New technique multiplies life span in simple organisms

...ganisms in Longo's experiment showed extraordinary resilience under stress. "We hit them with oxidants, we hit them with heat," Longo said. "They are highly resistant to everything. What they're doing is basically saying, 'I cannot afford to age. I still have to generate offspring, but I don't have enough food...

Older female fish prefer imperfect male mates, study finds

...with environmental stresses and could pass on that resilience to offspring. Another explanation would be that the visual system "develops an internal prototype of an object that is based on an average of all the male fish [the females] have seen," Morris said. "Therefore, any fish they see that is closest to t...

Tiny polyps gorge themselves to survive coral bleaching

...ases globally. But Grottoli warns that Montipora's resilience doesn't diminish the threat that bleaching events hold for the world's coral reefs. While it might survive while other species may not, on a global scale it is unlikely to re-colonize areas where less-resilient species died. "Recent projections sug...

Ancient DNA provides clues to the evolution of social behavior

...ve only a couple of tools, you don't have a lot of resilience for dealing with an unexpected event.'' According to Chan, the evolution of the colonial tuco-tuco's social behavior may be linked to the population bottleneck. Because all surviving colonial tuco-tucos are closely related, it makes sense evolutiona...

Batfish to the rescue!

...hich are in decline in many areas. "Indeed, the resilience of inshore GBR reefs may be closely tied to the fate of mangroves and their suitability for batfish recruitment." Batfishes may be one of the last intact herbivore populations capable of reversing serious weed overgrowth of inshore coral reefs, he...

Adult Antarctic midges usually live only a week or two in the field and, in the laboratory, the adults lived for five to six days at the lower temperature. But adult midges exposed to the higher temperature died in l...

"These data are directly relevant to the resilience of Amazonian conservation, as they do not support the contention that all of Amazonia is a 'built landscape' and therefore a product of past human land use," Bush says.

Corals that can fight global warming may one day help fragile reefs

"Some corals show unusual resilience to the double threat [of pathogens and warming seas], and we should look to these hardy corals for clues that might enhance others," said Harvell. "Other corals are more sensitive and will not survive the continued warming trend." Yet there seems t...
