Mother-Young Recognition In An Ungulate Hider Species: A Unidirectional Proce, Marco V.G. Torriani, Elisabetta Vannoni, Alan G. Mcelligott Sep 2006

Mother-Young Recognition In An Ungulate Hider Species: A Unidirectional Proce, Marco V.G. Torriani, Elisabetta Vannoni, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Parent‐offspring recognition is usually crucial for survival of young. In mammals, olfaction often only permits identification at short range, and vocalizations are important at longer distances. Following and hiding antipredator strategies found in newborn mammals may also affect parental recognition mechanisms. We investigated mother‐offspring recognition in fallow deer, an ungulate hider species. We analyzed the structure of adult female and fawn contact calls to determine whether they are individually distinctive and tested for mother‐offspring recognition. Only females (and not fawns) have individualized vocalizations, with the fundamental frequency as the most distinctive parameter. Playback experiments showed that fawns can distinguish the …

Anadromous Rainbow Smelt And Tomcod In Connecticut: Assessment Of Populations, Conservation Status, And Need For Restoration Plan, Heather A. Fried, Eric T. Schultz Jun 2006

Anadromous Rainbow Smelt And Tomcod In Connecticut: Assessment Of Populations, Conservation Status, And Need For Restoration Plan, Heather A. Fried, Eric T. Schultz

EEB Articles

(beginning of rainbow smelt executive summary)

Evidence indicates that anadromous rainbow smelt (Osmerus mordax) populations in Connecticut and elsewhere in the northeast United States have severely declined. Several sampling programs have documented declines in Connecticut’s smelt populations over the last three decades (Marcy 1976a, Marcy 1976b, Millstone Environmental Laboratory 2005). Similar declines have also been documented in the Hudson River (ASA Analysis & Communication 2005) and in Massachusetts (personal communication, Brad Chase, MA Division of Marine Fisheries 2004). Recreational and commercial fisheries in the region for this species have virtually ceased (Blake and Smith 1984). The Connecticut Fish Advisory Committee …


Substituting Otoliths For Chemical Analyses: Does Sagitta = Lapillus?, Nathan G. Smith, Cynthia M. Jones May 2006

Substituting Otoliths For Chemical Analyses: Does Sagitta = Lapillus?, Nathan G. Smith, Cynthia M. Jones

OES Faculty Publications

Chemical analysis of fish otoliths has become an important technique in fisheries science with widespread applications. Most research up to this point has focused predominantly on sagittal otoliths, but the underlying assumptions may also apply to lapilli. The goal of this study was to determine whether lapilli and sagittae have the same otolith chemistry and whether one can be substituted for the other for solution-based chemical analysis in wild-captured fish. We compared the stable isotope chemistry (δ13C and δ18O) of paired sagittae and lapilli of juvenile spotted seatrout Cynoscion nebulosus collected from Chesapeake Bay seagrass beds in 2002. …


Assessment Of Anadromous Alewife And Blueback Herring Populations In Connecticut Coastal Streams And Connecticut River Tributaries, Justin P. Davis, Eric T. Schultz Jan 2006

Assessment Of Anadromous Alewife And Blueback Herring Populations In Connecticut Coastal Streams And Connecticut River Tributaries, Justin P. Davis, Eric T. Schultz

EEB Articles

Alewife (Alosa pseudoharengus) and blueback herring (A. aestivalis) occur in anadromous populations that have a largely overlapping distribution from Florida to Newfoundland (Loesch 1987). Anadromous populations of these species are commonly collectively referred to as “river herring”. Adults inhabit coastal shelf waters until sexual maturity is reached at age 3-5 (Neves 1981). Sexually mature individuals make spawning migrations, commonly referred to as “runs”, into freshwater systems during spring months (Loesch 1987). Spawners can survive and return to spawn in subsequent years (Mullen et al. 1986). Juveniles reside in freshwater for 3-7 months, at which time they undertake a gradual migration …


The Natural History And Thermal Ecology Of A Population Of Spotted Turtles (Clemmys Guttata) And Wood Turtles (Glyptemys Insculpta) In West Virginia, Ariana N. Breisch Jan 2006

The Natural History And Thermal Ecology Of A Population Of Spotted Turtles (Clemmys Guttata) And Wood Turtles (Glyptemys Insculpta) In West Virginia, Ariana N. Breisch

Theses, Dissertations and Capstones

An ecological study was conducted from 19 March 2001 to 2 April 2003 on a population of Spotted Turtles (Clemmys guttata) and Wood Turtles (Glyptemys insculpta) in West Virginia. Live-trapping, mark-recapture, radio telemetry and temperature data logging techniques were used to gather information on morphometrics, capture success, movements, home range, behavior, and thermal regime during activity and over-wintering seasons. Twenty-one Spotted Turtles were captured 260 times. Population structure was 42.9% juvenile, 38.1% male, and 19.0% female. Mean home range was 0.52 ha. Fifty Wood Turtles were captured 230 times. Juveniles were 36%, and males and females were 32% each. Mean …


An Analysis Of Trap And Translocation Of White-Tailed Deer (Odocoleus Virginianus) Within The Enclosed Park Area Of Duke Farms, Hillsborough, New Jersey, December 2000 To March 2003, Christopher D. Aquila Jan 2006

An Analysis Of Trap And Translocation Of White-Tailed Deer (Odocoleus Virginianus) Within The Enclosed Park Area Of Duke Farms, Hillsborough, New Jersey, December 2000 To March 2003, Christopher D. Aquila

Theses, Dissertations and Culminating Projects

Translocation to manage overabundant wildlife populations, (in particularly Odocoileus spp.), is generally viewed as an acceptable method of wildlife removal where more aggressive methods (i.e. hunting, sharp shooting) are not considered viable options, in heavily developed urban areas and residential subdivisions.

From December 2000 to March 2003,1 conducted a large scale White-tailed Deer 0Odocoileus virginianus) translocation study on a 259 ha (640 acres) site at Duke Farms m Hillsborough, New Jersey, a location with high public visitation, over 100 employees, and a significant building infrastructure. Subsequently at the time of the study, the site was not conducive to any of …
