Benthic Invertebrate Community Monitoring and Indicator Development for Barnegat Bay-Little Egg Harbor Estuary
July 15, 2013 Final Report Project SR12-002: Benthic Invertebrate Community Monitoring and Indicator Development for Barnegat Bay-Little Egg Harbor Estuary Gary L. Taghon, Rutgers University, Project Manager [email protected] Judith P. Grassle, Rutgers University, Co-Manager [email protected] Charlotte M. Fuller, Rutgers University, Co-Manager [email protected] Rosemarie F. Petrecca, Rutgers University, Co-Manager and Quality Assurance Officer [email protected] Patricia Ramey, Senckenberg Research Institute and Natural History Museum, Frankfurt Germany, Co-Manager [email protected] Thomas Belton, NJDEP Project Manager and NJDEP Research Coordinator [email protected] Marc Ferko, NJDEP Quality Assurance Officer [email protected] Bob Schuster, NJDEP Bureau of Marine Water Monitoring [email protected] Introduction The Barnegat Bay ecosystem is potentially under stress from human impacts, which have increased over the past several decades. Benthic macroinvertebrates are commonly included in studies to monitor the effects of human and natural stresses on marine and estuarine ecosystems. There are several reasons for this. Macroinvertebrates (here defined as animals retained on a 0.5-mm mesh sieve) are abundant in most coastal and estuarine sediments, typically on the order of 103 to 104 per meter squared. Benthic communities are typically composed of many taxa from different phyla, and quantitative measures of community diversity (e.g., Rosenberg et al. 2004) and the relative abundance of animals with different feeding behaviors (e.g., Weisberg et al. 1997, Pelletier et al. 2010), can be used to evaluate ecosystem health. Because most benthic invertebrates are sedentary as adults, they function as integrators, over periods of months to years, of the properties of their environment. -

Impact of the the COVID-19 Pandemic on a Queen Conch (Aliger Gigas) Fishery in the Bahamas
Impact of the the COVID-19 pandemic on a queen conch (Aliger gigas) fishery in The Bahamas Nicholas D. Higgs Cape Eleuthera Institute, Rock Sound, Eleuthera, Bahamas ABSTRACT The onset of the coronavirus (COVID-19) pandemic in early 2020 led to a dramatic rise in unemployment and fears about food-security throughout the Caribbean region. Subsistence fisheries were one of the few activities permitted during emergency lockdown in The Bahamas, leading many to turn to the sea for food. Detailed monitoring of a small-scale subsistence fishery for queen conch was undertaken during the implementation of coronavirus emergency control measures over a period of twelve weeks. Weekly landings data showed a surge in fishing during the first three weeks where landings were 3.4 times higher than subsequent weeks. Overall 90% of the catch was below the minimum legal-size threshold and individual yield declined by 22% during the lockdown period. This study highlights the role of small-scale fisheries as a `natural insurance' against socio-economic shocks and a source of resilience for small island communities at times of crisis. It also underscores the risks to food security and long- term sustainability of fishery stocks posed by overexploitation of natural resources.

This chordate subphylum contains a particularly diverse range of reproductive 21 methods, regenerative abilities and life-history strategies. Consequently, tunicates provide an 22 extraordinary perspective into the emergence and diversity of chordate traits. Currently 23 published tunicate genomes include three Phlebobranchiae, one Thaliacean, one Larvacean 24 and one Stolidobranchian. To gain further insights into the evolution of the tunicate phylum, 25 we have sequenced the genome of the colonial Stolidobranchian Botrylloides leachii. -

Colonies are uniformly colored, but can vary from purple, red, yellow, orange and brown. It species is native to the Northwest Pacific, but has been introduced on both coasts of North America, and parts of Atlantic Europe. It is a common fouling organism throughout much of its introduced range, where it often displaces and competes with other native and non-native fouling organisms, including tunicates, bryozoans, barnacles, and mussels.
