Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use

Agricultural and Forest Entomology, EarlyView.
Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

Alive and dead earthworms capture carbon during mineral weathering through different pathways

Communications Earth & Environment
Enhanced rock weathering aims at capturing atmospheric carbon dioxide as inorganic carbon, while potentially stabilizing soil organic carbon. However, the role of soil biota in this process remains underexplored. Earthworms, being key soil engineers, may

Comparing Methods for Measuring Predation: Toward a Quantitative–Informative Indicator of Natural Pest Control

Entomologia Experimentalis et Applicata, EarlyView.
Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.

Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

Entomologia Experimentalis et Applicata, EarlyView.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.

Impact of different farming systems on epigeic beneficial arthropods and earthworm fauna in arable crops [PDF]

, 2004
In dieser Arbeit wurden die Auswirkungen unterschiedlicher traditioneller (konventionell, integriert) und biologischer (organisch-biologisch, bio-dynamisch) Anbausysteme auf die epigäischen Nutzarthropoden und die Regenwurmfauna untersucht.

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

Ibis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

Microflora dynamics in earthworms casts in an artificial soil (biosynthesol) containing lactic acid oligomers

Brazilian Archives of Biology and Technology, 2001
Studies were performed to appreciate the presence of micro-organisms able to degrade OLA, in earthworms casts or in the surroundings. Worms were grown in biosynthesol, an artificial soil.

Expansion of invasive carabids across elevation and habitats on sub‐Antarctic South Georgia

Insect Conservation and Diversity, EarlyView.
Two introduced carabid species have continued to expand their ranges on the sub‐Antarctic island of South Georgia over the past 10–15 years. The species have colonised inland valleys and are present across habitats but are more abundant in those with high vegetation cover. N‐mixture models revealed the optimal sampling method, intensity and habitat for

Alternative Protein Sources in Poultry and Pig Nutrition—A Review

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Proteins are an essential nutrient for the viability of all animals, enabling organisms to grow, regenerate and defend themselves against pathogenic organisms. Soybean and soybean‐based materials are commonly used to supplement protein in animal nutrition.
