(Ill-Legal) Lust is a battle field: HIV risk, socio-sexuality and criminality

This paper examines the criminalisation of HIV infection. HIV transmission offences exist in all Australian states and territories, but the bulk of prosecutions have occurred in Victoria. This paper outlines criminal legal responses to the virus in that state with an overview of the legislation and case law. Victoria has several HIV specific and nonspecific offences which may be applied to situations of HIV infection risk. It is the HIV non-specific offences which have been successfully used to prosecute HIV infection risks. The case law outlines several instances where HIV positive bodies have been charged with offences for placing others at risk of HIV infection. These charges have been applied in several cases regardless of whether the complainants seroconvert. Those charged have been same-sex desiring men or African-born men who engaged in sex with Caucasian women. There are marked differences in the sentences which have been applied to these defendants, which are based on the sexuality of the defendant and complainant. This demonstrates the heterosexist and Eurocentric character of the performance of these laws. These offences do not operate in isolation to sociality, rather this area of law embodies many cultural panics about the Other. HIV transmission offences signal socio-legal panics about sexuality, race/ethnicity and disease, situating certain bodies at greater risk of crimino-legal punishment.This conference has been generously sponsored by the School of Social and Political Sciences and the Sydney Law School, University of Sydney, in collaboration with the School of Law, University of Western Sydne

Continental-scale patterns in diel flight timing of high-altitude migratory insects

Many insects depend on high-altitude, migratory movements during part of their life cycle. The daily timing of these migratory movements is not random, e.g. many insect species show peak migratory flight activity at dawn, noon or dusk. These insects provide essential ecosystem services such as pollination but also contribute to crop damage. Quantifying the diel timing of their migratory flight and its geographical and seasonal variation, are hence key towards effective conservation and pest management. Vertical-looking radars provide continuous and automated measurements of insect migration, but large-scale application has not been possible because of limited availability of suitable devices. Here, we quantify patterns in diel flight periodicity of migratory insects between 50 and 500 m above ground level during March-October 2021 using a network of 17 vertical-looking radars across Europe. Independent of the overall daily migratory movements and location, peak migratory movements occur around noon, during crepuscular evening and occasionally the morning. Relative daily proportions of insect migration intensity and traffic during the diel phases of crepuscular-morning, day, crepuscular-evening and night remain largely equal throughout May-September and across Europe. These findings highlight, extend, and generalize previous regional-scale findings on diel migratory insect movement patterns to the whole of temperate Europe.This article is part of the theme issue 'Towards a toolkit for global insect biodiversity monitoring'

Habitat use of urban-nesting lesser black-backed gulls during the breeding season

Increasing urbanisation is detrimental for some animal species and potentially advantageous for others. Urban-nesting populations of gulls have undergone rapid population increases worldwide, which has resulted in an increase in human-gull conflicts. In order to inform management and conservation decisions in relation to these populations, more information is needed about the behaviour of these birds in urban settings and how they utilise their environment. This study combined Global Positioning System (GPS) tracking data of 12 urban-nesting lesser black-backed gulls, Larus fuscus, with habitat and behaviour data over three breeding seasons (2016–2018). Despite the proximity of marine areas (~10 km), the birds only made significant use of terrestrial environments, spending two-thirds of their time away from the nest in suburban and urban areas, and one-third in rural green areas. The gulls utilised suburban and urban areas more as their chicks grew and appeared to use diverse foraging strategies to suit different habitats. These results indicate that the range of potential foraging areas available needs to be considered in management decisions and that urban bird populations may not use the resources they are expected to
