对杂交三倍体泥鳅（4n♀×2n♂）的胚胎染色体进行了C带及染色体荧光原位杂交（FISH）分析，首次探讨了杂交三倍体泥鳅C带特征，为准确鉴别染色体提供依据，研究了核糖体5.8S+28S rDNA在杂交三倍体泥鳅胚胎中期染色体上的数目和位置。C带结果表明，杂交三倍体泥鳅的染色体C带包括臂端C带和着丝粒C带，没有发现臂间C带。M染色体只有1号染色体既有臂端C带又有着丝粒C带，但臂端C带均比着丝粒C带大，...

When Captain Ahab left harbour to
hunt the white whale, he did not
know exactly where to start. Cruising
the hard sea of the nineteenth-century whaling fleets, he hunted and waited, primed for
the...
Crude Oil Impairs Cardiac Excitation-Contraction Coupling in Fish
Crude Oil Cardiac Excitation Contraction Coupling Fish
2015/11/16
Crude oil is known to disrupt cardiac function in fish embryos. Large oil spills, such as the Deepwater Horizon (DWH) disaster that occurred in 2010 in the Gulf of Mexico, could severely affect fish a...
Using multivariate adaptive regression splines to predict the distributions of New Zealand’s freshwater diadromous fish
distribution environment fish fresh-water MARS
2015/8/21
Relationships between probabilities of occurrence for fifteen diadromous fish species and environmental variables characterising their habitat in fluvial waters were explored using an extensive collec...
Variation in demersal fish species richness in the oceans surrounding New Zealand:an analysis using boosted regression trees
Demersal fish Species richness Boosted regression trees Statistical model
2015/8/21
We analysed relationships between demersal fish species richness, environment and trawl characteristics using an extensive collection of trawl data from the oceans around New Zealand. Analyses were ca...
Dispersal,disturbance and the contrasting biogeographies of New Zealand’s diadromous and non-diadromous fish species
Boosted regression tree diadromy dispersal disturbance fish freshwater statistical model species ranges
2015/8/21
Aim To examine the relationship between diadromy and dispersal ability in New Zealand’s freshwater fish fauna, and how this affects the current environmental and geographic distributions of both diadr...
Transport Patterns of Tropical Reef Fish Larvae by Spin-Off Eddies in the Straits of Florida
Tropical Reef Fish Larvae Spin-Off Eddies Straits of Florida
2015/8/10
Tropical reef fishes belong to a broad phylogenetic group and, as a result, exhibit considerable diversity. Their only shared characteristic as an ecological entity is their fate as reef-associated ad...
Seasonal Variation of Pelagic Fish Catch Around Java
Seasonal Variation Pelagic Fish Catch Around Java

As part of the Japan/East Sea (JES) initiative supported by the U.S. Office of Naval Research, we conducted an observational experiment to understand the physics of the mesoscale circulation in the Ul...
Temperature Effects on Growth and Stress Physiology of Brook Trout: Implications for Climate Change Impacts on an Iconic Cold-Water Fish
growth stress heat shock protein cortisol
2015/1/4
Despite the threat of climate change, the physiological mechanisms by which temperature drives the distribution of species are unclear. Here we used chronic temperature exposures to determine that the...
Honesty and Carotenoids in a Pigmented Female Fish
antioxidants carotenoids Cichlidae coloration immunity
2014/12/18
The carotenoid tradeoff hypothesis states that diet-derived carotenoids are tradedoff among competing physiological demands, but this statement is rarely tested in ornamented females. The following di...
Invertebrate Phenology and Prey Selection of Three Sympatric Species of Salmonids; Implications for Individual Fish Growth
Invertebrate Phenology Prey Selection Three Sympatric Species Salmonids Individual Fish Growth
2014/12/12
Growth plays an important roll in the survival of individual salmonid fish. Diet inevitably plays a significant role in the determination of salmonid growth, with these diets consisting primarily of a...
The asymmetry of the underwater horizontal light field and its implications for mirror-based camouflage in silvery pelagic fish
horizontal light field silvery pelagic fish
2014/11/28
Many pelagic species, particularly teleost fish, have silvered lateral surfaces that are thought to primarily serve
as a form of camouflage. The underlying argument is that the underwater light field...
