Trophic ecology of sympatric sea turtles in the tropical Atlantic coast of Brazil

The Tropical Atlantic coast of Brazil is a hotspot area for multiple sea turtle species at all life stages. The multiple nearshore reefs and beaches, oceanic islands, and the only atoll in the south Atlantic Ocean, are suitable for year-round foraging, migration corridors, and nesting activities of five sea turtle species. Still, relatively few studies have assessed trophic niche among sympatric sea turtles which can provide a better understanding of how closely related species compete/partition the available resources. Using multiple biogeochemical tracers (i.e., nitrogen (δ15N) and carbon (δ13C) stable isotopes, and mercury (Hg)), we disentangled the trophic niches of four sea turtle species – the green turtle (Chelonia mydas), the loggerhead turtle (Caretta), the hawksbill turtle (Eretmochelys imbricata), and the olive ridley turtle (Lepidochelys olivacea) – co-occurring in nesting and foraging habitats along the northeastern coast of Brazil. We found interspecific differences in isotopic and contamination niches, as well as intraspecific niche variation associated with life stage. Differences in the estimation niche models associated to life-stage in C. caretta support the notion of ontogenetic shift in habitat and diet composition previously reported for this species. Oceanic habitat signatures were observed in juvenile green turtles and adult olive turtles, while nearshore habitat signatures were observed in adult hawksbill turtles.

Under pressure: suitable areas for neotropical cats within an under protected biodiversity hotspot

Understand which factors influence the distribution of feline species can contribute to better planning of conservation strategies in a biodiversity hotspot. We modeled the potential distribution of seven cat species occurring in the Atlantic Forest (AF). Here, we combined climatic and landscape perspectives to determine the most suitable areas considering the taxonomic richness of these cats. We also assessed the ability of fully protected areas (FPAS) to protect these cat species. The results indicated that only 30% of the AF remnants are suitable for all species. Areas with low species richness were located in Argentina and northeastern Brazil. For taxonomic richness, the Serra do Mar (45.89%) and the Araucaria (27.90%) sub-regions had the highest suitable areas, followed by the Interior sub-region (21.89%). The Brejos Nordestinos and Pernambuco sub-regions had less than 1% suitability. Considering taxonomic richness, only 9% of suitable areas are covered by FPAs. Leopardus emiliae (1.37%) and Panthera onca (1.97%) had the lowest values of suitable areas covered by FPAs. The other species of cats are also under low protection (L. guttulus = 5.38%, L. wiedii = 5.71%, Herpailurus yagouaroundi = 6.70%, L. pardalis = 3.85%, and Puma concolor = 4.94%). We reveal that a low percentage of suitable areas are currently fully protected. This study also provides important conservation measures to be implemented in different AF sub-regions. These findings may help in the planning, maintenance, and implementation of FPAs through restoration programs and the establishment of ecological corridors.

Importance of ecosystem services and ecological security patterns on Hainan Island, China

The identification and restoration of damaged ecosystems are key to achieving ecological conservation and sustainable. Hainan Island is experiencing a serious crisis of biodiversity and habitat degradation. Therefore, its ecological conservation has become a priority and challenge for China. This study aimed to construct a multi-level ecological security pattern (ESP) based on the synergy of multiple ecosystem service functions and identify important ecological elements and ecological restoration areas. Based on the InVEST model, the circuit theory model, and a series of GIS spatial analysis methods, the importance of ecosystem functions (biodiversity maintenance, water conservation, carbon sequestration, and soil conservation) was evaluated, and ecological sources, ecological corridors, ecological pinch points, and ecological barrier points were identified. The results are as follows: 1) The best habitats in Hainan Island were distributed in the central mountainous area with diverse ecosystems, with an area of 10982.5 km2, accounting for 34.25% of the total suitable habitats. Low-level habitats are mainly distributed on tableland and coastal zones. Human disturbance is the direct cause of landscape patch fragmentation in low-level habitat areas. 2) A total of 65 large ecological sources with a total area of 8238.23 km2 were identified, which were concentrated in the biodiversity and water conservation areas in the central part of the island. 3) Crucial areas in Hainan Island mainly comprised forests and water bodies. Ecological corridors radiated across the entire area in the form of a spider web and connected all important ecological patches, including 138 ecological corridors (73 primary ecological corridors and 65 secondary ecological corridors), 222 ecological pinch points, and 198 ecological barrier points. In addition, the identified areas for restoration are primary areas in urgent need of protection and restoration. In general, the ecological pinch points are natural conservation areas supplemented by anthropogenic restoration, and the ecological barrier points demand equal attention for anthropogenic restoration and nature conservation. The ecosystem protection plan developed in this study will enrich the theoretical achievements of territorial spatial ecological planning in Hainan Island, and provides clear guidance for alleviating the contradiction between land use and economic development in Hainan Island.

