Measuring maternal line selection driven by differential survival in ex situ collections for plant conservation

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Ex situ plant collections may be increasingly needed to protect representative samples of threatened or rare species and provide plant material for conservation translocation. A primary problem in these ex situ collections is loss of intraspecific variation due to plant death. Different management actions would be required depending on whether

A review of high nature value farming systems in Europe: Biodiversity, ecosystem services, drivers, innovations and future prospects

People and Nature, Volume 8, Issue 7, Page 2049-2064, July 2026.
Abstract Farming systems of high natural and cultural value represent approximately 30% of farmlands in the European Union and are associated with a high species and habitat diversity and/or the presence of species of European conservation concern. This study aims to synthesize the existing knowledge on the assessment of biodiversity and ecosystem ...

The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1238-1255, July 2026.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

New Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Tolerancia al aluminio en especies vegetales: mecanismos y genes

Universitas Scientiarum, 2013
Agricultural production in the Colombian Orinoco is affected by the high aluminum content found in 4.5 million hectares. Genotypes of different species have acquired different levels of tolerance and signaling pathways through various mechanisms, making a single model impossible.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Exploración del poder antibiótico de especies vegetales mexicanas

JÓVENES EN LA CIENCIA
El proyecto se centra en la búsqueda de fuentes naturales que inhiban el crecimiento bacteriano, particularmente plantas con compuestos bioactivos utilizados históricamente en la medicina tradicional mexicana. Ante el creciente problema de la resistencia antimicrobiana (RAM), se investigaron como actuaban los extractos metanólicos de cinco especies ...
