The conflict between multiple functions of human use and habitat conservation represents an intractable challenge for environmental management. While numerous studies on marine prioritize cumulative impact assessments (CIA) to tackle this issue, estuaries — despite their immense significance amidst intense activities remain overlooked. Taking the Yangtze River Estuary (YRE) as case study area, it is one most intensely human-utilized globally, yet serves a critical migratory corridor endangered Chinese sturgeon (Acipenser sinensis).We employed ecological indicators quantitative modeling assess suitability anthropogenic impacts species in YRE. results demonstrated that suitable distribution varied juvenile was concentrated Chongming Dongtan North Channel.

Our spatially explicit indicator-based findings provide key scientific support enlarging protected implementing adaptive balance sustainable highly utilized ecosystem.

Published: Aug. 4, 2022

Marine-coastal ecosystems are productive and valuable habitats worldwide due to their significant contributions human wellbeing. However, activities, limited territorial planning, unsustainable demand consumption of natural goods services put pressure on marine-coastal ecosystems. In this sense, planning is a management tool contrast these forces because it manages different activities the coast in oceans over space time, strengthening political, social, tourist development economy territory. Our objective propose spatial strategies through an ecosystem-based approach for allocating mangrove estuarine zone conservation area. The study methodology is: (i) Compilation information from area with emphasis regulations protected areas. (ii) Analysis relations (iii) Mapping zoning (iv) strengths, weaknesses, opportunities, threats threats, strengths (SWOT–TWOS) matrix recommend guarantee viability protection. results show maps sector proposed as comprising mangroves zone. It also approaches governance or measures protection space. Finally, recommendation, we improvements current municipal ordinances, guaranteeing area, furthering achievements comprehensive land-use planning.

Stranding data provide fundamental information on biometric traits of cetaceans useful to increase knowledge ecological and their consumption patterns. In this study, the length weight (L-W) relationships through power regression model (W=a×Lb) were calculated for three dolphin species (the striped dolphin, common bottlenose Risso's dolphin) in several Mediterranean subregions at scale entire basin. Length (L) (W) collected from stranding records during period 1983 2021 acquired databases literature. Starting L-W relationships, a bootstrap method was applied estimate mean body weights, daily ingested biomass (IB) annual food (AFC) rates different species. particular, four equations used IB rates.
