Recovery Tool for Enhanced Black Abalone Recruitment on the California Channel Islands and Coastal Habitat (Legacy 12-635) (PDF)
In 2009, California (CA) State and Federal agencies declared the black abalone (Haliotis cracherodii), a marine gastropod mollusk, endangered under the Endangered Species Act. H. cracherodii ranges from northern CA to Baja CA, Mexico and occurs in rocky intertidal habitats to about 6 m depth. This accessibility exposes them to anthropogenic pressures from human harvesting, habitat destruction, and pollution more than other CA abalone species. In the wild, fertilization and recruitment rates of H. cracherodii are currently critically low due to the low density of reproductive adults, making it difficult for populations to recover from pressures such as Withering Foot Syndrome (WFS) and human harvesting (Chambers et al. 2006). Restoring wild populations therefore, is crucial, and the recovery of this endangered species may require human intervention.
Determining Marine Migration Patterns and Behavior of Gulf Sturgeon in the Gulf of Mexico off Eglin Air Force Base, Florida - Final Report, January 2012 (Legacy 10-428) (PDF)
This report is a compilation of data and information covering three years of monitoring and significantly expands on knowledge of the spatial and temporal distribution of Gulf sturgeon. Prior to this project it was not known where Gulf sturgeon traveled during the winter months in the Gulf of Mexico. The results of this study provide an abundance of data and analyses that can be utilized for Endangered Species Act (ESA) Section 7 consultations, National Environmental Policy Act (NEPA), and a multitude of other environmental management applications. These findings are not only applicable to Eglin Air Force Base (AFB), but may also benefit other DoD installations around the Gulf Coast such as Tyndall AFB, Naval Air Station Pensacola, Naval Station Pascagoula, and Keesler AFB.
Determining Marine Migration Patterns and Behavior of Gulf Sturgeon in the Gulf of Mexico off of Eglin Air Force Base - Technical Report September 2010 (Legacy 09-428) (PDF)
This project was to utilize acoustic tracking technology to elucidate Gulf sturgeon behavior in the Gulf of Mexico critical habitat of Northwest Florida. The combined efforts of the 2008 Pilot Study and the 2009 Legacy Study have allowed Eglin to determine Gulf sturgeon presence and movement patterns within critical habitat areas surrounding Eglin Air Force Base. Other important topics addressed in this report include movement patterns of Gulf sturgeon from different river systems, identification of potential hot spots within the Gulf of Mexico portion of the study area, river fidelity of the Gulf sturgeon in this sample, and level of performance of the acoustic technology utilized in this study in a harsh marine environment.
Propagation of Species At Risk Atlantic Pigtoe on Military Installations-Final Report April 2010 (Legacy 09-450) (PDF)
The Department of Army has identified the Atlantic Pigtoe Mussel as a Species at Risk (SAR) with potential for detrimental impact on the military mission if federally listed as either threatened or endangered. The Nottoway River on ARNG-MTC Fort Pickett, VA is home to one of only two known stable populations of the Atlantic Pigtoe Mussel left in Virginia, and perhaps the world. Populations are in precipitous decline throughout the southeast, and expert consensus is that the species currently warrants federal listing. This project details the first year's efforts towards propagating the species and introducing new populations into its habitat
Ecological Monitoring Compendium on Wake Island Prior to Rat Removal - Final Technical Report, November 2011 (Legacy 09-438) (PDF)
Introduced rats are known to dramatically affect island biodiversity. On Wake Island, a U.S. Air Force installation in the tropical Pacific, rats predate seabirds and may have extirpated several seabird species from the island. Rats may impact a range of other biota and ecological processes on Wake. The Wake Island eradication provides a valuable opportunity to document ecological changes on such an island by monitoring various taxa before and after the operation. This report contains a Work Plan, Monitoring Protocol, and Sampling Designs for Seabird Monitoring, Shorebird Monitoring, Sea Turtle Monitoring, Vegetation Sampling, Arthropod Sampling, and Rodent Population Monitoring on Wake Island. The protocols and results described in the above reports, if replicated post eradication, can provide valuable documentation of ecological changes on Wake Island resulting from rat removal. These documented changes can then be used to generate predictions about ecological responses to potential rat eradications on other tropical islands on which the Department of Defense (DoD) has a management stake.
Deployment of Acoustical Alert Devices on Select DoD Vessels to Mitigate the Risk of Vessel Collisions with Marine Mammals - Final Technical Report, September 2011 (Legacy 08-414) (PDF)
The West Indian manatee is an endangered marine mammal which inhabits the waterways of Department of Defense (DoD) installations in S.E. Georgia and peninsular Florida. Manatees are vulnerable to collisions with watercraft. In an effort to protect manatees The DoD Legacy Management Resource Program supported behavioral hearing and acoustic propagation studies that revealed manatees cannot adequately detect and locate the dominant lower frequency sounds of approaching vessels and slower speeds can actually increase the risks of collisions. These discoveries led to the development and successful field testing of an acoustic warning device designed to provide wild manatees with the sensory awareness to avoid collisions. This report details the development and testing of the alert system.
Conserving Integral Units of Chihuahuan Desert Biodiversity: Population Dynamics for Recently Introduced Populations of White Sands Pupfish - Preliminary Report, February 2006 (Legacy 05-112) (PDF)
The translocation of wild animals to establish or re-establish additional populations has become a common management strategy and yet such populations are rarely well monitored. This is especially critical during early establishment as such populations may experience un-documented demographic bottlenecks and a loss of genetic variation. Desert fish have been extensively translocated. The genetic effects of such transplants have been studied for various pupfish species however, replicated transplants have rarely been conducted offering an opportunity to evaluate the likelihood that such populations diverge from each other as well as from the source population. This report details the demographic data for 7 experimental populations of the White Sands pupfish (Cyprinodon tularosa).
Conserving Integral Units of Chihuahuan Desert Biodiversity: High Allelic Richness and Population Divergence for an Expressed Nuclear Gene in an Imperiled fish - Final Report, February 2006 (Legacy 05-112) (PDF)
Previous work on White Sands pupfish (Cyprinodon tularosa) using unexpressed genetic markers has shown that significant genetic differentiation exists between the two native populations located on the White Sands Missile Range in New Mexico. The two populations, which have been historically isolated, differ in parasite communities suggesting that functional differences may have evolved in immunity-related genes. This project sought to determine if the variation in studied immunity-related nuclear gene complex, the Major histocompatibility complex (Mhc) do have functional differences.
