Often, these disturbances can disrupt crucial environmental cues vital for survival and reproduction. This study aimed to assess the impact of altering human presence on hawksbill turtle (<em>Eretmochelys imbricata</em>) nesting beaches through closures and re-openings. By conducting nocturnal patrols, monitoring personnel quantified clutch counts on each nesting site. Different stretches of nesting coastline experienced various levels of public accessibility. Between 2009 and 2023 an increasing trend in overall nesting activity was observed. Restricted access nesting sites (136 ± 13 clutches km<sup>−1</sup>) had over a 4-fold increase in clutch density compared to public beaches (33 ± 5 clutches km<sup>−1</sup>). For example, clutch counts on Fuwairit were, on average, 1.7 times higher in the years after its closure to the public. In addition, ending camping seasons before the nesting period resulted in at least a doubling of nesting activity, compared to closures during and after the nesting season had commenced. The increase in nesting activity observed in recent years suggests potential success of conservation efforts, yet challenges remain in extrapolating this to robust population estimates due to considerable knowledge gaps on hawksbills nesting ecology in the region. However, significant short-term behavioural variation in nesting activity in response to human presence highlights the importance of managing anthropogenic pressures, with closures to public access showing positive impacts on nesting activity, albeit with nuances in timing. This study provides one of the few empirical comparisons of hawksbill nesting activity before and after beach closures to human access, offering valuable insight into the effectiveness of site-specific conservation interventions.</div></div>","PeriodicalId":54898,"journal":{"name":"Journal for Nature Conservation","volume":"87 ","pages":"Article 127007"},"PeriodicalIF":2.2,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606027","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}

The goal is to identify sounds that could serve as potential environmental indicators. This study highlighted that within MPAs, coral cover, species richness, sound types abundance, and sound types richness were all higher. We also found that ichthyological composition varied depending on the observed coasts. The results align with studies on temperate reefs, which have shown that sound type richness is higher in protected areas. While some sound types were not suitable indicators for environmental monitoring—either because they were recorded only at a single site or on a single day, or conversely, because they were produced at all sites by generalist species—others appeared to be more useful as indicators.

This study addresses the challenge of managing invasive species in the Southern Buenos Aires Mountains (Argentina), a region characterized by its unique grassland ecosystems with limited protection. The research focuses on identifying and prioritizing invasive plant species that have not yet invaded but pose potential risks. To do this, we developed a system for ranking prevention priority (SRPP) that combines the criteria of potential impact and the difficulty of control in case of invasion. We selected 20 features related to biological features of the species, their area of origin and previous invasive history elsewhere, as well as feasibility of control. We surveyed the area around the reserve and detected 302 exotic plant species, with 63% classified as introduced or established, but not yet invading. The SRPP revealed that 24% of these species, including plants globally known for their invasiveness, such us <em>Silybum marianum</em>, <em>Melia azedarach</em>, and <em>Cynodon dactylon</em>, pose the highest prevention priority due to their significant potential impact and control difficulty. By providing a transparent, reproducible, and ecologically grounded method for assessing prevention priorities, this study offers a valuable tool for anticipating plant invasions.

It is then necessary to define three parameters: the proportion of carcasses that float, the probability of a floating carcass drifting until stranding; and finally, the proportion of beached carcasses that are discovered and reported. The proportion of floating carcasses is the most influential corrective factor in the reverse drift modelling process. The objective of this study is to provide a better estimation of this proportion following bycatch in fishing gear. The predicted drift of 455 common dolphins and harbour porpoises that were tagged and discarded by fishing vessels was calculated by a drift prediction model (MOTHY).

Bycatch in trammel nets and in midwater pair trawls resulted in a higher probability of these carcasses being recovered stranded. The predicted duration of the drift, on the other hand, had a negative effect on the number of strandings observed. The percentage of harbour porpoises that float was 27% (95% CI [12%,43%]), while it was 31% (95% CI [24%, 39%]) for common dolphins.
