Data from: Producers and scroungers: feeding type composition changes with group size in a socially foraging spider

Marlis Dumke, Mariella E. Herberstein, Jutta M. Schneider & Marie E. Herberstein
In groups of socially foraging animals, feeding behaviour may change with group size in response to varying cost-benefit trade-offs. Numerous studies have described group size effects on group-average feeding behaviour, particularly emphasizing an increase in scrounging incidence for larger groups, where individuals (scroungers) feed from the food sources others (producers) discovered. However, individual variation in feeding behaviour remains unconsidered in the vast majority of these studies even though theoretical models presume individuals to specialize in...

Data from: The nutritional balancing act of a large herbivore: an experiment with captive moose (Alces alces L)

The nutrient balancing hypothesis proposes that, when sufficient food is available, the primary goal of animal diet selection is to obtain a nutritionally balanced diet. This hypothesis can be tested using the Geometric Framework for nutrition (GF). The GF enables researchers to study patterns of nutrient intake (e.g. macronutrients; protein, carbohydrates, fat), interactions between the different nutrients, and how an animal resolves the potential conflict between over-eating one or more nutrients and under-eating others during...

Data from: Predator encounters have spatially extensive impacts on parental behaviour in a breeding bird community

Predation risk has negative indirect effects on prey fitness, partly mediated through changes in behaviour. Evidence that individuals gather social information from other members of the population suggests that events in a community may impact the behaviour of distant individuals. However, spatially wide-ranging impacts on individual behaviour caused by a predator encounter elsewhere in a community have not been documented before. We investigated the effect of a predator encounter (hawk model presented at a focal...

Data from: Socially cued developmental plasticity in web-building spiders

Rainer Neumann & Jutta M. Schneider
Background: Socially cued anticipatory plasticity (SCAP) has been proposed as a widespread mechanism of adaptive life-history shifts in semelparous species with extreme male mating investment. Such mating systems evolved several times independently in spiders and male reproductive success should critically depend on timely maturation and rapid location of a receptive and, ideally, virgin female. We experimentally investigated socially cued anticipatory plasticity in two sympatric, closely related Nephila species that share many components of their mating...

Data from: Biofilm morphotypes and population structure among Staphylococcus epidermidis from commensal and clinical samples

Llinos Harris, Susan Murray, Ben Pascoe, James Bray, Guillaume Meric, Leonardos Magerios, Thomas S. Wilkinson, Rose E. Jeeves, Holger Rohde, Stefan Schwarz, Herminia De Lencastre, Maria Miragaia, Joana Rolo, Rory Bowden, Keith A. Jolley, Martin C. J. Maiden, Dietrich Mack, Samuel Sheppard, Llinos G. Harris, Rose Jeeves & Samuel K. Sheppard
Bacterial species comprise related genotypes that can display divergent phenotypes with important clinical implications. Staphylococcus epidermidis is a common cause of nosocomial infections and, critical to its pathogenesis, is its ability to adhere and form biofilms on surfaces, thereby moderating the effect of the host’s immune response and antibiotics. Commensal S. epidermidis populations are thought to differ from those associated with disease in factors involved in adhesion and biofilm accumulation. We quantified the differences in...

Data from: Carry-over effects of conditions at the wintering grounds on breeding plumage signals in a migratory bird: roles of phenotypic plasticity and selection

Pauliina E. Järvistö, Sara Calhim, Wiebke Schuett, Päivi Maria Sirkiä, William Velmala & Toni Laaksonen
To understand the consequences of ever-changing environment on the dynamics of phenotypic traits, distinguishing between selection processes and individual plasticity is crucial. We examined individual consistency/plasticity in several male secondary sexual traits expressed during the breeding season (white wing and forehead patch size, UV reflectance of white wing patch and dorsal melanin colouration) in a migratory pied flycatcher (Ficedula hypoleuca) population over an 11-year period. Furthermore, we studied carry-over effects of three environmental variables (NAO,...

Data from: Direct effects of microalgae and protists on herring (Clupea harengus) yolk sac larvae

Björn Illing, Marta Moyano, Jan Niemax & Myron Arms Peck
This study investigated effects of microalgae (Rhodomonas baltica) and heterotrophic protists (Oxyrrhis marina) on the daily growth, activity, condition and feeding success of Atlantic herring (Clupea harengus) larvae from hatch, through the end of the endogenous (yolk sac) period. Yolk sac larvae were reared in the presence and absence of microplankton and, each day, groups of larvae were provided access to copepods. Larvae reared with microalgae and protists exhibited precocious (2 days earlier) and ≥...
