Making hostile spaces The dispersal of non consumers
* At an intersection of numerous car parks, retail industry and an amusement industrial complex in Coffs Harbour there is a small green space with benches and birds. People and birds rest there and have their lunch.
Some time ago the amusement & drink giant piped ongoing unpleasant, loud music over the small green island and the abundant car parks.
The intention of the outdoor speakers distributing noise pollution is/was to engage in then 'dispersal' of ‘loitering' non customers.
This loud and repetitive ‘music’ is also known as "aggressive" or "defensive" architecture. This design in mostly public spaces is intended as a form of 'organised abandonment' (Ruth Wilson Gilmore) of the poor and the unhoused.
Often the exclusionary design acoustic ('steady-state spam’) is combined with other anti homeless devices (anti-homeless spikes furniture) which function to keep members of the public out of public spaces.
With increasing inequality, that is non spending consumers, the system is increasingly employing hostile practices. Privately owned public spaces such as walkways, plazas, arcades and small parks have to ensure the safety of their customers and staff. Non-consumers have no place in this scheme.
* "Woolworths has installed outdoor speakers at its Darwin city store to play the supermarket's 'Fresh Food People' jingle on repeat in a bid to deter loitering.” >>

* "The NSW Police Force is currently running an Australian-first trial in Moree (an area with a high Indigenous population) using rooftop drones to "fight crime" in the area, controlled by people hundreds of kilometres away at Bankstown Airport." >>

#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.

#Mites of the #Histiostomatidae live in #darkness in their #ephemeral #microhabitats. The distinctive deutonymphs are the #dispersal stage, being transported by insects. #Adults, however, live freely and #communicate via complex #olfactorysignals. An important #glandularcomplex is located on the dorsal body side. I participated in a study about the #geranial-rich glandular #secretions (2012).

#Ascospores are the result of the sexual reproduction of #Ascomycota #fungi, being single celled or #septate. There are different ways of #dispersal. One option is obligatory or accidental transport via animals, such as #mites. The photos show mating mites of #Histiostoma sp. seemingly covered with 4 chambered ascospores. J. Karakehian et al. (2021) studied "Methods for observing, culturing, and studying living ascospores".

The #treeofheaven #Ailanthus #altissima is a #tree originally native to Asia. It arrived in #Europe as ornamental plant in the #18thcentury and increasingly #naturalized due to its high #adaptability to difficult #ecologicalconditions and its efficient #dispersal. #Globalwarming is further facilitating its current spread. J. Soler & J. Izquierdo (2024) highlight the modern situation of this #invasivespecies.

Logging machinery and other combustion machines are driving koalas out of their habitat at Bellingen/ Gleniffer's Tuckers Nob forests.

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.
