Differences in plant cover and species composition of semiarid grassland communities of central Mexico and its effects on net ecosystem exchange [PDF]
Biogeosciences, 2013 Changes in land use across the semiarid grasslands of northern Mexico have driven a decline of plant cover and alteration of plant species composition. A number of different plant communities have resulted from these changes. Their implications, however,

On the importance of balancing selection in plants [PDF]
New Phytologist, 2013 SummaryBalancing selection refers to a variety of selective regimes that maintain advantageous genetic diversity within populations. We review the history of the ideas regarding the types of selection that maintain such polymorphism in flowering plants, notably heterozygote advantage, negative frequency‐dependent selection, and spatial heterogeneity ...

An Analysis of the Altitude Impact on Roots Compressor Operation for a Fuel Cell System
Applied SciencesHydrogen fuel cell vehicles are one of the most promising alternatives to achieve transport decarbonization targets, thanks to their moderately high efficiency and low refueling time, combined with their zero-exhaust-emission operation. In order to reach

Short-term growth and biomechanical responses of the temperate seagrass Cymodocea nodosa to CO2 enrichment [PDF]
, 2017 Seagrasses are often regarded as climate change 'winners' because they exhibit higher rates of photosynthesis, carbon fixation and growth when exposed to increasing levels of ocean acidification.

Microbial carbon mineralization in tropical lowland and montane forest soils of Peru [PDF]
, 2016 Climate change is affecting the amount and complexity of plant inputs to tropical forest soils. This is likely to influence the carbon (C) balance of these ecosystems by altering decomposition processes e.g., "positive priming effects" that accelerate ...
