Animal Movement - tracking and modelling

Animal Movement - tracking and modelling

Tracking of animal movements is a fundamental part of biological research. Rapid technological advances allow more and more details to be revealed, but do also increase the needs for models dealing with the vast amount of data. In this Virtual issue we highlight some of the many papers focusing on tracking and modelling of animal movements published in the Nordic Society Oikos journals. The issue is especially compiled for the CAnMove [www.CAnMove.lu.se] symposium ‘Bridging the gap between modelling and tracking data’ held in Lund in February 2016.

Ecography, Oikos and Journal of Avian Biology all have a strong tradition of publishing papers on all aspects of animal movements and we hope that you will find this thematic virtual issue especially interesting. All the papers are freely available for everyone to enjoy.

Into darkness: unravelling the structure of soil food webs

Into darkness: unravelling the structure of soil food webs 2014

While most people know the aboveground part of forest ecosystems, very few have caught a glimpse of the belowground environment that comprises a highly diverse fauna. The number of species co-occurring on less than a square meter habitat ground (or a cubic meter of habitat volume) exceeds that of the aboveground compartment by far. In consequence, forest soil communities have been called “poor man's rainforest”. Nevertheless, we still do not know much about the animals living in these “next-door” habitats and the structure of their communities.

Why is our knowledge about forest soil communities so limited? Progress in our understanding of soil communities and processes has been hampered by the chronic lack of data for complex soil food webs of high resolution. This is caused by aggregation of populations in coarse functional groups, whose species often span multiple trophic levels from primary to secondary or tertiary predators. In addition, soil is an opaque medium leading to a limited visibility of interactions. Further, detritivores typically ingest a multitude of intermingled resources hampering identification of what the animals actually digest and live on. In the recent years, new molecular methods have emerged providing the possibility to unravel belowground interactions and the complex structure of forest soil food webs.

The special issue “Into darkness” comprises several studies of central European beech forest soil communities. The studies included in this special feature fill employ state-of-the-art methods to unravel general feeding guilds by stable isotopes (Klarner et al.) as well as specific directed feeding interactions by molecular gut content and fatty-acid analyses (Ferlian and Scheu, Günther et al., Heidemann et al.). This allowed the construction of the first highly-resolved complex soil food webs (Digel et al.) and analyses how they respond to external drivers such as the nutrient stoichiometry of the basal litter (Ott et al.) and climate change (Lang et al.). Together, they provide a unique impression of a voyage into darkness.

Dispersal Evolution and Species’ Range

Dispersal Evolution and Species’ Range 2014

The distribution of species in space and time is one of the oldest puzzles in ecology. Today we know of many factors that influence species' ranges. However, the ecological and evolutionary interactions of these factors, which ultimately shape the geographical distributions of species are still not comprehensively understood.

In this virtual special issue we aim at providing an overview of the different factors that influence dispersal evolution and species' ranges. These eco-evolutionary forces may act at all levels of biological organization, from genes to (meta-)communities.

The studies collected here highlight that the complexities and non-linearities, which arise from these interactions, challenge our understanding of abundances and distributions. Consequently, it is of great importance to keep in mind that species and their traits are constantly and maybe rapidly evolving and that a whole range of ecological and evolutionary forces influence where they are, and why. This awareness is central for conservation, management and any kind of predictive ecology, especially since our climate and environment at large is permanently changing.

Surf & Turf 2013

Edited by Randi Rotjan

The goal of a truly synthetic, cross-systems ecology has been often lauded but rarely implemented. Here, our authors have embraced the challenge to achieve synthesis via a multi-paper dialogue and we hope this format will act as a springboard for new ecological ideas, experiments and theories.

Partial Migration front cover

Partial Migration – CAnMove 2011

Edited by Ben B. Chapman, Christer Brönmark, Jan-Åke Nilsson and Lars-Anders Hansson

Partial migration, where populations consist of both migratory and resident individuals, is widespread in nature and can have important ecological consequences. CAnMove, a VR-funded research constellation into the ecology and evolution of animal movement, recently hosted a symposium in partial migration at Lund University. From this meeting a number of original research articles were compiled to produce this thematic on partial migration, with the aim of synthesising ideas from a broad range of taxa and improving understanding of the causes and consequences of this phenomenon.

Sizemic Special Issue - Body Size and Ecosystem Dynamics

Body size and ecosystem dynamics - SIZEMIC 2010

Edited by Julia L. Blanchard, Andrea Belgrano, Bo Ebenman, Owen L. Petchey and F.J. Frank Van Veen

Body size influences many processes, ranging from individual biological rates up to the structure of food webs, resilience of ecosystems and their services. The ESF funded research network, SIZEMIC, has been synthesising ideas across pure and applied ecology and in both terrestrial and aquatic realms to improve understanding on the role of body size in ecosystems.
