Cave and Karst Biota Modeling in the Appalachian LCC - Predicted endemics in sampled 20km grid cells

We developed spatial summary (GIS) layers for a study of factors influencing the distribution of cave and karst associated fauna within the Appalachian Landscape Conservation Cooperative region, one of 22 public-private partnerships established by the United States Fish and Wildlife Service to aid in developing landscape scale solutions to conservation problems (https://lccnetwork.org/lcc/appalachian). We gathered occurrence data on cave-limited terrestrial and aquatic troglobiotic species from a variety of sources within the Appalachian LCC region covering portions of 15 states. Occurrence records were developed from the scientific literature, existing biodiversity databases, personal records of the authors, museum...

Development of a Regional Springsnail Conservation Strategy

FY2017There is an increasing concern and need for the conservation of springsnails and other endemic mollusks and for conservation of the unique spring and springbrook habitats on which they depend (Hershler et al 2014; Abele 2011). Nationwide, several of these species have been listed as endangered or threatened under provisions of the ESA; others are candidates for federal listing or are undergoing review by USFWS for possible future listing actions. These species can be particularly susceptible to localized threats and specific knowledge necessary for effective site-based conservation is often limited or lacking.Springsnail are particularly susceptible to extinction because the entire population of any single...

Microsatellite genotypes for Lake Sturgeon (Acipenser fulvescens) Eggs and Larvae from Constructed Reefs in the St. Clair-Detroit River System (2015-2016)

This dataset contains the physical collection information (e.g., sample location, date, gear type) and microsatellite DNA genotype of egg and larval Lake Sturgeon collected in the St. Clair and Detroit rivers in 2015 and 2016. Individuals were genotyped for 18 microsatellite loci (13 disomic and 5 polysomic). Alleles (base pair sizes) were recorded as presence absence scores (1:present, 2:absent, 0:missing data) for all previously observed alleles. Thus individual genotypes were recorded as pseudo diploid dominant phenotypes resulting in individual vectors of length n=205 for each genotyped egg or larval individual.

Northwestern Hawaiian Islands Laysan duck survival 1998–2018

Monitoring demographic response over time is valuable for understanding population dynamics of endangered species. We quantified the variation in survival patterns for three small isolated island populations of endangered Laysan ducks (Anas laysanensis; also called Laysan teal) in the Hawaiian Archipelago using data from individually marked birds. Using the median or maximum resight intervals of individually marked birds and carcass recovery dates the survival of ducks at Laysan Island, Midway Atoll, and Kure Atoll was estimated. This dataset includes demographic information for each bird released, mortality information, and data used to calculate population survival.

Confronting uncertainty in species distribution projections

The CA Academy of Science and Point Blue Conservation Science conducted a systematic analysis of uncertainty in modeling the future distributions of ~50 California endemic plant species and ~50 California land birds, explicitly partitioning among 5 alternative sources of variation and testing for their respective contributions to overall variation among modeled outcomes. They mapped the uncertainty from identified sources, which can guide decisions about monitoring, restoration, acquisition, infrastructure, etc., in relation to climate change.

The relevance of wetland conservation in arid regions: A re-examination of vanishing communities in the American Southwest

Desert wetlands, or ciénegas, are regions of high conservation value in the American Deserts. These environments, in the Apache Highlands Ecoregion spanning the borderlands of Arizona, USA and Sonora, México, contain an estimated 19% of endangered, threatened and candidate species within 2% of the regional area. Besides being crucial refugia for native fish, amphibians, snails, and plants, ciénegas constitute critical habitat for migratory birds. Here we analyze the distribution, conservation status and restoration potential of ciénegas in this region. Our results identified 97 ciénegas of which only 60 had information useful for our analysis. Of these, 46 ciénegas were considered functional, or extant, while the...

BLM REA COP 2010 TNC Conservation Areas

This geodatabase contains geographic and tabular information pertaining to priority conservation areas in western North America. The region encompasses a sequence of mountain ranges, including the Rocky Mountains, that form the backbone or spine of the western North America, along with the surrounding deserts and semi-arid lands. Priority conservation areas (hereafter referred to as conservation areas) are geographic areas that have been selected because of the sensitive biological species, habitats, and features (hereafter referred to as targets) that are known to occur in these areas. Conservation, protection, and management actions within these areas should be prioritized in order to ensure persistence and survival...

Demographic Measurements to Inform a Brood Translocation Integrated Population Model

Wildlife managers translocate greater sage-grouse (Centrocercus urophasianus; sage-grouse) to augment small populations, but translocated sage-grouse often fail to reproduce post-release, sometimes hampering conservation objectives. We performed two distinct sage-grouse translocation projects in California and North Dakota from 2017-2020 and employed two translocation methods at both sites: an established method of translocating females prior to the nesting season (i.e., a pre-nesting translocation), and a novel method wherein females were translocated with chicks after successfully hatching a nest in the source population (i.e., a brood translocation). Using an integrated population model (IPM), we estimated recruitment...

Indo-West Pacific species of Trachinotus with spots on their sides as adults, with description of a new species endemic to the Marquesas Islands (Teleostei: Carangidae)

The dataset is a composite of morphological data used in the description of a new species of marine fish, Trachinotus macrospilus (Teleostei: Carangidae), endemic to the Marquesas Islands of the Indo-West Pacific. In the addition to the newly described species, three previously named (nominate) species of the same genus are compared and redescribed in this same manuscript. The morphological data include both mensural (morphometric) and meristic (count) data. Synonymies are provided for all species, since many misidentifications have been made in the literature, which dates to the early 1800's.
