Seagrass Deterrence To Mesograzer Herbivory: Evidence From Mesocosm Experiments And Feeding Preference Trials, Latina Steele, John F. Valentine Mar 2015

Seagrass Deterrence To Mesograzer Herbivory: Evidence From Mesocosm Experiments And Feeding Preference Trials, Latina Steele, John F. Valentine

Biology Faculty Publications

Two laboratory experiments documented the effects of mesograzers (i.e. the gastropod Crepidula ustulatulina and the isopod Paracerceis caudata) on phenolic acid and condensed tannin production in 2 regionally abundant seagrasses—Thalassia testudinum (turtlegrass) and Halodule wrightii (shoalgrass). Subsequent paired choice experiments tested the hypothesis that phenolic acids and condensed tannins produced by these seagrasses deter mesograzer feeding. At the scale of the shoot, grazing by gastropods and isopods led to ~40 to 50% decreases in concentrations of some phenolic acids and ~20% decreases in condensed tannins in turtlegrass leaves. At a more refined spatial scale, concentrations of 2 of ...


Ship-Induced Solitary Riemann Waves Of Depression In Venice Lagoon, Kevin E. Parnall, Tarmo Soomere, Luca Zaggia, Artem Rodin, Giuliano Lorenzetti, John Rapaglia, Gian Marco Scarpaf Mar 2015

Ship-Induced Solitary Riemann Waves Of Depression In Venice Lagoon, Kevin E. Parnall, Tarmo Soomere, Luca Zaggia, Artem Rodin, Giuliano Lorenzetti, John Rapaglia, Gian Marco Scarpaf

We demonstrate that ships of moderate size, sailing at low depth Froude numbers (0.37–0.5) in a navigation channel surrounded by shallow banks, produce depressions with depths up to 2.5 m. These depressions (Bernoulli wakes) propagate as long-living strongly nonlinear solitary Riemann waves of depression substantial distances into Venice Lagoon. They gradually become strongly asymmetric with the rear of the depression becoming extremely steep, similar to a bore. As they are dynamically similar, air pressure fluctuations moving over variable-depth coastal areas could generate meteorological tsunamis with a leading depression wave followed by a devastating bore-like feature.


The Mismanagement Of Limulus Polyphemus In Long Island Sound, U.S.A.: What Are The Characteristics Of A Population In Decline?, Mark Beekey, Jennifer Mattei Jan 2015

Over the past 15 years, horseshoe crabs in Connecticut have gone from being considered a nuisance species to a species of Greatest Conservation Need in 2015. This has happened through first, its discovery as an economically important species, second through research of its ecological role in coastal estuaries, and third, through education of the public concerning its role in the environment and their own health. To manage horseshoe crab populations successfully requires long term monitoring, research and education. The use of annual or biannual trawl data trends to assess the success of management decisions is limited due to the high ...


Horseshoe Crab Research In Urban Estuaries: Challenges And Opportunities, Jennifer Mattei, Mark L. Botton, Mark Beekey, Christina P. ColóN Jan 2015

Horseshoe Crab Research In Urban Estuaries: Challenges And Opportunities, Jennifer Mattei, Mark L. Botton, Mark Beekey, Christina P. ColóN

Horseshoe crabs rely on estuaries for food resources, places to spawn and for larvae and juveniles to develop and grow. Many of these estuaries are becoming increasingly urbanized and dominated by human activity. An urban estuary is characterized by armored shorelines, high nutrient loads, large fluctuations in algal and bacteria populations, increased levels of pollutants like heavy metals and pesticides, and seasonally low oxygen levels and pH. While urban estuaries are challenging for horseshoe crab survival and to researchers trying to study them, there are also opportunities for involving the public in research and increasing public awareness of the importance ...
