Currents propel the spreading of invasive jellyfish

Fri, 25 May 2018 12:32:04 EDT ~ Twelve years ago, the comb jelly Mnemiopsis leidyi, originating from the North American East Coast, appeared in northern European waters. Based on the first comprehensive data collection on the occurrence of this invasive jellyfish in Europe, scientists have now shown that ocean currents play a key role for this successful invasion.

Imminent extinction of northern white rhinoceros motivates genetic recovery efforts

Thu, 24 May 2018 14:17:25 EDT ~ Earlier this year, the last remaining male northern white rhinoceros (NWR) died in captivity, nearly cementing the fate of this subspecies for extinction. In the wild, continuing threats of poaching, habitat destruction, and small population size have contributed to the rhinos' status as critically endangered. Yet, novel conservation efforts that make use of cryopreserved genetic material could save the NWR, and other threatened species, from extinction. Find out more...

Bold lizards of all sizes have higher mating success

Thu, 24 May 2018 14:15:50 EDT ~ Boldness correlates with the mating success, but not body size or sex, of yellow-spotted monitor lizards roaming the remote Oombulgurri floodplains of tropical Western Australia, ecologists report. Bold individuals expose themselves to much higher risk of being eaten by predators during the dangerous wet season. The researchers demonstrated quantifiable behavioral syndromes in the large lizards, with an intriguing relationship to the lizards' seasonal hunting strategies. Find out more...

Long-term study reveals one invasive insect can change a forest bird community

Wed, 23 May 2018 09:12:56 EDT ~ Eastern hemlock forests have been declining due to a non-native insect pest. A new study presents some of the best data showing how the decline of a single tree species leads to the disappearance of birds specialized to them. The data also indicate birds associated with non-hemlock habitat features are spreading into former hemlock forests. A single insect species has led to a less diverse bird community across this landscape. Find out more...

Invasive seaweed makes fish change their behavior

Tue, 22 May 2018 13:26:36 EDT ~ Researchers have found that changes in the seascape may impact the behavior of fish and could be leaving them less options for refuge and more vulnerable to predators. Find out more...

First record of large-antlered muntjac in Vietnam

Tue, 22 May 2018 12:33:27 EDT ~ In November 2017 -- under a biodiversity monitoring and assessment activity supported by the US Agency for International Development -- scientists and conservationists captured photographs of one of the rarest and most threatened mammal species of Southeast Asia, the large-antlered muntjac, in Quang Nam province, central Vietnam.

Giant invasive flatworms found in France and overseas French territories

Tue, 22 May 2018 08:21:34 EDT ~ One of the consequences of globalization is the introduction of invasive species. Giant hammerhead flatworms, or land planarians, up to 40 cm (over 1 foot) in length, are reported from France and overseas French territories. Find out more...

The chestnut gall wasp -- The threat of an invasive species with clonal reproduction

Mon, 21 May 2018 14:38:26 EDT ~ A molecular study carried out on the chestnut gall wasp, Dryocosmus kuriphilus, has revealed the absence of genetic variability in this invasive species, a chestnut-tree parasite, in Europe. This is due to the fact that the wasp's reproduction is strictly parthenogenetic, the females produce more females without having to be fertilized by a male. The high capacity of reproduction of the females, producing genetically identical daughters, give this insect a high invasive potential. Find out more...

Asian tiger mosquito on the move

Fri, 18 May 2018 10:27:34 EDT ~ Scientists have compared the ecological niches of the Asian tiger mosquito and the yellow fever mosquito, both of which transmit infectious diseases, on various continents. The invasion time span plays an important role in their expansion and the Asian tiger mosquito has not yet arrived in all regions where it would find a suitable environment. Find out more...
