Data on interannual seed set variation, weather, and reproductive traits for global plants

Data were collected on seed production dynamics of long-lived plants, reproductive plant traits of those plant species, and weather variability for sites where those species live. Data include the coefficient of variation in seed production over time, the variation (coefficient of variation or standard deviation) in weather over years, and reproductive traits such as pollination mode

Detection and non-detection records of Saipan's terrestrial herpetofauna, 2018

There are two datasets included in this entry. The diurnal dataset contains 28 columns of data collected during transects surveys. The nocturnal dataset contains 52 columns. We randomly select 56 sites, each 50 m in length, from 37,968 m of transects spanning the island that were originally created for bird surveys in 1982 through the cooperative efforts of the U.S. Fish and Wildlife Servic...

Data on cone production in pinyon pine in the Southwestern USA from 2003-2016

Data were collected on pinyon pine cone production using the cone scar method (Redmond et al 2016 Forest Ecology and Management) from 2003-2016 among sites in the Southwest USA. Long-term weather data (Vapor Pressure Deficits and monsoonality) were associated with cone scar data to assess weather-correlates of cone production.

Data Release: Possibility for reverse zoonotic transmission of SARS-CoV-2 to free-ranging wildlife: a case study of bats

This is the supplementary table that accompanies the manuscript by Olival et al. entitled 'Possibility for reverse zoonotic transmission of SARS-CoV-2 to free-ranging wildlife: a case study of bats'. The table illustrates global patterns of betacoronavirus (β-CoV) associations in bats. The table lists bat species in which betacoronaviruses (β-CoVs) were detected, organi

Sample collection information and SNP data for Gunnison Sage-grouse across the species range generated in the Molecular Ecology Lab during 2015-2018

This dataset contains sample collection information and SNP genotypes for populations of Gunnison Sage-grouse across the species' range. This data was collected in order to examine patterns of adaptive genetic variation in Gunnison Sage-grouse. The data is archived in GenBank at the following URL https://www.ncbi.nlm.nih.gov/bioproject/...

Data on gall wasp abundance and biomass on valley oak and blue oak trees in California

Gall abundance and biomass was recorded on marked valley oak and blue oak individuals throughout California. Galls, mostly caused by cynipid gall wasps, were identified to species. Sampling effort per tree was recorded as the number of leaves searched for gall wasps. Leaves were taken from two branches per tree using pole pruners, and total galls per tree were summed in each observation...

Location and phenology observations for beaked hazelnut (Corylus cornuta), Oregon grape (Mahonia aquifolium), and salal (Gaultheria shallon) in western North America

These data provide the locations and phenological dates of three shrub species: beaked hazelnut (Corylus cornuta), Oregon grape (Mahonia aquifolium), and salal (Gaultheria shallon), collected from various publicly available data sources including data from USFS Forest Inventory and Analysis program, USFS R-6 Ecology Program, US National Park Service, USDI Bureau of Land

Demographic data from two chorus frog populations in Colorado

We used 29 years of data on boreal chorus frogs at two sites to view life-history, estimate demographic parameters, assess weather-related covariates, and determine the magnitude of process variation in target parameters. Average estimates of survival probabilities were 0.51 (Standard error [SE]=0.04) and 0.43 (SE=0.04), and average estimates of recruitment probabilities w

Riparian vegetation, topography, and sediment quality along the Lower Virgin River 2010-2017

The data release presents observations of riparian vegetation, topography, and sediment quality in five river reaches of the Lower Virgin River extending downstream 62 river kilometers (rkm), from near the town of Littlefield (AZ) to approximately 15 rkm upstream from the confluence with the Muddy River (NV). Methods included field observations and analysis of the plant communit

Photogrammetric data collected by small unoccupied aircraft system for vegetation analysis at Childs along the Verde River, Arizona, December 2017

The U.S. Geological Survey collected low-altitude airborne visual imagery via a multirotor, small unoccupied aircraft system (sUAS) along with Real Time Kinematic (RTK) GPS survey data at Childs along the Verde River in Arizona in December 2017. Visual imagery was collected in jpg format and Structure from Motion techniques were applied to the visual imagery to derive a time-specific hi
