Measuring environmental degradation with bioindicators, landscape metrics, and remote sensing helps understand impact on biota. However, data on anthropogenic pressures such as plant exploitation, poaching and invasive species are crucial. We created an Anthropogenic Influence Index (AII) for medium and large mammals at the Atlantic Forest based on local environmental quality indicators and tested its correlation with existing indices, such as the Global Human Influence Index (GHII), landscape metrics and social-economic indicators. We found no correlation between the AII and the GHII, indicating that remote sensing-collected data may not reflect local and specific anthropogenic impacts on the environment. In addition, there was a correlation between the AII and the Human Development Index, drawing attention to the direct relationship between income, education and life expectancy and the incidence of environmental impacts. Thus, the AII appears to better capture local nuances of environmental impacts, particularly those significant for medium and large mammals, compared to other indicators such as GHII, human density, and landscape metrics.

Endemic species generally have higher risk of extinction; therefore, it is necessary to focus conservation actions on these groups. Tools such as the Red List, through its criteria (A, B, C, D and E) allow to establish extinction risk and a conservation status for the species. Liolaemus is a highly diversified genus of lizards from southern South America. In Chile, 64% of the species within this genus are endemic, and more than 25% are threatened. However, for most of Liolaemus we have little biological information. In this study, to assess whether the current insights are sufficient to establish the conservation statuses of these species and to determine the criteria on which the current conservation statuses are based, a bibliographic review of all available information was conducted for the Chilean endemic Liolaemus species. Our results show that the most-used criteria were those of distribution (B and D). However, abundance studies were poorly represented. Species with wider distributions present the highest number of studies and more restricted species are little studied. Finally, many evaluations are based on the expert’s opinion. We conclude that further current and temporal studies of abundance and distribution, key aspects of ecology to assess species, are essential to generate an adequate conservation status of the genus.

Mangrove forests are one of the most important habitats in the world and one of the most beautiful manifestations of nature. They are also among the oldest living creatures on the planet. Mangrove forests can sequester huge amounts of greenhouse gases, protect lives from floods and purify water, but in recent years they have been threatened with extinction and destruction. Studies show that in some countries, including Iran, more than 40% of mangrove forests have disappeared. This is why it is so important to protect the remaining mangroves. In this regard, the main objective of this research was to identify the determining factors for the use of mangrove forest conservation measures in Iran. This study used the theory of values, beliefs and norms (VBN) as the theoretical framework. The study used a survey questionnaire and structural equation modeling (SEM). It focused on all rural households in Minab city (southern Iran). The results showed that VBN can explain 69.4% of the variance in mangrove forest protection behavior. The results of SEM showed that the variables were egoistic value (EV), altruistic value (AV), biospheric value (BV), ecological paradigm (NEP), awareness of consequences (AC), attribution of responsibility (AR) and personal norms (PN) have a significant impact on the adoption of mangrove forest conservation behaviors. From a practical perspective, this study provides a logical rationale for using VBN in the application of forest conservation behaviors. The results of this study can help policy makers encourage rural households to adopt safe and environmentally friendly behaviors.

Northern Gayo Plateau, Sumatra, is home to at least five Sumatran endemic Ericaceae where large threats come from the expansion of agricultural-related activities and infrastructure development. Rhododendron frey-wysslingii (Ericaceae) which is a northern Gayo Plateau endemic was just recently rediscovered but many parts of its geographical ranges are under severe disturbance. In the present study, we reported results of population and conservation study of the species known only from four populations in the northern Gayo Plateau. The population of this species shows a J-shape pattern showing a good regeneration capacity in the wild. However, no population is known to occur in nationally protected areas. And, due to the narrow geographic ranges and threats from habitat loss from expansions of coffee and other agricultural area as well as the presence of roads and their associated activities, the species is proposed here as Endangered (EN) according to the IUCN Red List. Living plant for ex-situ conservation purposes was collected and maintained. Besides that, a species distribution modeling was performed and showed that there are several potential habitats of the species outside the currently known ranges where no plant has been recorded, including Mount Hulumasen, Mount Peuet Sagoe, Mount Leuser, and Mount Bendahara, from an elevation above 1000 m asl. The findings add to the importance of the northern Gayo Plateau as home to narrow endemic species. Future efforts are needed for the species that include further survey in potential but unexplored habitats and implementation of in-situ conservation involving relevant stakeholders.

