Ancient genetic markers in sockeye salmon can help manage healthier fish stocks

Thu, 25 May 2017 12:56:46 EDT ~ A recent study identifies new genetic markers in sockeye salmon that can help improve management of fish populations. Find out more...

How do blind cavefish find their way? The answer could be in their bones.

Wed, 24 May 2017 19:15:58 EDT ~ Blind cavefish typically have skulls that bend slightly to the left. A study suggests this orientation might help them find food as they navigate in a perpetual counter-clockwise direction around a cave. Find out more...

New coral reef fish species shows rare parental care behavior

Thu, 18 May 2017 14:38:55 EDT ~ The vast majority of coral reef fish produce large numbers of young that disperse into the ocean as larvae, drifting with the currents before settling down on a reef. A few reef fish, however keep their broods on the reef, protecting the young until they are big enough to fend for themselves. On a recent trip to the Philippines, researchers discovered a new species of damselfish that exhibits this unusual parental care behavior. Find out more...

Climate change refuge for corals discovered (and how we can protect it right now)

Wed, 17 May 2017 12:05:56 EDT ~ Scientists have discovered a refuge for corals where the environment protects otherwise sensitive species to the increasing severity of climate change. Find out more...

'Trojan fish': Invasive rabbitfish spread invasive species

Wed, 17 May 2017 11:16:46 EDT ~ For some time, unicellular benthic organisms from the Indo-Pacific have been spreading in the Mediterranean. An international team of scientists has now found evidence that a possible path of invasion has been in the gut of fish. Find out more...

How have European freshwater fish species changed over time?

Wed, 17 May 2017 09:05:23 EDT ~ Over time, humans have contributed to the loss of native species and have introduced non-native species throughout Europe. A new analysis shows how European freshwater fish have changed profoundly since 1840. At the continental scale, the contemporary fauna holds net 11 more species today as exotic species introduction (26 species) exceeded native species loss (15 species). But the biggest change was made by European species introduced from one area in Europe to another (77 species), often with fatal results. Find out more...

Travel distances of juvenile fish key to better conservation

Tue, 16 May 2017 11:43:02 EDT ~ Marine reserves -- sections of the ocean where fishing is prohibited -- promote coral reef sustainability by preventing overfishing and increasing fish abundance and diversity. But to be effective, they need to be sized right, and in a way that accounts for how far juvenile fish travel away from their parents after spawning. Find out more...

Fishing can lead to rapid evolutionary changes in exploited fish populations

Tue, 16 May 2017 10:48:05 EDT ~ Cohort after cohort, fishing typically removes large fish from the population and can lead to rapid evolutionary changes in exploited fish populations. Find out more...

Rise of aggressive reef predator may impede sea urchin recovery, study finds

Mon, 15 May 2017 18:04:31 EDT ~ A new study suggests that an aggressive reef competitor -- the Threespot Damselfish -- may have impeded the recovery of Caribbean long-spined sea urchin populations after a mysterious disease outbreak caused a massive die-off of these animals over three decades ago. Find out more...

More genes turned on when plants compete

Mon, 15 May 2017 12:21:47 EDT ~ Some people travel to northern California for wine. However, one plant biologist treks to the Golden State for clover. The lessons of plant diversity and competition learned from a clover patch can potentially unlock secrets on plant interactions around the globe. Find out more...
