Summary: The study utilizes water quality monitoring data to analyze the seasonal and inter-annual variability in habitat for the copepod Acartia tonsa in Chesapeake Bay. Results show that the P-crit metric predicts the largest volume of unsuitable deoxygenated habitat over space and time, with dry conditions leading to a decreased extent of deoxygenated habitat. Although no clear relationship between copepod abundance and habitat availability was observed, the peak abundance of A. tonsa correlates with the extent of deoxygenated habitat using the P-crit metric.

Summary: This study used acoustic and satellite telemetry to investigate the population of juvenile smooth hammerhead sharks in the Azores archipelago and confirmed the existence of nurseries in this area. The sharks showed a preference for using coastal nurseries during the day and venturing further offshore at night, possibly to feed. These findings highlight the importance of understanding the ecological behaviors and implementing conservation measures for the smooth hammerhead shark.

Summary: The intensification of climate change and coastal development pressures has increased the demand for shoreline protection. Nature-based approaches using natural habitats as alternatives to grey infrastructure are being promoted globally. Research shows that both created living shorelines and natural marshes serve as nursery habitats for blue crabs, suggesting the potential of living shorelines to act as nursery habitats for economically important species.

Summary: Identifying suitable habitat and corridors for movement is crucial for biodiversity conservation in the face of climate change. This study focused on the Asiatic black bear population in the Northern Highlands of Pakistan and found both current and future suitable habitat areas. The model predicted an increase in suitable habitat under future scenarios, with a majority of the current suitable habitat identified as climate refugia. The results provide valuable information for conservation strategies and management plans to mitigate climate change impacts on Asiatic black bears.

Summary: This study investigated the thermal threshold for mass emigration of juvenile white sharks using acoustic telemetry tracking and high-resolution water temperature data. The findings showed that most sharks started searching for warmer water when the sea temperature dropped below 14 degrees Celsius, leading to mass migration of the population.

Summary: This study used 21 years of survey data and GIS information to evaluate the nursery habitat value of blue crabs in three tributaries of lower Chesapeake Bay. The results showed that salt marsh surface area and turbidity were the main factors affecting crab abundance, while relative seagrass area had no association. Therefore, the identification of nurseries should consider multiple potential habitats and incorporate spatial and temporal statistical dependence.

Summary: Designation of essential fish habitat requires understanding species-specific vital rates across habitats and regions. Brown shrimp is an economically important species occurring in various habitats across the southeastern US, exhibiting variation in vital rates. This study estimated growth rates of juvenile brown shrimp in intertidal creek habitat and found that they are similar to those in salt marsh habitats in northern GoM estuaries.

Summary: Baker & Sheaves criticize the Whitfield review for suggesting high predation pressure on juvenile fish in shallow estuarine nursery habitats, while research in South Africa supports the idea that shallow littoral areas provide refuge for small juveniles. More targeted research is needed to confirm the role of littoral estuarine waters as a universal keystone attribute.

Summary: The study analyzed the trophic ecology of four juvenile fish species in different habitats of a tropical estuary and found that variations in diet composition were influenced by changes in zooplankton prey availability across seasons and estuarine habitats. Mudflats were identified as the main foraging sites for juvenile fishes, while fringe mangrove had a weak influence on certain filter-feeder species. Understanding the dynamics of prey resources in estuarine habitats is critical for conservation efforts.

Summary: This study introduces the CART-GAMs model to effectively evaluate the suitability of benthic macroinvertebrates in estuarine habitats. The model removes data redundancy using the CART model, quantifies the nonlinear relationships between critical habitat factors and species using the GAM model, and determines suitable critical habitat factor ranges based on the response curves fitted by the GAM model.

Summary: The movement responses of juvenile fishes exposed to intermittent hypoxia mediate the effects of impaired water quality on estuarine nursery habitat function. The study found that the swimming speed of juvenile fishes increased nearly ninefold under hypoxic conditions, and they moved long distances in waters with low dissolved oxygen for up to 35 hours before finding refuge in shallow, oxygenated habitats. The study also revealed significant correlations between swimming speed and dissolved oxygen concentration, depth, and speed during the previous movement segment.

Summary: Exploring suitable ecological niche environments for endangered species is crucial for maintaining biodiversity. Black-necked Cranes are considered an indicator species in the alpine wetland ecosystem and are vulnerable according to IUCN. This study analyzed land cover patterns and habitat suitability of Black-necked Cranes breeding sites using remote sensing data and GIS technology. The results show changes in land cover, increasing fragmentation, and significant positive spatial autocorrelation for habitat suitability. Climate factors, particularly precipitation and temperature, play a significant role in determining the breeding habitat of Black-necked Cranes.

Summary: The study examined the gut microbiota of juvenile black sea bream in different habitats and found significant differences between wild and cultured populations. The gut microbiota was closely connected to diet, water, and sediment compartments, with environmental factors influencing the microbial composition in different habitats. The research enhances understanding of the interaction between gut microbiota and environmental factors, potentially aiding in the management of fish ecological fitness and stock enhancement programs.

Summary: Studies have shown significant genetic heterogeneity among Black Drum sampled from multiple estuaries in Texas, with regional groupings in the northern, central, and southern areas. Weak but significant genetic structure was also found among adjacent secondary estuaries within the Baffin Bay complex.

Summary: The Black Drum is a fish that supports recreational and commercial fisheries and shows high haplotype diversity but low nucleotide diversity. Research indicates that managing Black Drum as two stocks may be beneficial: one in the western Gulf of Mexico and the other in the Atlantic Ocean and eastern Gulf of Mexico.

Summary: This study examined the relationship between carapace width (CW) and carapace length (CL) for male and female blue crabs and the retention rates across a range of CWs for different escape ring sizes. The results showed that males have a greater CL at a given CW than females, and this difference increases with larger CWs. The study also found that increasing escape ring sizes resulted in increased carapace width at 50% retention, with a larger discrepancy between males and females.

Summary: In this study, the authors examined the population demographics of white and brown shrimp over a 36-year period in Texas estuarine and nearshore waters. The analysis showed consistent negative trends in mean length for brown shrimp, potentially due to exceeding the optimal growth range in summer water temperatures. The implications of these findings on population fecundity and shrimp harvest efficiency in commercial fisheries should be further investigated.

Summary: The Spotted Seatrout is a common predator in the Gulf of Mexico and a popular game fish in Texas. The study found regional and temporal variation in the species' growth and mortality, including sexual dimorphism with females growing faster and bigger than males, faster growth in northern estuaries, and higher mortality in northern estuaries. These findings suggest a complex demographic structure and the presence of independent subpopulations in the western Gulf of Mexico.
