Integrated Farm System Model (IFSM)

The Integrated Farm System Model (IFSM) is a process-based simulation of dairy, beef, and crop farming systems. This whole farm model provides a tool for evaluating the long term performance, economics, and environmental impacts of production systems over many years of weather.

Systema Dipterorum

Two-winged insects or Diptera comprise 12% of the planetary biota, and the Systema Dipterorum is an authoritative source for their names. Systema Dipterorum contains all names proposed for extant and extinct Diptera and it is a source for information about those names. The two main components of Systema Dipterorum are the Nomenclator and the References database. By providing authoritative information about dipteran names, Systema Dipterorum is the necessary framework for organizing, interpreting and integrating current and future data, information and knowledge about two-winged insects.

Treehopper Immatures Project

The attached, linked files provide the characters and character matrix for publications describing immatures of the New World treehoppers (Membracidae, Melizoderdae, and Aetalionidae) by McKamey, Wallner, Porter, Wallace, and Phillips, or some combination thereof. Characters for each body part are assigned a number, and each character within each body part are assigned a letter, because additional characters (and states) are expected to be discovered with each newly examined tribe or subfamily and it is desirable to keep all characters pertaining to a body part together. With each publication, both of these linked files will be updated. Presently, the characters and matrix cover the tribes Amastrini and Thuridini (Smiliinae).

Honey

This file contains the annual report of the number of colonies producing honey, yield per colony, honey production, average price, price by color class and value; honey stocks by state and U.S. from Sep 24, 1976 to Mar 22, 2017. Beginning with this publication, new tables have been added with estimates on expenditures, incomes, and other data related to beekeeping.

Data from: Transcriptomes of bovine ovarian follicular and luteal cells

Gene 1.0 ST Array RNA expression analysis was performed on four somatic ovarian cell types: the granulosa cells (GCs) and theca cells (TCs) of the dominant follicle and the large luteal cells (LLCs) and small luteal cells (SLCs) of the corpus luteum. The normalized linear microarray data was deposited to the NCBI GEO repository (GSE83524). Subsequent ANOVA determined genes that were enriched (≥2 fold more) or decreased (≤−2 fold less) in one cell type compared to all three other cell types, and these analyzed and filtered datasets are presented as tables. Genes that were shared in enriched expression in both follicular cell types (GCs and TCs) or in both luteal cells types (LLCs and SLCs) are also reported.

Animal Germplasm Resources Information Network

Animal genetic resources underpin the livestock sector's production and profitability. As a result livestock industries contribute billions of dollars to national economies. The Animal Germplasm Resources Information Network mission is to acquire, evaluate and preserve these strategic resources so that industry and the research community can have access to a broad array of genetic variability for: national security, introduction of genetic variation, corrective breeding, and various research initiatives.
