The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Latitudinal distribution and mitochondrial DNA (COI) variability of Stereotydeus spp. (Acari: Prostigmata) in Victoria Land and the central Transantarctic Mountains [PDF]

, 2010
We examined mitochondrial DNA (COI) variability and distribution of Stereotydeus spp. in Victoria Land and the Transantarctic Mountains, and constructed Neighbour Joining (NJ) and Maximum Likelihood (ML) phylogenetic trees using all publicly available ...

Springtails—Worldwide Jumpers [PDF]

Frontiers for Young Minds, 2020
Springtails are tiny, six-legged animals that you meet every day, but hardly notice. They can survive in big cities, on ice in Antarctica, in the deepest caves, and in rainforest canopies. Some scientists call them the earliest known and the most numerous insects on Earth.

Evaluating the efficacy of tagging adhesives for insect tracking

Agricultural and Forest Entomology, EarlyView.
Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.

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.

Effects of compost and digestate on environment and plant production – results of two research projects [PDF]

, 2008
A yearly amount of 9.3x106t compost and digestate derived from separately collected organic waste is produced in the 25 European Union member states. The improvement of soil properties is a major benefit of compost application.

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

Soil biodiversity: functions, threats and tools for policy makers [PDF]

, 2010
Human societies rely on the vast diversity of benefits provided by nature, such as food, fibres, construction materials, clean water, clean air and climate regulation.

Swine Manure‐Derived Black Soldier Fly (Hermetia illucens L.) Frass Enhances Chilli (Capsicum annuum L.) Vegetative Growth and Soil Epigeic Macro‐Arthropod Abundance

Journal of Applied Entomology, EarlyView.
ABSTRACT The rapid expansion of swine production has increased environmental concerns related to nutrient pollution and improper manure management. Black soldier fly (BSF) larvae offer a promising bioconversion approach, producing frass that may serve as a sustainable organic fertiliser.
