American Journal of Botany, EarlyView.Abstract Premise In edaphic old‐growth grasslands, the low nutrient content of the soil restricts plant species establishment. Additionally, fire remains an important factor in shaping vegetation structure and belowground biomass investment in old‐growth grasslands, such as the campos rupestres.

American Journal of Botany, EarlyView.Abstract Premise Rainforests are usually too wet to burn, acting as natural barriers to fire spread and as refuges for biodiversity. However, climate change is increasing the risk of fire incursion into rainforests. Our capacity to manage these impacts is hindered by limited research on rainforest flammability.

Toward a functional understanding of novel fire regimes in tropical forests
American Journal of Botany, EarlyView.Abstract Climate change and land‐use alterations are driving forest fires to unprecedented frequencies and intensities worldwide. Even wet tropical forests—historically rarely subjected to fire—are increasingly experiencing fire disturbances. The impact of wildfires on these forests is likely large, since many of their tree species are not adapted to ...

Applications in Plant Sciences, EarlyView.Abstract Premise Stable transformation is the biggest barrier to studying gene function in plants. In most species, transformation requires tissue culture and regeneration methods that may be arduous and cause undesirable genetic changes. Floral dip methods bypass these challenges by directly transforming ovules of developing flowers, but these methods

Drought and Civil War in Sub-Saharan Africa [PDF]
In this paper, we show that drought has a positive effect on the incidence of civil war over the 1945-2005 period in Sub-Saharan Africa. We use the Palmer Drought Severity Index which is a richer measurement of drought than the measures used in the ...

Animal Research and One Health, EarlyView.We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market
