Forty-year Kinosternon angustipons (Central American mud turtle) Management Plan in Nicaragua

Thu, 04/30/2020 - 14:18
Abstract: Kinosternon angustipons (Central American/ narrow bridged mud turtle) is a mud turtle native to Nicaragua, Costa Rica, and Panama. There is limited primary scientific information available except for the initial species description. K. angustipons and other native turtles are threatened by illegal forestry activity, pollution, and invasive predators. Through the use of a population model, the projected population will decline until extinction within the next forty years. The model identified key areas of interest that, if properly managed, can result in healthy stable population. Three areas of management focus should be; improving the current scientific knowledge base for K. angustipons to focus and facilitate accurate management effort. Improving the habitat quality will increase availability and quality of cover and food resources. Finally, protecting the nest and hatchlings will increase survival and recruitment within the population. These actions should have the desired results of increasing the percentage of reproductively active females, average number of eggs, and the survivability of the nest and hatchlings. If these areas, determined by the model to be influential to the population's rate of change, receive targeted support then K. angustipons will not remain unknown or go extinct.

North Cascades Ecosystem Wolverine (Gulo gulo) Revival Plan

Thu, 04/30/2020 - 13:32
Abstract: Wolverines (Gulo gulo) are recognized as one of the rarest, and least known carnivores of the northern hemisphere. They are the largest bodied mustelid and survive primarily on carrion food subsidies while living at low population densities. Conservation issues of primary concern to the North Cascades wolverine population include human sensitivity, high management costs, lack of policy protection, and the impacts of climate change (i.e. genetic bottlenecking and lack of connectivity due to decreasing persistent snow cover). This management plan, in the form of a revival plan, seeks to increase the wolverine population within the North Cascades Ecosystem (NCE) to a more sustainable size. Objectives to reach this goal include conducting research to obtain a population size estimate within 3 years following the onset of the revival plan, increasing allelic richness of the population by 25% over the next 10 years, and maintaining the high survivorships at all wolverine age classes for 20 years. To maximize efficiency, while also minimizing cost, the population estimation will be conducted based on data collection from scatdetection dog teams and live-trapping wolverines with log-cabin style box traps. Due to the contingency of subsequent objectives, log-cabin live-trapping is also beneficial as it presents the opportunity to directly handle wolverines and deploy radio collars. To increase allelic richness of the wolverine population, individuals from the Greater Yellowstone Ecosystem in Montana will be translocated to supplement the gene pool. To ensure gene flow and promote connectivity within the population, habitat corridors will also be created utilizing living tree fences that promote snow accumulation and persistence that is favored for wolverine dispersal. To maintain survivorship rates (68% for juveniles, 92% for subadults, 91% for adults) actions taken will slightly increase survival, creating a buffer zone to prevent decreased survival at any age class. Specific actions include petitioning for state and/or federal protection under the Endangered Species Act to designate critical habitat and ultimately prevent disturbance and decreasing infanticidal mortality events utilizing a Radio Activated Guard (RAG) depredation deterrent system. Management actions will increase the population to a size that is accepted by stakeholders and financially feasible based on a habitat suitability model of the North Cascades Ecosystem.

Twenty-Year Management Plan for Northern Long-eared Bat (Myotis septentrionalis) populations in the United States

Thu, 04/30/2020 - 12:32
Abstract: Since the onset of white-nose syndrome in 2006, bat populations have been declining rapidly. For the northern long-eared bat, Myotis septentrionalis, this rate was as high as 75% in some years. With such high mortality it will not take long for the species to be extinct, modeling suggests it could be as soon as within the next 10 years (Appendix B). Unfortunately, white-nose syndrome is not the only issue M. septentrionalis face. They are a tree-roosting migratory bat which means they are highly impacted by windmills and their increasing construction. Bats are struck by the windmill blades, along with the impacts of habitat fragmentation that the windmill construction creates. It is important to implement a management for M. septentrionalis immediately because they provide important ecosystem services to the agriculture community. Northern long-eared bats eat crop pests which increases the yield on those crops, this ultimately leads to a reduction of pesticides farmers need to use and lower food prices. Northern long-eared bats combat more than just crop pests, they eat mosquitos too! Ultimately, if this management plan is executed successfully, northern long-eared bat populations will be restored and farmers will be able to reduce the amount of pesticide use and food prices will remain low.

