Climate adaptation and functional constraints drive pollen evolution in Apiales

New Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Fine‐tuning the buzz: comparing visitation frequency and pollination effectiveness in plant–pollinator networks

New Phytologist, Volume 249, Issue 4, Page 2140-2152, February 2026.
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.

Nudez como Estigma

Nhengatu, 2022
O movimento de perseguição e demonização da mulher conhecido como “caça às bruxas”, se estendeu entre o século XV e o século XVIII por toda a Europa. Essa perseguição contra as mulheres acusadas de praticarem bruxaria se intensificou especialmente após a criação do Tribunal do Santo Ofício, que funcionava como uma espécie de tribunal religioso que ...

Floral stage optimization and immune evasion enhance Agrobacterium‐mediated genome editing in Arabidopsis

New Phytologist, Volume 249, Issue 4, Page 2125-2139, February 2026.
Summary Agrobacterium‐mediated transformation by floral inoculation (AMT‐FI) enables genetic engineering without tissue culture. It is widely used in the model plant Arabidopsis thaliana, yet its efficiency and broader applicability remain limited. Here, we used a dual‐reporter system (RUBY and hygromycin resistance) to identify key floral stages and ...

Estigma e saúde

, 2013
Estigma é definido como um atributo negativo ou depreciativo, que torna o sujeito diferente, diminuído ou possuidor de uma desvantagem. Mas o problema vai além: o estigma é também um dos processos sociais que reduzem o acesso à saúde por parte dos indivíduos e grupos afetados.

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Estigma en epilepsia

Iatreia, 2009
El estigma ha acompañado a la epilepsia durante toda la historia, afecta a todas las razas y clases sociales y limita el desarrollo humano de los individuos afectados. El estigma tiene explicaciones antropológicas y psicológicas fuertes, que pueden ser intervenidas para que las personas con epilepsia logren una mejor calidad de vida. La Organización