Identifying ecological security patterns to prioritize conservation and restoration：A case study in Xishuangbanna tropical region, China

Parties to the Convention on Biological Diversity adopted the Kunming-Montreal Global Biodiversity Framework (Kunming-Montreal GBF), which puts forward higher ecological conservation requirements for countries to carry out sound spatial planning to realize the ultimate vision of harmonious coexistence between humanity and nature. It is urgent to adopt a comprehensive and refined spatial planning method to provide spatial guidance for efficient actions. Ecological security patterns (ESP) are an integrated approach that effectively reduces the impact of production and daily life on nature, promoting regional ecological sustainability, which can provide efficient spatial planning support for Kunming-Montreal GBF implementation. Taking the Xishuangbanna tropical region as a research case, a biodiversity hotspot in China and the world, this study attempts to improve and optimize the ecological network construction process of the ESP research paradigm “ecological sources identification-ecological resistance surfaces construction-ecological corridors extraction" around higher ecological objectives, and further identifies the priority areas for ecological conservation and restoration. Overall, it has been determined the ecological network spaces of five species groups in the Xishuangbanna tropical region. Key biodiversity areas of 2768.19 km2 play an important maintenance role in the overall biodiversity and ecosystem services of the region, and 213 high importance and connectivity corridors that have significant contributions to the migration of species are determined. The priority areas for ecological conservation (2467.71 km2) and ecological restoration (514.67 km2) are further determined. This study provides a demonstration case for constructing an integrated ESP to maintain regional species and ecosystem stability, enhance integrity and connectivity, and further identify priority areas. For the Xishuangbanna tropical region and other global biodiversity hotspots, a systematic, comprehensive, and sustainable ecological management model should be established, where limited funding and resources for ecological actions should be directed to priority areas of the most valuable outcomes.

Unpaved road verges are attractive habitats for dung beetles (Coleoptera: Scarabaeidae) in a plantation forestry-grassland mosaic

Roads have direct and indirect impacts on biodiversity, although the impacts on insects are not yet fully understood. In a plantation forestry-dominated landscape in South Africa, where natural grasslands make up ecological networks of conservation corridors among plantation compartments, we investigated the impact of maintained unpaved roads and unmanaged tracks on dung beetles. We show that these two types of roads have little impact on dung beetle species richness and assemblage structure, indicating that road verges are attractive habitats for dung beetles. Yet, nocturnal dung beetle abundance increased with distance away from roads, suggesting that areas farther away from roads are important to maintain their population sizes. Vegetation characteristics, especially total cover by grasses and overall vegetation height, were important drivers of dung beetles, yet substrate characteristics were unimportant. With vegetation characteristics being related to road maintenance, roads in the landscape have an indirect impact on dung beetle species richness, abundance, and assemblage composition, rather than a direct impact. Road construction in production landscapes is unavoidable, and their edges are attractive to dung beetles. This means that road users should avoid unnecessary road killings by strictly keeping to the road tracks. Habitat heterogeneity across the overall landscape should be encouraged to minimize current and future impacts of roads on dung beetles. The expansion of road networks, or the maintenance of existing road networks, should be done cautiously so as to promote habitat heterogeneity which is important for maintaining regional dung beetle diversity patterns.

