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

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 ...

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

Boreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

Journal of Anatomy, EarlyView.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Size-assortative mating in simultaneous hermaphrodites: an experimental test and a meta-analysis [PDF]

, 2015
Assortative mating by size has been argued to be widespread in the animal kingdom. However, the strength of size-assortative mating is known to vary considerably between species and the underlying mechanisms promoting this inter-specific variation remain
