Abstract:Global biodiversity loss is a critical environmental crisis, yet the lack of spatial data on biodiversity threats has hindered conservation strategies. Theory predicts that abrupt biodiversity declines are most likely to occur when habitat availability is reduced to very low levels in the landscape (10-30%). Alternatively, recent evidence indicates that biodiversity is best conserved by minimizing human intrusion into intact and relatively unfragmented landscapes. Here we use recently available forest loss dat… Show more
“…This will increase the probability of extinction for many tree species of Sri Lankan rainforests, which have shown a high degree of niche differentiation. Our results on the association between anthropogenic disturbance and increased conservation need are in accordance with the findings of Barlow et al 63 , Betts et al 64 and Feng et al 65 .

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD).
Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD.
The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC).
Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…In line with Betts et al. (), who showed that globally forest loss in intact landscapes can degrade biodiversity disproportionately, our findings imply that substantial biodiversity declines do occur even though habitat availability did not yet fall to very low levels (less than 30%). This appears to be especially the case, when initial intrusions, such as biological invasions, coincide with the effects of habitat loss and impose an extinction filter whereby the most sensitive species (typically specialist, narrowly distributed, endemic species) are lost rapidly; leading not only to local but global biodiversity decline.…”

“…Our results show that averting the conversion of natural and semi-natural areas, those with HFP values ≥ 3, is the most effective strategy to prevent species from undergoing a high-risk transition in their conservation status when accounting for environmental and life-history traits. These results are in line with recent findings that deforestation within intact landscapes is the strongest correlate of decline in forest species 24 , opening up the path to a number of direct threat mechanisms (such as hunting, diseases spread, and invasive species). However, protecting natural and semi-natural landscapes is not sufficient to improve the status of species which are already at a high risk, some of which have little natural habitat left within their distributions and will require habitat restoration to reduce their risk of extinction.…”
