#mites of the #Astigmata (#Acariformes) are soft-skinned. Their thin #cuticle is sensitive to #drought, which is why they avoid leaving their mostly #moist #fungus- and bacteria-rich #habitats. For the purpose of #dispersal, a modified instar, the #deutonymph, with stronger cuticle and other specific #adaptations #evolved, performing #phoresy, the transport most often via larger arthropods.

#Cities with extensive #waterways can exhibit higher levels of #urban #biodiversity; however, modified and slow-flowing #rivers and #canals can also release #methane and #carbon #dioxide, which support #globalwarming. Their importance as #flightcorridors for the urban #dispersal of #flying #animalspecies should not be overlooked. Pictured here: the #Spree River in #Berlin.

This is an interesting article (linked below) about #biodiversity and #populationdynamics of #microscopic #seafloorfauna elements, and their presumed modes of #dispersal and ability to adapt to far away #ecologically different conditions. It focuses on the nematode genus #Halalaimus.
I want to point out that even terrestrial nematodes are masters of interesting #dispersalstrategies, evolved based on their small sizes and limited distance #mobility.

🪧 2 new articles from #TheGrackleProject!

🔍 Grackles who were #trained to be more #flexible were more #exploratory after the training than untrained grackles. This indicates that the more an individual investigates a novel object, the more it can learn and adapt its #behavior accordingly

✈️ Grackles in an edge #population disperse farther than those in a more central population. This suggests that the rapid geographic range expansion of great-tailed grackles is associated with individuals differentially expressing #dispersal behaviors

🗺️ These results suggest that flexibility, exploration, and dispersal are key traits involved in this species’ rapid expansion into new areas

💪 They started as #RegisteredReports @ #PCIEcology @PeerCommunityIn years ago! After lots of hard work from many collaborators (including @DieterLukas) they are now at the #diamondOA @PeerCommunityJournal 🎉

I was talking with local birder Phil Crutchley this afternoon and I mentioned to him the sad news that I'd found dead on the roadside one of the Australasian harriers that he had banded. That female Phil had banded near his home in April 2023 and I found it hit by a car less than 3 km away in June this year.

Ah, you might think, harriers don't travel far from home. But, no. Phil told me about another harrier he had banded at his home that, only 30 days later, was sighted in the Hawkes Bay in the North Island, about 700 km away.

I guess if you're a big bird with big wings, you've got a lot of choices.

Iguanas floated one-fifth of the way around the world to colonize Fiji. Researchers find that Fiji iguanas are most closely related to the North American desert iguana — evidence of the longest known transoceanic dispersal of any land animal.

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.”

@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.”

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."

Some plants can monitor #environmental #conditions around them and release #seeds at times #optimal for #dispersal.

#Dandelion seeds close up a bit in #wet #weather and don't travel as far as in their more open, #dry weather form. New #research (Seale et al. 2022) shows that dandelions hold on to seeds in wet weather and release them more in dry weather.

Do #plants exhibit #behavior? I would argue, yes.

This leads to the next fascinating fact about Triops (and many other branchiopods): their eggs can withstand transit through the digestive tract of other animals. The presence of this feature in so many branchiopod suggests that it might be basal for the clade. If so, then what the hell was eating them and pooping out their eggs in the Devonian or before?
