Regularized estimation for highly multivariate log Gaussian Cox processes

open access: yes, 2019
Statistical inference for highly multivariate point pattern data is challenging due to complex models with large numbers of parameters. In this paper, we develop numerically stable and efficient parameter estimation and model selection algorithms for a ...

Rates of sustainable forest harvest depend on rotation length and weathering of soil minerals [PDF]

open access: yes, 2014
Removals of forest biomass in the northeastern US may intensify over the coming decades due to increased demand for renewable energy. For forests to regenerate successfully following intensified harvests, the nutrients removed from the ecosystem in the ...

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

open access: yesAdvanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

Retention of harvest residues promotes the accumulation of topsoil organic carbon by increasing particulate organic carbon in a Chinese fir plantation

open access: yesForest Ecosystems
Background: As commonly used harvest residue management practices in subtropical plantations, stem only harvesting (SOH) and whole tree harvesting (WTH) are expected to affect soil organic carbon (SOC) content.

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

open access: yesAdvanced Science, EarlyView.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

Applying trait-based models to achieve functional targets for theory-driven ecological restoration [PDF]

open access: yes, 2014
Manipulating community assemblages to achieve functional targets is a key component of restoring degraded ecosystems. The response-and-effect trait framework provides a conceptual foundation for translating restoration goals into functional trait targets,

Atlantic mammal traits: a dataset of morphological traits of mammals in the atlantic forest of south America [PDF]

open access: yes, 2018
Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species.
