Heat tolerance predicts the importance of species interaction effects as the climate changes

Not exact matches

The many different species of plants and animals each have their own particular natures because of a long history of interactions and cause - and - effect sequences which have made each species what it is.

Besides affecting the species themselves, such changes could have wider effects by limiting the movement of nutrients and altering ecological interactions.

The team is currently studying microbial - immune interaction in a more complex context, analyzing the additive effects of several bacterial species at a time.

Ecologists are increasingly realizing that no species exists in a vacuum, but understanding the effects of their interactions can be challenging.

With slow environmental change, the indirect effects of species on the evolution of other species may help mutualistic interactions persist over long periods of time.

On evolutionary time scales, we know far less about the effects of extinction of rare species, but we do know that evolution can amplify the effect of a species over time through its interactions on survival of other species.

Although competitive interactions and species number may have diverse effects on variability measured at the individual species level, a combination of theoretical analyses shows that these factors have no effect on variability measured at the community level.

Therefore, biodiversity may increase community stability by promoting diversity among species in their responses to environmental fluctuations, but increasing the number and strength of competitive interactions has little effect.

These effects can be indirect, via shifts in food availability or species interactions (e.g., predation and competition).

Zoologists often study entire ecosystems, observing the interactions among multiple species and the effects that each has on the other.

«This analysis combines the results of all these experiments to study the combined effects of multiple stressors on whole communities, including species interactions and different measures of responses to climate change.»

-- Incorporation of more aerosol species and improved treatment of aerosol - cloud interactions allow a best estimate of the cloud albedo effect.

In addition, ocean acidification is co-occurring with other drivers of environmental change (including warming, eutrophication, hypoxia, eutrophication, pollution [12]-RRB-, yet the interactive effects and relative importance of multiple stressors on species physiology, life history and ecology, as well as species — environment interactions and ecosystem function remain poorly understood [13 — 17].

Nonetheless, the rapid and often asymmetric growth of this interdisciplinary field has left important knowledge gaps that require urgent attention: (i) what are the effects of ocean acidification and climate change on species interactions?

Finally, the impacts of climate change on plant growth could alter ecological interactions among species with potential cascading effects on food webs; integrating changes in suitable plant growing days and NPP within recently developed General Ecosystem Models [40] could provide some insights into the magnitude of these changes.

Topics that I work on or plan to work in the future include studies of: + missing aerosol species and sources, such as the primary oceanic aerosols and their importance on the remote marine atmosphere, the in - cloud and aerosol water aqueous formation of organic aerosols that can lead to brown carbon formation, the primary terrestrial biological particles, and the organic nitrogen + missing aerosol parameterizations, such as the effect of aerosol mixing on cloud condensation nuclei and aerosol absorption, the semi-volatility of primary organic aerosols, the importance of in - canopy processes on natural terrestrial aerosol and aerosol precursor sources, and the mineral dust iron solubility and bioavailability + the change of aerosol burden and its spatiotemporal distribution, especially with regard to its role and importance on gas - phase chemistry via photolysis rates changes and heterogeneous reactions in the atmosphere, as well as their effect on key gas - phase species like ozone + the physical and optical properties of aerosols, which affect aerosol transport, lifetime, and light scattering and absorption, with the latter being very sensitive to the vertical distribution of absorbing aerosols + aerosol - cloud interactions, which include cloud activation, the aerosol indirect effect and the impact of clouds on aerosol removal + changes on climate and feedbacks related with all these topics In order to understand the climate system as a whole, improve the aerosol representation in the GISS ModelE2 and contribute to future IPCC climate change assessments and CMIP activities, I am also interested in understanding the importance of natural and anthropogenic aerosol changes in the atmosphere on the terrestrial biosphere, the ocean and climate.
