Entomology as a Career [PDF]

open access: yesNature, 1949
EVERY generation produces a number of young naturalists, some of whom seek a career in which they can follow their interests. Of these a proportion have in the past turned to entomology, and it is to be hoped that they will continue to do so in the future. The proceedings of a recent conference held in London, the Second International Congress of Plant

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Highly Efficient Use of Infrared Spectroscopy (ATR-FTIR) to Identify Aphid Species

open access: yesBiology, 2022
Aphids are commonly considered to be serious pests for trees, herbaceous and cultivated plants. Recognition and identification of individual species is very difficult and is based mainly on morphological features.

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

open access: yesBiological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Biotic and abiotic drivers of ecosystem functioning differ between a temperate and a tropical region

open access: yesEcography, EarlyView.
Any single ecosystem will provide many ecosystem functions. Yet, we lack large‐scale, systematic studies of how abiotic factors can directly or indirectly – via effects on biodiversity – drive ecosystem functioning. In this study, we assessed the impact of climate, landscape and biotic community on ecosystem functioning in the temperate and tropical ...

Forensic entomology [PDF]

open access: yesClinical Medicine, 2003
Forensic entomology is the application of insect biology to the investigation of crime. The subject covers all aspects of insect evidence, but for the purpose of this article the discussion will be restricted to insect evidence from the bodies of persons thought to have been the victims of murder or other unlawful killing.

Optimising the Eco‐Friendly Extraction of Carotenoids From Gac Fruit: A Sustainable Solution for Natural Red Food Colourants

open access: yesFood Chemistry International, EarlyView.
Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...

Green water, wetlands, and atmospheric moisture recycling ‐ An emerging new paradigm for grassland science

open access: yesGrassland Research, EarlyView.
The importance of green water in water resource management. Conceptual classification of terrestrial water components highlighting the central role of green water in land‐atmosphere interactions. This schematic distinguishes green water (soil moisture available for plant uptake and evapotranspiration) from blue water (surface water, groundwater, and ...

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Ozonation as a promising approach to improve stored rice quality in Ghana

open access: yesJSFA reports, EarlyView.
Abstract Background Two species of rice pests that are responsible for postharvest losses, the rice weevil (Sitophilus oryzae) and the Angoumois moth (Sitotroga cerealella), are major destructive pests responsible for paddy grain deterioration. A benchtop custom‐built model of ozone‐generating equipment from ozone generator DKM‐10GY, producing 2000 ppm
