Comprehensive Strategy for Reducing Maryland

Comprehensive Strategy for Reducing Maryland's Vulnerability to Climate Change, Phase II: building societal, economic, and ecological resilience

Boicourt KE and Johnson ZP (eds) ·
24 January 2011

This report details the findings of the Scientific and Technical Working Group, comprised of experts representing six sectors—human health, agriculture, forests and terrestrial ecosystems, bay and aquatic ecosystems, water resources, and population growth and infrastructure. Each sector assessed climate change vulnerabilities, and recommended adaptation strategies for the State of Maryland.

University of Maryland Center for Environmental Science: History, Mission & Accomplishments

Dave Nemazie, Bill Dennison, Tracey Saxby ·
1 February 2003

This newsletter is a summary of the history, mission and accomplishments of the University of Maryland Center for Environmental Science (UMCES). This summary has been prepared to provide a sense of where we have come from, what we are doing and where we are going. It also serves to identify the collaborative role UMCES plays within the University System and the State of Maryland.

Temperature, salinity and food effects on asexual reproduction and abundance of the scyphozoan Chrysaora quinquecirrha

Purcell JE, White JR, Nemazie DA, and Wright DA ·
1999

Outbreaks of jellyfish are reported worldwide, yet the environmental factors that control the sizes of jellyfish populations are not well understood. The scyphomedusan Chrysaora quinquecirrha occurs in the mesohaline portion of Chesapeake Bay each summer. Population sizes of the medusae show dramatic annual variations that are correlated with salinity and temperature.

Toward a national agenda for research in the coastal zone: Where are we?

Malone TC and Nemazie DA ·
1996

In response to the complex challenges of understanding and managing the effects of human activities on coastal ecosystems, the research establishment has produced a plethora of reports and implemented a bewildering array of government-sponsored research and monitoring programs that are not cost-effective on regional or national scales.

Predation Mortality of Bay Anchovy Anchoa-Mitchilli Eggs and Larvae Due to Scyphomedusae and Ctenophores in Chesapeake Bay

Purcell JE, Nemazie DA, Dorsey SE, Houde ED, and Gamble JC ·
1994

We measured predation on bay anchovy Anchoa mitchilli eggs and larvae by abundant scyphomedusae Chrysaora quinquecirrha and ctenophores Mnemiopsis leidyi from gut contents, digestion rates, and densities of predators and prey during 9 d in July 1991 at 4 stations in Chesapeake Bay, USA, These predation rates were compared to egg and larval mortality rates measured concurrently in ichthyoplankton surveys.

Ammonium Excretion by Gelatinous Zooplankton and Their Contribution to the Ammonium Requirements of Microplankton in Chesapeake Bay

Nemazie DA, Purcell JE, and Glibert PM ·
1993

Ammonium excretion rates of recently collected specimens of gelatinous zooplankton. the scyphomedusan Chrysaora quinquecirrha DeSor and the ctenophore Mnemiopsis leidyi A. Agassiz, were correlated with body mass and water temperature in measurements made from April to October 1989 and 1990. Rates ranged between 3.5 and 5.0 mug atoms NH4+-N (g dry wt)-1 h-1 for C. quinquecirrha and 3.0 to 4.9 mug atoms NH4-N (g dry wt) -1 h-1 for M. leidyi.

Quantitative Feeding Ecology of the Hydromedusan Nemopsis-Bachei in Chesapeake Bay

Purcell JE and Nemazie DA ·
1992

We determined feeding rates of the hydromedusan Nemopsis bachei L. Agassiz in the mesohaline region of Chesapeake Bay, USA during the spring of 1989 and 1990 from gut contents, digestion rates and abundances of medusae and zooplankton. The medusae consumed primarily copepodites of Acartia tonsa, selecting against naupliar stages.
