Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

Impact of Bee Species and Plant Density on Alfalfa Pollination and Potential for Gene Flow

Psyche: A Journal of Entomology, 2010
In outcrossing crops like alfalfa, various bee species can contribute to pollination and gene flow in seed production fields. With the increasing use of transgenic crops, it becomes important to determine the role of these distinct pollinators on alfalfa

The conservation of bumble bees [PDF]

Bee World, 2003
The approximately 250 known species of bumble bee (genus Bombus) are found predominantly in temperate regions of the northern hemisphere. This region also contains much of the world's human population and the most intensive agricultural regions. Probably as a result of this, many bumble bees appear to be undergoing dramatic declines in range.

Do Laboratory‐Reared Flies Perform Differently as Pollinators? Morphology, Behaviour and Pollination Performance of Eristalis tenax (Syrphidae)

Journal of Applied Entomology, Volume 150, Issue 6, Page 716-727, July 2026.
ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Extrafloral nectaries on Cenchrus americanus (L.) Morrone

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Pearl millet, Cenchrus americanus (L.) Morrone (formerly Pennisetum glaucum L.), used for food and feed, has pollen that attracts multiple insect species. In 2023, honey bees and wasps were observed foraging on or below the auricles of pearl millet in a Georgia field.

The Wonders of Vanilla: Celebrating the 150th Anniversary of Synthetic Vanillin

ChemFoodChem, Volume 2, Issue 2, June 2026.
The year 2024 marked the 150th anniversary of the first commercial production of vanillin, one of the world's most cherished flavor ingredients. This review traces vanilla's history from Mesoamerica to modern production methods, examines its composition, the discovery of vanillin and Haarmann's early synthesis compared to modern methods, and highlights
