Ricerche sulla biologia di Arbutus unedo L. (Ericaceae) sviluppo e struttura del fiore e del frutto [PDF]
In this paper different aspects of Arbutus unedo floral morphology were taken into consideration. The bud development was followed from its formation until antesis.

Yes, we CAM! First evidence of CAM photosynthesis in a carnivorous plant
Evidence for weak, facultative CAM is reported for the first time in a carnivorous plant, i.e., in Mexican representatives of Pinguicula (Lentibulariaceae). Abstract Crassulacean acid metabolism (CAM) is a photosynthetic adaptation enabling higher CO2 concentration close to Rubisco and increased water use efficiency.

The continued investigation of the middle Miocene palynoflora from the Lavanttal Basin reveals numerous additional angiosperm taxa. The Myrtales to Ericales pollen record documented here comprises 46 different taxa belonging to Onagraceae (Ludwigia ...

The phylogenetic distance among species in a community (community phylogenetic structure) has been used to infer deterministic and stochastic assembly processes, albeit with criticisms. The effect of phylogenetic scale (old versus young lineages) and spatial scale on measures of CPS are rarely tested simultaneously, especially in the boreal biome, yet ...

Types and the importance of symbioses in plants [PDF]
Simbioza u užem smislu označava zajednicu dva organizma od koje oba imaju koristi. U biljaka je simbioza s mikroorganizmima u tlu izrazito značajna kao jedan od mehanizama koji im omogućava opstanak u uvjetima manjka vode i nekih mineralnih tvari. Dva su

Variation in leaf morphology is correlated with environmental variables, such as precipitation, temperature and soil composition. Several studies have pointed out that individual plasticity can largely explain the foliar phenotypic differences observed ...

Summary Floral zygomorphy, or monosymmetry, is thought to have a positive effect on the diversification rates of angiosperms, but its true impact is still an open topic. Given the controversy surrounding this matter, our study evaluates whether rewards such as nectar and pollen produced by floral structures evolve in correlation with floral symmetry ...

Global variability in hydraulic traits and water use strategies of mountain shrubs and dwarf shrubs
Shrubs show a wide range of hydraulic strategies to achieve a balanced and favourable water status in mountain areas. Abstract Shrubs are perennial, multi‐stemmed woody plants whose adaptation to stress factors allows them to colonise extreme habitats, including high elevations. Accordingly, shrubs are one of the most important growth forms in mountain
