Major group flowering plants evolving twice quickly temperate zones tropics
2020/7/10
In a surprise twist, a major group of flowering plants is evolving twice as quickly in temperate zones as in the tropics. The finding runs counter to a long-held hypothesis that tropical regions, home...

2017/10/25
Explosive volcanic eruptions in the tropics can lead to El Niño events, those notorious warming periods in the Pacific Ocean with dramatic global impacts on the climate, according to a new study....
The unexpected:Cold snaps in the sub-tropics,drought in rainforests featured at upcoming ecology conference
Cold snaps in the sub-tropics drought rainforests featured ecology conference
2016/7/15
Cold snaps in sub-tropical ecosystems, life under cities in soils, drought in rainforests, and desertification in grasslands are among the topics featured at the 2016 meeting of the Ecological Society...
Policy-making and programme formulation in regard to population, deforestation and other environmental problems in the humid tropics will have to be done in a context of uncertainty. Many facts are un...
Reduced rainfall in the northern tropics linked to industrial emissions, research suggests
Reduced rainfall northern tropics linked industrial emissions research suggests
2015/3/4
Scientists have produced a rainfall record strongly suggesting that man-made industrial emissions have contributed to less rainfall in the northern tropics.
The research team, led by experts at Durha...
Tropical deforestation accounts for almost one-fifth of greenhouse gas emissions and threatens the world’s most diverse ecosystems. Much of this deforestation is driven by illegal logging. We use nove...
Overcoming seasonality in the tropics by growing tomato (Lycopersicon esculentum Mill.) varieties under cooled conditions

The main objective of this work was to overcome seasonality in tomato production under hot tropical summer conditions, as well as to evaluate the adaptability and productivity of cherry and normal siz...
Asymmetric Variation in Soil Carbon Emission in Sub-Tropics
Soil Respiration Carbon Emission Bacterial Abundance
2013/2/26
Carbon dioxide emission from soil, known as soil respiration, is one of the major sources of the atmospheric carbon. Understanding the relationship between emission rate and the factors associated wit...
Long-term effects of management systems on crop yield and soil physical properties of semi-arid tropics of Vertisols
Broadbed and Furrow System Minimum Tillage Long-Term Experiment Sustainability
