title: Pollinator visitation and floral resource production in Black Sand plots for 2019

description: Anthropogenic climate change is altering interactions among numerous species, including plants and pollinators. Plant-pollinator interactions, crucial for the persistence of most plant and many insect species, are threatened by climate change-driven phenological shifts. Phenological mismatches between plants and their pollinators may affect pollination services, and simulations indicated that these mismatches may reduce floral resources available to up to 50 percent of insect pollinator species. Although alpine plants rely heavily on vegetative reproduction, seedling recruitment and seed dispersal are likely to be important drivers of alpine community structure. Similarly, advanced flowering may expose plants to increased risk of frost damage and shifted soil moisture regimes; phenologically advanced plants will experience these environmental factors differently, which may alter their floral resource production. Some species of alpine plants on the Niwot Ridge have displayed advanced phenology under treatments of advanced snowmelt (Forrester, unpublished data). However, little is understood about how these differences in distribution and phenology affect floral resources, pollinator community composition, and plant fecundity. Here we strive to examine how changes in the timing of flowering and number of flowers produced by plants, driven by experimental changes to climatic conditions at individual sites impact pollinator communities. In summer 2019, we found that plots with advanced phenology experienced peaks in pollinator visitation rates and pollinator diversity earlier than plots with unmanipulated snowmelt. We expect this to be because of the advanced floral phenology of certain key species in these plots. We did not find evidence that plants with advanced phenology produce fewer floral resources.

title: Jornada Basin LTER Cross-scale Interactions Study (CSIS) Block 1 meteorological station: 5-minute summary wind and air temperature data: 2013 - ongoing

description: This data package contains 5-minute air temperature and wind summary data from Jornada Basin LTER Cross Scale Interactions Study (CSIS) Block-1 met station. Average air temperature, wind speed, and wind direction are measured and calculated at an automated meteorological station connected to a 900 MHz spread spectrum wireless network. Wind speed is measured at 37cm, 75 cm, 150 cm, and 300 cm, wind direction at approximately 3m, and air temperature and relative humidity at approximate 2.5m. This is a subset of baseline weather data collected at the 15 Jornada Basin LTER CSIS study blocks, New Mexico. Measurements are aggregated at intervals of 5, 30, 60 minutes and daily, with precipitation additionally provided with 1 second aggregation during precipitation events. The met station variables measured include air temperature, precipitation, relative humidity, wind direction, wind speed. Precipitation is not measured at Block 1 and Block 12 because of proximity to Block 2 and Block 13, respectively . This is an ONGOING dataset.

title: Tree Growth and Coarse Woody Debris in Regenerating Forests at Harvard Forest since 2008

description: This project is a field-based study to measure sequestration of atmospheric carbon dioxide in a regenerating New England forest. This study established long-term biometric plots suitable for measuring changes in carbon storage through time in three forest stands: an early-20th-century conifer plantation, a naturally regenerating former conifer plantation harvested in the 1990s, and a conifer plantation scheduled for harvest next winter. The first three years of this project determined the initial carbon budget of these forest stands, measured carbon fluxes into and out of these stands, and laid the groundwork for future investigations. Subsequent years will investigate larger-scale questions, such as how successional patterns affect carbon sequestration, and how these patterns change with stand age. The work also addresses how forestry practices influence carbon sequestration, and provide guidance for how forest management could enhance terrestrial carbon uptake in the future.

title: Assessment of the benthic impacts of raised groundgear for the Eastern Bering Sea pollock fishery, 2014

description: This project addresses the seabed contact and benthic habitat impact aspects of several trawl groundgear configurations. Recent Alaska Fisheries Science Center (AFSC) and industry cooperative work showed that raising trawl groundgear (sweeps and footrope) above the seabed via widely-spaced bobbins reduces the direct contact area of the gear, along with crab mortality and flatfish bycatch; while maintaining fishing performance for pollock. The project fieldwork will compare bottom-contact characteristics and benthic impacts of raised groundgear by systematically varying weight, spacing and seafloor clearance. We aimed to: 1) determine susceptibility of structure-forming geological and biological seabed features to these new groundgear to evaluate the potential for adverse habitat impacts; 2) quantify the component-specific (e.g. sweep, footrope) seabed contact for each groundgear configuration; and 3) compare the contact-adjusted swept areas of, and habitat-feature susceptibilities to, each configuration. The dataset includes multiple types of data: text files, excel files, photos, tilt sensor, DIDSON sonar and video. More specifically, it holds scientists' notes (text files) from the bridge and deck, CSV files containing various information (Metadata workbook, Swept area Workbook and Seafloor Clearance workbook), Globe data (GPS software, Marks and Tracks), and tilt sensor data (Hobo software). There is also underwater video, DIDSON sonar data, photos and video from on deck operations. All seafloor imagery was taken with AFSC built underwater cameras. Also included are still pictures of work operations on the deck of the vessel. The video files and photos have been stored separately and are available upon request. The DIDSON and video data were used to locate the trawl tracks and to do the sea whip condition assessments. The Globe data were used to mark our experimental footrope trawl tracks and our camera/sonar observational sled tows. The Tilt sensor data were used to examine the height off bottom of various footrope components. The CSV files consolidate the raw data in the Metadata workbook; the Swept Area file contains the cleaned data used in Swept Area models, and the Seafloor Clearance file contains the Tilt sensor data and how the sensors were calibrated. This dataset was generated under NPRB project 1319.

title: Fishery, Climate, and Ecological Effects on Pacific Halibut Size-at-age in the Gulf of Alaska

description: This study investigated the size-at-age (SAA) of Pacific halibut in the Gulf of Alaska and Bering Sea. In the past two decades, the size-at-age of halibut has undergone an extensive reduction. Observed SAA of Pacific halibut has changed substantially over time and the reasons behind changes in halibut SAA are not well understood. This project compared new and historical surface ages to demonstrate whether a differing degree of bias is present in surface ages made in earlier decades relative to those made today due to factors such as changes in surface age assignment protocol over time or quality of microscopes used. Data are presented as fifteen CSV files: Decadal re-aging: NPRB_1309_1_decadal_reaging_data.csv Otolith and maturity codes: NPRB_1309_1_decadal_reaging_codes.csv NPRB_1309_1_individual_increment_codes.csv Increment data includes one CSV file for each cohort (1977, 1987, 1992, 2002) and IPHC Regulatory Area (2B, 3A and 4D): NPRB_1309_1_individual_increment_data_2B_1977.csv NPRB_1309_1_individual_increment_data_3A_1977.csv NPRB_1309_1_individual_increment_data_4D_1977.csv NPRB_1309_1_individual_increment_data_4D_1987.csv NPRB_1309_1_individual_increment_data_3A_1987.csv NPRB_1309_1_individual_increment_data_2B_1987.csv NPRB_1309_1_individual_increment_data_3A_1992.csv NPRB_1309_1_individual_increment_data_2B_1992.csv NPRB_1309_1_individual_increment_data_4D_1992.csv NPRB_1309_1_individual_increment_data_2B_2002.csv NPRB_1309_1_individual_increment_data_3A_2002.csv NPRB_1309_1_individual_increment_data_4D_2002.csv
