Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

The Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Patterns and environmental drivers of root traits across hydrological gradients in old growth boreal forests

Oikos, EarlyView.
Many key ecosystem functions are affected by plant roots and their traits. However, understanding of the patterns in, and drivers of, root traits lags far behind equivalent knowledge of above‐ground tissues, particularly in boreal old growth forests. We surveyed community‐level root traits across 11 old growth forests spanning a wide latitudinal range ...

Accidental plant poisonings in France: Lessons from a decade of national toxicovigilance

PLANTS, PEOPLE, PLANET, EarlyView.
Accidental plant poisonings reveal how modern societies are losing everyday botanical knowledge once central to food and health safety. By analyzing a decade of French toxicovigilance data, this study shows that most severe cases arise from plant misidentification or misguided self‐medication.

Fusarium oxysporum and F. verticillioides associated with damping-off in Pinus spp.

Revista Ciência Agronômica
Occurrence of Fusarium spp. is one of the problems, most limiting to growth of seedlings, in nurseries. This pathogen can be transmitted via seeds and causes damages to the seedlings during pre- and post-emergence stages.
