Things are not always what they seem when it comes to fish -- something scientists at the Smithsonian Institution and the Ocean Science Foundation are finding out. Using modern genetic analysis, combined with traditional examination of morphology,...
Wild rainbow trout critical to health of steelhead populations
CORVALLIS, Ore. -- Genetic research is showing that healthy steelhead runs in Pacific Northwest streams can depend heavily on the productivity of their stay-at-home counterparts, rainbow trout.
Steelhead and rainbow trout look different, grow d...
Fishy consequences of transplanting trout, salmon, whitefishes
Montreal, January 26, 2011 -- Not all trout are created equal. Those swimming up the streams of British Columbia might resemble their cousins from Quebec, yet their genetic makeup is regionally affected and has an impact on how they reproduce, ...
Mercury in Bay Area fish a legacy of California mining
ANN ARBOR, Mich.---Mercury contamination, a worldwide environmental problem, has been called "public enemy No. 1" in California's San Francisco Bay.
Mercury mining and gold recovery in the mid-1800s to late 1900s, combined with present day oil ref...
The universe’s most massive stars can form in near isolation, new...
ANN ARBOR, Mich.---New observations by University of Michigan astronomers add weight to the theory that the most massive stars in the universe could form essentially anywhere, including in near isolation; they don't need a large stellar cluster...
Female fish — and humans? — lose interest when their male...
You may think of your love for your mate as the noble emotion of a pure heart, but some primitive parts of your brain are taking a decidedly more pragmatic approach to the subject, according to Stanford biologists.
In experiments with African ci...
Research team from the Basque Country investigates species of bat that...
There are 27 species of bats identified in the Basque Country today. Twenty years ago there were hardly any records. This data reflects the fruitful work on the ecology and behavioural development of bats by the University of the Basque Country (UPV...
Discus fish parent young like mammalian mothers
Few fish are famed for their parenting skills. Most species leave their freshly hatched fry to fend for themselves, but not discus fish. Jonathan Buckley from the University of Plymouth, UK, explains that discus fish young feed on the mucus that the...
Large-scale fish farm production offsets environmental gains
VICTORIA -- Industrial-scale aquaculture production magnifies environmental degradation, according to the first global assessment of the effects of marine finfish aquaculture (e.g. salmon, cod, turbot and grouper) released today. This is true even ...
