Bridging the gap from ocean models to population dynamics of large marine predators: A model of mid-trophic functional groups [PDF]

open access: yes, 2009
The modeling of mid-trophic organisms of the pelagic ecosystem is a critical step in linking the coupled physical–biogeochemical models to population dynamics of large pelagic predators. Here, we provide an example of a modeling approach with definitions

Relationship between the Growing Season Maximum Enhanced Vegetation Index and Climatic Factors on the Tibetan Plateau

open access: yesRemote Sensing, 2014
Temperature and water conditions affect vegetation growth dynamics and associated spectral measures. We examined the response of the growing season maximum enhanced vegetation index (MEVI) to the growing season temperature, precipitation, vapor pressure ...

Constraining ecosystem processes from tower fluxes and atmospheric profiles [PDF]

open access: yes, 2011
The planetary boundary layer (PBL) provides an important link between the scales and processes resolved by global atmospheric sampling/modeling and site-based flux measurements.

Early detection of ecosystem regime shifts: A multiple method evaluation for management application [PDF]

open access: yes, 2012
Critical transitions between alternative stable states have been shown to occur across an array of complex systems. While our ability to identify abrupt regime shifts in natural ecosystems has improved, detection of potential early-warning signals ...

Response of Soil C and N, Dissolved Organic C and N, and Inorganic N to Short-Term Experimental Warming in an Alpine Meadow on the Tibetan Plateau

open access: yesThe Scientific World Journal, 2014
Although alpine meadows of Tibet are expected to be strongly affected by climatic warming, it remains unclear how soil organic C (SOC), total N (TN), ammonium N (NH4+-N) , nitrate N (NO3+-N), and dissolved organic C (DOC) and N (DON) respond to warming ...

Coupling low and high trophic levels models: Towards a pathways-orientated approach for end-to-end models [PDF]

open access: yes, 2009
Existing models of marine ecosystems address specific issues related to the bottom-up forcing of production or to the top-down effects of fishing on a limited range of the trophic spectrum.

Does landscape-scale conservation management enhance the provision of ecosystem services? [PDF]

open access: yes, 2014
Biodiversity conservation approaches are increasingly being implemented at the landscape-scale to support the maintenance of metapopulations and metacommunities.

Nonlinear response of ecosystem respiration to multiple levels of temperature increases

open access: yesEcology and Evolution, 2019
Global warming exerts profound impacts on terrestrial carbon cycles and feedback to climates. Ecosystem respiration (ER) is one of the main components of biosphere CO2 fluxes. However, knowledge regarding how ER responds to warming is still lacking.

A conceptual approach to characterizing ecological suitability: Informing socio-ecological measures for restoration effectiveness

open access: yesEcological Indicators, 2022
A combination of ecological and socio-economic outcome indicators is essential for understanding and assessing the effectiveness of the remediation and restoration of degraded ecosystems and revitalizing communities that could benefit from these ...

Response of Soil Respiration to Grazing in an Alpine Meadow at Three Elevations in Tibet

open access: yesThe Scientific World Journal, 2014
Alpine meadows are one major type of pastureland on the Tibetan Plateau. However, few studies have evaluated the response of soil respiration (Rs) to grazing along an elevation gradient in an alpine meadow on the Tibetan Plateau.
