Evolutionary impact of size-selective harvesting on shoaling behavior: individual-level mechanisms and possible consequences for natural and fishing mortality

Valerio Sbragaglia; Pascal P. Klamser; Pawel Romanczuk; Robert Arlinghaus

The authors present a multigeneration harvest selection experiment with zebrafish as a model to understand the effects of size-selective harvesting on shoaling behavior. Using high-resolution tracking of fish behavior with computational agent-based modeling, they show that shoal cohesion changed in the direction expected by a trade-off between individual vigilance and the use of social cues.

Predator group composition indirectly influences food web dynamics through predator growth rates

Kate L. Laskowski; Marta M. Alirangues Nuñez; Sabine Hilt; Mark O. Gessner; Thomas Mehner

The authors aimed to find empirical support for the theoretically predicted effect of intraspecific behavioral variation on food web dynamics and ecosystem function. In pond experiments, there was no effect of behavioral variation of predators on dynamics of lower trophic levels, but predator mass varied according to group composition, and hence was a strong predictor of food web effects.

Whiteside; Ivan Jarić

The authors present methods that combine high-resolution tracking technologies with Big Data analyses to investigate the movements of fish and other animals. Through high resolution tracking the effects of environmental and climate changes on wildlife can be better understood, and nature and wildlife conservation be advanced on this basis.

Researchers from 90 scientific institutions worldwide have stated that freshwater biodiversity research and conservation lag far behind the efforts  in terrestrial and marine environments. They propose a research agenda with 15 priorities aimed at improving research on biodiversity in lakes, rivers, ponds and wetlands. This is urgently needed as the loss of biodiversity there is dramatic.

Setting robust biodiversity goals

Martine Maron; Diego Juffe-Bignoli; Linda Krueger; Joseph Kiesecker; Noëlle F. Kümpel; Kerry ten Kate; E.J. Milner-Gulland; William N.S. Arlidge; Hollie Booth; Joseph W. Bull; Malcolm Starkey; Jonathan M. Ekstrom; Bernardo Strassburg; Peter H. Verburg; James E. M. Watson

The new global biodiversity framework (GBF) must drive action to reverse the decline of biodiversity. However, the draft goals and targets fail to set out these clear outcomes. The authors propose modifications that would help to reveal the specific contribution of each action and provide clarity on whether the achievement of action targets would be adequate to achieve the outcome goals.

Local disconnects in global discourses: the unintended consequences of marine mammal protection on small-scale fishers

Katrina J. Davis; Joanna Alfaro-Shigueto; William N.S. Arlidge; Michael Burton; Jeffrey C. Mangel; Morena Mills; E.J. Milner-Gulland; José Palma-Duque; Cristina Romero-de-Diego; Stefan Gelcich

Efforts to protect sea lions along South America's west coast have contributed to species recovery, but also to conflict between sea lions and small-scale fisheries. To understand the concerns, the authors assessed how 301 coastal small-scale fishers perceive their interactions with the sea lions. They propose solutions to manage conflict that are sensitive to heterogeneity among fisher groups.

The aquaponic principle - it is all about coupling

Gösta F. M. Baganz; Ranka Junge; Maria C. Portella; Simon Goddek; Karel J. Keesman; Daniela Baganz; Georg Staaks; Christopher Shaw; Frank Lohrberg; Werner Kloas

The authors have tightened up the definitions of aquaponics and created a calculation model for resource use. They argue that the coupling of internal flows, for example of water, nutrients and energy, must be evaluated. After all, it is the cycle idea that ultimately makes aquaponics sustainable.

A duplicated copy of id2b is an unusual sex-determining candidate gene on the Y chromosome of arapaima (Arapaima gigas)

Nóbrega; Céline Lopez-Roques; Carole Iampietro; Jérôme Lluch; Werner Kloas; Sven Wuertz; Fabian Schaefer; Matthias Stöck; Yann Guiguen; Manfred Schartl

The Arapaima is an endangered species of interest for sustainable aquaculture. The authors published an improved genome sequence and identified a Y-linked candidate gene for sex determination in males. A PCR test enables genotyping as a new tool for breeding and conservation of the Arapaima. It has already been used to distinguish males from females at the IGB as well.

Ecological impacts of water-based recreational activities on freshwater ecosystems: a global meta-analysis

Malwina Schafft; Benjamin Wegner; Nora Meyer; Christian Wolter; Robert Arlinghaus

The authors have summarised and evaluated the scientific literature on recreational ecology in a meta-study. Although all recreational activities can have negative impacts on plants, animals and the environment, they conclude that boat traffic and shoreline use have the most consistently negative impacts.
