Century‐Scale Changes in the Feeding Patterns of Demersal Fish Species in the Western North Sea

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Understanding the extent and magnitude of change in marine food webs requires historical data that predates modern monitoring efforts. Such information can provide invaluable insights into the longer‐term impacts of altered trophic interactions, yet it is rarely incorporated into marine policy frameworks.

Shell use by the hermit crab Calcinus californiensis at different levels of the intertidal zone

open access: yesScientia Marina, 2011
The gastropod shell use of the hermit crab Calcinus californiensis was studied at Troncones, Guerrero, México. Hermit crabs were captured at two different levels of the intertidal zone, in wave-protected and wave-exposed sites. C. californiensis occupied

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Scaling of olfactory antennae of the terrestrial hermit crabs Coenobita rugosus and Coenobita perlatus during ontogeny [PDF]

open access: yes, 2014
Although many lineages of terrestrial crustaceans have poor olfactory capabilities, crabs in the family Coenobitidae, including the terrestrial hermit crabs in the genus Coenobita, are able to locate food and water using olfactory antennae (antennules ...

Novel Approach to Inter‐Onset‐Interval Ratio Uncovers Music‐Like Rhythmic Patterns in Budgerigar (Melopsittacus undulatus) Warble Song

open access: yesAnnals of the New York Academy of Sciences, EarlyView.
ABSTRACT Rhythm is an essential part of human music. Recently, there has been a surge of interest in the production of rhythmicity in nonhuman animal vocalizations. Novel methods have found widespread rhythmic behaviors—including those with music‐like properties—among nonhuman animals.

Expression of ionotropic receptors in terrestrial hermit crab’s olfactory sensory neurons

open access: yesFrontiers in Cellular Neuroscience, 2015
Coenobitidae are one out of at least five crustacean lineages which independently succeeded in the transition from water to land. This change in lifestyle required adaptation of the peripheral olfactory organs, the antennules, in order to sense chemical ...

Weak rappers rock more: Hermit crabs assess their own agonistic behaviour. [PDF]

open access: yes, 2016
Fighting animals use a variety of information sources to make strategic decisions. A neglected potential source of information is an individual’s own performance during a fight.

Microbial influence on the formation and subsequent changes of vertebrate tracks: field experiments on present‐day coastal sediments

open access: yesSedimentology, EarlyView.
ABSTRACT The presence of microbial mats is often invoked to explain the good preservation of vertebrate tracks, because they can cover and biostabilize such structures. However, microbial influence on the sediment properties when the track is made and on the track characteristics has not been so thoroughly analysed.

Shell occupation by the hermit crab Dardanus insignis (Decapoda, Diogenidae) from the north Coast of São Paulo state, Brazil

open access: yesBrazilian Journal of Biology
The pattern of shell occupation by the hermit crab Dardanus insignis (Saussure, 1858) from the subtropical region of southeastern coast of Brazil was investigated in the present study. The percentage of shell types that were occupied and the morphometric

Epibenthic communities of trawlable grounds of the Cantabrian Sea

open access: yesScientia Marina, 2006
Epibenthic communities of the Cantabrian shelf were sampled in October 2000 and October 2001 using a 3.5 m beam trawl. The surveys were undertaken following a pattern of stratified sampling in four transects perpendicular to the coastline and included ...
