Energy cover crops for biogas production increase soil organic carbon stocks: A modeling approach
The anaerobic digestion of cover crops for biogas production does not compete directly with food production and is promoted in various countries. Some questions arose regarding the effects of energy cover crops on soil organic carbon (SOC) stocks.

Survey for Etomopathogenic Nematodes and Entomopathogenic Fungi in Alfalfa Snout Beetle, \u3ci\u3eOtiorhynchus Ligustici\u3c/i\u3e (L.) (Coleoptera: Curculionidae), Infested Fields in Hungary and in New York State [PDF]
A survey for etomopathogenic nematodes and fungi in alfalfa snout beetle Otiorhynchus ligustici (L.) infested fields was conducted in Hungary, where this beetle is native, and in New York State, where the alfalfa snout beetle is an invasive species. Soil

The Arecibo Pisces-Perseus Supercluster Survey I: Harvesting ALFALFA [PDF]
We report a multi-objective campaign of targeted 21 cm HI line observations of sources selected from the Arecibo Legacy Fast ALFA (Arecibo L-band Feed Array) survey (ALFALFA) and galaxies identified by their morphological and photometric properties in the Sloan Digital Sky Survey (SDSS).

Temporal methane dynamics in the surface waters of a stratified eutrophic lake over four years
Abstract The occurrence of oxic methane production (OMP) has been reported for numerous aquatic ecosystems. Its seasonal dynamics and contribution to global methane (CH4$$ {\mathrm{CH}}_4 $$) emissions remains uncertain, however, due to the lack of measurements constraining the spatial and temporal variability of OMP.

ALFALFA: The Search for (Almost) Dark Galaxies and their Space Distribution [PDF]
The Arecibo Legacy Fast ALFA (ALFALFA) survey is designed to explore the z=0 HI mass function (HIMF) over a cosmologically significant volume. ALFALFA will improve on previous determinations of the HIMF by its combination of depth, wide area and centroiding accuracy, the latter allowing, in most cases, immediate identification of the optical ...

Humans and honey bees have a long history of interaction to yield valued products and services. However, honey bees are under pressure from changes in vegetation, agricultural practices and climate change. We investigate if pasture legumes can be harnessed to support honey bees. We use a diverse set of species that originated from the Mediterranean and

Click beetle (Elateridae) olfactory preferences for plant volatiles, including those released by damaged plants, remain poorly understood. Olfactometer and electroantennography experiments revealed sex‐ and plant species‐specific olfactory preferences of Agriotes sputator beetles, with maturity influencing female responses.