Connecting the dots: Using social network analysis to disentangle the factors driving international migration

AbstractMigration scholars and policymakers continue to question why international migration corridors develop. In the current project, I argue that there is value in applying a social network approach to disentangle the processes that drive international migration. Using data on migration between 173 countries from 2010 to 2015, I construct a migration network where nodes are countries and edges are flows weighted by the number of people making an international move. Then, I apply valued exponential random graph models to determine whether multiple factors govern the global movement of people. I find that the international migration network is defined by an overrepresentation of transitive triads and unreciprocated dyads, even when multiple economic, migrant network, macro‐level and environmental factors are also considered. Results suggest that after accounting for the volume of migration flows and various, theoretically‐informed drivers of international migration, the network continues to resemble a stratified ranking of destinations.

Endoscopic Endonasal Transsphenoidal Transcavernous Transoculomotor Triangle Approach for Resection of an Invasive Pituitary Adenoma Extending Into the Parapeduncular Space Through the Cavernous Sinus.

A subset of invasive pituitary adenomas invade not only the medial wall of the cavernous sinus but can progress superiorly through the cavernous sinus roof at the oculomotor triangle and reach the subarachnoid parapeduncular space. We describe a series of 2 of 3 cases where an endoscopic endonasal approach was used to reach the parapeduncular space through the oculomotor triangle for tumor decompression. Images of the third case are presented. Case 1: We present a 2-dimensional surgical video of a recurrent corticotroph adenoma post gamma knife radiotherapy which was invading the left cavernous sinus and extending into the left parapeduncular space. Histopathological examination revealed densely granulated corticotrophin adenoma. The patient had reduction in the serum cortisol level postoperatively and was induced into remission medically. Postoperative third nerve palsy recovered partially, and sixth nerve palsy recovered completely at the 3-month follow-up. Case 2 : A case of recurrent silent corticotrophin adenoma invading the right parapeduncular space through the right cavernous sinus was operated through the same approach as case 1. Only a subtotal excision of the tumor in the cisternal space was possible. The patient developed a complete right third cranial palsy in the immediate postoperative period with near total recovery at the 6-month follow-up. Endoscopic endonasal approach to the parapeduncular space through a transcavernous transoculomotor route is reasonably safe and effective, as long as key anatomic landmarks and structures are identified and preserved while using natural tumor corridors to achieve tumor clearance.

Identifying Ecological Security Patterns Considering the Stability of Ecological Sources in Ecologically Fragile Areas

Ecological security patterns (ESPs) provide an effective spatial approach for identifying critical conservation areas and ensuring regional ecological security. However, prior research has not paid much attention to the importance of the stability of ecological sources in time-series changes, which is especially critical for maintaining ecological functions in ecologically fragile areas. Focusing on the Ningxia Hui Autonomous Region (NHAR) of China, this study evaluated the spatiotemporal change patterns in ecosystem services importance (ESI) from 2000 to 2020, integrating the spatial principal component analysis (SPCA) and circuit theory to propose a novel ESP construction framework that aims to address the issue of insufficient consideration of source stability. A total of 93 stable ecological sources were identified, with the capacity to ensure the continuous provision of high-level ecosystem services and resistance to external disturbances. The extraction of 234 ecological corridors and 430 ecological nodes effectively enhanced the stable flow of ecological processes and connectivity. The stable ESP, constituted by the above ecological elements, can serve as core ecological space and basic skeleton to maintain the regional sustainable landscape. This study provides scientific references for identifying key priority conservation areas and formulating targeted ecological conservation and restoration strategies in ecologically fragile areas.

