Questions: Woody encroachment is a complex ecological phenomenon, which modifies the composition and diversity of species, productivity, carbon storage and cycling, water dynamics, among others. In Argentina’s semiarid ...

A field experiment was conducted in a temperate semi-arid grassland of central Argentina to test the hypothesis that decomposition of and nutrient release from leaf litter and roots are faster in Poa ligularis and Stipa ...

Increasing global food demand requires the exploration of agricultural production systems that minimise the conflict between food production and biodiversity conservation. Cattle ranching is a main land-use in tropical and ...

To examine whether the critical leaf N ⁄ P ratios (of 14, 16) are valid to test nutrient limitation in the context of semi-arid sandy grasslands, an experiment was conducted on a Keerqin sandy grassland in North-east China ...

Variation in fire intensity affects the post-fire survival and growth of shrubs. We examined effects of maximum fire temperature (a proxy for fire intensity) on the survival, growth and reproductive performance of the ...

An untested theory states that C4 grass seeds could germinate under lower water potentials (Ψ) than C3 seeds. We used hydrotime modelling to study seed water relations of C4 and C3 Canadian prairies grasses to address both ...

Grasslands comprise 85% of Southern Patagonia land area and play a critical role in the global carbon cycle. We evaluated seasonal dynamics to identify differences in soil respiration rates between contrasting grasslands ...

Facilitation may contribute to conserving natural systems disturbed by humans. We hypothesized that the unpalatable native weed, Baccharis ulicina (Baccharis) protects palatable plants from cattle grazing in central Argentina ...
