Collective memory and spatial sorting in animal groups.
TLDR
The first evidence for collective memory is presented in such animal groups (where the previous history of group structure influences the collective behaviour exhibited as individual interactions change) during the transition of a group from one type of collective behaviour to another. Expand
Avoiding Attack: The Evolutionary Ecology of Crypsis, Warning Signals and Mimicry
TLDR
A comparison of Batesian and Mullerian Mimicry with mathematical and computer models that deal with Mullerian mimcry found that Batesian mimicry is superior to Mullerian mimicry in terms of both accuracy and efficiency. Expand
The unequal variance t-test is an underused alternative to Student's t-test and the Mann–Whitney U test
TLDR
The aim in this forum article is to argue for the greater use of the last of these tests, the t-test for unequal variances, which is not commonly used. Expand
Time for some a priori thinking about post hoc testing
TLDR
The aim in this note is to briefly survey current practice in this regard and to provide clear guidance on how such testing might most appropriately be carried out in different instances. Expand
Sandeel recruitment in the North Sea: demographic, climatic and trophic effects
TLDR
A negative relationship was detected between recruitment and the winter index of the North Atlantic Oscillation, which affects sea temperatures during the egg and larval period, and the findings suggest that climate change may impact upon sandeel populations in the North Sea. Expand
Interspecific information transfer influences animal community structure.
TLDR
It is reviewed that research indicates that heterospecific information is a driving factor in the formation or maintenance of temporary or stable mixed-species groups, and the morphological, ecological and behavioral factors that make some species information sources and others information seekers. Expand
Refuge use by fish as a function of body length–related metabolic expenditure and predation risks
TLDR
The results suggest that larger fish are subject to lower predation risks and are less affected by food deprivation than small fish, with fish decreasing their responses to food–deprivation treatments more strongly with increasing body length than to predation treatments. Expand
Dynamics of mercury in blood and feathers of great skuas
TLDR
Blood and feathers of captive great skuas were monitored and mercury concentrations in feathers were significantly correlated with those in blood at the time of their growth, suggesting that blood and feathers reflect mercury intake over the same time period. Expand
USING ARTIFICIAL NESTS TO TEST IMPORTANCE OF NESTING MATERIAL AND NEST SHELTER FOR INCUBATION ENERGETICS
TLDR
The results suggest that nest construction may have an important bearing on the subsequent costs of reproduction, and that important trade-offs may exist between nest construction for reduced thermodynamic costs, and other costs and benefits of nest-building and reproduction. Expand
Swarm intelligence in animals and humans.
TLDR
Approaches from seemingly disparate areas are tied together by means of a general definition of SI to unite SI work on both animal and human groups and propose areas in which further progress with SI research can be made. Expand
