Water loss through evaporative cooling due to heat stress is substantial. We measured water flux and field metabolic rates (FMR) of Cape gannet chicks and adults to determine if gannets developed water saving strategies. The water economy index (WEI, g kJ−1) decreased with chick age according to the model WEI = 0.676 – 0.272 × log10(t), indicating that water efficiency increased with age. At fledging, the WEI of chicks was at the level expected of adult desert birds. Desert birds maintain a low WEI by also having a low FMR, whereas Cape gannet chicks have FMR comparable to other seabird species’ nestling requirements. We propose that maintaining low WEI is adaptive for Cape gannets because (1) chicks need to balance water loss through evaporative cooling, (2) fledglings need to overcome a period of up to a week when they cannot ingest any water and (3) adults spend extended periods in the breeding colony during which water can become a limiting factor. Understanding the physiological mechanism of maintaining low WEI will become increasingly important with future rising temperatures.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"13 1","pages":"30 - 43"},"PeriodicalIF":1.0,"publicationDate":"2018-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89896737","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}

However, little information is available on their toxicity on crustaceans. We utilized imagoes of Echinogammarus tacapensis to elucidate the effects of sublethal concentrations of permethrin. The LC50 (48, 72, and 96 h) was assessed considering several pesticide concentrations (ranging between 0.5 and 100 ng L−1) using the Regtox package and were found to be 13.88, 8.974, and 4.259 ng L−1, respectively. The biomarkers’ response was analyzed using animals exposed to 0.35, 0.7, and 1.4 ng/L of permethrin for 4 days. The catalase activity was significantly induced after 48 h of exposure to the three permethrin concentrations. Additionally, the glutathione S-transferase activity was increased in a concentration-dependent manner. However, exposed to C1 (0.35 ng L−1), the superoxide dismutase (SOD) activity showed no significant change compared to control values. The hydrogen peroxide (H2O2) rate was found to be similar to the SOD variation. Our findings suggest that permethrin poses a potential threat to freshwater amphipods and thus, the test species can be a useful tool for pesticide toxicity biomonitoring due to their small size, easy husbandry, short life cycle, and high fecundity.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"24 1","pages":"57 - 66"},"PeriodicalIF":1.0,"publicationDate":"2018-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82502393","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}

This study investigated whether relocating bleached Platygyra sinensis colonies was a viable measure to accelerate their recovery. During a mild bleaching event in 2014, eight bleached colonies of P. sinensis were relocated from an affected reef at Sultan Shoal, Singapore, to a reef at Kusu that was less impacted. Another eight colonies at Sultan Shoal were tagged as controls. After five months, 88% of relocated bleached colonies at Kusu showed full recovery whereas only 25% of the control bleached colonies at Sultan Shoal had recovered. The differential coral recovery among the two sites was most likely due to lower seawater temperatures and faster water flow at Kusu, which helped to mitigate the effects of thermal stress on the bleached corals. This relocation study demonstrated that relocating bleached P. sinensis to sites with more favourable environmental conditions is a viable approach to reduce bleaching impacts for this species.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"74 5 1","pages":"375 - 385"},"PeriodicalIF":1.0,"publicationDate":"2017-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73720068","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}

Thus, the aims of the present study were to investigate variation in thermal tolerance and its relationship with individual metabolism in juvenile qingbo (Spinibarbus sinensis). To fulfill our goal, we first measured the resting metabolic rate (RMR), maximum metabolic rate (MMR), metabolic scope (MS, MMR–RMR) and excess post-exercise oxygen consumption (EPOC) of 40 fish at 25 °C. We then measured the critical thermal minimum (CTmin), lethal thermal minimum (LTmin), critical thermal maximum (CTmax), and lethal thermal maximum (LTmax) of 20 fish. Both MMR and MS were positively correlated with the metabolic recovery rate (MRR) (p = 0.001), indicating that high aerobic metabolic performance individuals possessed an advantage for the recovery of anaerobic metabolism. However, the negative correlation between EPOC and MRR (p = 0.017) indicated a slow recovery of the metabolism of high anaerobic metabolic capacity individuals. The RMR was positively correlated with CTmin and LTmin, whereas all of the metabolic rate parameters (RMR, MMR, and MS) were negatively correlated with CTmax and LTmax (p < 0.05), indicating that high aerobic metabolic performance individuals have a weakened thermal tolerance. These results suggested that there is a trade-off between aerobic metabolic performance and thermal tolerance.","PeriodicalId":18210,"journal":{"name":"Marine and Freshwater Behaviour and Physiology","volume":"1 1","pages":"359 - 373"},"PeriodicalIF":1.0,"publicationDate":"2017-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83085850","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}
