Canscora agni (Gentianaceae), a new species from the fire‐prone Indian savannas

Nordic Journal of Botany, EarlyView.
We describe Canscora agni from the Indian savannas as a distinct species which differs from its allied species Canscora alata in having fewer and shorter leaves, pedicel‐wings unequal across the length, bracts with glandular hair on the margins, calyx‐wings being four, wider, up to 2.3 mm, with distinct reticulate venation and having ovary length up to

Historical data reveal earlier flowering under environmental change

Nordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

Strigolactone signaling: Licensing antiviral RNA interference in rice

New Plant Protection, EarlyView.
Rice grassy stunt virus (RGSV) suppresses strigolactone‐mediated antiviral RNAi through P3‐D14 interaction. Structure‐guided D14D102N editing disrupts P3 binding while maintaining SL signaling, sustaining antiviral defense and providing strong resistance without compromising plant growth or yield.

Dynamics of black-grass populations depending on the sowing time of winter wheat

, 2011
Currently, economic, agronomic and environmental concerns, lead to reduce use of herbicides. This reduction can be help by cultural measures like delay of the sowing date. Four sowing dates of winter wheat from 15th of October to 26th of November were tested.

Hunting Strategies and Game Exploitation Organization in the Magdalenian: An Integrated Approach Based on Mortality Profiles and Stable Isotopes at Chaves Cave (Huesca, Spain)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Understanding hunting strategies in Upper Paleolithic contexts remains challenging due to the complex relationships between prey behavior, environmental conditions, and human decision‐making. Addressing these dynamics requires integrating archeozoological, geospatial, and geochemical proxies capable of capturing demographic patterns, landscape

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

Oikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

Oikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.

A tipping point for tipping points

Oikos, EarlyView.
Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

The importance of biodiversity components differs among wood‐based material Nature's contributions to people (NCP) in a tropical montane ecosystem

Oikos, EarlyView.
Biodiversity can influence forest productivity, but this does not necessarily translate into higher provision of wood‐based Nature's contributions to people (NCP), as only a subset of the wood produced is used for each NCP. Biodiversity–NCP relationships therefore require further assessment.

More than proteins for empty stomachs: Wild meat in the BaTonga food system

People and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.
