Fifty years of decline in Queensland's coastal sharks

Thu, 13 Dec 2018 10:13:36 EST ~ Queensland's coastal shark numbers are continuing a 50-year decline, in sharp contradiction of suggestions of 'exploding' shark populations, according to a new analysis. Researchers analyzed data from the program, which has used baited drumlines and nets since 1962 to minimize human-shark interactions, and now spans 1,760 km of the Queensland coastline.

Coral larvae use sound to find a home on the reef

Wed, 12 Dec 2018 12:18:53 EST ~ A new study is starting to unravel that mystery. Researchers found that the soundscape of a reef -- the combined sounds of all animals living nearby -- might play a major role in steering corals towards healthy reef systems and away from damaged ones.

Butterflies: Fallen through the net?

Wed, 12 Dec 2018 12:18:43 EST ~ Using long-term data from the ''Butterfly Monitoring Germany'' citizens' research project, scientists have now investigated the matter using butterflies as an example. According to the research, there are more butterfly species in Natura 2000 areas than elsewhere. However, the same decline in the numbers of species regardless whether the communities are located within or outside the protected areas. Find out more...

'Eavesdropping' on groupers' mating calls key to survival

Wed, 12 Dec 2018 09:33:23 EST ~ Many fish produce sounds for courtship and mating, navigation, and defending their territories. Scientists analyze these sounds to study their behavior such as reproduction. Since grouper spawning is brief and it takes them a long time to reach sexual maturity, they are vulnerable to overfishing. 'Eavesdropping' on them is key to their survival. Researchers have developed a novel acoustic monitoring technique to classify grouper species by their sounds or 'grouper calls,' with accuracy of about 90 percent. Find out more...

A future for red wolves may be found on Galveston Island, Texas

Tue, 11 Dec 2018 12:24:49 EST ~ Red wolves, once nearly extinct, again teeter on the abyss. New research finds red wolf ancestry in Texas -- providing opportunities for additional conservation action and difficult policy challenges. Researchers have identified red wolf ''ghost alleles'' in canid population on Galveston Island. Find out more...

Did supernovae kill off large ocean animals at dawn of Pleistocene?

Tue, 11 Dec 2018 11:29:41 EST ~ The effects of a supernova -- and possibly more than one -- on large ocean life like school-bus-sized Megalodon 2.6 million years ago are detailed in a new article. Find out more...

'Pest-controlling' bats could help save rainforests

Tue, 11 Dec 2018 09:19:26 EST ~ A new study shows that several species of bats are giving Madagascar's rice farmers a vital pest control service by feasting on plagues of insects. And this, a zoologist believes, can ease the financial pressure on farmers to turn forest into fields. Find out more...

Small and isolated habitat patches crucial to species survival

Mon, 10 Dec 2018 17:18:41 EST ~ Small, local patches of habitat could be playing a much bigger role in conserving biodiversity than you think, according to new research. Find out more...

Bioenergy crops could be as bad for biodiversity as climate change

Mon, 10 Dec 2018 16:51:06 EST ~ A large scale expansion in bioenergy crop production could be just as detrimental to biodiversity as climate change itself, according to new research. Find out more...

A glimmer of hope for the world's coral reefs

Mon, 10 Dec 2018 11:56:26 EST ~ The future of the world's coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a new study, the response of the Great Barrier Reef to extreme temperatures in 2017 was markedly different to one year earlier, following two back-to-back bouts of coral bleaching.
