The Fine-Scale Habitat Use Of Risso’S Dolphins Off Bardsey Island, Cardigan Bay (Uk), Marijke N. De Boer, Sonja Eisfeld, Mark P. Simmonds
Mark P. Simmonds, OBE
The main objectives of this study were (1) to estimate the population size of Risso’s dolphins off Bardsey Island using mark-recapture techniques (De Boer et al., 2013); and (2) to study habitat-use in relation to fine-scale oceanographic features. This work provides preliminary information on the habitat-use of Risso’s dolphins and will benefit future studies, along with the development of effective conservation measures for this species throughout the region.
Cercyonis Pegala Agawamensis (Satyridae): A New Butterfly Subspecies From The Coastal Salt Marshes Of The Northeastern United States Of America, Matthew D. Arey, Alex Grkovich
Cercyonis Pegala Agawamensis (Satyridae): A New Butterfly Subspecies From The Coastal Salt Marshes Of The Northeastern United States Of America, Matthew D. Arey, Alex Grkovich
The Taxonomic Report of the International Lepidoptera Survey
A new subspecies of the Common Wood Nymph (Cercyonis pegala) from the New England coastline in the northeastern region of the United States is described on the basis of phenotype, behavior, habitat, seasonality, flight period, and phenology. Agawamensis is univoltine as in all pegala. The newly described subspecies occurs almost entirely in coastal salt marshes and estuarine meadows, quite atypical as understood for Cercyonis pegala. The newly described subspecies agawamensis predominately prefers and occurs within large open salt marshes but can also be found in similar habitat along smaller tidal rivers, coastal inlets and streams
Larval Host Plants Of Enodia Anthedon, Satyrodes Appalachia And S. Eurydice In Vermont, Usa, David J. Hoag
Larval Host Plants Of Enodia Anthedon, Satyrodes Appalachia And S. Eurydice In Vermont, Usa, David J. Hoag
The Taxonomic Report of the International Lepidoptera Survey
Field observation and captive rearing was used to clarify larval host plant use in Enodia anthedon, Satyrodes appalachia, and S. eurydice in Vermont, USA. In nature S. appalachia larvae were found on Carex lacustris, C. lupulina, C. gracillima, and C. tuckermanii. Enodia anthedon in nature was found to oviposit on grass and on Carex lacustris. Larvae of E. anthedon were found on C. lacustris and C. lupulina. In captivity, all but two E. anthedon larvae chose Carex over grass. Both E. appalachia and E. anthedon …
Spatial And Habitat Responses Of Canada Lynx In Maine To A Decline In Snowshoe Hare Density, David G. Mallett
Spatial And Habitat Responses Of Canada Lynx In Maine To A Decline In Snowshoe Hare Density, David G. Mallett
Electronic Theses and Dissertations
Previous studies of Canada lynx (Lynx canadensis) within the northern boreal forest region have documented that lynx respond spatially to a decline in snowshoe hare (Lepus americanus) density, as exhibited by expansion of territories and changes in social structure. I compared home range area and spatial overlap in the southeastern portion of their geographic range during periods of relatively high and relatively low hare density. Home range areas of lynx did not change between periods of high and low hare density, except that home ranges of females during the denning season expanded during the low period. The presence of kittens …
