Cartarea teritoriului României în raport cu lungimea medie a perioadelor de secetă şi uscăciune [Mapping of the Romanian teritory in relation with the average lenght of periods with drought and aridity] [PDF]

Bucovina Forestieră, 2002
The knowledge of natural risk of occurrence of drought period represents a necessity for the foun­dation of afforests technologies and silvicultural operations. The idea of synthesis is in the book of H.

Temporal intraspecific trait variability drives responses of functional diversity to interannual aridity variation in grasslands

Ecology and Evolution, 2019
Interannual climate variation alters functional diversity through intraspecific trait variability and species turnover. We examined these diversity elements in three types of grasslands in northern China, including two temperate steppes and an alpine ...

Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex

American Journal of Botany, EarlyView.
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants

American Journal of Botany, EarlyView.
Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

Applications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Testing the divergence of selected taxa of genus Cotoneaster, Juniperus, Picea and Viburnum - the influence of climate changes on intensive roof gardens

Horticultural Science, 2007
The research has been conducted in several phases for 10 years on existing intensive roof gardens in the Trencin district. The first phase was carried out within the GP 1/4419/47 Adaptability of Cultural Vegetation in Consequence of Global Draining and ...

An artificial neural network–based deep learning model to predict combined stress impact and interaction in plants

Applications in Plant Sciences, EarlyView.
Abstract Premise Plants are frequently exposed to combinations of abiotic and biotic stresses that pose a greater threat to yield and productivity than individual stresses. However, knowledge of the impact of many stress combinations in numerous plants is limited due to the lack of experimental data, which could take decades to generate.

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

PRODUCTIVITY AND NUTRITIVE VALUE OF NATURAL VEGETATION AT WADI-WATEER REGION IN SINAI [PDF]

Arab Universities Journal of Agricultural Sciences, 2009
The present study was carried out in 2004/ 2005 – 2005/2006 seasons to make survey of plant vegetation at Wadi Wateer  (East southern of Sinai) (a bout 100 km length) at 9 successive sites. The study was carried through two years (two wet and dry seasons)