Fifty-Year Mary River Turtle (Elusor macrurus) Management Plan for Eastern Australia

Thu, 04/30/2020 - 12:15
Abstract: Mary River turtles (Elusor macrurus) are environmental specialists and are endemic to the Mary River system in Queensland, Australia. They are highly dependent on cloacal respiration, and are capable of spending up to 72 hours underwater in a single dive. Mary River turtles are a long-lived species, typically not reaching sexual maturity until 30 years of age. Conservation issues for this species include the following: exploitation of nests for the pet trade, loss of habitat connectivity due to the creation of dams, predation of nests by mesopredators, and nest mortality due to inundation of nests by floodwaters. Climate change poses additional risks towards this species due to rising temperatures and increased duration of droughts. There are two goals for this management plan, they include: (1) to restore the Mary River turtle population in Queensland, Australia to sustainable levels, and (2) to restore connectivity of the Mary River system in Queensland, Australia to promote the interaction of the local people with Mary River turtles. In order to reach these goals, multiple objectives have been established, they include: (1a) increase Mary River turtle nest survival by 50% in the Tiaro region of Queensland, Australia over the next 10 years, (2a) increase the number of nesting female Mary River turtles to 50% of the female population over the next 25 years, (1b) increase connectivity of Mary River turtle habitat by 50% over the next 50 years, (2b) increase public support for Mary River turtle conservation by 50% over the next 10 years. Objective 1a will be reached by protecting existing Mary River turtle nesting sites from mesopredator predation. Objective 2a will promote the creation of suitable nesting habitat to attract additional female turtles to nest in a protected area. To satisfy goal 2, objective 1b will be reached by establishing a suitable flow regime for 50% of the dams along the Mary River, which will reduce hypoxic environments to support Mary River turtles. Objective 2b will be reached by educating the public about Mary River turtles, as well as involving the public with the implementation of the management plan through volunteer positions. By fulfilling the goals set forth in this management plan, it will allow for the formation of a long-term/successful Mary River turtle management plan.

Twenty-year Long-tailed duck (Clangula hyemalis) Management Plan for Eastern North America

Thu, 04/30/2020 - 11:44
Abstract: Long-tailed ducks (Clangula hyemalis) are a migratory sea duck with a circumpolar distribution. Since they are an arctic species and breed outside of current breeding bird surveys there is little data for their demographics and no data specific to eastern North America (Atlantic Flyway and Mississippi Flyway). Over the last 30 years their population has declined by 50%; this causes concern that the species could be at risk of becoming endangered if the trend in population numbers continues. This management plans goal is to increase and stabilize long-tailed ducks population numbers over the next 20 years. This will be accomplished by decreasing the bycatch of long-tailed ducks in commercial gillnet fisheries by 10% and reducing the total number harvested through hunting per year by 10%. To better monitor this progress a breeding bird survey will be established in their eastern North American breeding area. Surveys and alternative fishing methods will be introduced to commercial gillnet fisheries to raise awareness about bycatch of long-tailed ducks and seabirds in general. By the end of this 20 year management plan, it is expected that long-tailed ducks, along with seabirds and other arctic bird species breeding outside of current breeding bird surveys, will benefit from these actions.

Sun Bear (Helarctos malayanus) 20-year Management Plan for Lao People’s Democratic Republic

Tue, 04/28/2020 - 15:54
Abstract: Sun bears (Helarctos malayanus) are the smallest member of the Ursidae family and are native to large, undisturbed dipterocarp tropical forests in southeast Asia. They are omnivorous with a diet consisting primarily of fruit and insects. Sun bears are solitary and historically avoid areas with a strong human presence. These preferred areas are decreasing in abundance in Lao People’s Democratic Republic (PDR) as the nation’s economy grows with its timber industry, causing widespread deforestation. The lack of available forests for sun bears inhibits the ability of juveniles to disperse from their mother’s dens, decreasing their survivorship. Deforestation has also forced sun bears to live in closer proximity to humans, especially in agricultural areas. This causes interactions in the form of crop raiding and property damage, bringing economic harm to farmers in Lao PDR. These negative interactions have also caused farmers in Lao PDR to have a negative opinion of sun bears on their farms, increasing adult sun bear mortality from these interactions. Sun bear populations in Lao PDR are projected to decline by 17% over the next 20 years if no management action is taken. This management plan seeks to stabilize the sun bear population in Lao PDR. As habitat availability is declining, increasing the population is not feasible. The objectives to attain a stable population are to increase the survivorship of sun bears during their mother-dependency period and of the adult stage class. This includes increasing cub survivorship by 5%, yearlings by 4%, and juveniles by 1.5% in 20 years and adults by 1% in 10 years. To increase survivorship of mother-dependent sun bears, planning in forestry operations will be implemented to decrease disturbance levels of these operations and increase their efficiency. Reforestation through plantations will also be initiated in previously deforested areas. Finally, all bear bile extraction farms will be located and shut down to prevent poaching. This plan also looks to improve the opinions of farmers towards sun bears. Objectives to achieve this goal includes reducing the number of farmers who view sun bears as a hindrance to agricultural production by 10% over 15 years and decreasing the number of farmers experiencing property damage by 50% over 20 years. Actions to decrease the proportion of farmers who view sun bears as a hindrance include the establishment of a crop insurance program with the Lao PDR Ministry of Forestry to offset losses of farmers due to damage from wildlife and other natural events. Surveys will also be distributed to gather up to date information regarding the current state of the relationship between farmers and sun bears, and what farmers feel should be done to help them. To decrease property and livestock damage, trained livestock guard dogs (LGD) will be distributed to farmers as a deterrent to keep sun bear off their property. Another preventative measure is to establish electric fences around crops to exclude sun bears from these areas as well as provide a deterring effect from the electric shock. These management actions will likely cause an initial increase in the population above a stable level; however, after 5 years the population will reach a level that can be maintained beyond the 20-year management timeline for up to 100 years.

