Data from: Dietary changes in predators and scavengers in a nocturnally illuminated riparian ecosystemAlessandro Manfrin, David Lehmann, Roy H.A. Van Grunsven, Stefano Larsen, Jari Syväranta, Geraldene Wharton, Christian C. Voigt, Michael T. Monaghan, Franz Hölker & Roy H. A. Van Grunsven
Aquatic and terrestrial ecosystems are linked by fluxes of carbon and nutrients in riparian areas. Processes that alter these fluxes may therefore change the diet and composition of consumer communities. We used stable carbon isotope (δ13C) analyses to test whether the increased abundance of aquatic prey observed in another study led to a dietary shift in riparian consumers in areas illuminated by artificial light at night (ALAN). We measured the contribution of aquatic-derived carbon to...
Data from: Pushing the limits of photoreception in twilight conditions: The rod-like cone retina of the deep-sea pearlsidesFanny De Busserolles, Fabio Cortesi, Jon Vidar Helvik, Wayne I. L. Davies, Rachel M. Templin, Robert K. P. Sullivan, Craig T. Michell, Jessica K. Mountford, Shaun P. Collin, Xabier Irigoien, Stein Kaartvedt & Justin Marshall
Most vertebrates have a duplex retina comprising two photoreceptor types, rods for dim-light (scotopic) vision and cones for bright-light (photopic) and color vision. However, deep-sea fishes are only active in dim-light conditions; hence, most species have lost their cones in favor of a simplex retina composed exclusively of rods. Although the pearlsides, Maurolicus spp., have such a pure rod retina, their behavior is at odds with this simplex visual system. Contrary to other deep-sea fishes,...
Data from: Maternal effects in vulnerability to eye-parasites and correlations between behaviour and parasitism in juvenile Arctic charrRaine Kortet, Tiina Lautala, Jukka Kekäläinen, Jouni Taskinen & Heikki Hirvonen
Hatchery-reared fish show high mortalities after release to the wild environment. Explanations for this include potentially predetermined genetics, behavioural and physiological acclimation to fish farm environments, and increased vulnerability to predation and parasitism in the wild. We studied vulnerability to Diplostomum spp. parasites (load of eye-flukes in the lenses), immune defence (relative spleen size) and anti-predator behaviours (approaches toward predator odour, freezing, and swimming activity) in hatchery-reared juvenile Arctic charr (Salvelinus alpinus) using a nested...
Data from: Trade-offs in berry production and biodiversity under prescribed burning and retention regimes in Boreal forestsGustaf Granath, Jari Kouki, Samuel Johnson, Osmo Heikkala, Antonio Rodríguez & Joachim Strengbom
1. Green tree retention and prescribed burning are practices used to mitigate negative effects of forestry. Beside their effects on biodiversity, these practices should also promote non-timber forest products (NTFPs). We assessed: (1) how prescribed burning and tree retention influence NTFPs by examining production of bilberry Vaccinium myrtillus and cowberry; Vaccinium vitis-idaea (2) if there are synergies or trade-offs in the delivery of these NTFPs in relation to delivery of species richness, focusing on five...
As global biodiversity continues to decline steeply, it is becoming increasingly important to understand diversity patterns at local and regional scales. Changes in land use and climate, nitrogen deposition and invasive species are the most important threats to global biodiversity. Because land use changes tend to benefit a few species but impede many, the expected outcome is generally decreasing population sizes, decreasing species richness at local and regional scales, and increasing similarity of species compositions...
Data from: Breeding bird species diversity across gradients of land use from forest to agriculture in EuropeMatti J. Koivula, Dan E. Chamberlain, Robert J. Fuller, Stephen C. F. Palmer, Attila Bankovics, Fintan Bracken, Tom Bolger, Eduardo De Juana, Marc Montadert, Renato Neves, Rui Rufino, Angel Sallent, Luís Lopes Da Silva, Pedro J. Leitão, Manfred Steffen & Allan D. Watt
Loss, fragmentation and decreasing quality of habitats have been proposed as major threats to biodiversity world-wide, but relatively little is known about biodiversity responses to multiple pressures, particularly at very large spatial scales. We evaluated the relative contributions of four landscape variables (habitat cover, diversity, fragmentation and productivity) in determining different components of avian diversity across Europe. We sampled breeding birds in multiple 1-km2 landscapes, from high forest cover to intensive agricultural land, in eight...
Data from: Metabolic rate associates with, but does not generate covariation between, behaviours in western stutter-trilling crickets, Gryllus integerIndrikis A. Krams, Petri T. Niemelä, Giedrius Trakimas, Ronalds Krams, Gordon M. Burghardt, Tatjana Krama, Aare Kuusik, Marika Mand, Markus J. Rantala, Raivo Mand, Jukka Kekäläinen, Ilkka Sirkka, Severi Luoto, Raine Kortet & Indrikis Krams
The causes and consequences of among-individual variation and covariation in behaviours are of substantial interest to behavioural ecology, but the proximate mechanisms underpinning this (co)variation are still unclear. Previous research suggests metabolic rate as a potential proximate mechanism to explain behavioural covariation. We measured the resting metabolic rate (RMR), boldness and exploration in western stutter-trilling crickets, Gryllus integer, selected differentially for short and fast development over two generations. After applying mixed-effects models to reveal the...
Sciatica or the sciatic syndrome is a common and often disabling low back disorder in the working-age population. It has a relatively high heritability but poorly understood molecular mechanisms. The Finnish population is a genetic isolate where small founder population and bottleneck events have led to enrichment of certain rare and low frequency variants. We performed here the first genome-wide association (GWAS) and meta-analysis of sciatica. The meta-analysis was conducted across two GWAS covering 291...
Data from: Distribution and functionality of copy number variation across European cattle populationsMaulik Upadhyay, Vinicius H. Da Silva, Hendrik-Jan Megens, Marleen H. P. W. Visker, Paolo Ajmone-Marsan, Valentin A. Bâlteanu, Susana Dunner, Jose Fernando Garcia, Catarina Ginja, Juha Kantanen, Martien A.M. Groenen, Richard P.M.A. Crooijmans, Vinicus H. Da Silva, Martien A. M. Groenen & Richard P. M. A. Crooijmans
Copy number variation (CNV), which is characterized by large-scale losses or gains of DNA fragments, contributes significantly to genetic and phenotypic variation. Assessing CNV across different European cattle populations might reveal genetic changes responsible for phenotypic differences, which have accumulated throughout the domestication history of cattle as consequences of evolutionary forces that act upon them. To explore pattern of CNVs across European cattle, we genotyped 149 individuals, that represent different European regions, using the Illumina...
