Landscape and environmental heterogeneity support coexistence in competitive metacommunities

Andrea Rinaldo, Giorgio Nicoletti

Metapopulation models have been instrumental in quantifying the ecological impact of landscape structure on the survival of a focal species. However, extensions to multiple species with arbitrary dispersal networks often rely on phenomenological assumption ...

Extracting flowering phenology from grassland species mixtures using time-lapse cameras

Christoph Bachofen

Understanding the impacts of climate change on plant phenology is crucial for predicting ecosystem responses. However, accurately tracking the flowering phenology of individual plant species in grassland species mixtures is challenging, hindering our abili ...

Economic and commercial analysis of reusing dam reservoir sediments

Anton Schleiss

Improper use of chemical fertilizers has led to land degradation. Organic crops, which are farmed using organic fertilizers to reduce the negative environmental effects, are considered an alternative solution to develop the ecosystem health and improve the ...

The effects of previous summer drought and fertilization on winter non-structural carbon reserves and spring leaf development of downy oak saplings

Yue Yang Teo

It is still unknown whether the previous summer season drought and fertilization will affect the winter non-structural carbohydrate (NSC) reserves, spring leaf development, and mortality of trees in the next year. We, therefore, conducted an experiment wit ...

Canopy dieback and recovery in Australian native forests following extreme drought

Alice Jacqueline Frédérique Gauthey

In 2019, south-eastern Australia experienced its driest and hottest year on record, resulting in massive canopy dieback events in eucalypt dominated forests. A subsequent period of high precipitation in 2020 provided a rare opportunity to quantify the impa ...

Responses of plant leaf economic and hydraulic traits mediate the effects of early- and late-season drought on grassland productivity

Alexandre Buttler, Pierre Rémi Mariotte, Constant Signarbieux, Amarante Vitra

Drought can occur at different times during the grassland growing season, likely having contrasting effects on forage production when happening early or later in the season. However, knowledge about the interacting effects of the timing of drought and the ...
