Much of extant tropical forest is subject to selective logging and hunting - extractive activities that potentially alter ecosystem function and species diversity. However, the collective impact of these threats, especially in the context of protected vs unprotected areas, is not fully understood. Here we assess how vocalizing biodiversity responds to logging and hunting, across the diel cycle, seasonally, and between protected and unprotected landscapes in Gabon. We compared soundscape saturation across 109 sites in national parks, Forest Stewardship Council (FSC) certified, and non-certified logging concessions. We estimated hunting pressure by quantifying gunshots and relative accessibility per site. Overall, we found that the soundscapes of FSC-certified concessions resembled national parks (selectively logged 20+ years ago) more so than non-certified concessions. We also found that never logged sites, part of a proposed community conserved area, had different soundscapes than all other categories, including national parks. Unlogged sites had higher saturation than logging concessions at dusk and dawn. Soundscapes and hunting pressure were highly variable across different concessions. We found that higher gunshot rates and recent logging were associated with lower soundscape saturation overall. Based on our findings, we recommend that (i) the very few never logged forests that remain (and are not yet protected) should be urgently withdrawn from selective logging, and (ii) FSC or other certification schemes should be promoted in Gabon, with an emphasis on sustainable hunting.</p></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S000632072400288X/pdfft?md5=9df1dc54754b85d3bbaaa6f425182443&pid=1-s2.0-S000632072400288X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141736547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hedgerow planting goals have been set across many countries in Europe and agri-environment schemes (AES) play a key role in reaching these targets. Passive acoustic monitoring using automated vocalisation identification (automated PAM), offers a valuable opportunity to assess biodiversity changes following AES implementation using simple, community-level metrics, such as vocal activity of birds and bats. To evaluate whether vocal activity could be used to indicate the effectiveness of AES following hedgerow planting in future result-based or hybrid schemes, we surveyed twenty-four hedgerows in England classified into a chrono-sequence of three age categories (New, Young, Old). We recorded 4466 h over the course of 30 days and measured bird and bat vocal activity using BirdNET for birds and Kaleidoscope for bats. Vocal activity of all birds, farmland birds, and bats were modelled with age and predictors of hedgerow, habitat, and weather conditions to assess changes occurring from hedgerow planting to maturity. We show an increase of vocal activity in Young and Old hedgerows compared to New ones and highlight elements of the surrounding landscape that should be considered when evaluating AES implementation on bird and bat communities. We found high BirdNET precision in community-level vocal activity and low precision of species-level observations, and we argue that vocal activity may be used in novel AES to link a result-based payment component to automated PAM results, incentivising biodiversity effective hedgerow planting and management by farmers and landowners.</p></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0006320724002842/pdfft?md5=68599c608889b5d56a51ba869a2c5f91&pid=1-s2.0-S0006320724002842-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141729001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Native species have evolved disturbance-adapted traits that confer resilience to natural disturbance provided disturbances operate within their historical range of variability. This resilience can erode as disturbance regimes change and begin operating outside this range. We assessed wildfire impacts during 1987–2018 on the northern spotted owl, an imperiled species with complex relationships with late and early seral forest in the Pacific Northwest, USA. We analyzed population- and individual-level wildfire impacts across the frequent-fire portion of the owl's geographic range at two spatial scales and uncovered important nuances involving wildfire risk. When comparing survival of owls on burned vs unburned territories, we detected no differences in apparent survival, and owls overwhelmingly remained on burned territories indicating no measurable population-level wildfire impacts. However, when including territory-scale fire characteristics we detected negative individual-level wildfire impacts that indicated apparent survival decreased and territory displacement increased with burn severity and extent within an owl's territory. Northern spotted owls were also more sensitive to fire effects within their core use area indicating that <em>where</em> fire burns is important for spotted owl conservation. These findings indicate nuance is required when discussing wildfire impacts to spotted owls, and that changing fire regimes in this portion of the northern spotted owl's range have not yet translated into negative population-wide impacts. However, dwindling populations and continued fire regime changes could exceed the adaptive capacity of remaining spotted owls, thereby resulting in negative population-wide impacts.</p></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141638309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

With the outbreak of the SARS-COV-2 pandemic (COVID-19), preventive health measures reduced human mobility worldwide. Using high-resolution telemetry, we assessed the influence of tourism on flight frequency and anthropogenic mortality in an endangered endemic island bird, the Canarian houbara bustard. We monitored 51 individuals equipped with GSM-GPRS loggers and accelerometer technology before, during and after the COVID-19 lockdown in Canary Islands. Our results showed a significant correlation between number of tourists and flight frequency of houbaras, which fly rarely, almost only when disturbed. During pre- and post-COVID periods, birds made a 325 % higher flight rate than during COVID confinement. When tourism declined, the number of rental vehicles on the islands also declined, and there was a decrease in houbara fatalities at overhead lines and roadkills. The fact that flights originated closer to roads and tracks than would be expected by chance supports the conclusion that many of these flights were caused by human or vehicle traffic. These results suggest that a high presence of tourists and vehicles in houbara areas was most likely a decisive factor responsible for the increase in anthropogenic houbara mortality. Our study represents a clear example of the negative effects of unsustainable tourism in a fragile and humanized island environment and urges to regulate tourism and vehicle traffic, implement corrective measures on overhead lines and roads, and establish restricted areas for outdoor recreation, especially where human-wildlife conflict involves endangered species.</p></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141638307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Bycatch rates were highly variable, precluding substitution from monitored to unmonitored fisheries to estimate bycatch totals, and total fishing effort was often unknown, which is also a prerequisite for scaling bycatch rates to estimate total birds killed. Ten, seven and one trawl fishery were known to catch of the order of 100s, 1000s and 10,000s of birds, respectively, and total bycatch from all monitored fisheries sums to ∼44,000 birds per year.

The most bycaught species were albatrosses and large petrels (many of which are threatened) in the Southern Hemisphere, and gannets in the Northern Hemisphere. The few long-term studies indicated that mitigation measures (particularly strategic offal management and bird-scaring lines) were effective at reducing bycatch rates.

Taken together, the clipping efficacy was diminished under drought likely due to the low water stress experienced by clipped grasses.

Large-scale spatial analyses like this are key to guide resources and the attention of decision-makers towards areas of significant value.

Here we use one of the largest gentoo colonies in Antarctica as a case study to explore pathways for the utilization of the mIBAs approach in the design and implementation of conservation measures in the Southern Ocean. For scientists and organizations willing to have a policy impact, there are two main routes to contribute to Antarctic Treaty System (ATS) decision-making: through Parties' National Delegations, or through Experts and Observers. We provide three main recommendations for incorporating the results of spatial prioritization analyses into the agenda of ATS governance bodies using the mIBAs approach: 1. Differentiate the potential contribution of mIBAs to spatial prioritization from the potential contribution to conservation planning, two different stages in the conservation process; 2. Use methods, criteria and data for delineating boundaries of potential conservation areas according to the stage of the conservation process that the outputs are expected to contribute to; 3.