The Entanglement Between Tangible and Intangible Factors in Shaping Hadiya Migration Aspirations to South Africa

This article expands scholarly knowledge on migration decision-making drawing on the case of Hadiya (Southern Ethiopia) migration to South Africa. We propose a conceptual framework where intangible factors (religious beliefs, imaginations, norms, and emotions, and feelings) are placed at the core of decision-making, alongside more tangible factors, such as livelihood opportunities. Even though we differentiate between intangible and tangible, we reject any opposition between the two, arguing that they inform and reinforce each other. The Hadiya—South Africa migration corridor emerged from a foundational evangelical Christian prophecy in 2001, which coincided with other events in the Hadiya zone, such as increasing pressure on farmlands, the politicization of internal migration, and more liberal migration policies. Drawing on extensive qualitative data, we focus on the relevance of intangible factors in Hadiya migration to South Africa, bringing to the fore an understudied aspect of decision-making. Showing the centrality of such aspects in Hadiya respondent's life stories, we argue that only by looking at the interplay of intangible and tangible factors we can reach a better understanding of the complex dynamic of migration decision-making.

Assessing the Connectivity of Urban Green Spaces for Enhanced Environmental Justice and Ecosystem Service Flow: A Study of Tehran Using Graph Theory and Least-Cost Analysis

This research aims to analyze the relationship between environmental justice and urban green space connectivity in Tehran, Iran. The evaluation of green space connectivity in this study is conducted through two distinct cost layers: one aimed at enhancing existing connections and another focused on establishing new green spaces. Key factors influencing connectivity, extracted from the relevant literature, were identified to facilitate this analysis. Employing graph theory and least-cost analysis, the results determined critical resistance factors, current connectivity and cost status, the varying degrees to which different districts benefit from green space ecosystem services, and the most effective routes for establishing green corridors. Research findings highlight significant disparities in access to these services, particularly in the underserved central districts of Tehran. Moreover, spatial analysis reveals a higher potential for enhancing east–west ecosystem service corridors due to the higher density of green hubs and lower costs in this orientation, while north–south connectivity faces more challenges. By exploring land use/land cover, and physical and socio-economic factors affecting urban green space connectivity, this study provides urban and environmental planners with a novel methodology and comprehensive insights for effective decision making, resource allocation, and land use planning.

Can the Impact of Gravel Roads on Organic Layer Thickness Explain the Distribution of Populus tremuloides along Road Networks in the Boreal Forest of Eastern Canada?

Roads are known to alter environmental conditions and the composition of road edge plant communities, particularly when exogenous materials are used as road surfacing. In this study, we evaluate the impact of gravel roads on the organic layer thickness (OLT) and aspen distribution in a boreal forest landscape of Eastern Canada. The OLT and aspen distribution were compared at different distances from the roads (0 m, 10 m, and >10 m) to determine whether a reduction in the OLT along the roads could explain the distribution of aspen along the road network, and in particular the role of the roads as habitat corridors. In addition, germination tests were carried out to determine whether mineral soil from the roads could promote aspen establishment, by comparing the germination rate of substrates consisting only of mineral soil or mosses, and substrates consisting of mosses covered with 0.5 cm or 2 cm of mineral soil. The presence of aspen in the study landscape is limited by thick organic deposits (≥50 cm). However, the thickness of these deposits is reduced to approximately 10 cm at the edges of gravel roads, in part by the transport of mineral soil from the roads. This reduction in the OLT facilitates the establishment of aspen and helps explain its distribution along the road network.

Wildlife corridor degradation and human‐wildlife conflict: A case study from Tanzania

