Climate change and biodiversity
Climate change is triggering similar effects on the incidence and severity of disease for crops in agriculture and wild plants in natural communities. The complexity of natural ecosystems, however, generates a complex array of interactions between wild plants and pathogens in marked contrast to those generated in the structural and species simplicity of most agricultural crops. Understanding the different impacts of climate change on agricultural and natural ecosystems requires accounting for the specific interactions between an individual pathogen and its host s and their subsequent effects on the interplay between the host and other species in the community. Ultimately, progress will require looking past short-term fluctuations to multiyear trends to understand the nature and extent of plant and pathogen evolutionary adaptation and determine the fate of plants under future climate change.

Ecological networks are more sensitive to plant than to animal extinction under climate change
Climate change and variability pose a threat to wildlife resources in semi-arid savannahs. With examples from selected protected areas in Southern Africa, this chapter highlights studies on detected climate changes particularly rainfall and temperature, outlines the predicted and observed impacts of climate change and variability on wildlife resources in savannah ecosystems and highlights the adaptation and mitigation strategies and implications for conservation. Literature indicates that Southern Africa is characterised by highly variable, erratic and unpredictable rainfall and increasing temperature coupled with an increasing trend in climate-related extreme events such as frequent droughts, cyclones and heat waves. Drought, in particular, has led to death in several wildlife species. This has implications on long-term survival of the species.
A changing climate means changing habitats, threatening vulnerable species. On a cold and bitter winter night, in a field of boulders beneath a thick layer of snow, a mountain pygmy possum sleeps safe and snug. Under this white blanket, the mountain pygmy possum can hibernate the winter away. This is just one example of an Australian species that stands to lose its habitat in the face of climate change. The world is heating up. The average temperature of the Earth's surface increased by an estimated 0.
Climate variability and change affects birdlife and animals in a number of ways;. a) Birds lay eggs earlier in the year than usual,. b) Plants bloom earlier and.
Thirsty future ahead as climate change explodes plant growth
Climate change is any significant long term change in the expected pattern, whether due to natural variability or as a result of human activity. Environmental conditions play a key role in defining the function and distribution of plants , in combination with other factors. Changes in long term environmental conditions that can be collectively coined climate change are known to have had enormous impacts on current plant diversity patterns; further impacts are expected in the future.
January 15, Global warming affects more than just plant biodiversity—it even alters the way plants grow.
