Knowledge regarding future scenarios of tidal inundation and nest-site selection is required to design action plans with which to protect suitable habitats. The objectives of this study were to quantify the impact of high tides and their trends on the nesting of two endangered sea turtle species, <em>Eretmochelys imbricata</em> and <em>Chelonia mydas</em>, in Ecuador, and to assess their potential influence on hatching success. We measured microhabitat characteristics along seven beaches on which sea turtles nest on the mainland coast of Ecuador. The tidal data and the hatching success of 199 nests were monitored from 2013 to 2020. We observed a positive trend in future high tide occurrences, which are a key factor in explaining nest hatching success. This increase in high tide might cause a reduction in the hatching success of these endangered species of sea turtles; with the <em>E. imbricata</em> being the species most affected by this threat. Considering that these species are threatened, estimations of the potential risk of climate events on their reproductive success might contribute to management strategies, and in turn, to the conservation of their populations.</div></div>","PeriodicalId":54898,"journal":{"name":"Journal for Nature Conservation","volume":"86 ","pages":"Article 126926"},"PeriodicalIF":2.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used distribution data for 1,123 plant species and 18 environmental predictors (climate, soil and altitude) to project species response to two radiative forcing scenarios: SSP2-4.5 and SSP5-8.5 using MaxEnt. The species responses were analysed by the species range and richness in climate change scenarios compared to the current climate. In both forcing scenarios, the number of species expected to decrease their geographic ranges was twice the number expected to increase. The species range decrease varied by growth form, with averages from 4.19 % to 10.31 % in SSP2-4.5 and 11.9 % to 21.79 % in SSP5-8.5. We observed an 8 % and 41 % decrease in species richness under the SSP2-4.5 and SSP5-8.5 scenarios, respectively. Trees and herbs had the highest average species loss per area in both scenarios. The species loss was primarily observed in the southern and southeastern regions, where an increase in average annual temperature and the greatest decrease in average annual precipitation is expected.

Our findings reveal that pumas in this landscape did not consume prey in proportion to their abundance. Wild species, particularly capybaras (<em>Hydrochoerus hydrochaeris</em>) and giant anteaters (<em>Myrmecophaga tridactyla</em>), were the primary prey items. This suggests a specialized diet, potentially influenced by prey availability and accessibility. The estimated mean kill rate was 0.94 ± 0.5 prey/week, and pumas hunted every 2.8 ± 1.15 day. The mean weight of prey was 2.3 kg (range: 1–100 kg), which is lower than reported in temperate regions. Our models suggest that total time spent at a kill site was the primary predictor of predation events.

Lower prey density, human-carnivore conflict through livestock depredation, and canine distemper virus with a large domestic dog population are major threats to leopards outside the park.
