This study is the first to evaluate fish provisioning services of a whole transitional landscape (Ria Formosa lagoon, Portugal), in parallel with enhancement growth, survival and production single cohorts most important commercial species by vegetated unvegetated sub-tidal habitats. Based on monthly beach seine samples, total density biomass 96 fishes were 1.89 3.03 times greater habitats than habitats, respectively. Vegetated habitat enhanced six eight for which could be estimated both The all 12 commercially within was approximately double that habitat, 7 ranging from 1.8 169-fold Within covers an area 5-fold smaller yet it accounts 27.1 % production. Estimated lifetime economic values between 30 million 59 EUR.

These results highlight enormous importance temperate coastal lagoons as nursery source recruits fisheries. Our evaluation based data individual stronger more valid approach estimating future value previous studies mean densities biomasses did not distinguish cohorts.

These ecosystems are threatened multiple stressors, including loss climate change, but relative types for different remains poorly understood since direct comparisons rare. This knowledge gap is exemplified in temperate salmon—ecologically commercially important during their migrations from ocean. Here, we tested species-specific sampling fishes 3 interconnected (brackish marsh, eelgrass, sand flat), across seasons temperature regimes. We quantified richness, community distinctness, catches (of Chinook chum fishes, fishes) Pacific Northwest’s heavily urbanized Fraser River estuary, terminus what was once world’s most productive salmon basin. Overall, eelgrass supported greatest richness (n = 37) (37402 fish), exceeding both marsh (19 species, 7154 fish) flat (22 6697 fish). However, majority were caught (61%). differences, coupled finding at least one unique inhabited each (eelgrass 15, 8, 1), demonstrate underscore connected seascapes biodiversity conservation.

Nursery grounds provide conditions favorable for growth and survival of juvenile fish crustaceans through abundant food resources refugia, enhance secondary production populations. While small-scale studies remain important tools to assess nursery value structured habitats environmental factors, targeted applications that unify survey data over large spatial temporal scales are vital generalize inference function, identify highly productive regions, inform management strategies. Using 21 years spatio-temporally indexed (i.e., water chemistry, turbidity, blue crab, predator abundance) GIS information on potential seagrass, salt marsh, unvegetated shallow bottom), we constructed five Bayesian hierarchical models with varying dependence structures infer variation in habitat young juveniles (20–40 mm carapace width) the crab Callinectes sapidus within three tributaries (James, York Rappahannock Rivers) lower Chesapeake Bay. Out-of-sample predictions counts from a model considering fully nonseparable spatiotemporal outperformed simpler models. Salt marsh surface area turbidity were strongest determinants abundance (positive association both cases). Highest abundances occurred near maximum where relative was greatest. Relative seagrass area, which has been emphasized as most valuable conducted at small scales, not associated high tributaries. Hence, marshes should be considered key even extensive beds occur. The patterns between variables also indicated identification nurseries based investigations broad incorporating multiple habitats, statistical analyses address dependence.

Coastal managers continue to be confronted with making management decisions few data available and insight of the outcomes. Practical tools that can used inform on effects different scenarios changes are particularly important assist decision-making. This study has applied a Bayesian Belief Network (BBN) investigate contrasting Sea Level Rise (SLR) reduction in tidal inundation tropical wetland mosaic including saltmarshes, mangroves, intertidal mudflats. We investigated: 1) habitability site for vegetation under associated inundation; 2) probability ecological values export crab zoea blue carbon supported scenarios. The highlights that, without ability adjust future SLR scenarios, saltmarshes here likely lost open water, scenario 0.8 m SLR. Tidal decreased mangrove cover but increased terrestrial subtidal herbaceous saltmarshes. is positively affect value decreases likelihood holding high zoeae saltmarsh areas. In contrast, declined both values. findings highlight importance "whole-of-system" approach assessing inundation. Focusing only one habitat single targeted may structure functions other components coastal ecosystem mosaic.

The shallow waters of the world's coasts comprise a variety ecosystems such as tidal wetlands, salt marshes, sand flats, rocky coasts, and coral reef encompass complexes pelagic benthic, vegetated unvegetated habitats. These disparate are bound together by one common feature; that pattern life for marine organisms, outcomes process functioning irrevocably influenced tide. Focusing on tide highlights unique component, intertidal zone – an area alternates between exposure to atmosphere inundation waters. While has diverse influences processes regulate ecological function in tidally dominated ecosystems, much this can be captured idea, multi-scale predictability tides provides vital information organisms utilising these systems. We explore idea considering dynamics nekton assemblages roles play those systems, how fundamentally differential responses their prey tides. Further, we discuss nature provide biota, trade-offs inherent available resources, strategies employed biota take advantage need strategic trade-offs.

Abstract: Recent statements from the Brazilian federal government indicate that impacting economic activities, particularly commercial shrimp farming, are being encouraged in mangrove areas near future. Alterations of National Action Plan and legal instruments partially protected ecosystems have created an even weaker framework than previously existed. Such changes leading Brazil far global call to conserve mangroves Aichi targets United Nations Sustainable Development Goals. Unfortunately, loss their ecosystem services will negatively impact living standards for Brazilians coastal areas.
