Latitude effect on the development of photoperiodic sensitive sorghum [PDF]

open access: yes, 2011
Matching phenology with favourable abiotic and biotic conditions is a prerequisite for good varietal adaptation. That is particularly important in a context of climate change because the temperature increase is likely to modify the precocity of the ...

Species richness, abundance and phenology of fungal fruit bodies over 21 years in a Swiss forest plot [PDF]

open access: yes, 2001
Fungal fruit bodies were surveyed on a plot area of 1500 m2 from 1975¿99 (excluding 1980¿83) in the fungal reserve La Chaneaz in western Switzerland. Fruit bodies were identified and counted on a weekly basis.

Combining thermal and hydric constraints for spatially predicting the activity suitability of Neotropical Leptodactylid frogs

open access: yesEcography, EarlyView.
Amphibians balance their thermal and water budgets depending on their physiological state and the physical environment, with both factors capable of constraining activity. Most mechanistic assessments emphasize thermal over water constraints, potentially missing important aspects of amphibian ecophysiological patterns.

Sustaining Science Infrastructure Is Difficult; Is Commercialization the Answer? The USA National Phenology Network's Experience

open access: yesPerspectives of Earth and Space Scientists
Biological and physical science infrastructure programs play a critical role in supporting scientific discovery. Even with their foundational roles in the process of science, frequently, support for these programs is threatened, reduced, or eliminated ...

The mechanisms of phenology: the patterns and processes of phenological shifts

open access: yesEcological Monographs, 2018
AbstractSpecies across a wide range of taxa and habitats are shifting phenological events in response to climate change. While advances are common, shifts vary in magnitude and direction within and among species, and the basis for this variation is relatively unknown. We examine previously suggested patterns of variation in phenological shifts in order

Studying interspecific population synchrony: current status and future perspectives

open access: yesEcography, EarlyView.
Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

Understanding earwig phenology in top fruit orchards [PDF]

open access: yes, 2008
Earwigs, Forficula auricularia, are key generalist predators to a variety of orchard pests. However, numbers of earwigs have declined in both organic and IPM orchards in recent years. Both Integrated and Organic fruit growers have tried to re-establish
