Land surface phenology and biodiversity in Zambian woodlands

Seasonal foliage display (leaf phenology) is a key determinant of ecosystem function. Variation in land surface phenology, observed via space-borne remote sensing, can be explained at broad spatial scales by climate, but we lack understanding of how ...

Aiouea riedeliana comb. nov. (Lauraceae) from Brazil, with an amended description and provisional extinction threat assessment

Nordic Journal of Botany, EarlyView.
Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

Analysis of the land surface heterogeneity and its impact on atmospheric variables and the aerodynamic and thermodynamic roughness lengths [PDF]

, 2008
The land surface heterogeneity has a very significant impact on atmospheric variables (air temperature T-a, wind speed u, and humidity q), the aerodynamic roughness length z(0m), thermodynamic roughness length z(0h), and the excess resistance to heat ...

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

Improving the temporal accuracy of vegetation phenology indicators through the integration of satellite data and high-resolution near-surface camera observations

International Journal of Digital Earth
Satellite-derived land surface phenology (LSP) metrics are widely used to monitor vegetation phenology at large scales. However, current LSP products have uncertainties from limited satellite revisit cycles and adverse weather.

Characterizing Land Cover Impacts on the Responses of Land Surface Phenology to the Rainy Season in the Congo Basin [PDF]

Remote Sensing, 2017
Knowledge of how rainfall seasonality affects land surface phenology has important implications on understanding ecosystem resilience to future climate change in the Congo Basin. We studied the impacts of land cover on the response of the canopy greenness cycle (CGC) to the rainy season in the Congo Basin on a yearly basis during 2006–2013 ...

On the Suitability of MODIS Time Series Metrics to Map Vegetation Types in Dry Savanna Ecosystems: A Case Study in the Kalahari of NE Namibia [PDF]

, 2009
The characterization and evaluation of the recent status of biodiversity in Southern Africa’s Savannas is a major prerequisite for suitable and sustainable land management and conservation purposes.

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

Oikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...

Challenging a Global Land Surface Model in a Local Socio-Environmental System

Land, 2020
Land surface models (LSMs) predict how terrestrial fluxes of carbon, water, and energy change with abiotic drivers to inform the other components of Earth system models.

Spatiotemporal Analysis of Land Surface Plant Phenology

Journal of Agricultural, Biological and Environmental Statistics
Abstract Plant phenology is the study of cyclic and seasonal plant life developmental stages and is used by scientists and policy-makers to understand agricultural management practices, climate change effects, and ecosystem processes.
