Begonia quadricornualata sp. nov. (Begoniaceae) from India

Nordic Journal of Botany, EarlyView.
A new species of Begonia L. (Begoniaceae) belonging to sect. Platycentrum is described from the Papum Pare District of Arunachal Pradesh, India. This new species is distinguished by its dense, long, red to brown hispid hairs on the adaxial leaf surface of female plants, caducous stipules and bracts, and solitary‐flowered female inflorescence ...

Policy options for addressing the high cost of specialty pharmaceuticals

Global Health Journal, 2019
The cost to U.S. consumers of specialty drugs is too high, and cost-sharing obligations are reducing patient access to affordable and life-changing medications. While accounting only for approximately 2% of prescriptions filled, specialty drugs accounted

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Managing climate overshoot: a risk-based strategy for climate stabilisation

Frontiers in Climate
Global warming is accelerating, yet current climate strategies centred on emissions reduction and carbon removal are unlikely to prevent temperatures from crossing dangerous tipping points.

Partial recovery of large seed arrival following ecological restoration in fragmented tropical rainforests

Oikos, EarlyView.
Forest restoration success depends crucially on the reinitiation of ecological processes such as seed arrival that drive natural regeneration. We know little about whether, by increasing and diversifying local seed sources to alleviate seed limitation, and attracting animal frugivores to alleviate dispersal limitation, restoration could shift seed ...

The increase of an allelopathic and unpalatable plant undermines reindeer pasture quality and current management in the Norwegian tundra

Communications Earth & Environment
Ongoing Arctic greening can increase productivity and reindeer pasture quality in the tundra. However, greening may also entail proliferation of unpalatable species, with consequences for pastoral social-ecological systems.

Reindeer grazing induces spatial and functional shifts in root systems of boreal pine forests

Oikos, EarlyView.
The spatial distribution of roots, laterally and vertically, is critical for nutrient and water uptake and for driving root‐associated carbon inputs and turnover. Large herbivores, such as reindeer, influence ecosystems belowground by altering aboveground vegetation composition and soil microclimate.

Trait‐associated pathway links plant diversity to litterfall phenology in a seasonally dry tropical forest

Oikos, EarlyView.
Phenology plays a central role in regulating energy flow and nutrient cycling, yet remains insufficiently integrated into biodiversity–ecosystem functioning frameworks. This gap is especially relevant in strongly seasonal systems, where community‐wide synchrony in leaf litterfall may arise from either temporal niche differentiation among species or ...

Tuberculosis: a medical evergreen [PDF]

Acta Radiologica, 2015
Tuberculosis was once believed to be a hereditary disease and the cause of death in 25% of the population in Europe in the 17th century. The American physician and poet Oliver Wendell Holmes called it the white plague and the English writer Charles Dickens described it as a disease which medicine never cured.
