Land surface phenology retrievals for arid and semi-arid ecosystems

ISPRS Journal of Photogrammetry and Remote Sensing, 2022
Land surface phenology (LSP) plays a critical role in the regulation of photosynthesis, evapotranspiration, and energy fluxes. Significant progress has been made in extracting LSP information over large areas using satellite data, yet LSP retrievals remain a challenge over vast arid and semi-arid ecosystems because of sparse greenness, high variability

Non‐stationary forest responses to hotter droughts: a temporal perspective considering the role of past legacies

Ecography, EarlyView.
Global change is altering forests worldwide, with multiple consequences for ecosystem functioning. Temporal changes in climate, and extreme, compounded weather events like hotter droughts are affecting the demography, composition and function of forests, leading to a highly uncertain future.

Variability of phenology and fluxes of water and carbon with observed and simulated soil moisture in the Ent Terrestrial Biosphere Model (Ent TBM version 1.0.1.0.0) [PDF]

Geoscientific Model Development, 2015
The Ent Terrestrial Biosphere Model (Ent TBM) is a mixed-canopy dynamic global vegetation model developed specifically for coupling with land surface hydrology and general circulation models (GCMs).

Soil respiration in a northeastern US temperate forest: a 22‐year synthesis [PDF]

, 2013
To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter‐annual variations in soil respiration (Rs), we analyzed more than 100,000 individual measurements of soil ...

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

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.

Human appreciation of flower colours as cultural ecosystem service in grasslands: A methodological approach

Grassland Research, EarlyView.
This literature‐based method estimates human appreciation of flower colours on target grasslands. Step 1: search literature sources (floristic surveys, national floras, web datasets and preference studies). Step 2: flower trait extraction (flower colour and area, flowering period and human colour appreciation scale).

Constraints and Opportunities for Detecting Land Surface Phenology in Drylands

Journal of Remote Sensing, 2021
Land surface phenology (LSP) enables global-scale tracking of ecosystem processes, but its utility is limited in drylands due to low vegetation cover and resulting low annual amplitudes of vegetation indices (VIs).

Mulching Increases Water Use Efficiency, Production and Profitability in Forage Cactus–Maize Intercropping Systems

Irrigation and Drainage, EarlyView.
ABSTRACT This study evaluated the growth, forage production, soil water balance, water indices, biological efficiency and competitive capacity of forage cactus and maize in monoculture and intercropping, with or without mulch. The experiment was conducted in Serra Talhada, Pernambuco, Brazil, using the cactus clone ‘Orelha de Elefante Mexicana’ (OEM ...

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.
