Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

open access: yesActa 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 ...

Crab spider vision improves their prey capture despite low visual system investment [PDF]

open access: yesRoyal Society Open Science
Crab spiders (Thomisidae) are well-known predators, typically ambushing prey upon flowers and other plants. This style of predation suggests a potential benefit from vision in prey capture by crab spiders despite their comparatively small eyes.

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

open access: yesConservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

That sinkin’ feeling: Environmentally induced distress on a disappearing island

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract Residents of Tangier Island, Virginia, a subsiding island in the Chesapeake Bay, embody psychosocial dimensions of environmental change. Analysis of ethnographic data shows islanders’ experiences and articulations of anxiety, panic, and despair as “that sinkin’ feeling,” resulting from the stress of living with the long‐term threat of imminent

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs

open access: yesPhysiological Entomology, EarlyView.
In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

Re-description of Xysticus bimaculatus L. Koch, 1867 (Araneae, Thomisidae) and characterization of its subsocial lifestyle

open access: yesZooKeys, 2014
Spiders have become an important model to study the evolution of sociality, but a lack of their detailed natural history and taxonomy hinders broader comparative studies.

HARVESTMEN AS COMMENSALS OF CRAB SPIDERS

open access: yesJournal of Arachnology, 2001
Abstract Harvestmen Phalangium opilio regularly feed upon the carcasses of bees and moths discarded by crab spiders Misumena vatia Clerck 1757 hunting on flowers. I report one observation of a harvestman unsuccessfully attempting to secure a bee still being fed on by a crab spider.

ABSTRACT An identity transition refers to changes in self‐concept that can result from professional or personal shifts. Although organizations increasingly support institutionally legible and culturally normative nonwork transitions, others remain professionally stigmatized or culturally unspeakable.

Patterns of juvenile habitat use by the spider crab Maja brachydactyla as revealed by stable isotope analyses

open access: yesScientia Marina, 2009
Patterns of habitat use by spider crab juveniles, Maja brachydactyla, from two geographic areas on the NW coast of the Iberian Peninsula were studied through the analysis of carbon and nitrogen stable isotope relations in muscle and hepatopancreas.
