Responses of seasonal indicators to extreme droughts in southwest China [PDF]

, 2020
Significant impact of extreme droughts on human society and ecosystem has occurred in many places of the world, for example, Southwest China (SWC). Considerable research concentrated on analyzing causes and effects of droughts in SWC, but few studies ...

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

, 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 ...

Olive phenology as a sensitive indicator of future climatic warming in the Mediterranean [PDF]

, 2000
Experimental and modelling work suggests a strong dependence of olive flowering date on spring temperatures. Since airborne pollen concentrations reflect the flowering phenology of olive populations within a radius of 50 km, they may be a sensitive ...

Evaluating remote sensing of deciduous forest phenology at multiple spatial scales using PhenoCam imagery [PDF]

, 2014
Plant phenology regulates ecosystem services at local and global scales and is a sensitive indicator of global change. Estimates of phenophase transition dates, such as the start of spring or end of autumn, can be derived from sensor-based time series ...

Spring Phenology of the Boreal Ecosystems [PDF]

, 2020
Ecosystem phenology, i.e., the timing of key biological events, is often considered as both a witness and an actor of climate change. Phenological interannual variations and decadal changes reflect climate variability and trends. Deciduous plant phenology also directly influences the carbon, water, and energy exchanges of the ecosystem with the ...

Observations of Spring Larvae of \u3ci\u3eLycaeides Melissa Samuelis (Lepidoptera: Lycaenidae) in Central Wisconsin [PDF]

, 2017
At 36 sampling sites in central Wisconsin 1991-94, 358 spring larvae of the Karner blue (Lycaeides melissa samuelis) ranged from 1.9-17.0 mm in length, with only two \u3e15.0 mm.

Historical changes in the phenology of British Odonata are related to climate [PDF]

, 2007
Responses of biota to climate change take a number of forms including distributional shifts, behavioural changes and life history changes. This study examined an extensive set of biological records to investigate changes in the timing of life history ...

Spring Bird Migration Phenology in Eilat, Israel

ZooKeys, 2009
Analysis of the mean date of first captures and median arrival dates of spring migration for 34 species of birds at Eilat, Israel, revealed that the earlier a species migrates through Eilat, the greater is the inter-annual variation in the total time of its passage. Birds arrive during spring migration in Eilat in four structured and independent waves.

Weak evidence of provenance effects in spring phenology across Europe and North America

New Phytologist
Forecasting the biological impacts of climate change requires understanding how species respond to warmer temperatures through interannual flexible variation vs through adaptation to local conditions.

Genetic architecture of spring and autumn phenology in Salix [PDF]

BMC Plant Biology, 2014
In woody plants from temperate regions, adaptation to the local climate results in annual cycles of growth and dormancy, and optimal regulation of these cycles are critical for growth, long-term survival, and competitive success. In this study we have investigated the genetic background to growth phenology in a Salix pedigree by assessing genetic and ...
