Data from: A unified model for optimizing riverscape conservation

Tibor Erõs, Jesse R. O'Hanley & István Czeglédi
1.Spatial prioritization tools provide a means of finding efficient trade-offs between biodiversity protection and the delivery of ecosystem services. Although a large number of prioritization approaches have been proposed in the literature, most are specifically designed for terrestrial systems. When applied to river ecosystems, they often fail to adequately account for the essential role that landscape connectivity plays in maintaining both biodiversity and ecosystem services. This is particularly true of longitudinal connectivity, which in many...

A practical approach to measuring the acoustic diversity by community ecology methods

Sándor Zsebők, Dénes Schmera, Miklós Laczi, Gergely Nagy, Éva Vaskuti, János Török & László Garamszegi
The study of the diversity of animal signals on within- and among-species levels is the key to uncover mechanisms that shape the evolution of communication systems. However, the methods used to quantify acoustic diversity (like repertoire size) lack to grasp several aspects of acoustic diversity. Here, we propose a new framework for the study of animal communication, in which we decompose the acoustic diversity with the methodological toolbox from community ecology. We explore how different...

Data from: Impact of urbanization on abundance and phenology of caterpillars and consequences for breeding in an insectivorous bird

Gábor Seress, Tamás Hammer, Veronika Bókony, Ernő Vincze, Bálint Preiszner, Ivett Pipoly, Csenge Sinkovics, Karl Evans, András Liker & Karl L. Evans
Urbanization can have marked effects on plant and animal populations’ phenology, population size, predator-prey interactions and reproductive success. These aspects are rarely studied simultaneously in a single system, and some are rarely investigated, e.g. how insect phenology responds to urban development. Here, we study a tri-trophic system of trees – phytophagous insects (caterpillars) – insectivorous birds (great tits) to assess how urbanization influences i) the phenology of each component of this system, ii) insect abundance...

Quantitative monitoring of diverse fish communities on a large scale combining eDNA metabarcoding and qPCR

Didier Pont, Paul Meulenbroek, Vincenz Bammer, Tony Dejean, Tibor Erős, Pauline Jean, Mirjana Lenhardt, Christoffer Nagel, Ladislav Pekarik, Michael Schabuss, Bernhard C. Stoeckle, Elena Stoica, Horst Zornig, Alexander Weigand & Alice Valentini
eDNA metabarcoding is an effective method for studying fish communities but allows only an estimation of relative species abundance (density / biomass). Here, we combine metabarcoding with an estimation of the total abundance of eDNA amplified by our universal marker (teleo) using a qPCR approach to infer the absolute abundance of fish species. We carried out a 2,850 km eDNA survey within the Danube catchment using a spatial integrative sampling protocol coupled with traditional electrofishing...

Data from: A review of the defining chemical properties of soda lakes and pans: an assessment on a large geographic scale of Eurasian inland saline surface waters

Emil Boros & Marina Kolpakova
The aim of this study is to evaluate the definition of water chemical type, with particular attention to soda brine characteristics by assessing ionic composition and pH values on a large geographic scale and broad salinity (TDS) range of Eurasian inland saline surface waters, in order to rectify the considerable confusion about the exact chemical classification of soda lakes and pans. Data on pH and on the concentration of eight major ions were compiled into...
