Complex responses of spring vegetation growth to climate in a moisture-limited alpine meadow. [PDF]

open access: yes, 2016
Since 2000, the phenology has advanced in some years and at some locations on the Qinghai-Tibetan Plateau, whereas it has been delayed in others. To understand the variations in spring vegetation growth in response to climate, we conducted both regional ...

RESPONSE OF ALPINE GRASSLAND VEGETATION PHENOLOGY TO SNOW ACCUMULATION AND MELT IN NAMCO BASIN [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Snow/ice accumulation and melt, as a vital part of hydrological processes, is close related with vegetation activities. Taking Namco basin for example, based on multisource remote sensing data and the ground observation data of temperature and ...

Detecting and predicting spatial and interannual patterns of temperate forest springtime phenology in the eastern U.S. [PDF]

open access: yes, 2002
We performed a diagnostic analysis of AVHRR-NDVI and gridded, temperature data for the deciduous forests of the eastern U.S., calibrating temperature accumulation model with satellite data for 1982–1993.

Using by‐catch data from wildlife surveys to quantify climatic parameters and timing of phenology for plants and animals using camera traps

open access: yesRemote Sensing in Ecology and Conservation, 2020
Gaining a better understanding of global environmental change is an important challenge for conserving biodiversity. Shifts in phenology are an important consequence of environmental change.

Natural Enemies of Alfalfa Weevil, \u3ci\u3eHypera Postica\u3c/i\u3e (Coleoptera: Curculionidae), in Minnesota [PDF]

open access: yes, 2017
Alfalfa weevil, Hypera postica, is present throughout Minnesota. How- ever, economically damaging populations seldom occur, due to a combination of natural enemies and adverse climatic conditions.

Plant phenology and seasonal nitrogen availability in Arctic snowbed communities [PDF]

open access: yes, 2006
Thesis (M.S.) University of Alaska Fairbanks, 2006This study was part of the International Tundra Experiment (ITEX) and examined the effects of increased winter snow depth and decreased growing season length on the phenology of four arctic plant species (

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.

Study on the Phenological Changes of Snow and Lake Ice in Qinghai Lake Basin based on MODIS Data

open access: yesGaoyuan qixiang
Phenological changes are of great significance to the study of climate response and ecological environment.Based on the MODIS V6 snow product and reflectivity product in the past 20 years, the snow and lake ice phenology in the Qinghai Lake Basin were ...

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

open access: yesEcography, EarlyView.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.