AbstractIn many African countries, anthropogenic pressure and poor governance have led to the degradation of wildlife corridors, which are important for the long‐term viability of wildlife populations. Yet the nature of such degradation is poorly understood, hindering our ability to reverse these trends. We studied a deteriorating wildlife corridor between Katavi and Mahale National Parks in western Tanzania. Using satellite imagery, we found that the corridor still contains large areas of natural vegetation, diverse terrain and numerous water sources. There has nonetheless been increasing encroachment of the corridor by people between 1990 and 2017, exemplified by a 9% reduction in the area covered by miombo woodlands and a fourfold increase in the area covered by settlements and agricultural land. We used three additional methods to assess deterioration over the last three decades: elephants' movement routes, peoples' perception of animal populations and incidents of human–wildlife conflicts. Elephants were primarily found only in the parts of the corridor adjacent to the two national parks. Tracking of elephant spoor revealed a much‐diminished corridor use, suggesting that seemingly ‘healthy’ habitat within a wildlife corridor will not necessarily predict the presence of elephants or perhaps of other species. Other factors particularly the increasing presence of humans in the area are possibly more important for predicting elephant use of a corridor. Interviews with local residents and conservation experts suggested that, although use by some animal species has declined, many ungulates were still seen in the corridor and neighbouring villages, some of which were associated with human–wildlife conflict. All villages around the corridor were affected by the human–wildlife conflict; this comprised crop damage, livestock injury or killing and attacks on humans. We conclude that corridors could be restored if people were restricted from settling, but this would require governments to enact policies that balance the conservation of Natural Capital with survival of human populations; the latter may involve internal migration in response to growing population pressures.

Impacts of multi-scenario land use change on ecosystem services and ecological security pattern: A case study of the Yellow River Delta

The Yellow River Delta (YRD), a critical economic zone along China's eastern coast, also functions as a vital ecological reserve in the lower Yellow River. Amidst rapid industrialization and urbanization, the region has witnessed significant land use/cover changes (LUCC), impacting ecosystem services (ES) and ecological security patterns (ESP). Investigating LUCC's effects on ES and ESP in the YRD is crucial for ecological security and sustainable development. This study utilized the PLUS model to simulate 2030 land use scenarios, including natural development (NDS), economic development (EDS), and ecological protection scenarios (EPS). Subsequently, the InVEST model and circuit theory were applied to assess ES and ESP under varying LUCC scenarios from 2010 to 2030. Findings indicate: (1) Notable LUCC from 2010 to 2030, marked by decreasing cropland and increasing construction land and water bodies. (2) From 2010 to 2020, improvements were observed in carbon storage, water yield, soil retention, and habitat quality, whereas 2020–2030 saw increases in water yield and soil retention but declines in habitat quality and carbon storage. Among the scenarios, EPS showed superior performance in all four ES. (3) Between 2010 and 2030, ecological sources, corridors, and pinchpoints expanded, displaying significant spatial heterogeneity. The EPS scenario yielded the most substantial increases in ecological sources, corridors, and pinchpoints, totaling 582.89 km2, 645.03 km2, and 64.43 km2, respectively. This study highlights the importance of EPS, offering insightful scientific guidance for the YRD's sustainable development.

Construction and optimization of ecological network based on morphological spatial pattern analysis and minimum cumulative resistance models in Haihe River basin

AbstractIn recent years, landscape fragmentation has become increasingly serious due to the impact of human activities. The ecological network can ensure the ecological function of the region through linearly connecting ecological corridors and effectively solving the problem of landscape fragmentation that occurs in the evolution of landscape patterns. Based on MSPA and MCR models, the article analyses the distribution and changes of landscape types in the Haihe River basin and constructs an ecological network in the study area by combining the local ecological characteristics of the basin. The network structure is optimized in the end by selecting three large stepping stones, constructing 69 internal ecological stepping stones, identifying 212 fracture points, and adding seven ecological corridors to build a point–line surface network structure with an internal and external double‐loop structure. The connectivity of the network structure is evaluated by using complex network method. It is calculated that the network connectivity performance is improved by 13.95% after optimization, which means the species exchange in the study area is closer.

Identification of priority areas for territorial space ecological restoration in arid area of Northwest China: A case study of Zhangye City in Heihe River basin.

