Human activities have significantly impacted natural habitats and wildlife worldwide, particularly emphasizing repercussions for freshwater associated species. These negative impacts on fish are well known, but mammal species that regularly use dependend systems, there is an incomplete understanding. Here, we assessed the status of semi-aquatic inhabiting dependent ecosystems (hereafter referred to as mammals) evaluated impact human richness both globally by biogeographical regions. We used structural equation modeling simultaneous autoregressive models assess direct indirect effects seven anthropogenic-related variables overall richness. Specifically, examined anthropogenic disturbance threatened non-threatened species, with decreasing stable/increasing populations. Forty-three percent all classified IUCN Red List, 50% experiencing population declines. Furthermore, 48% affected domestic or international trade, while 75% face threats from geographically expanding activities.

Genome size is positively correlated with extinction risk in herbaceous angiosperms

New Phytologist, Год журнала: 2024, Номер 243(6), С. 2470 - 2485

Опубликована: Июль 30, 2024

Angiosperms with large genomes experience nuclear-, cellular-, and organism-level constraints that may limit their phenotypic plasticity ecological niche, which could increase risk of extinction. Therefore, we test the hypotheses large-genomed species are more likely to be threatened extinction than those small genomes, effect genome size varies across three selected covariates: life form, endemism, climatic zone. We collated information for a representative sample angiosperms comprising 3250 species, analyzed alongside zone variables using phylogenetic framework. Genome is positively correlated risk, pattern driven by signal in herbaceous but not woody regardless climate endemism. The influence stronger endemic relatively homogenous different climates. Beyond its indirect link via endemism climate, associated directly significantly. serve as proxy difficult-to-measure parameters resilience vulnerability angiosperms. it merits further exploration useful biological attribute understanding intrinsic augmenting plant conservation efforts.

Global Metrics for Terrestrial Biodiversity

Annual Review of Environment and Resources, Год журнала: 2024, Номер 49(1), С. 673 - 709

Опубликована: Окт. 18, 2024

Biodiversity metrics are increasingly in demand for informing government, business, and civil society decisions. However, it is not always clear to end users how these differ or what purpose they best suited. We seek answer questions using a database of 573 biodiversity-related metrics, indicators, indices, layers, which address aspects genetic diversity, species, ecosystems. provide examples indicators their uses within the state–pressure–response–benefits framework that widely used conservation science. Considering complementarity across this framework, we recommend small number considered most pertinent use decision-making by governments businesses. conclude highlighting five future directions: increasing importance national ensuring wider uptake business agreeing on minimum set government use, automating metric calculation through technology, generating sustainable funding production.

Heads up–Four Giraffa species have distinct cranial morphology

PLoS ONE, Год журнала: 2024, Номер 19(12), С. e0315043 - e0315043

Опубликована: Дек. 19, 2024

Giraffe ( Giraffa spp.) are among the most unique extant mammals in terms of anatomy, phylogeny, and ecology. However, aspects their evolution, ontogeny, taxonomy unresolved, retaining lingering questions that pivotal for conservation. We assembled largest known dataset skulls (n = 515) to investigate patterns cranial variability using 3D geometric morphometrics. The results show distinct sexual dimorphism divergent ontogenetic trajectories skull shape north clade G . camelopardalis antiquorum , c peralta reticulata ) south giraffa angolensis g tippelskirchi t thornicrofti which was further supported statistically. Discriminant functions found statistically significant differences between all four species, some cases also subspecies same species. Our morphometric analysis shows genetically spp. have morphologies, largely addressable features display (ossicones). highlight importance focusing future giraffe conservation efforts on each taxon maintain characteristics biodiversity wild.

Prioritising natural heritage: Evaluating distribution, threats, and conservation needs of species recovery targets in Vietnam

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Янв. 6, 2025

Our study addresses the urgent need to identify and prioritise threatened species in Vietnam for conservation recovery. With a focus on Vulnerable, Endangered, Critically Endangered with high levels of endemicity (> 50% their global range occurs Vietnam), we conducted comprehensive analysis key prioritisation, IUCN Green Status Assessment, recovery strategies within Vietnamese landscape. By integrating data provincial hotspots protected areas as sites, established robust framework assess richness, threats, needs. We identified 203 across 12 taxonomic classes, establishing viable list wildlife priorities. Habitat loss exploitation were primary threats species; alarmingly, only 38% these had > areas, emphasizing needs that extend beyond current area boundaries. findings hold significance guiding strategies, resource allocation, policy decisions relation Vietnam's National Biodiversity Strategy Action Plan (NBSAP) inform measurable prioritisation goals under Target 4 Convention Biological Diversity (CBD). pinpointing regions require immediate attention, our provides essential guidance policymakers, conservationists, managers/donors. Acting insights will enhance effectiveness efforts ensure long-term sustainability vital natural heritage.
