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 cyclostomus), in the isolated reef system of the Chagos archipelago. Observations of such hunting associations are rare, and no similar observations have been recorded for this region. The remoteness of this study site may provide some explanation for these multiple sightings, allowing natural behaviours to occur undisturbed. However, given no previous sightings of such behaviour, the limitation of available food resources following two recent mass coral mortality episodes, may have necessitated the formation of these rare/novel hunting interactions. Intensified prey scarcity and increasingly degraded habitat structure following more frequent disturbance events may therefore lead to such indirect environmentally mediated behavioural responses becoming increasingly prevalent in reef-dwelling species.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"30 1","pages":"35 - 42"},"PeriodicalIF":1.0,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73709936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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; and one immature male) were monitored with acoustic telemetry in a marine protected area (Portugal). The mature female remained present in the study area throughout the whole monitoring period (20 months). Residency analyses revealed this specimen spent more than 70% of the time within this coastal marine park. The immature female and the immature male were only detected during three and four months, respectively. Whether the uncovered movement patterns are common within the population remains unclear, but the present study provides useful information to better plan future research on the movement ecology of a rather unstudied species.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"43 1","pages":"283 - 299"},"PeriodicalIF":1.0,"publicationDate":"2019-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88054793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 reflect natural scenarios. We collected fish and water samples weekly in Broadkill River, Delaware, USA. We used field-collected water in colorimetric assays to determine the concentration of sGAG-equivalent molecules and in behavioral assays with a zooplankton model, brine shrimp (Artemia spp.) nauplii, which only descend in response to downwelling light after fish odor exposure. Fish quantity was positively related to sGAG-equivalents and zooplankton photosensitivity, indicated by descent responses at lower light levels and across a broad intensity range. Our results support that fish odor concentrations used in previous laboratory assays are consistent with levels found in an estuary.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"52 1","pages":"265 - 282"},"PeriodicalIF":1.0,"publicationDate":"2019-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81720592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spermatogenic activity was at its peak during June evinced from large fully extended acini with full package of mature spermatozoa and low during September–February with decreased acinar dimensions, pycnotic germ cells and residual sperms. Seasonal cyclicity was also observed in the thickness of epithelium, muscle layer, diameter of lumen and the amount of luminal contents of the vas deferens. In June, the anterior and middle vas deferenswere filled with secretions and spermatophores.By September, ruptured spermatophores with freely dispersed pycnotic spermatozoa were perceptible in the anterior and middle vas deferens and lysed spermatophoric debris in posterior vas deferens.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"93 1","pages":"217 - 240"},"PeriodicalIF":1.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74958850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fish were randomly distributed into six groups and administered with NP (10, 50 and 100 μg g-1 week-1 BW) and a single dose of 17-β estradiol (E2; 2 μg g-1 week-1 BW, positive control). The solvent controls received ethanol and coconut oil as a vehicle, while the controls were not injected. Red blood cells (RBCs) count, hematocrit (Hct), hemoglobin (Hb), white blood cells (WBCs), and lymphocytes demonstrated a NP dose-dependent decrease, whereas mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), monocytes, and neutrophils showed an increasing trend in both male and female fish 21 days post-treatment. Also, RBCs, Hb, MCHC, WBCs, and lymphocytes were significantly reduced (p<0.05) in E2 treated fish. Lysozyme, complement components (C3 and C4) and immunoglobulin M (IgM) were increased in fish sera subjected to 10 and 50 μg g-1 NP, while these decreased in groups administered with 100 μg g-1 NP and 2 μg g-1 E2. Except for C4 level at 10 μg g-1 NP, no significant differences were observed in hematological and immunological parameters of male and female in each treatment. Overall, a frequent exposure to NP could lead to adverse effects on fish immune-physiological functions which may cause serious ecological threats of fish natural population sustainability.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"8 1","pages":"151 - 165"},"PeriodicalIF":1.0,"publicationDate":"2019-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89357335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
