Urbanization, environmental stabilization and temporal persistence of bird species: A view from Latin America [PDF]

open access: yes, 2018
Background. A scarcely studied consequence of urbanization is the effect of temporal stabilization of the environment on bird communities. This alteration is thought to dampen environmental variations between day and night, seasons and years, promoting a

Long‐term population dynamics of western tent caterpillars: History, trends and causes of cycles

open access: yesJournal of Animal Ecology, EarlyView.
The length and in‐depth nature of this population study make it unique. It represents perhaps the most extensive monitoring of viral infection in a wild insect population. We have used laboratory and field experiments to test many hypotheses about mechanisms that potentially impact the dynamics of this cyclic species.

Riparian shading controls instream spring phytoplankton and benthic diatom growth [PDF]

open access: yes, 2016
Dissolved oxygen (DO) concentrations showed a striking pattern in a multi-year study of the River Enborne, a small river in SE England. In each of three years (2010-2012), maximum DO concentrations were attained in mid-April, preceded by a period of ...

Emerging trend of increasing spring frost damage for beech at higher elevations in the Jura Mountains: evidence from tree‐ring data

open access: yesNew Phytologist, EarlyView.
Summary Late spring frost (LSF) severely impacts tree growth and forest productivity, with global warming potentially altering LSF risk due to asymmetric changes in vegetation onset and frost timing. However, reconstructing past frost regimes with climatic and phenological data remains challenging. Using phenological models, high‐resolution climate and

Distinct Molecular Biomechanical Mechanisms Inhibit Endosperm Cell‐Wall Weakening and Seed Germination at Cold and Warm Nonoptimal Temperatures

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Temperature sensing to adjust developmental rates and phenological responses to different climatic environments is critical for plant survival. Population‐based thermal‐time threshold models predict linear relationships between temperature and, for example, seed germination rates (speed), but the mechanisms are not known.

Major QTL with pleiotropic effects controlling time of leaf budburst and flowering-related traits in walnut (Juglans regia L.)

open access: yesScientific Reports, 2020
Breeding studies in walnut (Juglans regia L.) are usually time consuming due to the long juvenile period and therefore, this study aimed to determine markers associated with time of leaf budburst and flowering-related traits by performing a genome-wide ...

Green-Up Protocol [PDF]

open access: yes, 2003
The purpose of this resource is to observe plant green-up and report data that will be used by scientists to validate satellite estimates of the beginning of the plant growing season.

Ecological effects of artificial light at night on wild plants [PDF]

open access: yes, 2016
PublishedSummary 1.Plants use light as a source of both energy and information. Plant physiological responses to light, and interactions between plants and animals (such as herbivory and pollination), have evolved under a more or less stable regime of ...

Physiological Responses of a Desert Phreatophyte to Spatial and Temporal Variation in Groundwater Depth and Vadose Zone Water Availability

open access: yesEcohydrology, Volume 18, Issue 6, September 2025.
ABSTRACT Desert plant responses to changing water resources and atmospheric conditions strongly influence ecosystem carbon and water fluxes. Yet, resolving desert plant responses to spatial and temporal variability in the environment remains challenging. Here, we determined responses of a deep‐rooted phreatophyte shrub (Sarcobatus vermiculatus) growing

Near-surface remote sensing of spatial and temporal variation in canopy phenology [PDF]

open access: yes, 2009
There is a need to document how plant phenology is responding to global change factors, particularly warming trends. “Near-surface” remote sensing, using radiometric instruments or imaging sensors, has great potential to improve phenological monitoring ...
