Mapping an invasive grass in the northwestern US with fused satellite time series and biophysical features

open access: yesEcological Informatics
The introduction and spread of the invasive annual grass Ventenata dubia (ventenata) has incited concern from land managers in the Inland Northwestern United States.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Land surface phenology from SPOT VEGETATION time series

open access: yesRevista de Teledetección, 2016
Land surface phenology from time series of satellite data are expected to contribute to improve the representation of vegetation phenology in earth system models.

Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

What is driving the phenology across the Amazon? A benchmark for land-surface models [PDF]

open access: yes, 2010
We present a study which has used a Fourier-based time-series analysis method applied to 8 years of EO-derived observations of phenology (vegetation indices) and their potential drivers (downward shortwave radiation and precipitation).

Major trends in the land surface phenology (LSP) of Africa, controlling for land-cover change [PDF]

open access: yesInternational Journal of Remote Sensing, 2018
Monitoring land surface phenology (LSP) trends is important in understanding how both climatic and non-climatic factors influence vegetation growth and dynamics. Controlling for land-cover changes in these analyses has been undertaken only rarely, especially in poorly studied regions like Africa.

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

open access: yesBiological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

An Empirical Assessment of the MODIS Land Cover Dynamics and TIMESAT Land Surface Phenology Algorithms [PDF]

open access: yesRemote Sensing, 2019
Observations of vegetation phenology at regional-to-global scales provide important information regarding seasonal variation in the fluxes of energy, carbon, and water between the biosphere and the atmosphere. Numerous algorithms have been developed to estimate phenological transition dates using time series of remotely sensed spectral vegetation ...

Managing for resilience with ecological structure: Portfolio effects in the Laurentian Great Lakes

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Combined effects of global change, including land conversion, biological invasions, and overexploitation, have degraded the resilience of ecosystems and the services they provide. Here, we identify key ecological structures and processes that can be targeted by management to improve resilience at scales ranging from single species to entire landscapes.

Interactions between urban vegetation and surface urban heat islands: a case study in the Boston metropolitan region

open access: yesEnvironmental Research Letters, 2016
Many studies have used thermal data from remote sensing to characterize how land use and surface properties modify the climate of cities. However, relatively few studies have examined the impact of elevated temperature on ecophysiological processes in ...
