Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction alien species. Existing global databases species' threat status or population time series are dominated by charismatic The collation datasets with broad taxonomic biogeographic extents, that support computation a range biodiversity indicators, is necessary enable better understanding historical declines project - avert future declines. We...
Abstract The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems ( https://www.nhm.ac.uk/our-science/our-work/biodiversity/predicts.html )—has collated from published studies a large, reasonably representative database comparable samples biodiversity multiple sites that differ in the nature or intensity human impacts relating to land use. We have used this evidence base develop global and regional statistical models how local responds these measures....
Abstract Logged and disturbed forests are often viewed as degraded depauperate environments compared with primary forest. However, they dynamic ecosystems 1 that provide refugia for large amounts of biodiversity 2,3 , so we cannot afford to underestimate their conservation value 4 . Here present empirically defined thresholds categorizing the logged forests, using one most comprehensive assessments taxon responses habitat degradation in any tropical forest environment. We analysed impact...
Abstract Agricultural expansion is the primary driver of ecological degradation across tropics. Set-asides—uncultivated parts agricultural landscapes, often on steep slopes and alongside rivers—may alleviate environmental impacts but can reduce area cultivated. Here we model an approach to configuring set-asides aimed at optimizing outcomes (biodiversity, above-ground carbon storage nutrient cycling) without reducing net cultivation area. We compare in oil palm landscape where all...
The impacts of degradation and deforestation on tropical forests are poorly understood, particularly at landscape scales. We present an extensive ecosystem analysis the logging conversion forest to oil palm from a large-scale study in Borneo, synthesizing responses 82 variables categorized into four ecological levels spanning broad suite properties: (i) structure environment, (ii) species traits, (iii) biodiversity, (iv) functions. Responses were highly heterogeneous often complex nonlinear....
Current climate change is disrupting biotic interactions and eroding biodiversity worldwide. However, species sensitive to aridity, high temperatures, variability might find shelter in microclimatic refuges, such as leaf rolls built by arthropods. To explore how the importance of shelters for terrestrial arthropods changes with latitude, elevation, climate, we conducted a distributed experiment comparing versus control leaves across 52 sites along an 11,790 km latitudinal gradient. We then...
A dataset of 3,250,404 measurements, collated from 26,114 sampling locations in 94 countries and representing 47,044 species.

Habitat degradation is pervasive across the tropics and particularly acute in Southeast Asia, with major implications for biodiversity. Much research has addressed impact of on species diversity; however, little known about how ecological interactions are altered, including those that constitute important ecosystem functions such as consumption herbivores. To examine rainforest alters trophic interaction networks, we applied DNA metabarcoding to construct networks linking forest-dwelling...
Abstract The functional stability of ecosystems depends greatly on interspecific differences in responses to environmental perturbation. However, perturbation are not necessarily invariant among populations the same species, so intraspecific variation might also contribute. Such inter-population response diversity has recently been shown occur spatially across species ranges, but we lack estimates extent which individual an entire community have that vary through time. We assess this using...
In Southeast Asia, biodiversity-rich forests are being extensively logged and converted to oil palm monocultures. Although the impacts of these changes on biodiversity largely well documented, we know addition samples collected in 201 little about how large-scale affect freshwater trophic ecology. We used stable isotope analyses (SIA) determine land-use relative contribution allochthonous autochthonous basal resources 19 stream food webs. also applied compound-specific SIA bulk-SIA position...
Abstract Accelerating loss and degradation of tropical forests has led to a pressing need understand the conservation value remaining forests. Whereas most studies focus on responses in community composition taxonomic richness, more sensitive habitat are likely be apparent through changes trophic complexity generalist predators. Food web theory predicts that both position niche breadth predators decrease with degradation, consequences for biotic interactions ecosystem functioning. Using...
Abstract Baited pitfall traps (BPTs) and flight intercept (FITs) are the most common methods employed for sampling dung beetle communities. These vary in their efficacy affected by factors such as bait types used dispersal abilities of different species. We present first quantitative comparison community composition, taxonomic functional diversity beetles caught human BPTs FITs Bornean tropical forests. Functional metrics were calculated based on three traits nesting method, body length,...
The construction of shelters on plants by arthropods might influence other organisms via changes in colonization, community richness, species composition, and functionality. Arthropods, including beetles, caterpillars, sawflies, spiders, wasps often interact with host the shelters, building a variety structures such as leaf ties, tents, rolls, bags; stem galls, hollowed out stems. Such constructs have both an adaptive value terms protection (i.e., serve shelters) but may also exert strong...
Abstract Habitat degradation is pervasive across the tropics and particularly acute in Southeast Asia, with major implications for biodiversity. Much research has addressed impact of on species diversity; however, little known about how ecological interactions are altered, including those that constitute important ecosystem functions such as pest consumption. We examined rainforest alters trophic interaction networks linking insectivorous bats their prey. used DNA metabarcoding to study...
Abstract Objectives To test the feasibility of a randomised controlled trial (RCT) aspirin and/or vitamin D3 in active surveillance (AS) low/favourable intermediate risk prostate cancer (PCa) patients with Prolaris® testing. Patients and Methods Newly‐diagnosed PCa (PSA ≤ 15 ng/ml, International Society Urological Pathology (ISUP) Grade Group ≤2, maximum biopsy core length <10 mm, clinical stage ≤cT2c) were recruited into multi‐centre randomised, double‐blind, placebo‐controlled study...
Abstract Agricultural expansion across the tropics is primary driver of biodiversity declines and ecosystem service degradation. However, efforts to mitigate these negative impacts may reduce commodity production. We quantify trade-offs between oil palm cultivation ecological outcomes (biodiversity, above-ground carbon storage dung nutrient cycling) different potential set-aside (uncultivated areas in agricultural landscapes) strategies. show that all configurations yield substantial gains...

Logging activities degrade forest habitats across large areas of the tropics, but impacts on trophic interactions that underpin ecosystems are poorly understood. DNA metabarcoding provides an invaluable tool to investigate such interactions, allowing analysis at a far greater scale and resolution than has previously been possible. We analysed diet insectivorous fawn leaf-nosed bat Hipposideros cervinus disturbance gradient in Borneo, using dataset ecological from unprecedented number...