Distribution and Abundance of Larval Yellow Perch (Perca flavescens) in Lake St. Clair and the Lower St. Clair River, 2018

Mon, 12/02/2019 - 21:23
Abstract: Spatial and temporal dynamics of fish larvae play an important role in determining year-class strength due to variation in habitat quality and food resources that influence larval growth, development, and survival rates. Surveys conducted during the past decade in the St. Clair-Detroit River System have revealed a decline of yellow perch. Genetic and microchemistry analyses showed that these fish make a substantial contribution to the yellow perch stock in western Lake Erie. Our study examines the spatial and temporal distributions of larval yellow perch in Lake St. Clair and the lower St. Clair River to identify important spawning and nursery areas and other ecological factors influencing their early life history. We employed a lake-wide daytime sampling program in 2018 using paired bongo nets to sample pelagic larvae throughout 33 sample locations beginning in mid-March before yellow perch had hatched and continued through mid-July when larvae were absent from samples. Based on our spatial analysis results, Mitchell Bay and Anchor Bay appear as the primary regions for yellow perch spawning habitat and/or nursery grounds for larvae. It is difficult to conclude which factors are influencing the distribution of yellow perch the greatest, but submerged aquatic vegetation, water temperature and clarity likely influence yellow perch vital rates, based on our study. The results from this study give us a growing understanding of the ecological interactions underlying larval yellow perch and their habitat usage during their early life history.

Fish Community Structure with the Reestablishment of Beavers in Beaver Ponds in Smitty Creek Watershed

Tue, 05/07/2019 - 18:15
Abstract: This study is part of a long-term monitoring project, which looks into fish assemblages and the impact beaver reestablishment has on them. Beavers were abundant in 2006, but as of 2011 beavers had left the ponds to go somewhere else, and in this study there was clear signs of beaver presence. The study takes place in a series of continuous beaver ponds located within the Smitty Creek Watershed. Minnow traps were baited and set for 24 hours in order to catch a sample of fish from each pond. Results were compared to data from (2006 and 2011). This year’s data showed two new species of fish that haven’t been found in the beaver ponds before, Northern Pearl Dace (Margariscus nachtriebi) and Finescale Dace (Phoxinus neogaeus). Brook Trout individuals in the study were one lower in 2011, but many more Brook Trout were caught in 2006. Creek Chub have always composed the highest number of fishes. Finescale Dace and Redbelly Dace were found in low abundances.

The Pinocchio Lizard (Anolis proboscis): Conserving Mindo's Hidden Anole

Tue, 05/07/2019 - 11:45
Abstract: EXECUTIVE SUMMARY The Pinocchio lizard (Anolis proboscis) is a cryptic, arboreal anole with in the laevies species group characterized by the unique rostral appendage. Rediscovered in 2005 in Mindo, Ecuador, our understanding of species is limited. The International Union for Conservation of Nature (IUCN) currently lists the species as endangered for its limited extant range within the Andean cloud forests near Mindo (Pichincha). Their reliance on canopy cover with branching twigs makes habitat loss the greatest ecological concern. Anthropomorphic influences such as agriculture, urban development, and oil industry continue to increase the rate of deforestation. The goal of this plan is to provide protection and recover the populations of Pinocchio lizards within 15 years. The following objectives are designed to achieve this goal. (1) Determine population size estimates and detailed suitable habitat requirements of the Pinocchio lizard within 2-3 years. (2) Implement an education and awareness campaign in Mindo within 1 year. (3) Establish the Mindo as a National Park within the next 5 years. (4) Increase survivorship of all life stages within 3 years. Research is needed to develop a detailed understanding is needed to make informed decisions to achieve objectives. Establishing the extant range of the species as a National Park will discourage provide habitat and legal protection. Implementing a captive breeding and reintroduction program will increase immature life stages needed to increase wild populations. If objectives are met successfully, the species will be federally protected throughout its extant range, the population will be stabilized, and will be delisted from the IUCN red list, conserving the biodiversity of Ecuador’s cloud forests.