Determining priority areas for territorial ecological restoration in the arid region of Northwest China based on the holistic protection and systematic governance is an important measure to build solid national ecological security barrier and promote the construction of territorial ecological civilization. Taking Zhangye City, a typical arid area city in Northwest China, as an example, we constructed the research framework of "ecological network-ecological sensitivities-ecological degradation" from two aspects of internal defects and external threats of ecological networks by using circuit theory and assessment methods of ecological service function importance, ecological sensitivity, and ecological degradation. We then identified the priority areas of territorial ecological restoration in northwest arid region and put forward the restoration strategies. The results showed that the priority areas of ecological restoration in Zhangye City were concentrated in the artificial shelterbelt along rivers and the plain-desert-oasis transition zone with fragile ecology and strong human interference. The ecological network of the study area included 39 ecological sources and 99 ecological corridors, and the highly sensitive and degraded areas were 1595.40 and 6.65 km2. Based on the internal defects and external threats of the ecological network, we identified 31 ecological pinch points, 7 obstacle points, and 753.56 km2 ecological source areas in the territorial spatial ecological restoration priority area. These areas were related to the connectivity of the ecological network internally and the stability maintenance of the ecosystem outwards, and were the areas to restoration in the future. Following the concept of overall protection and system restoration of territorial space, we put forward the idea of territorial space restoration by integrating internal defects and external threats of ecological network, which could provide scientific decision-making basis for comprehensive ecosystem management and territorial optimization of Zhangye City.

Forest fragmentation causes an isolated population of the golden takin (Budorcas taxicolor bedfordi Thomas, 1911) (Artiodactyla: Bovidae) in the Qinling Mountains (China)

Budorcas taxicolor bedfordi is a rare animal uniquely distributed in the Qinling Mountains (China). Human disturbance and habitat fragmentation have directly affected the survival of B. t. bedfordi. It is urgent to clarify the genetic diversity and genetic structure of the B. t. bedfordi population and implement effective conservation measures. In this study, 20 new polymorphic microsatellite loci were isolated by Illumina sequencing. The genetic diversity and population structure of 124 B. t. bedfordi individuals from three populations (Niubeliang population, Zhouzhi population, and Foping population) were analysed according to these 20 microsatellite loci. Our results indicated that B. t. bedfordi had a low level of genetic variability and that there was inbreeding in the three populations. The population genetic structure analyses showed that the Niubeliang population had a trend of differentiation from other populations. National roads can affect population dispersal, while ecological corridors can promote population gene exchange. None of the three B. t. bedfordi populations experienced bottleneck effects. For conservation management plans, the Zhouzhi population and Foping population should be considered one management unit, and the Niubeliang population should be considered another management unit. We suggest building an ecological corridor to keep the habitat connected and formulating tourism management measures to reduce the influence of human disturbance on B. t. bedfordi.

Water transportation planning in connection with extreme weather conditions; case study – Port of Novi Sad, Serbia

Abstract The Danube has a length of 588 km in the Republic of Serbia. The water transport on this river is underused. The hazardous events have a great impact on the traffic on this river, and the understanding of these events is of great importance. This study focuses on hazardous events on the Danube with the main focus on the port of Novi. The hazardous events used in this study are extreme air temperatures, devastating winds, drought, and heavy precipitation. The hazardous events were represented using geographic information systems (GIS), geostatistics, and numerical methods. The potential of the river transport network and the port capacity were analyzed and compared with the hazardous events of the last 30 years. The results showed that three areas of the port are of great importance for port security, and two areas are extremely affected by hazardous events. The distance of the port of Novi Sad from heavy precipitation events is 6.8 km in the southwestern direction. The periods of extremely low precipitation (climatic drought) were in 1994, 2008, 2012, 2015, 2019, and 2021. Extreme average maximum temperatures were in 1995, 2008, 2010, 2013, 2015, and 2019. On the other hand, minimum average temperatures were in 1994, 1996, 1998, 1999, 2017, and 2018, and the strongest winds were in 1995, 1998, 2003, 2009, 2012, and 2014. The methods and techniques of GIS, used in this research, have confirmed new potential geographical positions of the port that can be better adapted to future climate changes. Another main objective of this research is to recommend better spatial planning and construction of new green corridors.
