Evaluation of pollen production in Bromus catharticus Vahl and Guadua trinii (Nees) Nees ex Rupr. (Poaceae) for interpretation of fossil data

Biotemas, 2016
We evaluated pollen production per anther, per flower, and per spikelet of the grassland species Bromus catharticus and the forest taxon Guadua trinii (Poaceae), which have divergent pollination syndrome.

Crop landrace conservation, status, challenges and motivations in Great Britain

PLANTS, PEOPLE, PLANET, EarlyView.
Recent agricultural intensification has led to the widespread replacement of genetically diverse crop landraces with high‐yielding but genetically uniform modern cultivars, reducing the adaptive resilience of farming systems. In the United Kingdom, where large‐scale agriculture dominates, landraces require urgent conservation action.

First automatic size measurements for the separation of dwarf birch and tree birch pollen in MIS 6 to MIS 1 records from Northern Germany

Ecology and Evolution
During past glacial periods, the land cover of Northern Eurasia and North America repeatedly shifted between open steppe tundra and boreal/temperate forest.

Rapid Swelling of Pollen Grains in Response to Floret Opening Unfolds Anther Locules in Rice (Oryza sativa L.)

Plant Production Science, 1999
The changes in pollen grain diameter were examined in relation to the floret opening and anther dehiscence in rice (Oryza sativa L.). In the first experiment, the florets were artificially opened by excising the top of the glumes at various times before ...

Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

Pest Management Science, EarlyView.
Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

Pest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

VARIABILIDAD EN RASGOS POLINICOS EN EL COMPLEJO MIMULUS LUTEUS L. (PHRYMACEAE) EN CHILE CENTRAL VARIABILITY OF POLLEN TRAITS IN THE MIMULUS LUTEUS L. (PHRYMACEAE) COMPLEX IN CENTRAL CHILE

Gayana: Botanica, 2004
We quantified the variability of pollen morphology and life history traits among three natural populations of two taxa in the Mimulus luteus complex and a group of putative hybrids that coexist in the Andean ranges of central Chile.
