Integrative Zoology, EarlyView.Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Texas coastal zone biotopes : an ecography : interim report for the Bay and Estuary Management Program (CRMP) [PDF]
, 1972 November 1972Because esthetics, biological environment and physiography are so interrelated and have changeable meanings in various environments, we are obligated to think of the environment in terms of biological change, as environmental protection is ...

Acta Zoologica, EarlyView.ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Robotic crabs reveal that female fiddler crabs are sensitive to changes in male display rate [PDF]
, 2018 Males often produce dynamic, repetitive courtship displays that can be demanding to perform and might advertise male quality to females. A key feature of demanding displays is that they can change in intensity: escalating as a male increases his ...

Orchard Management Influences Predation of Halyomorpha halys Eggs
Entomologia Experimentalis et Applicata, EarlyView.We investigated predation of eggs of the invasive stink bug Halyomorpha halys on apple trees in conventional, organic, and extensively managed Dutch orchards. Predation exceeded 40% in extensively managed orchards but was only about 10% in conventional and organic ones. We used camera traps to reveal natural enemies that may contribute to H.

'Selfish herds' of guppies follow complex movement rules, but not when information is limited [PDF]
, 2015 Under the threat of predation, animals can decrease their level of risk by moving towards other individuals to form compact groups. A significant body of theoretical work has proposed multiple movement rules, varying in complexity, which might underlie ...

CHIMNEY BUILDING IN THE FIDDLER CRAB UCA ARCUATA [PDF]
Journal of Crustacean Biology, 2000 Abstract The fiddler crab Uca arcuata (De Haan, 1835), which lives on intertidal mud flats, occasionally builds a cylindrical mud chimney that encircles its burrow entrance. Chimneys were more often found with burrows of females than with those of males (22% versus 10%).

Hedgehog Pillows and Squirrel Plates: Priming Semantic Structure in Children's Comprehension
Language Learning, EarlyView.Abstract We report three expression–picture‐matching experiments targeting preschoolers’ semantic processing. We assessed whether 3‐ and 4‐year‐olds’ interpretations of ambiguous novel noun–noun combinations (e.g., hedgehog pillow) were affected by immediate language experience and what role lexical items played in this process.