Unintended continuous capture or so-called “ghost fishing”, by abandoned, lost, or otherwise discarded fishing gear produces negative environmental impact on marine life and nature conservation. The risk of ghost fishing in pots could be high due to potential self-baiting resulting from mortality of ghost fished catch. Self-baiting may increase ghost fishing by further attracting marine organisms, including cannibalistic conspecifics. However, self-baiting effect in pot fisheries is seldom investigated. Pot fisheries targeting snow crab (Chionoecetes opilio) in the Arctic have high risk of gear loss due to harsh weather conditions. This study quantifies ghost fishing efficiency by simulated self-baited snow crab pots containing dead snow crab relative to catch efficiency of actively fished baited pots. On average, self-baited pots captured 0.4% of target-sized snow crab compared to actively fished pots. These results showed that the impact on marine environment caused by ghost fishing in pots is not always increasing due to self-baiting and can vary throughout the time pots are exposed to ghost fishing.

The objective of this work was to analyze the species richness and conservation status of terrestrial mammals in Argentina in relation to protected areas and human footprint intensity using a spatially explicit metric. We calculated the conservation value per species integrating taxonomic singularity, chorology and national conservation category. We superimposed conservation values per pixel in 25 km2 grids with the protected areas of the country under different types of administration and management defined in this study and with the human footprint. Richness ranged from 1 to 93 species per pixel, and conservation values from 3 to 589 per pixel. Pixels with the highest richness and high conservation values represented 0.5 % and 18.8 % of the studied area, respectively. High pixel conservation values had 2.5 % of their area protected. The protected areas of Argentina covered 8.7 % of the total area of distribution of mammals. Areas under national management (e.g., national parks) conserved only 1.8 %, while the remainder corresponded to areas under sub-national jurisdiction (e.g., provincial reserves) and under resource management. Most taxa had less than 10 % of their range within protected areas. The high, medium and low human footprint affected 12 %, 33.2 % and 53.3 % of the studied area, respectively. The high footprint impacted on 1.2 % to 14.5 % of the distribution of the different orders of mammals, with Lagomorpha and Pilosa being the most affected. Areas of high conservation value were poorly represented in protected areas, and were impacted by a high human footprint.

Human-induced habitat transformation often leads to habitat degradation and loss, impacting suitable habitats for endangered and rare species. This study was conducted to assess suitable habitats for the endangered oriental white stork in the wetland ecosystem of northeast China, to facilitate successful species-habitat conservation. The study incorporated field surveys, literature reviews, vegetation index calculations, eDNA for assessing prey abundance and land use and land cover classification for the years 2000, 2011, and 2022. A fuzzy logic-based habitat model was developed to map suitable habitats for the oriental stork. Generalized Linear Models (GLM) and Principal Component Analysis (PCA) were used to assess the influence of various environmental variables on habitat suitability changes. Roosting locations of the oriental stork were used as reference points to evaluate the impact of environmental factors on habitat suitability. The results indicate that 20% of the area is highly suitable for the stork, 73.4% is moderately suitable, and 5.6% is less or not suitable. Habitats near lakes and rivers, with low Normalized Difference Vegetation Index (NDVI) and high Normalized Difference Water Index (NDWI), are more suitable compared to areas close to roads and built-up zones. Prey abundance, particularly fish, is a crucial determinant of oriental stork presence and survival. Marshlands, swamps, and water bodies were identified as the most suitable habitats, as they interface with lotic and lentic ecosystems providing abundant prey for the storks. Our findings emphasize the importance of ongoing efforts to protect wetland ecosystems and habitats for endangered and rare bird species. Priority should be given to habitats identified as critical roosting areas for the oriental stork.

