Published: Dec. 1, 2023

Citizen science and spatial ecology analyses can inform species distributions, habitat preferences, threats in elusive endangered such as seahorses. Through a dedicated citizen survey submitted to the Italian diving centers, we collected 115 presence records of two seahorses occurring along coasts: Hippocampus hippocampus H. guttulatus. From this dataset, used 85 seahorse valitaded identify ecological features these poorly known quantify effects human activities on their suitability through geographic information systems distribution modelling. Our results indicated continuous suitable area for both coasts, with single major gap central Adriatic Sea (Emilia-Romagna Marche regions). They co-occurred most range, particularly southern Tyrrhenian niches resulted be significantly similar, although not equivalent. The least-cost paths were concentrated Italy (Apulia, Calabria, Sicily), suggesting that more data is needed improve resolution available information, especially northern Italy. Human influenced 35% 41% guttulatus, respectively, while only 25% 30% potential are protected by Italy's existing conservation system, accordance global average In particular, represents critical where occurrence lower anthropic impact higher. Considering all regions, fishing effort main activity impacting species. These findings will support implementation efficient actions. We encourage application interaction facilitate assessment sustainable management organisms.

Abstract The Fritillaria species ranked as a well-known traditional medicine in China and has become rare due to excessive harvesting. To find reasonable strategy for conservation cultivation, identification of new ecological distribution together with prediction those responses climate change are necessary. In terms current occurrence records bioclimatic variables, the suitable habitats delavayi , taipaiensis wabuensis were predicted. comparison Maxent GARP, Biomod2 obtained best AUC, KAPPA TSS values larger than 0.926 was chosen construct model. Temperature seasonality indicated put greatest influence on while isothermality most importance . areas three distributed south-west China, accounting approximately 17.72%, 23.06% 20.60% China's total area, respectively. During 2021–2100 period, F. reached maximum under SSP585 scenario, that SSP126 scenario. high niche overlap among showed correlation chemical composition ( P ≤ 0.05), no observed between DNA barcodes, indicating spatial had major species. Finally, acquisition species-specific would contribute decrease habitat competition, future cultivation

Species distribution modelling and landscape connectivity as tools to inform management and conservation for the critically endangered Himalayan brown bear (Ursus arctos isabellinus) in the Deosai National Park, Pakistan

Frontiers in Ecology and Evolution, Journal Year: 2025, Volume and Issue: 12

Published: Jan. 13, 2025

The main cause of the global threat to large carnivore populations living in high-altitude areas is human pressure. Himalayan brown bear ( Ursus arctos isabellinus , hereafter bear) listed as a critically endangered species, and it dominates higher altitudes North Western landscapes. Here, we used species distribution modelling landscape connectivity find bears’ suitable habitats corridors Deosai National Park (DNP) surrounding areas. Species models detected bear’s habitat 1,125 km 2 which ca. 73% was covered by DNP. most crucial predictors determining were elevation—particularly if between 3,500 4,500 meters above sea level—as well distance from rivers, cattle, DNP borders. We discovered robust among presence points core study area, particularly within boundaries, using electrical circuit theory models. Landscape values indeed low some outside close confines. Based on our findings, imperative protect that allow bears migrate patches, beyond park’s improve conservation.

Global scale high-resolution habitat suitability modeling of avifauna providing pollination service (sunbirds, Nectariniidae)

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 19, 2025

Avian species provide important ecosystem services such as nutrient cycling, seed dispersal, meat provision, pest control, scavenging, and pollination. Currently, the populations of avian pollinators are declining due to climate change human impact, it is crucial identify species-rich areas for their conservation. Sunbirds (Nectariniidae) vertebrate with a wide distribution that include Africa, Asia Australasia. Here, we assembled records sunbird applied maximum entropy approach model habitat suitability in world. We also quantified sunbirds composition similarity among terrestrial biomes. found reached peak Southeast Asia, western central parts African continent. Sunbird richness was highest Tropical Subtropical Moist Broadleaf Forests biome. Solar Radiation Index (SRI), precipitation warmest quarter, footprint index were most predictors global suitability. Geographic regions identified have high priority conservation this unique group ecological they provide.

In order to effectively conserve a species and manage its population, it is critical understand the impact of climate change on habitat quality connectivity. The sika deer (Cervus nippon) ungulate endemic East Asia listed as Category I State Key Protected Wild Animals under Chinese law. C. nippon population was established in Shennongjia area 30 years ago, there an urgent need analyse environmental quality. this study, we compared suitable habitats connectivity by utilizing ecological niche model that integrated set factors combined with cost-distance approach for both present time well future. most encouraging findings were may be obviously enlarged improved change. limited at present; however, possible total number patches can increase twenty- thirty-fold quadruple sextuple, respectively, future (2050–2070).

Climate change has severely impacted many species, causing rapid declines or extinctions within their essential ecological niches. This deterioration is expected to worsen, particularly in remote high-altitude regions like the Himalayas, which are home diverse flora and fauna, including mountainous ungulates. Unfortunately, of these species lack adaptive strategies cope with novel climatic conditions. The Red Goral (Naemorhedus baileyi) a cliff-dwelling classified as “Vulnerable” by IUCN due its small population restricted range extent. most all goral residing temperate mountains northeastern India, northern Myanmar, China. Given population, this highly threatened climate habitat disruptions, making mapping modeling crucial for effective conservation. study employs an ensemble approach (BRT, GLM, MARS, MaxEnt) distribution assess distribution, suitability, connectivity addressing critical gaps understanding. findings reveal deeply concerning trends, model identified only 21,363 km2 (13.01%) total extent suitable under current limited alarming, it leaves very little refuge thrive. Furthermore, situation compounded fact that around 22.29% falls protected areas (PAs), further constraining species’ ability survive landscape. future projections paint even degraded scenarios, predicted decline over 34% excessive fragmentation In addition, present identifies precipitation seasonality elevation primary contributing predictors species. nine designated transboundary PAs among them highlight role supporting survival time.
