Patagonian Imaginary Nature: Colonial Narratives in Documentary Films on Subnational Spaces (1920–1955)

Bulletin of Latin American Research, EarlyView.
This study contributes to the ongoing historical examination of ecological and postcolonial questions in Latin America through the lens of new media genre narratives. Early 20th‐century documentary films of Argentine Patagonia institutionalised a natural binary opposition, positioning those challenging colonial power relations based on natural ...

What exactly is a family man? Performing and precluding respectable fatherhood in Dominica

Ethos, Volume 53, Issue 2, June 2025.
Abstract How does a father come to be regarded as a “family man” in the Caribbean? By tracking the stories and strivings of various Dominican men who seek recognition as dedicated fathers, this essay unfolds complex answers to this seemingly simple question.

Pollen--tiny and ephemeral but not forgotten: New ideas on their ecology and evolution.

American-Eurasian journal of botany, 2016
Ecologists and evolutionary biologists have been interested in the functional biology of pollen since the discovery in the 1800s that pollen grains encompass tiny plants (male gametophytes) that develop and produce sperm cells.

Genetic and phenotypic responses to habitat fragmentation in a European harvester ant

Insect Conservation and Diversity, EarlyView.
Our work highlights the use of multiple approaches to evaluate species responses to habitat fragmentation. Less allelic richness in habitats with fewer ant nests and reduced heterozygosity with less allelic richness indicated inbreeding; smaller gyne mesosoma size in less connected habitats indicated reduced flight ability.

Pollen limitation is not the rule in nival plants: A study from the European Central Alps.

American-Eurasian journal of botany, 2016
PREMISE OF THE STUDY Seed output of high-mountain plants in the uppermost life zones is highly variable. One possible reason might be pollen limitation due to inadequate pollinator services.

Tropical Biome Switching: Ant Communities Transition From Savanna to Rainforest Following Cessation of Burning

Journal of Biogeography, EarlyView.
ABSTRACT Savannas and rainforests co‐occur as mosaics across large areas of the tropics. These mosaics are dynamic, with savanna and rainforest switching in relatively short time scales, largely through the effects of fire. Most research to date addresses such biome switching through the lens of vegetation, with little attention given to faunal ...

Impact of Mulches on Floral Visitors in Day‐Neutral Strawberries and Contribution of Syrphid Flies to Strawberry Pollination

Journal of Applied Entomology, EarlyView.
ABSTRACT Animal‐mediated pollination is essential for the production of many specialty crops, with insects, primarily bees, serving as the predominant pollinators in many agroecosystems. However, increasing management problems with honey bees and declines in native bee populations due to various environmental stressors have highlighted the importance ...

Ensuring Pollinator Presence in Expanding Oil Crops: The Case of Mystrops debilis (Nitidulidae) and the Macauba Palm (Acrocomia aculeata, Arecaceae)

Journal of Applied Entomology, EarlyView.
ABSTRACT The macauba palm (Acrocomia aculeata, Arecaceae) is a Neotropical native oil palm, increasingly important in Central and South America due to rising demand for raw materials and its potential for bioenergy. Understanding its pollinator ecology is crucial to identify new areas for cultivation. This study examines the structure of floral visitor

Reciprocal regulation between AtFH5‐labeled secretory vesicles and PI(4,5)P2 oscillation at the plasma membrane directs pollen germination

Journal of Integrative Plant Biology, EarlyView.
In Arabidopsis, FORMIN HOMOLOGY PROTEIN 5‐labeled secretory vesicles and phosphatidylinositol 4,5‐bisphosphate (PI(4,5)P2) form a self‐reinforcing loop, where vesicles deliver the phosphatidylinositol 4‐phosphate 5‐kinase AtPIP5K4 to promote PI(4,5)P2 production, which in turn facilitates vesicle attachment to the plasma membrane, highlighting a novel ...
