Climate change (CC) represents an increasing threat to mangroves worldwide and can amplify impacts caused by local anthropogenic activities. The direct effects of CC on mangrove forests have been extensively discussed, but indirect such as the alteration ecological processes driven specific functional groups biota are poorly investigated. Ecological roles key (FGs) in from Atlantic–Caribbean–East Pacific (ACEP) Indo-West (IWP) regions reviewed, mediated these FGs explored. Disruption processes, FGs, reinforce loss functionality further degradation forests. Biogeochemistry mediator microbiotas soil, bioturbators, especially semiterrestrial crabs (Ocypodoids Grapsoids) herbivores (crustaceans Insects), would be most affected FG both regions. Effects climate vary regionally function combination drivers, eroding biodiversity resilience, impairing predictability ecosystem behaviour. This means that public policies manage conserve mangroves, well rehabilitation/restoration programs, should take into consideration pressures response pressures.

Geoduck aquaculture is becoming a key component in meeting international market demand, given the natural and regulatory restrictions on wild geoduck supply. clams are not sexually dimorphic, making it practically unfeasible to distinguish between males females prior spawning event. To facilitate increased production of geoduck, better understanding reproductive biology associated targeted bio-markers required. In this study, metabolomics was utilised as research tool metabolites related male female New Zealand (Panopea zelandica), gill muscle samples collected from broodstock individuals housed an experimental hatchery. A total 17 were detected, showing significant differences sexes. The findings indicate that with lipid biosynthesis support functions. An increase carbohydrate-linked metabolic pathways detected arguably sustain sperm production. Taurine has been reported biomarker bivalves other studies confirmed within elevation adductor tissue. Moreover, had purine pyrimidine biosynthesis, supporting energy needs. This study provides useful sex biomarkers for future breeding strategies P. zelandica.

Abstract Acquiring food in heterogeneous landscapes presents a challenge to many foragers, as searching for an optimal manner is difficult spatially and temporally variable environments. Investigating individual foraging patterns can elucidate how environmental variations at different scales constrain or select energy-optimizing movements, which inform conservation management strategies by identifying spatio-temporal species’ habitat use. To test such movements vary with conditions, we investigated of the deposit-feeding sand-bubbler crab, Scopimera intermedia Balss, 1934 multiple spatial temporal on soft sediment shores Hong Kong. On broad, annual, scale crabs produced tracks length foraged over areas around their burrows between hot cool seasons. Although were slower more restricted during season, probably due low temperatures, season larger but limited increasing conspecific interactions. Over smaller make movement decisions, parameters turning angle speed variable, even within excursions. Such appeared be responses small-scale patches, resulted employing modes. This context-dependent strategy enables feed longer time food-rich patches compared fixed is, therefore, critical species living environments intertidal sediments, where distribution constrained tide.
