Freshwater fish and mussel projections in the Northeastern United States at the HUC12 scale under different climate and land use scenarios Freshwater fish and mussel projections in the Northeastern United States at the HUC12 scale under different climate and land use scenarios
These data comprise the results of an analysis to 1. develop freshwater fish and mussel models using survey occurrence data, land use data, stream flow data, and stream temperature data within the Northeast United states, 2. predict the impacts of climate change on vulnerable groups of freshwater fish and mussel species, and 3. assess the potential for different management interventions...
Fish species occurrence data (HUC12) in Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island Fish species occurrence data (HUC12) in Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island
This data release includes the results of state agency led electrofishing surveys conducted in lotic habitats in six states in the Northeastern U.S.: Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island. The following state agencies collected the electrofishing data: Massachusetts Division of Fisheries & Wildlife, Vermont Department of Fish and Wildlife, Vermont...
Daily ice cover fractions for 107,257 lakes in the Northern Hemisphere Daily ice cover fractions for 107,257 lakes in the Northern Hemisphere
This dataset provides estimated daily ice cover fractions for 107,257 lakes across the Northern Hemisphere from 1980 to 2022. The ice cover fractions were generated using a deep learning model trained on Landsat observations. The model's code is publicly available in the USGS GitLab repository: https://doi.org/10.5066/P13ZGUGE. The dataset consists of 42 CSV files, each corresponding to...
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...
Winter tick counts and covariates in Massachusetts and New Hampshire from fall 2022 Winter tick counts and covariates in Massachusetts and New Hampshire from fall 2022
The dataset accompanies manuscript: "Monitoring off-host winter tick abundance on traditional moose hunting lands" . It is a single table that includes counts of winter tick (Dermacentor albipictus) obtained by a modified flagging technique developed by the Penobscot Nation. The table includes both detection and site covariates used for the data analyses presented in the paper. Data were...
Data used to test a video monitoring and computational system for estimating juvenile fish abundance Data used to test a video monitoring and computational system for estimating juvenile fish abundance
We developed and tested neural network-based models to recognize and count emigrating juvenile river herring in continuous video. Continuous video was collected from an underwater camera installed at Great Herring Pond in Bourne, Massachusetts (USA) between June and November 2017. Our algorithm extracts video frames to assess presence/absence of fish and count numbers of fish emigrating...
Developing a Stochastic Hydrological Model for Informing Lake Water Level Drawdown Management Developing a Stochastic Hydrological Model for Informing Lake Water Level Drawdown Management
This data release consists of four datasets which were used for evaluating winter drawdown (WD) lakes to follow the Massachusetts general WD guidelines. The first dataset ("Water level observations.csv") provides water level monitoring data of 21 (18 WD and 3 non-WD) recreational lakes in Massachusetts from 2014 to 2018. The water levels were measured by paired nonvented pressure...
In-vitro Propagation and Fish Assessments to Inform Restoration of Dwarf Wedgemussel (Alasmidonta Heterodon) In-vitro Propagation and Fish Assessments to Inform Restoration of Dwarf Wedgemussel (Alasmidonta Heterodon)
The dwarf wedgemussel (Alasmidonta heterodon) is a federally endangered freshwater mussel that once ranged from New Brunswick to North Carolina, but now only exists in isolated populations throughout its diminished range. Laboratory propagation in conjunction with augmentation or reintroduction is considered a critical component of dwarf wedgemussel restoration. The presented data aimed...
