These images depict drainage canals and roads in peatlands in Borneo, Sumatra, and Peninsular Malaysia at 5 meter resolution. These canals were detected from July-September 2017 Planet Basemaps satellite imagery using a convolutional neural network. Please contact Nathan Dadap (email@example.com) with any questions.
Both diversity and functional composition affect productivity and water use efficiency in experimental temperate grasslandsCharlotte Grossiord, Manuel Walde, Eric Allan, Seraina L. Cappelli, Margaux Didion‐Gency, Arthur Gessler, Marco M. Lehmann & Noémie A. Pichon
Many experiments have shown that biodiversity promotes ecosystem functioning and stability and that this relationship varies with resource availability. However, we still have a poor understanding of the underlying physiological and ecological mechanisms driving diversity effects and how they may interact with soil nutrient availability. We collected data in a grassland experiment factorially manipulating fertilization, species richness, functional composition (slow-growing vs. fast-growing species), and functional diversity in resource economic traits. We measured aboveground productivity, nitrogen...
Climate change exposes ecosystems to strong and rapid changes in their environmental boundary conditions mainly due to the altered temperature and precipitation patterns. It is still poorly understood how fast interlinked ecosystem processes respond to altered environmental conditions, if these responses occur gradually or suddenly when thresholds are exceeded, and if the patterns of the responses will reach a stable state. We conducted an irrigation experiment in the Pfynwald, Switzerland from 2003-2018. A naturally dry...
Phenotypic plasticity versus ecotypic differentiation under recurrent summer drought in two drought-tolerant pine speciesChristoph Bachofen, Anouchka Perret-Gentil, Tom Wohlgemuth, Pierre Vollenweider & Barbara Moser
1. Despite worldwide reports of high tree mortality, growing evidence indicates that many tree species are well adapted to survive repeated dry spells. The drought resilience of trees is related to their phenotypic plasticity and ecotypic differentiation. Whether these two mechanisms act at the same organisational level of a tree and involve similar plant traits is still unknown. 2. We assessed phenotypic plasticity and ecotypic differentiation across four populations of Pinus sylvestris and Pinus nigra...
Dataset: A multi-site, year-round turbulence microstructure atlas for the deep perialpine Lake GardaSebastiano Piccolroaz, Bieito Fernández Castro, Marco Toffolon & Henk Dijkstra
This repository includes the dataset described in "A multi-site, year-round turbulence microstructure atlas for the deep perialpine Lake Garda", Scientific Reports, 2021, DOI: 10.1038/s41597-021-00965-0 A multi-site, year-round dataset comprising a total of 606 high-resolution turbulence microstructure profiles of shear and temperature gradient in the upper 100 m depth is made available for Lake Garda (Italy). Concurrent meteorological data were measured from the fieldwork boat at the location of the turbulence measurements. During the fieldwork campaign...
Some sea slugs are able to steal functional chloroplasts (kleptoplasts) from their algal food sources, but the role and relevance of photosynthesis to the animal host remain controversial. While some researchers claim that kleptoplasts are slowly digestible ‘snacks’, others advocate that they enhance the overall fitness of sea slugs much more profoundly. Our analysis show light-dependent incorporation of 13C and 15N in the albumen gland and gonadal follicles of the sea slug Elysia timida, representing...
The remarkable ecological success of social insects is often attributed to their advanced division of labour, which is closely associated with temporal polyethism in which workers transition between different tasks as they age. Young nurses are typically found deep within the nest where they tend to the queen and the brood, whereas older foragers are found near the entrance and outside the nest. However, the individual-level maturation dynamics remain poorly understood because following individuals over...
Asymmetric divisions that yield daughter cells of different sizes are frequent during early embryogenesis, but the importance of such a physical difference for successful development remains poorly understood. Here, we investigated this question using the first division of C. elegans embryos, which yields a large AB cell and a small P1 cell. We equalized AB and P1 sizes using acute genetic inactivation or optogenetic manipulation of the spindle positioning protein LIN-5. We uncovered that only...
