Comparative Study Of Spinning Field Development In Two Species Of Araneophagic Spiders (Araneae, Mimetidae, Australomimetus), Mark A. Townley, Danilo Harms
Comparative Study Of Spinning Field Development In Two Species Of Araneophagic Spiders (Araneae, Mimetidae, Australomimetus), Mark A. Townley, Danilo Harms
Molecular, Cellular & Biomedical Sciences
External studies of spider spinning fields allow us to make inferences about internal silk gland biology, including what happens to silk glands when the spider molts. Such studies often focus on adults, but juveniles can provide additional insight on spinning apparatus development and character polarity. Here we document and describe spinning fields at all stadia in two species of pirate spider (Mimetidae: Australomimetus spinosus, A. djuka). Pirate spiders nest within the ecribellate orb-building spiders (Araneoidea), but are vagrant, araneophagic members that do not build prey-capture webs. Correspondingly, they lack aggregate and flagelliform silk glands (AG, FL), specialized for forming prey-capture …
Review Of Seagrassnet Monitoring Photographs In Great Bay, New Hampshire, Usa 2007 - 2014, Frederick T. Short
Review Of Seagrassnet Monitoring Photographs In Great Bay, New Hampshire, Usa 2007 - 2014, Frederick T. Short
PREP Reports & Publications
SeagrassNet is a global monitoring program begun in 2001 and designed to scientifically detect and document seagrass habitat change (Short et al. 2006a, 2014). Monitoring of eelgrass (Zostera marina L.) in the Great Bay Estuary using SeagrassNet was conducted in Portsmouth Harbor between 2001 and 2009 (Short et al 2006b, Rivers and Short 2007), and is ongoing in Great Bay itself, from 2007 (Short 2009) to the present. In this report, July quadrat photos taken along the three Great Bay SeagrassNet transects from 2007 – 2014 are presented and discussed. They provide useful documentation of field percent cover measurements of …
2016 Oyster Reef Restoration Project Funded By The Aquatic Resources Mitigation Program, Raymond E. Grizzle, Krystin M. Ward
2016 Oyster Reef Restoration Project Funded By The Aquatic Resources Mitigation Program, Raymond E. Grizzle, Krystin M. Ward
PREP Reports & Publications
This report describes the results of the construction and initial monitoring phase of an oyster restoration project conducted in 2016 by the University of New Hampshire (UNH) and The Nature Conservancy (TNC), funded by the New Hampshire Aquatic Resources Mitigation Program. The overall goal of the project was to construct 5 acres of new oyster reef habitat in an area adjacent to a live natural reef northwest of Nannie Island, in the Town of Newington, NH, off Woodman Point. The report is organized according to the four major tasks listed as deliverables in the subaward to UNH from TNC.

SeagrassNet is a global monitoring program begun in 2001 and designed to scientifically detect and document seagrass habitat change (Short et al. 2006a, 2014). Monitoring of eelgrass (Zostera marina L.) in the Great Bay Estuary using SeagrassNet was conducted in Portsmouth Harbor between 2001 and 2009 (Short et al. 2006b, Rivers and Short 2007), and in Great Bay starting in 2007 (Short 2009). Results from SeagrassNet 2015, supported by PREP and conducted in Great Bay, are described in this report.
Eelgrass Distribution In The Great Bay Estuary And Piscataqua River For 2016, Seth Barker
Eelgrass Distribution In The Great Bay Estuary And Piscataqua River For 2016, Seth Barker
PREP Reports & Publications
Eelgrass distribution in Great Bay, Little Bay, and the Piscataqua River Estuary were mapped from aerial photography acquired on August 5, 2016. The total area of eelgrass beds with 10% or greater cover and a polygon area equal to or greater than 100 square meters was 683.42 hectares or 1688.71 acres. Eelgrass polygons were coded for Assessment Zone location and the results reported in Table 1.The largest concentration of eelgrass was found in Great Bay with lesser amounts in the vicinity of Portsmouth Harbor. The total area of eelgrass was nearly identical to that mapped in 2013 though there were …
Testing Of Great Bay Oysters For Two Protozoan Pathogens, Douglas E. Grout
Testing Of Great Bay Oysters For Two Protozoan Pathogens, Douglas E. Grout
PREP Reports & Publications
Two protozoan pathogens, Haplosporidium nelsoni (MSX) and Perkinsus marinus (Dermo) are known to be present in Great Bay oysters. With funds provided by the Piscataqua Region Estuaries Partnership (PREP), the Marine Fisheries Division of the New Hampshire Fish and Game Department (NHFG) continues to assess the presence and intensity of both of these disease conditions in oysters from the major natural beds within the Great Bay estuarine system. Histological examinations of Great Bay oysters have also revealed other endoparasites
Monitoring Macroalgae In The Great Bay Estuary For 2015, David M. Burdick, Arthur C. Mathieson, Sydney Nick, Christopher R. Peter
Monitoring Macroalgae In The Great Bay Estuary For 2015, David M. Burdick, Arthur C. Mathieson, Sydney Nick, Christopher R. Peter
PREP Reports & Publications
In 2015, five of the eight locations with fixed intertidal transects were sampled as part of the long-term effort to monitor macroalgae in the Great Bay Estuary. With the completion of the third year of the project, all eight locations have been sampled at least once, two years of data have been collected for four locations, and three years of data have been collected for one location, Monitoring results from 2015 show high levels of cover of nuisance green or red algae (Ulva and Gracilaria, respectively) at all sites sampled. Nuisance algae is characterized as fast-growing; it can interfere with …
The Relationship Of Life Stage To Daily Social Patterns Of Captive African Elephants (Loxodonta Africana) And The Correlation Of Handler Perceptions Of Elephant Personality To Demonstrated Social Behaviors, Alison Jeffrey
Honors Theses and Capstones
Elephants typically have very strong social bonds, and social interactions can include affiliative, agonistic, or ambiguous behaviors. The social interactions and dominance hierarchy between individuals of a herd depend upon many factors, including maternal lineage, age, and sex. This study was designed to determine how social behaviors among a herd of captive African elephants varied throughout the day and to establish if the frequency of social interactions and age class were correlated. The study also aimed to determine if handler perceptions of elephant personality were an accurate predictor of the type and frequency of social behaviors observed, in addition to …
Daily Distance Moved And Home Range Analysis Of Female Cheetahs On Namibia's Commercial Farmland, Elisabeth Nicole Wise
Daily Distance Moved And Home Range Analysis Of Female Cheetahs On Namibia's Commercial Farmland, Elisabeth Nicole Wise
Honors Theses and Capstones
Fewer then 10,000 cheetahs remain in Sub-Saharan Africa. Namibia has the largest population, estimated to be 4,000. Habitat fragmentation and prey depletion from human expansion for agriculture has pushed 90% of cheetahs to reside on commercial farmland where there is an absence of larger predators. Radio telemetry was used to investigate the seasonal variation in home range size among nine female cheetahs on commercial farmlands on or near the Cheetah Conservation Fund in Otjiwarongo, Namibia. ArcGIS 10.3 and Geospatial Modeling Environment were used to calculate the overall and core home range size. This was estimated for the overall, annual, monthly, …
