Published: Jan. 20, 2022

The global decline of coral reefs has led to calls for strategies that reconcile biodiversity conservation and fisheries benefits. Still, considerable gaps in our understanding the spatial ecology ecosystem services remain. We combined information on larval dispersal networks estimates human pressure test importance connectivity service provision. found receiving larvae from highly connected corridors were associated with high fish species richness. Generally, "sinks" contained twice as much biomass "sources" exhibited greater resilience when protected. Despite their potential support persistence sustainable fisheries, up 70% important corridors, sinks, source remain unprotected, emphasizing need increased protection well-connected reefs.

Towns and trails drive carnivore movement behaviour, resource selection, and connectivity

Movement Ecology, Journal Year: 2022, Volume and Issue: 10(1)

Published: April 8, 2022

Abstract Background Global increases in human activity threaten connectivity of animal habitat and populations. Protection restoration wildlife movement corridors require robust models to forecast the effects on behaviour, resource selection, connectivity. Recent research suggests that selection responses depend their behavioural state, with increased tolerance for fast states movement. Yet, few studies have incorporated state-dependent behaviour into analyses Merriam connectivity, is individual-based metrics incorporate landscape structure behaviour. Methods We assessed cumulative anthropogenic development multiple processes including simulated paths using hidden Markov step functions estimate use three scenarios: reference conditions no development, current conditions, future a expansion towns recreational trails. Our analysis used 20 years grizzly bear ( Ursus arctos ) gray wolf Canis lupus data collected around Banff National Park, Canada. Results Carnivores speed travel near areas high trail road density, presumably avoid encounters people. They exhibited stronger avoidance when foraging resting compared travelling during day night. Wolves than bears. Current reduced amount high-quality between two mountain by more 35%. Habitat degradation constrained routes was most pronounced from an average 85%. quality further declined under scenario. Conclusions results highlight carnivore use, strong behaviour-specific suggest conservation initiatives should consider how proposed developments actions would affect where animals they landscape.

Priorities for protected area expansion so nations can meet their Kunming‐Montreal Global Biodiversity Framework commitments

Integrative Conservation, Journal Year: 2023, Volume and Issue: 2(3), P. 140 - 155

Published: Sept. 1, 2023

Abstract As part of the Kunming‐Montreal Global Biodiversity Framework (K‐M GBF), signatory nations Convention on Biological Diversity (CBD) aim to protect at least 30% planet by 2030 (Target 3). This bold ambition has been widely celebrated and its implementation seen as pivotal for overall success K‐M GBF. However, given that many CBD prioritised quantity (e.g., area) over quality important areas biodiversity) when attempting meet their 2010 Aichi protected area commitments, it is critical focus protecting those terrestrial, inland waters marine have best chance halting reversing biodiversity loss thus contribute Goal A Here we provide a review type need prioritise implementing Target 3 relates ‘quality’: particular importance ecosystem functions services, are effectively conserved managed through ecologically representative, well‐connected equitably governed systems .

Scaling up area-based conservation to implement the Global Biodiversity Framework’s 30x30 target: The role of Nature’s Strongholds

PLoS Biology, Journal Year: 2024, Volume and Issue: 22(5), P. e3002613 - e3002613

Published: May 21, 2024

The Global Biodiversity Framework (GBF), signed in 2022 by Parties to the Convention on Biological Diversity, recognized importance of area-based conservation, and its goals targets specify characteristics protected conserved areas (PCAs) that disproportionately contribute biodiversity conservation. To achieve GBF’s target conserving a global area 30% 2030, this Essay argues for recognizing these scaling them up through conservation are: extensive (typically larger than 5,000 km 2 ); have interconnected PCAs (either physically or as part jurisdictional network, frequently embedded landscapes); high ecological integrity; are effectively managed equitably governed. These presented “Nature’s Strongholds,” illustrated examples from Congo Amazon basins. Conserving Nature’s Strongholds offers an approach scale initiatives address threats biodiversity.

Planning for the Restoration of Functional Connectivity in Brazil

Journal of Biogeography, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 20, 2025

ABSTRACT Aim Land use and land cover (LULC) change is the main driver of biodiversity loss, causing habitat loss fragmentation that hinders species movement negatively impacts populations. While fragments are structurally disconnected, functional connectivity can still occur depending on species' dispersal abilities. Incorporating landscape into restoration planning helps identify strategic areas significantly enhancing connectivity. Here, we present an unprecedented, nationwide continuous spatial layer representing each restorable pixel's contribution to connectivity, using Brazil as a case study. Location Brazil. Methods We performed dynamic pixel‐based analysis across Brazilian biome assess potential increases in Integral Index Connectivity (IIC) resulting from restoring pixel landscape. For that, defined hypothetical with medium, high very abilities calculated IIC for different natural LULC biome. Then, ran Results Our dataset represents relative landscape, considering all Since assessing contributions individual pixels overall most values expectedly low. However, highest show stand‐alone biome‐wide thus were interpreted priorities restoration. Notably, nested regions restoration, trend higher priority rankings (e.g., top 5% important regions) being surrounded by subsequent priorities.

The Green Corridors Plan (Eixos Verds Plan), proposed by the Barcelona City Council, aims to enhance urban well-being, environmental sustainability, and resilience transforming one in every three streets into green corridors. Although initially designed for city-wide implementation, only first phase, focused on centric Eixample district, has been completed, overall plan implementation postponed. Our aim is evaluate health co-benefits of implementing citywide, focusing direct effects increased exposure greenness impact temperature reduction mortality.

Bolivia’s national parks, with their rich biodiversity and natural landscapes, have great potential to contribute own financial sustainability, tourism is one of the most promising sustainable activities that can make this possible. Entrance fees parks are a vital source income for National Service Protected Areas, yet significant gap remains. This study estimates tourists’ willingness pay (WTP) increased entrance in two protected areas, comparing data from 2019 2023 assess effect COVID-19 on WTP. Using contingent valuation approach, we found profiles WTP shifted between 2023. However, there was no consistent trend across highlighting challenges specific impacts pandemic tourists Nevertheless, findings help inform pricing strategies aimed at enhancing sustainability supporting broader conservation goals both nationally globally.

Europe has unique natural values but also the highest level of ecosystem fragmentation. Evaluating effectiveness protected area management is becoming an increasingly common practice. Our main goal was to assess dynamics LULC changes in buffer zones 159 national parks 11 selected European countries on basis CORINE Land Cover database period from 1990 2018. We used five landscape metrics order investigate whether high and areas surrounding affect degree rate fragmentation isolation. checked statistical significance differences measured among different distances (1, 2 3 km) years using two-way ANOVA test. Furthermore, classical principal component analysis method applied measure data grouped by country then averaged year distance factor. showed that The patch density index shows evident increase, both dynamic terms (1990–2018) and, mainly, spatial aspect. In 2018, there increasing approximately 5–7% compared 1990. It should be kept mind efforts focused may have limited success. Undoubtedly, obtained results will contribute development ecology developments context effective their surroundings.
