Endangered spectacled flying foxes and vulnerable grey-headed flying foxes - misinformation is rife
"Tim Pearson, a wildlife ecologist who specialises in flying fox behaviour and communication, says the “double whammy” of destroying native forests while providing alternative food sources in farms and residential areas creates the potential for human-bat conflict and harassment, identified as a threat in recovery plans for endangered spectacled flying foxes and vulnerable grey-headed flying foxes."
“The Australian attitude towards wildlife has always been positive, providing it doesn’t inconvenience you...Unfortunately for flying foxes, in their case it often does. Things have been getting better, Pearson says, but flare-ups still occur when practical concerns – about noise, the animals’ impact on fruit growers, power outages or potential disease threats – are reported in breathless terms by the media. At worst they’re vilified and face a constant battle of disinformation, hate speech and are even persecuted.”

Within-season movements of male songbirds may be more about looking for ladies than tracking habitat conditions. An analysis by Luepold et al. of polyterritoriality and dispersal highlights mate searching as a unifying explanatory framework. Read now!

@PeerCommunityIn Interesting study. Connecting urban nature to the nature living around cities is important. “This should encourage urban planners to pay attention to the areas promoting dispersal movements between urban habitats (e.g.,UGS) and peri-urban habitats (e.g.,forests), rather than among urban habitats, when managing urban biodiversity.”

phys.orgA coral superhighway in the Indian OceanNew research has revealed that, despite being scattered across more than a million square kilometers, remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modeling, researchers at Oxford University have demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a "coral superhighway."

A #virus controls its own long-distance dispersal: a #plant virus directly induces a long-winged morph in male insect vectors. This regulation is mediated by a species-specific unclassified #gene, which was proven a downstream factor of the #insulin/insulin-like growth factor signaling pathway. The long-winged #insect #vectors induced by viruses in turn facilitate viral long-distant #dispersal and large-scale #epidemics

Challenging the accepted norm: new study by Behr et al. finds African Wild Dogs that disperse have lower mortality than those not dispersing. Could group living be riskier for some age classes than assumed due to limited access to resources? It's time to re-evaluate the costs of dispersal.

Magistrate fines earthmoving contractor $79k over koala deaths at Victorian bluegum plantation.
"A south west Victorian forest and earth moving business has been convicted and fined nearly $80,000 after hundreds of koalas were found in poor health or dead on a private property in 2020."
"The erection of a fence around the site prevented the koalas from escaping the heavy machinery works. He just did what he was contracted to do. He was not aware that he has any obligations … in relation to koalas or koala spotting."
