Behavioural response of different epithelial tissues of sea cucumber (Apostichopus japonicus) to light and differential expression of the light-related gene Pax6 Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2020-03-03 Xiaolu Liu, Lin Chenggang, Lina Sun, Shilin Liu, Jingchun Sun, Hongsheng Yang
ABSTRACT In this study, we evaluated the behavioural characteristics of the epithelial tissues of sea cucumber (Apostichopus japonicus) subjected to illumination. The behavioural results indicated that the tentacles, tube feet, and spines were sensitive to light with structural changes. Among the three epithelial tissues, the tentacles were the most sensitive with the shortest reaction and recovery

The responses of prophenoloxidase and MAPK/Nrf2 pathway to cadmium stress in red swamp crayfish Procambarus clarkii Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2020-03-03 Keqiang Wei, Junxian Yang, Changxia Song
ABSTRACT The immune response is a complex network composed of various molecules, cells and signaling pathways in crustacean. Cadmium-induced immunosuppression has been widely researched, but its underlying mechanism on crayfish proPO remains to be elucidated. In this study, the relationship between proPO activity in haemolymph and the activation of p38MAPK and Nrf2 in hepatopancreas was evaluated after

Human influences on male waving behavior in the fiddler crab Leptuca pugilator Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2020-03-03 Eleanor R. DiNuzzo, Lars Anderson, Austen Walker, Haley K. Sasso, Ben Christensen, Blaine D. Griffen
ABSTRACT Fiddler crabs are numerically dominant consumers within salt marshes and understanding how their behavior is influenced by human activities can therefore shed light on the health of disturbed marsh communities. We investigated how various levels of human influence in South Carolina salt marshes alter male waving behavior in the sand fiddler crab Leptuca pugilator across 21 marsh sites. We

Multi-species co-operative hunting behaviour in a remote Indian Ocean reef system Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2020-01-02 D.T.I. Bayley, A. Rose
ABSTRACT Inter-specific hunting associations can occur across a range of marine species to facilitate prey capture through co-operative behaviour. Here we describe multiple transient cross-phyla associations between day octopus (Octopus cyanea) and three fish species, including peacock grouper (Cephalopholis argus), brown-marbled grouper (Epinephelus fuscoguttatus), and gold-saddle goatfish (Parupeneus

Effect of ivermectin® on biometric characteristics and organ biomarkers of African catfish Clarias gariepinus Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2020-01-02 Ursula Ugonna Odo, Ifeanyi Christian Ezeoyili, Ifeanyi Oscar Aguzie, Stanley Ndubuisi Oluah, Josephine Madu, Christopher Didigwu Nwani
ABSTRACT Ivermectin® (IVM) is one of the most widely used antiparasitic drugs in human and veterinary medicine. This study assesses the effect of IVM on biometric characteristics and organ biomarkers of African catfish, Clarias gariepinus. Fish were exposed to 0.007, 0.013 and 0.033 mg/L of IVM and the brain, gill and liver were sampled on days 1, 7, 14, 21 and after 7 – day recovery. A mixed trend

Behavioral responses of northern crayfish (Faxonius virilis) to conspecific alarm cues and predator cues from smallmouth bass (Micropterus dolomieu) Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2020-01-02 Nicole C. Ramberg-Pihl, Kerry L. Yurewicz
ABSTRACT While the ability for crayfish to detect visual and chemical cues is well documented, relatively few studies have probed the behavioral responses of crayfish to cues from key predators that they encounter in natural environments. Therefore, we examined how northern crayfish (Faxonius virilis) (Hagen 1870) responded to (1) alarm cues from conspecifics versus chemical cues from smallmouth bass

Effects of low light and high temperature on pediveligers of the fluted giant clam Tridacna squamosa Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2019-11-02 William Eckman, Kareen Vicentuan, Peter A. Todd
ABSTRACT This paper examines the responses of the fluted giant clam Tridacna squamosa pediveligers to elevated temperature and reduced light levels. In a light reduction experiment, a total of 104,000 T. squamosa pediveligers were exposed to four different levels of shading for approximately one month. The most heavily shaded treatment, at 0.4% of ambient light, had significantly lower survival than

Natural variations in estuarine fish, fish odor, and zooplankton photobehavior Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2019-11-02 Corie L. Charpentier, Christopher S. Angell, Patrick I. Duffy, Jonathan H. Cohen
ABSTRACT Fish odor induces predator avoidance behaviors in zooplankton, like vertical migration, by making zooplankton more responsive to light. Odor cues that alter behavior in marine crustacean zooplankton in the laboratory include sulfated glycosaminoglycans (sGAGs) derived from fish body mucus. Few studies quantify these cues in estuarine/marine environments or assess whether laboratory studies

Preliminary insights into the spatial ecology and movement patterns of a regionally critically endangered skate (Rostroraja alba) associated with a marine protected area Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2019-11-02 Inês Sousa, Joffrey Baeyaert, Jorge M. S. Gonçalves, Karim Erzini
ABSTRACT The implementation of spatial protection measures is currently a priority in batoid species' conservation strategies, but their spatial ecology remains largely unknown. We provide some preliminary insights into the movement patterns of the white skate (Rostroraja alba), a batoid classified as Critically Endangered in European waters. Three individuals (two females: one mature, one immature;

Presence of newborn humpback whale (Megaptera novaeangliae) calves in Gold Coast Bay, Australia Mar. Freshw. Behav. Physiol. (IF 1.0) Pub Date : 2019-09-03 L Torre-Williams, E. Martinez, J.O. Meynecke, J. Reinke, K.A. Stockin
ABSTRACT The majority of humpback whales (Megaptera novaeangliae) undertake an annual migration from high latitude feeding grounds to tropical/subtropical breeding grounds. Suitable calving habitat for this species includes warm (typically 19°C to 28°C), shallow, sheltered waters in tropical and subtropical waters. Here, we investigated occurrence of calving beyond the primary recognised breeding grounds
