Climatic variables are important conditions for plant growth, development and reproduction. Citrus medica L. var. sarcodactylis Swingle (Rutaceae: ) is one of the traditional bulk Chinese medicinal materials in China with effects bacteriostasis, anti-inflammatory, anti-oxidation, anti-cancer cells, regulating immun. Analyzing impact climate change on geographical distribution C . can provide strong support its production layout agricultural zoning. In our paper, MaxEnt ArcGIS were applied to simulate suitable areas from perspectives bioclimate, soil, topographic factors human activities, future scenarios generated by global models (GCMs) selected predict 2050s 2090s.

Assessing landscape suitability and connectivity for effective conservation of two semi‐desert ungulates in Iran

Conservation Science and Practice, Год журнала: 2023, Номер 5(12)

Опубликована: Ноя. 6, 2023

Abstract Conservation outside conservation areas (CAs) is more challenging due to increased exposure human‐induced disturbances. Therefore, it important identify and designate new CAs that can protect core wildlife habitat patches, as well key linkages promote connectivity. We performed this study prioritize patches corridors for two semi‐desert sympatric gazelles in Iran (i.e., goitered gazelle Gazella subgutturosa jebeer G. bennettii ) order propose the expansion of existing CAs. used an ensemble distribution modeling approach based on three algorithms (random forest, maximum entropy, generalized boosting models) suitability assessment a combination resistant kernel factorial least‐cost path analysis connectivity modeling. Our results revealed distance CAs, elevation, annual mean temperature were most influential variables predicting species. identified 12 six gazelle, respectively with minimum area 210 km 2 . Core mainly occurred north central basin high priority both protected up half one‐third gazelle. Due disturbances (e.g., vehicle collisions poaching) necessary increase regular monitoring establish gazelles. findings highlight opportunities designating promoting by limiting road impacts.

Energy‐based corridor identification for mammals between protected areas in Iran

Ecology and Evolution, Год журнала: 2024, Номер 14(6)

Опубликована: Июнь 1, 2024

Body mass plays a crucial role in determining the mass-specific energy expenditure during terrestrial locomotion across diverse animal taxa, affecting patterns. The landscape concept offers framework to explore relationship between characteristics and expenditure, enhancing our understanding of movement. Although approach solely considers topographic obstacles faced by animals, its suitability compared previous methods for constructing resistance maps delineating corridors has not been comprehensively examined. In this study, we utilized enerscape R package generate kilocalories (kcal) incorporating digital elevation models (DEMs) body size data (kg). We assigned sizes ranging from 0.5 100 kg encompass wide range small large mammals Iran, adjusting maximum dispersal distances accordingly 50 200 km. By analyzing these scenarios, produced four each size. Next, identified potential protected areas Iran using Linkage Mapper toolkit examined barriers pinch-points along paths. Our study revealed significant findings regarding shared Iran's landscape. Despite their differing requirements, many were found be both mammal species. For example, 206 weighing 500 g, which also recognized as least-cost paths mammals. Thus, embracing comprehensive method map creation, one that incorporates species-specific traits human infrastructure becomes imperative accurately identifying consequently pinpointing pinch points barriers.

The effect of ranger patrols on the sighting of large mammals by local herders in northern Iran

Ranger patrols are essential for biodiversity conservation, particularly in protected areas where they help mitigate poaching of large mammals. Effective reduce and support higher population densities This study investigates the impact ranger on mammal sightings Central Alborz Protected Area (CAPA), northern Iran, a crucial wildlife corridor with UNESCO-listed Hyrcanian forests high-altitude grasslands. CAPA also supports livestock grazing over 200 villages, making it key area studying human-wildlife interactions. Data were gathered using semi-structured questionnaires from local herders, whose observations provide valuable insights into presence effectiveness patrols. The was divided 5 × km grid cells to ensure uniform data collection. Results show that decrease increasing distance active, semi-active, seasonal stations. trend is likely due reduced patrol coverage, which increases risks. Although factors such as habitat preferences human disturbances may contribute. Inactive stations appear have lost effectiveness, because lack regular patrols, warrants further investigation. These findings emphasize critical role consistent efforts reducing maintaining populations this ecologically important region.

Comparing drivers and protection of core habitat and connectivity for two sympatric desert carnivores

Desertification alters wildlife distribution by reducing vegetation and water resources that are associated with habitat availability quality. Therefore, in anticipation of these impacts from desertification, it is particularly important to understand compare drivers connectivity change for different species order identify those have the highest conservation concerns needs. Many Iran expected experience substantial changes their as two-thirds country show a high potential desertification. Among species, Rüppell's fox (Vulpes rueppellii) sand cat (Felis margarita) two least known occur sympatrically desert semi-desert ecosystems. Here, we assessed baseline conditions, environmental factors affect conditions species. We found cat's was spatially patchy fragmented, whereas more expansive connected. Although share some same area, our models contrasting influence habitat. For example, suitable relatively warmer, smoother terrain, closer villages. Whereas, fox's cooler, rougher at greater distances away Both occurred areas (i.e., NDVI model) less precipitation. The response temperature suggests sympatric might respond differently warming climate. overlap corridor paths core habitats Conservation Areas (CAs) small. At 75% all predicted corridors remain unprotected both Further, most severely bisected roads. Our findings highlight opportunities designating new promoting limiting road impacts.

Oligochaetes are the most abundant benthic taxa in aquatic ecosystems that play an important role food webs. The present study aims to assess diversity and origin of Eiseniella tetraedra as a non-native species Lar National Park Iran also its response current future climate change. To this, we obtained specimen from rivers sequenced mitochondrial gene Cytochrome Oxidase subunit I (COI) combined them with 117 sequences Jajroud Karaj native regions GenBank (NCBI). We run Species Distribution Modelings (SDMs) using ensemble model approach was estimated according two Shared Socio-economic Pathways (SSPs): 126 585 MRI-ESM2 based on CMIP6. According results, all samples examined originated Spanish rivers, no unique haplotype found Park. Moreover, results show high can positively affect success this different freshwater. Also, SDMs depict change would remarkably distribution E. it verifies invasion power Iran's freshwater over time.
