Watershed Level Occurrences of Yellow Lampmussel from Museum and Survey Data Watershed Level Occurrences of Yellow Lampmussel from Museum and Survey Data

Natural history museum records may provide unique information on the distribution of species additional to survey data collected by resource managers. However, there can be challenges to using museum data for analyses such as spurious geographic information, misidentifications, and incorrect labeling. Museum records have been centralized by open-source repositories with flags for...

Water quality of the Jim Bertram Lake System, Lubbock, Texas: Oct 2021-Oct 2023 Water quality of the Jim Bertram Lake System, Lubbock, Texas: Oct 2021-Oct 2023

Data are found in two separate *.csv files. File 1 contains the data and file 2, the sampling site coordinates. The data describes the results of water quality measurements in the Jim Bertram Lake System, an impounded urban stream system in Lubbock, Texas. Measurements were taken from October 2021 through October 2023.

Chronic wasting disease (CWD) survey by hunters in Massachusetts in early 2023. Chronic wasting disease (CWD) survey by hunters in Massachusetts in early 2023.

We implemented an online survey questionnaire for adult Massachusetts licensed hunters in December 2022-February 2023 using the Qualtrics survey platform (Qualtrics, Provo, UT). The online survey covers a number of topics related to chronic wasting disease (CWD) such as knowledge, risk perception, management acceptability, hunting behavior, channel use, and trust in different sources. Of...

Suspended Sediment Conditions to Hyporheic Dissolved Oxygen and Fine Sediment Deposition in Salmonid Spawning Habitat Below an Irrigation Dam, Park County, Wyoming Suspended Sediment Conditions to Hyporheic Dissolved Oxygen and Fine Sediment Deposition in Salmonid Spawning Habitat Below an Irrigation Dam, Park County, Wyoming

We quantified the effects of dam sediment management operations on downstream salmonid spawning habitat during two fall water-level drawdown periods: an experimental drawdown leading to sediment release or a typical slower drawdown intended to minimize release of sediment. The experimental drawdown increased deposited fine sediment and decreased hyporheic dissolved oxygen levels. However...

Data describing a predatory fish invasion on a riverine food web Data describing a predatory fish invasion on a riverine food web

Catfishes are opportunistic feeders that are among the world's worst invasive species. Flathead catfish *Pylodictus olivaris* -- a large predatory catfish -- were first detected in the Susquehanna River, Pennsylvania, USA in 2002. Since then, they established a viable and rapidly growing population that is expanding its range throughout the river system. Although the predatory effects of...

Data for Distance sampling accounting for density gradient and animal distribution Data for Distance sampling accounting for density gradient and animal distribution

There are 9 datasets. one distance sampling dataset, 4 resource selection datasets, and 4 outputs from bootstrapped resource selection models the use the estimated correction factor. The 4 resource selection datasets have data that can be used in a binomial generalized linear mixed effect model to create the correction factor. The distance sampling data set is used to estimate density...

Predicting wildlife distribution patterns in New England USA with expert elicitation techniques Predicting wildlife distribution patterns in New England USA with expert elicitation techniques

Understanding the impacts of landscape change on species distributions can help inform decision-making and conservation planning. Unfortunately, empirical data that span large spatial extents across multiple taxa are limited. In this study, we used expert elicitation techniques to develop species distribution models (SDMs) for harvested wildlife species (n = 10) in the New England region...

Code for long-term monitoring reveals management effects on Prairie Warbler colonization, local extinction, and detection in a Massachusetts Pine Barren Code for long-term monitoring reveals management effects on Prairie Warbler colonization, local extinction, and detection in a Massachusetts Pine Barren

This repository contains all of the scripts to reproduce the analyses, figures, and tables associated with the manuscript Gordon et al. in prep. There is 1 R script that does the following: (1) format the data, (2) explores the data, and (3) goes through the analyses for each objective.

Occupancy surveys near Marbled Murrelet (Brachyramphus marmoratus) nest sites and random locations between 2018 and 2022 along the central Oregon coast, USA Occupancy surveys near Marbled Murrelet (Brachyramphus marmoratus) nest sites and random locations between 2018 and 2022 along the central Oregon coast, USA

There are four data tables (csv documents) provided here which are formatted according to tidy data principles. We identified sites centered on known murrelet nest trees (nest sites) and on randomly selected trees (control sites) and the first table contains variables that vary at the site level. Each site had up to three stations where occupancy surveys were collected, so the second...

Missouri Stream Conservation and Connectivity Prioritization Tool: Improving and Expanding Existing Conservation Networks Missouri Stream Conservation and Connectivity Prioritization Tool: Improving and Expanding Existing Conservation Networks

The Missouri Stream Conservation and Connectivity Prioritization Tool contains data tabulating costs to traverse between 10,357 origin and 50,135 destination stream reaches throughout the Central Plains and Ozarks aquatic subregions in Missouri. Below are links to data associated with the more northern drainages and also the southern drainages. These data are intended to be used in the...

Wood Thrush Movement and Occupancy Wood Thrush Movement and Occupancy

This code contains multiple scripts that (1) analyze Wood Thrush movement data, (2) simulate Wood Thrush movements in an individual-based model, and (3) analyze the results from these simulations.

Corresponding dataset for effectiveness of canine-assisted surveillance and human searches for early detection of invasive spotted lanternfly Corresponding dataset for effectiveness of canine-assisted surveillance and human searches for early detection of invasive spotted lanternfly

This study experimentally tested whether utilizing trained detector dogs could improve the probability of detecting SLF in both agricultural and forest settings. This dataset includes the data from spotted lanternflys (SLF) surveys in 20 vineyards in Pennsylvania and New Jersey, USA using both human and trained detection dogs as observers. We used a multi-scale occupancy model to...
