Ádám Lőrincz
The tool-using behavior of Aphaenogaster species has been well studied in the past few years, however, our knowledge of other myrmicine ants is rather limited. The aim of the present study was to compare the tool-using behavior of two closely related myrmicine ants with different feeding behaviors: Aphaenogaster subterranea, an omnivorous species, and Messor structor, a mainly granivorous species, which is also known to use tools when feeding on liquids. We tested the hypothesis that...

Impact of shrub cover and wild ungulate browsing on the vegetation of restored mountain hay meadows

Grasslands of middle mountain regions are among the most diverse habitats of the Carpathian Basin, but they are threatened by spontaneous succession leading to woody encroachment. It is a high priority of nature conservation to preserve these diverse habitats by suppressing the woody encroachment and to create new open habitat patches by scrub removal. The main goal of this study was to investigate the effect of shrub cover on plant species composition and vegetation in...

Predominantly linear summation of metabotropic postsynaptic potentials follows coactivation of neurogliaform interneurons

Attila Ozsvár, Gergely Komlósi, Gáspár Oláh, Judith Baka, Gábor Molnár & Gábor Tamás
Summation of ionotropic receptor-mediated responses is critical in neuronal computation by shaping input-output characteristics of neurons. However, arithmetics of summation for metabotropic signals are not known. We characterized the combined ionotropic and metabotropic output of neocortical neurogliaform cells (NGFCs) using electrophysiological and anatomical methods. These experiments revealed that GABA receptors are activated up to 1.8 microns from release sites and confirmed coactivation of putative NGFCs in superficial cortical layers in vivo. Triple recordings from presynaptic...

Turning old foes into new allies – harnessing drainage canals for biodiversity conservation in a desiccated European lowland region

1. Drainage canals are widespread components of agricultural landscapes. Although canals have greatly contributed to biodiversity loss by desiccating wetlands, they have recently attracted conservation attention due to their potential to function as refugia for native species in intensively managed landscapes. However, their conservation role in complex landscapes composed of agricultural fields and desiccated but otherwise untransformed, semi-natural habitats, on which canals still pose a heavy burden, is unknown. Improved understanding of drainage canals and...
