Insect threats and conservation through the lens of global experts

While several recent studies have focused on global insect population trends, all are limited in either space or taxonomic scope. As global monitoring programs for insects are currently not implemented, inherent biases exist within most data. Expert opinion, which is often widely available, proves to be a valuable tool where hard data are limited. Our aim is to use global expert opinion to provide insights on the root causes of potential insect declines worldwide, as well as on effective conservation strategies that could mitigate insect biodiversity loss. We obtained 753 responses from 413 respondents with a wide variety of spatial and taxonomic expertise. The most relevant threats identified through the survey were agriculture and climate change, followed by pollution, while land management and land protection were recognized as the most significant conservation measures. Nevertheless, there were differences across regions and insect groups, reflecting the variability within the most diverse class of eukaryotic organisms on our planet. Lack of answers for certain biogeographic regions or taxa also reflects the need for research in less investigated settings. Our results provide a novel step toward understanding global threats and conservation measures for insects.Peer reviewe

Mourning and Longing: Media Studies learning to let go of liberal democracy

In her essay ‘Neoliberalism and the end of liberal democracy’, Wendy Brown suggests that critical political theory needs to ‘mourn liberal democracy’ in order to develop a transformative vision of ‘the good’. The problem, as Brown outlines it, is not only that – to varying extents and in different scales across democratic states – market rationality has hollowed out representative structures and processes and organizes social life but also that ‘basic principles and institutions of democracy are becoming nothing other than ideological shells’ that nevertheless legitimate neoliberal governmentality. Brown’s concept of mourning has implications for Media Studies’ constitutive focus on publicness and political participation within the democratic nation-state. This article considers Brown’s critique in relation to the tendency in Media Studies to admit the unachievable idealism of certain ideas – particularly in relation to the public sphere and pluralism – while continuing to use them as guiding normative standards and values. The article questions how such normative ideals can provide guidance where not only the political and institutional imaginary that underpins them has changed, perhaps irrevocably, but where the continued flagging of these ideas may be implicated in the kind of ideological camouflage Brown identifies

Bioindicator Thais carinifera (mollusca, gastropoda): imposex response and consequences along the Pakistan coast during the period from 1993 to 2012

Abstract Endocrine mediated "imposex" phenomenon was investigated and recorded in the muricoid gastropod species Thais carinifera during the two decades from 1993 to 2012 at three (3) sites out of six (6) localities investigated along the Sindh and Balochistan coast, Pakistan. The VDS stages 1 to 4 were apparent in Thais carinifera. The intensity of imposex has remained comparatively low in the populations of harbours in close proximity to port Mohammad Bin-Qasim, namely; Old Korangi Fish Harbour (OKFH) and New Korangi Fish Harbour (NKFH) where shipping activities are sporadic as compared to those in Manora Channel and the adjoining Karachi Port area where intensive shipping activity is rather frequent. Target species found to be good bioindicators have shown a marked decrease over the prolonged study period. Investigations show that this decrease is solely due to globally imposed effective bans on tributyltin (TBT) based antifouling paints over the past decade