Assessment of coastal habitat quality assessment is of great significance for sustainable coastal development. However, few attempts have been made to conduct an integrated assessment of coastal habitat quality. Consequently, we proposed a novel framework, in which cross-system threats from terrestrial and marine human activities are taken into account. The integrated assessment of the coastal habitat quality was realized by using the intertidal zone as a bridge after evaluating the two subsystems of the terrestrial and marine independently. Nantong, a typical development coast in Southern Yellow Sea, was used as a case study. The results showed that in 2020, the trend of the coastal habitat quality in Nantong steadily improved from the terrestrial to the marine. The distribution of the coastal habitat quality in Nantong was significantly polarized. The direction of the habitat quality distribution in Nantong’s coastal zone was generally northwest-southeast. Human activities and benthic biodiversity are the main factors affecting habitat quality in Nantong’s coastal zone. This study is a useful attempt of cross-system habitat quality assessment, which can support integrated land-sea conservation planning and integrated coastal management.

Ecological succession (sequential replacement of species following a disruptive event) is critical for understanding ecosystem dynamics. With coral reefs facing increasing threats, comprehending secondary ecological succession is of heightened importance. Coral reef restoration, through techniques such as coral transplantation and herbivore introduction, plays a crucial role in mitigating coral degradation at the local scale. However, the combined effect of these two techniques on ecological succession remains understudied. To determine the impact of herbivory and coral transplantation on ecological succession, four experimental conditions were evaluated on reef patches (Bora Bora, French Polynesia): (i) no-restored control, (ii) restored control, and two conditions with herbivorous invertebrates introduced (sea-urchins and mollusks) alongside restoration: (iii) one site with macroalgae removal and (iv) one without. Macroalgae cover and fish were monitored among the conditions over a 70-day period. Herbivorous invertebrates limited algae cover compared to control. However, no difference in fish assemblages was found in alpha diversity when comparing conditions over time. Changes in fish assemblages were observed in beta diversity, with statistically supported values for juveniles in the restored condition with herbivorous invertebrates present. Understanding the dynamics of ecological succession in so complex environments like coral reefs is essential for designing effective restoration strategies and safeguarding their health.

In Peninsular Malaysia, the various forms and contexts of assessing the conservation status of a protected area has led to inconsistent results, causing misunderstanding and uncertainty among protected area managers. Furthermore, these assessments rely heavily on the conservation value inside the protected area, despite the fact that its value is also influenced by the external environment. In this regard, using a composite index of conservation value (CICV) provides the opportunity for a more practical assessment of conservation status. Therefore, the objective of this study was to develop a CICV to determine the conservation status of two protected areas in Peninsular Malaysia, i.e., the Krau Wildlife Reserve and Tasek Bera Ramsar Site. Land use/land cover maps inside and outside the protected areas, developed using Landsat images from 2014, were the basis for the conservation value assessment, which employed three landscape scale indicators, i.e., naturalness, fragmentation, and connectivity. Through an analytical hierarchical process, the indicators were combined to develop a CICV inside and outside each protected area. Acceptable robustness values obtained through sensitivity analysis enabled the calculation of the CICV scores. For each protected area, the internal and external sites were then merged to calculate a net CICV. The inside, outside, and net CICV scores were used to determine the area’s conservation status on a critical value scale with the markers ‘very critical’, ‘critical’, ‘moderate’, ‘good’, and ‘excellent’. Inside the Krau Wildlife Reserve, the CICV was 88.4 %, indicating an ‘excellent’ conservation status, while its outside status is ‘critical’ with a CICV of 35 %. The net CICV of this area was 64.29 %, yielding a ‘good’ net conservation status. The CICV inside and outside Tasek Bera Ramsar Site were 35 % and 21.34 % respectively, both of which represent a ‘critical’ conservation status. The net CICV was found to be 22.52 %, suggesting that the net conservation status is ‘critical’. The results show that the external landscape of protected areas is a threat that influences the areas’ net conservation status. Therefore, a comprehensive conservation status assessment requires a composite index that integrates conservation values from the outside to help protected area managers easily understand and interpret findings, and thus, effectively coordinate conservation planning.
