Freire; Casper Gundelund; Kieran Hyder; Ivan Jarić; Robert Lennox; Wolf‑Christian Lewin; Abigail J. Lynch; Stephen R. Midway; Warren M. Potts; Karina L. Ryan; Christian Skov; Harry V. Strehlow; Sean R. Tracey; Jun‑ichi Tsuboi; Paul A. Venturelli; Jessica L. Weir; Marc Simon Weltersbach; Steven J. Cooke

The study investigated the impact of COVID on recreational fisheries across the globe.The authors found COVID to increase local recreational fisheries participation but to reduce touristic recreational fisheries where travel restrictions were in place.

To save sturgeons, we need river channels around hydropower dams

Liang Zhanga; Haijun Wanga; Jörn Gessner; Leonardo Congiub; Tim J. Haxton; Erik Jeppesen; Jens-Christian Svenning; Ping Xie

Weirs and other transverse structures in rivers not only impede migratory fish on their way to spawning grounds, but even if they are able to pass, many of them die in the turbines of hydroelectric power plants. The authors present a recommendation on how to facilitate effective passage and even promote sturgeon with bypass channels at dams that can serve as additional habitat.

The European freshwater landscape and hotspot areas of mass effects and regional connectivity

David Cunillera-Montcusí; Jordi Bou; Thomas Mehner; Sandra Brucet; Matías Arim; Ana I. Borthagaray

The authors detected great concentrations of source hotspots on the northern regions associated to lentic ecosystems, main European rivers acting as ecological corridors for all freshwaters, and a mixed distribution of connectivity hotspots in southern and Mediterranean ecoregions.

Socio-economic or environmental benefits from pondscapes? Deriving stakeholder preferences using analytic hierarchy process and compositional data analysis

Hoang-Tien Vo; Maria Vrachioli; Fabian Frick; Johannes Sauer; Sandra Brucet Balmana; Lluís Benejam Vidal; Thomas Mehner; Pieter Lemmens; Beat Oertli; Aurelie Boissezon; Meryem Beklioglu; Antoine Dolcerocca; Mariana Meerhoff

The authors studied the needs and knowledge of stakeholders who own, work, research, or benefit from pondscapes in 8 countries. Using the analytic hierarchy process, this study shows that in general stakeholders in the European and Turkish demo-sites prefer environmental benefits, while stakeholders in the Uruguayan demo-sites rank the economic benefits higher.

Massive expansion of sex-specific SNPs, transposon-related elements, and neocentromere formation shape the young W-chromosome from the mosquitofish Gambusia affinis

Stefan Müller; Kang Du; Yann Guiguen; Maria Pichler; Shinichi Nakagawa; Matthias Stöck; Manfred Schartl; Dunja K. Lamatsch

The mosquitofish Gambusia affinis, globally introduced to fight mosquitos, is a threat for freshwater ecosystems and a model for sex chromosome evolution. Cyto-/genomics reveals a neocentromere to shield parts of its evolutionary young female sex chromosome (W) that actively differentiates by expansion of transcribed transposons, while major sequence divergence or gene decay are missing.

Multispecies collective waving behaviour in fish

Juliane Lukas; Jens Krause; Arabella Sophie Träger; Jonas Marc Piotrowski; Pawel Romanczuk; Henning Sprekeler; Lenin Arias-Rodriguez; Stefan Krause; Christopher Schutz; David Bierbach

Groups composed of more than one species offer a unique opportunity to look into the evolution of both mechanistic and functional aspects of collective behavior. The study presents data on mixed-species fish shoals that perform collective dives. The dampening effect of less responsive gambusia on molly diving behavior can have strong evolutionary consequences on the overall collective behavior.

Ecosystem-based management outperforms species-focused stocking for enhancing fish populations

Johannes Radinger; Sven Matern; Thomas Klefoth; Christian Wolter; Fritz Feldhege; Christopher T. Monk; Robert Arlinghaus

In a large-scale effort, a research team in cooperation with angling clubs, has conducted whole-lake experiments in 20 lakes to improve ecological conditions. Habitat improvements were the most effective means to enhance fish populations, whereas fish stocking completely failed. The study emphasizes the importance of restoring habitats and improving natural ecosystem processes.

Leveraging big data to uncover the eco-evolutionary factors shaping behavioural development

Sean M. Ehlman; Ulrike Scherer; David Bierbach; Fritz A. Francisco; Kate L. Laskowski; Jens Krause; Max Wolf

In this review, the authors provide a guide to state-of-the-art approaches that allow the collection and analysis of high-resolution behavioural data across development. They outline how such approaches can be used to address key issues regarding the ecological and evolutionary factors shaping behavioural development.

Trophic Transfer Efficiency in Lakes

Thomas Mehner; Katrin Attermeyer; Mario Brauns; Soren Brothers; Sabine Hilt; Kristin Scharnweber; Renee Mina van Dorst; Michael J. Vanni; Ursula Gaedke

The authors explored how spatial and temporal variability of lake food webs and their links to the terrestrial environment affect trophic transfer efficiency (TTE). They suggest that TTE can be estimated as mechanistic expression of energy flow between consumer and producer pairs, or as ecosystem efficiency comparing total sums of heterotrophic production rates with fixation rates of carbon.
