Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

open access: yesGrassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Pollination in an endemic and threatened monoecious herb Begonia satrapis C.B. Clarke (Begoniaceae) in the eastern Himalaya, India

open access: yesJournal of Threatened Taxa, 2019
Begonia satrapis was studied for its pollination aspects at Sumbuk, Sikkim, India.  The floral details and the foraging behaviour of insects visiting the flowers were examined to define the pollination syndrome and its functionality for the success of ...

Variation and evolution of herkogamy in Exochaenium (Gentianaceae): implications for the evolution of distyly [PDF]

open access: yes, 2017
Backgrounds and Aims The spatial separation of stigmas and anthers (herkogamy) in flowering plants functions to reduce self-pollination and avoid interference between pollen dispersal and receipt.

A guide to sunflowers: floral resource nutrition for bee health and key pollination syndromes

open access: yesFrontiers in Plant Science
Sunflower, Helianthus annuus L., is a prominent global oilseed crop with rising cultivation and appeal as a bee-friendly plant by providing abundant floral resources for pollinators. Mass-flowering crops can increase the availability of resources, and sunflower is a good opportunity to relieve pollen scarcity during the late summer in agricultural ...

Interkingdom Interactions in the Gut: Ecological Mechanisms, Homeostasis, and Therapeutic Modulation

open access: yesGut Medicine, EarlyView.
ABSTRACT The gut microbiota constitutes a highly complex and dynamic ecosystem that profoundly influences host physiology, metabolism, and immunity. This review provides an integrative overview of the mechanisms through which gut microorganisms—particularly bacteria and fungi—interact with host cells and with each other to maintain intestinal ...

Probiotics‐derived postbiotics improve host metabolic syndrome by activating the adipocyte thermogenic signaling pathway in high‐fat diet‐fed mice

open access: yesiMetaOmics, EarlyView.
This schematic illustrates how probiotics‐derived postbiotics (PLBK®1–5) combat high‐fat diet‐induced obesity. Postbiotics remodel gut microbiota, boosting beneficial metabolites. These metabolites activate adipocyte thermogenesis (Ucp1/AMPK pathway), resulting in reduced body weight, improved insulin sensitivity, and alleviated hepatic steatosis in ...

Visual attraction cues associated with tachinid pollination: insights from colour variation in Succisella microcephala (Caprifoliaceae)

open access: yesJournal of Pollination Ecology
Pollination syndromes describe convergent floral traits linked to specific pollinator groups. While conceptually useful, the application of this framework to diverse insect assemblages, such as Diptera, remains challenging due to their functional ...
