Forest biogeochemistry in response to drought

Global Change Biology, Journal Year: 2015, Volume and Issue: 22(7), P. 2318 - 2328

Trees alter their use and allocation of nutrients in response to drought, changes soil nutrient cycling trace gas flux (N2 O CH4 ) are observed when experimental drought is imposed on forests. In extreme droughts, trees increasingly susceptible attack by pests pathogens, which can lead major the soil. Extreme droughts often more common intense forest fires, causing dramatic storage loss from ecosystems. Changes future manifestation will affect carbon uptake forests, leading feedbacks Earth's climate system. We must improve recognition nature, our ability manage forests face parameterization earth system models for improved predictions world's

Tropicalization of temperate ecosystems in North America: The northward range expansion of tropical organisms in response to warming winter temperatures

Global Change Biology, Journal Year: 2021, Volume and Issue: 27(13), P. 3009 - 3034

Published: Feb. 19, 2021

Tropicalization is a term used to describe the transformation of temperate ecosystems by poleward-moving tropical organisms in response warming temperatures. In North America, decreases frequency and intensity extreme winter cold events are expected allow poleward range expansion many cold-sensitive organisms, sometimes at expense organisms. Although ecologists have long noted critical ecological role temperature extremes tropical-temperate transition zones, effects been understudied, influence temperatures has too often left out climate change vulnerability assessments. Here, we examine on northward limits diverse group including terrestrial plants, coastal wetland fishes, sea turtles, reptiles, amphibians, manatees, insects. For these can lead major physiological damage or landscape-scale mass mortality. Conversely, absence foster population growth, expansion, regime shifts. We discuss winters species zones. 21st century, change-induced facilitate species. Our review highlights knowledge gaps for advancing understanding implications tropicalization America.

The Threat of the Combined Effect of Biotic and Abiotic Stress Factors in Forestry Under a Changing Climate

Frontiers in Plant Science, Journal Year: 2020, Volume and Issue: 11

Published: Nov. 30, 2020

Plants encounter several biotic and abiotic stresses, usually in combination. This results major economic losses agriculture forestry every year. Climate change aggravates the adverse effects of combined stresses increases such losses. Trees suffer even more from recurrence stress combinations owing to their long lifecycle. Despite effort study damage individual factors, less attention has been given effect complex interactions between multiple stresses. In this review, we assess importance, impact, mitigation strategies climate driven forestry. The ecological importance under different is highlighted by contribution decline global forest area through direct indirect roles loss biodiversity resulting local extinction endangered species trees, emission biogenic volatile organic compounds, reduction productivity quality products services. factors as high temperature drought increase disease insect pest outbreaks, decrease growth cause tree mortality. Reports massive mortality events caused “hotter droughts” are increasing all over world, affecting genera trees including some most important plantation forests, Pine, Poplar, Eucalyptus . While pests, pathogens, parasitic plants have reported be associated with many these events, a considerable number reports not taken into account factors. available also tend undermine interactive Thus, discussion centers on based research innovation, which build models previously used curb
