Age and growth of Callinectes danae (Brachyura: Portunidae) in a tropical region [PDF]

Journal of Crustacean Biology, 2012
Some 2178 male and 2109 female Callinectes danae Smith, 1869 were caught in Northeastern Brazil, from March 2009 through February 2010; we reared 24 males and 24 females for 6 months. The relative growth (relation between weight and cephalothorax width) showed negative allometry, except in adult males.

The value of conditional prediction: Can retained species help predict unknown discards in commercial fisheries?

Journal of Applied Ecology, Volume 62, Issue 6, Page 1392-1405, June 2025.
Due to their higher performance and reliability, we consider SSDMs valuable for modelling unobserved discards and advise caution when using conditional joint prediction for continuous response variables such as biomass, especially when overdispersion is likely.

Brachyura (Crustacea, Decapoda) associated to Schizoporella unicornis (Bryozoa, Gymnolaemata) in Ubatuba bay (SP), Brazil

Brazilian Archives of Biology and Technology, 1998
This work characterizes the composition of Brachyura from Schizoporella unicornis. The samples were collected in 1995 at Itaguá Beach, Ubatuba (SP), at three month intervals, during all seasons from January to December. The Bryozoa colonies were obtained

Wait a Minute? Hiding Behavior of Burrowing Crabs and an Oversized Bill Explain Why Crab Plovers Prefer Armored Swimming Crabs

Ethology, Volume 131, Issue 5, May 2025.
ABSTRACT In the Indo‐West Pacific biogeographical region, a suite of shorebirds searches for crabs as food. While the majority of these shorebirds hunt on burrowing crabs, the endemic crab plover Dromas ardeola additionally feeds on swimming crabs with “fast and powerful claws”.

Long‐term recovery and food web response of benthic macrofauna following cessation of bottom trawling in a marine protected area

Conservation Science and Practice, Volume 7, Issue 4, April 2025.
The study is unique in covering how the benthic community has responded to a long‐term fishing closure in one of Europe's largest strictly marine protected areas. We find the recovery of species and strong links to the food web in the response to protection.

First record of the association between Lychnorhiza lucerna (Scyphozoa, Rhizostomeae) and Cyrtograpsus affinis (Decapoda, Varunidae) Primer registro de la asociación entre Lychnorhiza lucerna (Scyphozoa, Rhizostomeae) y Cyrtograpsus affinis (Decapoda, Varunidae)

Latin American Journal of Aquatic Research, 2012
We report the association between the jellyfish Lychnorhiza lucerna and the crab Cyrtograpsus affinis. Numerous examples of associations between medusae and brachyurans have been observed in the field and noted in the literature.

Fishers' interactions with endangered “rhinorays” in Karimunjawa National Park, and factors influencing willingness to engage in pro‐conservation behavior

Conservation Science and Practice, Volume 7, Issue 4, April 2025.
Abstract The “rhinorays” (giant guitarfish‐Glaucostegidae and wedgefish‐Rhinidae) are a critically endangered group of “shark‐like rays,” which have experienced steep global population declines in the past decade due to overfishing. Their slow life histories and high market value increase the risk of trade‐driven extinction and lead to trade‐offs ...
