Temporal Dynamics of Eastern Oyster Larval Abundance in Great Bay Estuary, New Hampshire

Published in Journal of Shellfish Research, 2022

Eastern oyster Crassostrea virginica populations have been declining steadily over the past several decades across the North American East coast. The Great Bay Estuary (GBE), located in New Hampshire, is experiencing this loss and restoration efforts have been put into effect. This paper characterizes larval abundances of settled spat and two early stages of C. virginica, D-hinge and veliger, in GBE from 2018 to 2020.

Evaluating Connectivity of Coastal Marine Habitats in the Gulf of Maine by Integrating Passive Acoustics and Metabarcoding

Published in Oceanography, 2023

Ecological connectivity among coastal marine habitats—linkage in the movement of organisms and natural processes across habitat boundaries—has significant implications for the health and resilience of commercially important or threatened species in the Gulf of Maine (GOM), off the coast of the northeastern United States. Paired use of passive acoustic monitoring (PAM) and metabarcoding seawater samples (MSS) for observing biological and functional connectivity at various spatiotemporal scales in the marine environment is largely unexplored and may provide an efficient alternative or supplement to existing strategies.

First Documentation of Mating Blue Crabs, Callinectes sapidus, in Great Bay Estuary, New Hampshire

Published in Northeastern Naturalist, 2023

On 2 September and 7 October 2022, we captured post-copulatory pairs of Callinectes sapidus (Blue Crab) in Green Crab traps in Great Bay Estuary, NH. is the first scientific reporting of Blue Crabs mating in Great Bay Estuary, NH, documenting an ongoing range expansion of a species with the potential to have major ecological and economic impacts.

Using the Soundscape Code to compare coastal marine habitats in the Gulf of Maine

Published in The Journal of the Acoustical Society of America, 2023

Identifying similarities and differences in soundscape properties among coastal marine habitats is valuable for determining indicators of habitat composition, assessing functional connectivity among habitats, and informing management decisions regarding the soundscapes of these habitats. The objective of the current work was to determine whether geographic region or habitat type accounts for more variability in coastal soundscape properties.

Haplosporidium nelsoni and Perkinsus marinus occurrence in waters of Great Bay Estuary, New Hampshire

Published in Diseases of Aquatic Organisms, 2024

In Great Bay Estuary, New Hampshire, USA, Haplosporidium nelsoni and Perkinsus marinus are 2 active pathogens of the eastern oyster Crassostrea virginica (Gmelin), that cause MSX (multinucleated sphere with unknown affinity ‘X’) and dermo mortalities, respectively. Whereas studies have quantified infection intensities in oyster populations and determined whether these parasites exist in certain planktonic organisms, no studies thus far have examined both infectious agents simultaneously in water associated with areas that do and do not have oyster populations.

Abundance, Sex and Size Distribution of European Green Crabs, Carcinus maenas (Linnaeus, 1785), at Natural and Aquacultured Oyster Areas in Great Bay Estuary, NH

Published in Aquaculture, Fish, & Fisheries, 2024

Great Bay Estuary (GBE) is a complex estuarine system at the convergence of seven rivers, ocean and land. The GBE ecosystem supports typical estuarine species but, like many estuaries, has been a target of both invasive and range-expanding species. The goal of this study was to compare abundance, sex and size distribution of green crabs between oyster farm sites and non-farmed sites within GBE in 2021 and 2022.

Population genomics of eastern oysters, Crassostrea virginica, in a well-mixed estuarine system: advancement and implications for restoration strategies

Published in BMC Genomics, 2024

Eastern oysters, Crassostrea virginica, are historically a keystone species in many of the estuaries in which they reside, providing critical ecosystem services. Because oyster populations have been on the decline for the past century, restoration initiatives currently are underway in many estuarine systems, including Great Bay Estuary (GBE), New Hampshire. This study aimed to identify the population genomic structure of eastern oysters in GBE to facilitate determination of effective population size and estimation of genetic differentiation among subpopulations.

Diet of the blue crab (Callinectes sapidus) during range expansion in Great Bay Estuary, New Hampshire

Published in BMC Genomics, 2024

Great Bay Estuary (GBE), within the rapidly warming Gulf of Maine, has experienced significant ecological shifts this century due to naturalization of invasive species. The range expansion of the American blue crab (Callinectes sapidus) currently underway from the mid-Atlantic northward brings the possibility of similar ecological shifts. This study accounts recent trapping and diet analysis of C. sapidus in GBE.
