Forest phenoclusters for Argentina based on vegetation phenology and climate
(Wiley, 2022-04-01)Forest biodiversity conservation and species distribution modeling greatly benefit from broad-scale forest maps depicting tree species or forest types rather than just presence and absence of forest, or coarse classifications. ... -
Advances in Legume Systematics 14. Classification of Caesalpinioideae. Part 2: Higher-level classification
(Pensoft Publishers, 2024-04-03)Caesalpinioideae is the second largest subfamily of legumes (Leguminosae) with ca. 4680 species and 163 genera. It is an ecologically and economically important group formed of mostly woody perennials that range from large ... -
Integration of a battery of biomarkers to evaluate the health status of field-collected frogs of Leptodactylus luctator living in ecosystems with different anthropogenic disturbances
(Elsevier, 2024-07-10)Amphibians are the most threatened group of vertebrates because they have certain biological and ecological characteristics that make them sensitive to environmental changes. The aim of this study was to evaluate the health ... -
Facing climate change: Range dynamics and chromosome diversity in Hedeoma multiflora benth, a South American aromatic - medicinal plant at risk
(Elsevier, 2024-04-25)Climate change could significantly affect the geographic distribution of plant species. Hedeoma multiflora is a vulnerable medicinal and aromatic herb that distributes in the Pampa, Espinal and Chaco biogeographic provinces ... -
Response to heat stress and glutenins allelic variation effects on quality traits in durum wheat
(Wiley, 2024-01-16)In the context of climate change, high temperature is one of the main abiotic stresses hampering durum wheat production. Through the characterization of an international panel of 271 genotypes, this study investigates the ... -
