Advancing conservation breeding programs for marine invertebrates

Conservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Antibacterial and Antioxidant Characteristics of Pigments and Coelomic Fluid of Sea Urchin, Echinodermata Mathaei Species, from the Persian Gulf [PDF]

Journal of Kerman University of Medical Sciences, 2015
Background & Aims: Sea urchin immune responses are directly exposed to potentially pathogenic microorganisms and develop defence responses mainly based on immunocytes and humoral factors contained in the coelomic fluid.

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

Ecological Entomology, EarlyView.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

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

Fisheries 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

Tool Use by Four Species of Indo-Pacific Sea Urchins

Journal of Marine Science and Engineering, 2019
We compared the covering behavior of four sea urchin species, Tripneustes gratilla, Pseudoboletia maculata, Toxopneustes pileolus, and Salmacis sphaeroides found in the waters of Malapascua Island, Cebu Province and Bolinao, Panagsinan Province ...

Hybrid Sea-urchins [PDF]

Nature, 1912
IT may interest readers of NATURE to learn that this season we have been successful in crossing the two species of British sea-urchin, Echinus nuharis and E. acutus, at the Imperial College, and that we have reared the hybrid larvae through their entire developmental cycle in our tanks, and have now hybrid seaurchins creeping about.

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

The influence of physical factors on kelp and sea urchin distribution in previously and still grazed areas in the NE Atlantic.

PLoS ONE, 2014
The spatial distribution of kelp (Laminaria hyperborea) and sea urchins (Strongylocentrotus droebachiensis) in the NE Atlantic are highly related to physical factors and to temporal changes in temperature. On a large scale, we identified borders for kelp

Sensitivity of Mediterranean amphipods and sea urchins to reference toxicants

Ciencias Marinas, 2002
 Toxicity tests were performed in two amphipod species, Gammarus aequicauda and Microdeutopus gryllotalpa, and three sea urchin species, Arbacia lixula, Paracentrotus lividus and Sphaerechinus granularis.
