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. -

Hox Gene Expression During Development of the Phoronid Phoronopsis Harmeri Ludwik Gąsiorowski1,2 and Andreas Hejnol1,2*
Gąsiorowski and Hejnol EvoDevo (2020) 11:2 https://doi.org/10.1186/s13227-020-0148-z EvoDevo RESEARCH Open Access Hox gene expression during development of the phoronid Phoronopsis harmeri Ludwik Gąsiorowski1,2 and Andreas Hejnol1,2* Abstract Background: Phoronida is a small group of marine worm-like suspension feeders, which together with brachiopods and bryozoans form the clade Lophophorata. Although their development is well studied on the morphological level, data regarding gene expression during this process are scarce and restricted to the analysis of relatively few transcrip- tion factors. Here, we present a description of the expression patterns of Hox genes during the embryonic and larval development of the phoronid Phoronopsis harmeri. Results: We identifed sequences of eight Hox genes in the transcriptome of Ph. harmeri and determined their expression pattern during embryonic and larval development using whole mount in situ hybridization. We found that none of the Hox genes is expressed during embryonic development. Instead their expression is initiated in the later developmental stages, when the larval body is already formed. In the investigated initial larval stages the Hox genes are expressed in the non-collinear manner in the posterior body of the larvae: in the telotroch and the structures that represent rudiments of the adult worm. Additionally, we found that certain head-specifc transcription factors are expressed in the oral hood, apical organ, preoral coelom, digestive system and developing larval tentacles, anterior to the Hox-expressing territories. Conclusions: The lack of Hox gene expression during early development of Ph. harmeri indicates that the larval body develops without positional information from the Hox patterning system. -

Thus, the Iberian Peninsula and the surrounding islands represent a privileged area as regards the phoronids because from the 10 valid described phoronid species, only Phoronis ijimai has not been recorded (species presently restricted to the Pacific and NW Atlantic), while P. ovalis has been cited on the French Mediterranean coast near the Spanish border.

Publication of this fifth volume in the Tranche 2 Action Plan series fulfils the undertaking, given in the Government Response to the UK Biodiversity Action Plan Steering Group Report 1995, to produce maritime action plans covering further coastal and marine habitats and species. The volume includes reprints of the marine and coastal species and habitat action plans originall y published in the Steering Group’s Report, as well as new action plans for 16 species/groups of species and 17 habitats. The reprinted saline lagoon habitat action plan has an additional annex containin g statements on a further eight species whose conservation needs will be considered as part of that plan. Similarly, there are two species statements attached to the mud in deep habitats plan. -
