In 1993, we installed 40 circular, 10 m radius biometric plots in the footprint of the EMS tower on Prospect Hill. We randomly placed the plots within 100 m increments along ten 500 m transects that extend from the tower in the northwest and southwest directions. In 2001, we removed three plots (G3,

The purpose of this study was to track year-to-year variation in aphid abundance on the host plant Ligusticum porteri (Apiaceae). We censused arthropod abundance on the flowering stalks of L. porteri weekly in June-August from 2017 to 2020. The censuses took place in ten L. porteri populations near

This release includes Python codes and associated field sampling and remote sensing data for the estimation of the spatial distribution of soil thickness in two hillslopes in the Pump House area in the East River Watershed in the CO., the U.S.

Bumble bee queens initiate nests solitarily and transition to living socially once they successfully rear their first cohort of offspring. Bumble bees are disproportionately important for early season pollination, and many populations are experiencing dramatic declines. In this system, the onset of

Navigation, surface current, sea surface temperature, wind, and atmospheric pressure data collected by the Mar Mostro during the around-the-world Volvo Ocean Race (VOR) 2011-2012 (http://www.volvooceanrace.com/en/home.html). The Mar Mostro is a 21.5m sail-powered racing yacht that was manned by the

From 1872 to 1876, the HMS Challenger sailed around the world studying ocean features such as ocean temperature and chemistry, wildlife, and sounding the ocean, discovering undersea features like seamounts and ocean trenches. This expedition marked the beginning of the modern study of oceanography.

This dataset includes surface underway data collected during the racing sailing vessel Seaexplorer (Malizia II) cruises in the Atlantic Ocean, Indian Ocean and Pacific Ocean from 2020-07-03 to 2021-01-05. These data include partial pressure of carbon dioxide in the water, sea surface salinity, sea s

The Phytoplankton Monitoring Network (PMN) is a part of the National Centers for Coastal Ocean Science (NCCOS). The PMN was created as an outreach program to connect volunteers and professional scientists in the monitoring of marine phytoplankton and harmful algal blooms (HABs). NOAA staff train vol

Species responses to climate change depend on environment, genetics, and interactions among these factors. Intraspecific cytotype (ploidy level) variation is a common type of genetic variation in many species. However, the importance of intraspecific cytotype variation in determining demography acro

Maintaining the diversity of wild bees is a priority for preserving ecosystem function and promoting stability and productivity of agroecosystems. However, wild bee communities face many threats and beekeeping could be one of them, because honey bees may have a strong potential to outcompete wild po

Organismal traits often influence fitness via interactions with multiple species. That selection is not necessarily predictable from pairwise interactions, such as when interactions occur during different lifecycle stages. Theoretically, directional selection during two sequential episodes, e.g., po
