The Philippines is a biodiversity hotspot with rich variety of terrestrial vertebrate species, many which are endemic and under threat from environmental changes unsustainable activities. Effective conservation action urgently needed; however, progress hampered by persistent knowledge shortfalls uneven research efforts. In this study, we assessed the extinction risks, threats, gaps 1,258 Philippine species. We found that at least 15%–23% species risk extinction, particularly amphibians mammals, primarily driven habitat loss overexploitation. However, reptiles remain markedly underrepresented in their true status likely underestimated. Our findings highlight historical biases continue to perpetuate inequities, leaving vulnerable data-deficient areas overlooked. Filling these balanced investment, expanded monitoring, better data sharing crucial for informed conservation. recommend using integrative tools remote sensing tackle major Philippines. Integrating collaboration, citizen science, targeted surveys, genetic can address gaps. study offers strategic framework guiding national priorities safeguarding country’s rapidly vanishing wildlife heritage, emphasizing that, without action, risks losing its unique biodiversity.

A framework to quantify the vulnerability of insular biota to global changes

Peer Community Journal, Год журнала: 2025, Номер 5

The majority of vulnerability assessments biodiversity to global changes have so far been applied to, and designed for, mainland systems, overlooking islands. However, islands harbour unique are epicentres ongoing extinctions. We thus introduce a specific framework for quantifying the terrestrial insular biota multiple threats. This uses markers exposure, sensitivity, adaptive capacity account characteristics island biodiversity. Our assessment involves five steps: (1) defining scope assessment, (2) selecting most appropriate markers, (3) computing metric, (4) evaluating uncertainties, (5) providing recommendations conservation. development this tailored systems is part larger initiative meet international policy targets that better integrate threats dimensions. discuss need urgency applying guide evidence-based decisions conservation biodiversity, increased attention at science-policy interface.

Evolutionarily Distinct Species and Their Partners Have Fewer Links in Ecological Networks

Global Ecology and Biogeography, Год журнала: 2025, Номер 34(6)

Опубликована: Май 30, 2025

ABSTRACT Aim Ecological networks describe the complex set of interconnections among species and their environment, network structure can inform stability, resilience, functioning ecosystems. Increasing attention is being paid to mechanisms that determine interactions. Phylogeny has informed our understanding connections within networks, mostly by describing strength phylogenetic conservation Here, we examine how position a relates its functional network, testing relationship between topologies. Location Global. Time Period Early 20th century present. Major Taxa Studied Birds plants. Methods We used large dataset frugivore interactions calculate degree focal (degree) partners they interact with (partner degree) bird plant phylogenies local evolutionary distinctiveness (ED), measure calculated on community‐level phylogeny. then fit binomial Bayesian models estimate effect species' ED partners. In avian incorporated traits from AVONET in contributions partner relative those ED. Results The both high birds plants tend have fewer than do low species, species. birds, statistical sizes are comparable or larger measured traits. Main Conclusions Our analysis illustrates relationships affect present‐day ecologies underscores unique ecological contribution outliers.

Accounting for the neglected: Invertebrate species and the 2019–2020 Australian megafires

Global Ecology and Biogeography, Год журнала: 2022, Номер 31(10), С. 2120 - 2130

Abstract Aim Invertebrates make up the vast majority of fauna species but are often overlooked in impact assessment and conservation response. The extent to which 2019–2020 Australian megafires overlapped with range vertebrate has been well documented; consequently, substantial resourcing directed towards their recovery. Here, we attempt document overlap these invertebrate species. In doing so, seek demonstrate that it is possible worthwhile assess effect a catastrophic event on large number poorly known Location Temperate subtropical Australia. Time period 2019–2020. Major taxa invertebrates. Methods We adapted published analytical pathway for distributional fire Overlaps 32,163 were determined using point records polygons. Results found 13,581 had part burnt megafires. Of these, 382 whole burnt, further 405 50–99.9% burnt. Five examples described. Main conclusions Poorly groups biodiversity can be impacted significantly by major disturbance events, such overlooked.

Continental risk assessment for understudied taxa post‐catastrophic wildfire indicates severe impacts on the Australian bee fauna

Global Change Biology, Год журнала: 2021, Номер 27(24), С. 6551 - 6567

Abstract The 2019–2020 Australian Black Summer wildfires demonstrated that single events can have widespread and catastrophic impacts on biodiversity, causing a sudden marked reduction in population size for many species. In such circumstances, there is need conservation managers to respond rapidly implement priority remedial management actions the most‐affected species help prevent extinctions. To date, responses been biased towards high‐profile taxa with substantial information bases. Here, we demonstrate sufficient data are available model extinction risk less well‐known species, which could inform much broader more effective ecological disaster responses. Using publicly collection GIS datasets, combined life‐history data, modelled from 553 native bee (33% of all described taxa). We suggest two now eligible listing as Endangered nine Vulnerable under IUCN criteria, basis fire overlap, intensity, frequency, traits: this tally far exceeds three listed threatened prior wildfire. how undertake wide‐scale assessment wildfire impact poorly understood group focus surveys recovery efforts. also provide methods script required make similar assessments other or regions.
