TLDR
Results suggest that, for U. pugilator, body size plays a large role in the preference for exposed habitat, and interacts between origin habitat and carapace width and activity level.Abstract:
Recognizing which phenotypic traits are predictors for habitat choice can have important implications for understanding population dynamics. This study determined whether body size, sex, activity level, or origin habitat affected the preference of the fiddler crab, Uca pugilator, in selecting either a marsh or open mudflat, two habitats differing in risk level and food availability. Combining field and laboratory experiments, this study indicated a significant difference in body size and activity level of crabs between habitats. Further investigation of phenotypic dependency on habitat preference resulted in interactions between origin habitat and carapace width and activity level. When split by origin habitat, habitat preference for the open mudflat was predicted by body size for crabs originating from the open mudflat and by activity level for the crabs originating from the Spartina marsh. These results suggest that, for U. pugilator, body size plays a large role in the preference for exposed habitat.read more

TL;DR: The study shows that behavioral variation cannot be explained by just one factor like POLS at different hierarchical levels, but rather by a combination of factors including the animals’ life-history and ecological and physiological background.

Fitting Linear Mixed-Effects Models Using lme4
TL;DR: In this article, a model is described in an lmer call by a formula, in this case including both fixed-and random-effects terms, and the formula and data together determine a numerical representation of the model from which the profiled deviance or the profeatured REML criterion can be evaluated as a function of some of model parameters.

Causes and consequences of animal dispersal strategies: relating individual behaviour to spatial dynamics.
Diana E. Bowler,Tim G. Benton +1 more
TL;DR: Logistical difficulties preclude a detailed study of dispersal for many species, however incorporating unrealistic dispersal assumptions in spatial population models may yield inaccurate and costly predictions, and further studies are necessary to explore the importance of incorporating specific condition‐dependent dispersal strategies for evolutionary and population dynamic predictions.

Tests for emotionality in rats and mice: a review.
TL;DR: Findings clearly failed to support the use of emotionality as a consistent constitutional trait, with unitary drive properties, in ‘novel environment’ tests (e.g. emergence tests, active avoidance learning).

Informed dispersal, heterogeneity in animal dispersal syndromes and the dynamics of spatially structured populations
TL;DR: Recent literature providing strong evidence that individual variation in dispersal has an important impact on both reinforcement and colonization success and therefore must be taken into account when predicting ecological responses to global warming and habitat fragmentation is discussed.

TL;DR: The consequences of the presence and magnitude of different costs during different phases of the dispersal process, and their internal organisation through covariation with other life‐history traits are synthesised with respect to potential consequences for species conservation and the need for development of a new generation of spatial simulation models.
