Relative Influence of Timing and Accumulation of Snow on Alpine Land Surface Phenology [PDF]

Journal of Geophysical Research: Biogeosciences, 2018
AbstractTiming and accumulation of snow are among the most important phenomena influencing land surface phenology in mountainous ecosystems. However, our knowledge on their influence on alpine land surface phenology is still limited, and much remains unclear as to which snow metrics are most relevant for studying this interaction.

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

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 ...

Breynia phuongiana (Phyllanthaceae), a new species from the Central Highlands of Vietnam

Nordic Journal of Botany, EarlyView.
A new species, Breynia phuongiana (Phyllanthaceae subgen. Sauropus), is described and illustrated from the Central Highlands of Vietnam. It is morphologically similar to B. beillei, B. bonii, and B. thorelii, but differs in having oblong‐elliptic leaves, sepals marked with reddish striations, an androphore exceeding 1 mm in length, and distinctly ...

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.

RECENT trends in the land surface phenology of africa observed at a fine spatial scale [PDF]

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
This research describes the seasonal phenological pattern of Africa's vegetation and its recent trends using MODIS EVI time-series data with a relatively fine spatial resolution of 500 m and a long temporal range of 15 years (2001–2015). The objectives were to measure the vegetation phenology of the major land cover types and determine the temporal ...

Pinguicula brendae (Lentibulariaceae) sp. nov., a carnivorous plant from a tropical montane cloud forest in Hidalgo, Mexico

Nordic Journal of Botany, EarlyView.
A new species of Lentibulariaceae, Pinguicula brendae Rodríguez‐Ramírez, H.Shimai & A.R. Andrés‐Hernández, is described based on its unique morphological characteristics. This species is restricted to limestone rock walls in the San Bartolo Tutotepec municipality, central‐eastern Hidalgo, Mexico, where it inhabits a single locality on vertical, north ...

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.

Update on Ouratea cidiana Sastre (Ochnaceae), a microendemic species from the Amazon: enlightening the identity and conservation status

Nordic Journal of Botany, EarlyView.
Ouratea cidiana (Ochnaceae) is a microendemic shrub species from the Brazilian Amazonia, occurring along the banks of the Trombetas River and restricted to the Cachoeira Porteira region, in western Pará State. Since the original collection nearly forty years ago, no additional records have been made, which is concerning given the continuous decline in ...
