How digitisation of herbaria reveals the botanical legacy of the First World War
PLANTS, PEOPLE, PLANET, EarlyView.Digitisation of herbarium collections is bringing greater understanding to bear on the complexity of narratives relating to the First World War and its aftermath – scientific and societal. Plant collecting during the First World War was more widespread than previously understood, contributed to the psychological well‐being of those involved and ...

Wassily Leontief and Léon Walras: the Production as a Circular Flow [PDF]
Leontief’s input-output models are usually viewed as simplified classical (neo-Ricardian) models. However, this interpretation hides two opposed views. On the one hand, the common interpretation, based on Koopmans and Samuelson’s works, considers the so ...

Suhrawardi's Modal Syllogisms [PDF]
, 2012 Suhrawardi’s logic of the Hikmat al-Ishraq is basically modal. So to understand his modal logic one first has to know the non-modal part upon which his modal logic is built. In my previous paper ‘Suhrawardi on Syllogisms’(3) I

PLANTS, PEOPLE, PLANET, EarlyView.This study examines how the fruits of non‐photosynthetic forest plants in the Monotropoideae (Ericaceae) have evolved into the diversity observed today. By analyzing four Asian species, we identified a shift from dry, dehiscent fruits that release seeds into the air to fleshy, berry‐like fruits adapted for animal dispersal.

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree
PLANTS, PEOPLE, PLANET, EarlyView.Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Sustainable Development, EarlyView.ABSTRACT This study pursues a dual objective. First, it investigates the unconditional impact of anti‐globalization on structural transformation in Africa. Second, it explores how environmental degradation interacts with anti‐globalization to influence structural transformation. The analysis focuses on 52 African countries over the period 2005–2023. To

Sustainable Development, EarlyView.ABSTRACT This study investigates how green and non‐green goods, energy transition, digitalization, economic growth, and population affect the material footprint of G‐7 countries from 1990 to 2023. Using an extended STIRPAT framework, we show that green and non‐green goods increase material footprint, demonstrating the resource intensity associated with
