Plant collections: Possibilities of using herbaria, digital herbaria and plant databases in botany teaching at Eszterházy Károly University [PDF]

, 2020
Hagyományosan a herbáriumokat elsősorban kutatók használják, akik egy adott terület növényvilágával foglalkoznak, vagy pedig egy adott rendszertani csoport szakértői, betekintést nyújtva a növényi fajok változatosságába és elterjedésébe.

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

American Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

American Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Placing very long branch taxa in the plant tree of life: A case study with Dioscoreales mycoheterotrophs

American Journal of Botany, EarlyView.
Abstract Premise The inclusion of heterotrophic plants in broader systematic studies is challenging due to substantial morphological modification, gene loss, and accelerated substitution rates following photosynthesis loss. In particular, inclusion of very long branch (VLB) taxa with highly elevated rates may lead to phylogenomic misinference.
