Connecting the geographical occurrence of a species with underlying environmental variables is fundamental for many analyses of life history evolution and for modeling species distributions for both basic and practical ends. However, raw distributional information comes principally in two forms: poi…

Cannabis sativa L. is an important yet controversial plant with a long history of recreational, medicinal, industrial, and agricultural use, and together with its sister genus Humulus, it represents a group of plants with a myriad of academic, agricultural, pharmaceutical, industrial, and social int…

Background The knowledge of distributional dynamics of living organisms is a prerequisite for protecting biodiversity and for the sustainable use of biotic resources. Clematis sect. Fruticella s. str. is a small group of shrubby, yellow-flowered species distributed mainly in arid and semi-arid areas…

Aim: Historically, biomes have been defined based on their structurally and functionally similar vegetation, but there is debate about whether these similarities are superficial, and about how biomes are defined and mapped. We propose that combined assessment of evolutionary convergence of plant fun…

Shifts in species distributions have been documented in response to recent climatic change, with most species moving poleward and to higher altitude. However, different taxa may respond to climatic change differently. The Climatic Variability Hypothesis (CVH) suggests that taxa originating from envi…

Trichophoreae is a nearly cosmopolitan Cyperaceae tribe that contains ∼17 species displaying striking variation in size, inflorescence complexity, and perianth morphology. Although morphologically distinct, the status of its three genera (Cypringlea, Oreobolopsis and Trichophorum) are controversial …

Aim: To fill critical knowledge gaps with regard to the distributions and conservation status of the wild relatives of chile peppers (Capsicum L.). Location: The study covered the potential native ranges of currently recognized wild Capsicum taxa, throughout the Americas. Methods: We modelled the po…

Within the morphologically diverse pantropical genus Phyllanthus, many subgenera, sections and subsections are recognized. While most taxonomic revisions often focus on local floras, closely related and often resembling species are not always treated in full. Subgenus Macraea is here revised for the…

The fossil record of Pyrenacantha (Phytocreneae tribe, Icacinaceae) includes well-documented species from the Paleogene of North and South America but, to date, no fossils have been described from its present geographic range, the Old World tropics. We document endocarp remains from the early Oligoc…

In addition to their potential against deforestation and climate change, agroforestry systems may have a relevant role in biodiversity conservation. In this sense, not only species richness per se, but also community composition, including the distribution range of the species, should be considered.…
