Danaus genutia, commonly known as the tiger butterfly, is a visually appealing species in Danaidae family. As it not currently classified endangered, excluded from key protected lists at national and local levels, limiting focus on its population habitat status, which may result being overlooked butterfly conservation initiatives. Yunnan, characterized by high diversity, presents an ideal region for studying suitability D. support of regional biodiversity. This study employs MaxEnt ecological niche model, predictions regarding suitable distribution, trends genutia identifying primary environmental factors influencing their distribution.

Climate change has a profound impact on the phenology and growth of vegetation, which in turn influences distribution behavior animal communities, including prey species. This dynamic shift significantly affects predator survival activities. study utilizes MaxEnt model to explore how climate impacts North China leopard (Panthera pardus japonensis) Ziwuling region Gansu Province, China. As an endemic subspecies apex predator, is vital for maintaining structure function local ecosystems. Unfortunately, its population faces several threats, habitat change, interspecies competition, human encroachment, all are compounded by ongoing effects change. To assess requirement quality this species, we conducted survey area from May 2020 June 2022, utilizing 240 infrared cameras, identified 46 active sites. Using model, simulated suitability future under different scenarios based nine environmental variables. Our results indicate that leopards primarily influenced mean diurnal range (Bio2), with additional sensitivity isothermal conditions (Bio3), temperature seasonality (Bio4), maximum warmest month (Bio5), annual (Bio7). We also evaluated across three socioeconomic pathways (SSP126, SSP245, SSP585) time intervals: 2050s (2041–2060), 2070s (2061–2080), 2090s (2081–2100). The findings suggest significant decline high-suitability leopards, while areas medium low projected increase. Understanding these distributional changes will enhance our comprehension region’s biogeography inform conservation strategies aimed at mitigating

Ephedra sinica (E. sinica) holds significant economic and medicinal importance is predominantly found in arid areas. Due to the limitations of environmental variables, growth habits, human activities, production suitability areas E. have significantly decreased, especially five northwestern provinces China. In this study, 212 distribution points 40 variables were obtained project habitat under different emission scenarios future. It identified precipitation wettest month, monthly mean diurnal temperature difference, solar radiation intensity April July as primary factors affecting region. The high, medium, low region cover 103,000 km2, 376,500 486,800 km2. Under future scenarios, from 2021 2100 will decrease by 20%, with high decreasing 65% 85% particularly. With comprehensive are projected, filling gap projection China over long time period. show a trend. This research provides valuable insights into crucial factors, offering theoretical support for protection management efforts sinica.

The global focus on fostering harmonious interactions and promoting rational coexistence among wildlife species to uphold or reinstate biodiversity remains a prominent area of interest. We conducted study the sable yellow-throated marten in Taipinggou National Nature Reserve, Heilongjiang, China, using line transect method infrared camera traps from 2022 2023. then analyzed overlap their suitable habitats niches with aim gaining insight into interspecific competition between these two species. found that habitat areas for were 55.20 km2 23.28 km2, accounting 24.86% 10.48% total this study, respectively. was 15.73 28.5% 67.6% habitat, supporting our Hypothesis 1. first principal component (Dim1) niche explained 35.4% overall variability, which is mainly related environmental variables “Distance Settlements” Roads”.
