Microorganisms and soil seed bank in perennial plants

The number of microorganisms in the soil depends on the type of soil, and the influence of microorganisms from the soil can have an inhibitory or stimulatory effect on seed germination. Tests were conducted at three fruit-growing and wine-growing sites.

From Loss to Transformation? Towards Pluralistic and Politicised Agrarian‐Climate Futures

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Understanding how actors perceive and anticipate future states of the world is gaining traction in climate change governance scholarship and related calls for sustainability transformations. However, smallholder farmers, indigenous groups, and local communities, who are expected to bear disproportionate burdens of loss and damage from climate ...

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland

Boreas, EarlyView.
Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

Environmentally adjusted productivity growth and shadow prices for dairy farms

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

Conservation Biology, EarlyView.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Climate shocks, democratization and (a culture of) cooperation

Economica, EarlyView.
Abstract While the direct economic effects of adverse climate shocks are well known, their indirect institutional impact is still poorly understood. To clarify this, we test the idea that adverse climate shocks push time‐inconsistent elites to enact inclusive political institutions, and non‐elites to embrace strong norms of cooperation.

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Seasonality as a structuring factor of the dung beetle community in burned neotropical savannas

Ecological Entomology, EarlyView.
We tested the effects of fire, vegetation cover and seasonality on dung beetle communities, focusing on species richness, composition and co‐occurrence patterns in savannas. Fire did not affect species richness. However, seasonality was the dominant factor influencing species composition, followed by fire and vegetation cover.

Newly identified properties of known pharmaceuticals and myxobacterial small molecules revealed by screening for autophagy modulators

The FEBS Journal, EarlyView.
Autophagy is a cellular degradation process involved in, for example, immune responses to pathogens and neurodegeneration. To identify modulators of autophagy, we developed a microscopy‐based screening assay and identified previously unknown autophagy‐modulating activities in known drugs and natural products from myxobacteria and fungi.
