Weed Research, Volume 66, Issue 2, March/April 2026.ABSTRACT Grasses in the Poaceae family are major components of global ecosystems and agricultural systems, and their adaptive success has enabled some species to become highly competitive weeds. Digitaria insularis (sourgrass), a C4 perennial grass native to the Americas and now widely introduced elsewhere, has evolved herbicide resistance and poses an

Understanding global climate change scenarios through bioclimate stratification
Environmental Research Letters, 2017 Despite progress in impact modelling, communicating and understanding the implications of climatic change projections is challenging due to inherent complexity and a cascade of uncertainty. In this letter, we present an alternative representation of global climate change projections based on shifts in 125 multivariate strata characterized by relatively

Ecology and Evolution, Volume 16, Issue 2, February 2026.Primula sikkimensis persisted in distinct glacial refugia within the Hengduan Mountains and eastern Himalayas during the Last Glacial Maximum. Subsequent postglacial range expansions onto the Qinghai–Tibet Plateau were accompanied by secondary contact and interspecific hybridization, collectively enhancing genetic diversity and adaptive capacity. These

Macroecología y ecoinformática: sesgos, errores y predicciones en el modelado de distribuciones
Ecosistemas, 2014 Hoy en día es común estudiar los patrones globales de biodiversidad a partir de las predicciones generadas por diferentes modelos de nicho ecológico. Habitualmente, estos modelos se calibran con datos procedentes de bases de datos de libre acceso (e.g ...

The Bioclimates of the Colorado Front Range
Mountain Research and Development, 1985 This paper delineates bioclimatic zones of the Colorado Front Range. It develops a methodology which might be useful for making inventories of mountain bioclimates in other parts of the world. Following a description of the vegetation and the climate of the Front Range some insight is gained into the bioclimatic systems of the area by examining the ...

Climate and bioclimate analysis of Ondo State, Nigeria
Meteorologische Zeitschrift, 2011 Most of the previous analyses of climate of Nigeria, particularly OndoState have been for agricultural use. They have little or no application for biometeorological purposes. This paper examines and analyse the climate of Ondo State, Nigeria with respect to biometeorological parameters based on air temperature, relative humidity, wind speed, solar ...

Revista Chilena de Historia Natural, 2009 Various studies have shown that model performance may vary depending on the species being modelled, the study área, or the number of sampled localities, and suggest that it is necessary to assess which model is better for a particular situation. Thus, in
