Impacts of fire severity and cattle grazing on early plant dynamics in old-growth Araucaria-Nothofagus forests

Forest Ecosystems, 2019
Background Fire has historically shaped the dynamics of Araucaria araucana-Nothofagus pumilio forests in the Andean region of South America. Nevertheless, human disturbances and stronger drought events have resulted in increased occurrence and severity ...

A systematic review of observational studies reporting climate change impacts on plant communities in Mediterranean‐type ecosystems

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Mediterranean‐type ecosystems (MTEs) are highly vulnerable to climate change, with drought, wildfire and climate variability (among other disturbances) causing measurable changes in vegetation condition, growth, diversity, physiology and phenology; yet observational studies remain scarce compared to experimental and modelling studies.

Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in Desfontainia fulgens

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

Recovery of Seed Quality and Germination Success Following Severe Wildfires in Araucaria araucana Forests of the Southern Andes

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We assessed post‐fire germination of Araucaria araucana in the southern Andes and found that seed viability and germination increased markedly (from 65% to 90%) between 1 and 8 years after a severe wildfire. Improved germination at longer time‐since‐fire reflects a recovery of reproductive capacity in this ecologically and culturally significant ...

Digitisation as archival intermediary: Quantifying and qualifying Greta B. Stevenson's mycological collector networks

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1275-1291, July 2026.
Mass digitisation of natural science collections and archives has increasingly become a priority for scientific heritage institutions. Here, we explore the potential of mass digitisation to improve our understanding of the nature and history of scientific collaboration. Focusing on mycologist Greta B.

Genomic Offset Analyses: Mind Your Climate Variables

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Recent methods based on genomic offset (GO) statistics aim to quantify the risk of non‐adaptation of populations to future climates. This study assesses how well genomic offset values correspond to population variation in fitness, depending on the methods and climate data used.

Lachnaceae (Helotiales, Leotiomycetes) of New Zealand—An Introduction

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
This is the first of a planned series of articles on the taxonomy and diversity of Lachnaceae (Leotiomycetes, Helotiales) of New Zealand. Based largely on specimens from the New Zealand Fungarium (Te Kohinga Hekaheka o Aotearoa) (PDD) that have DNA sequences available, this paper provides a brief survey of the New Zealand species present in each of the

Functional Diversity and Community Composition of Soil Fungi Associated With Canopy Dieback in Araucaria araucana Forests of Contrasting Edaphic Conditions

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Soil fungal communities associated with Araucaria araucana differ primarily according to site edaphic conditions rather than tree health status. Restrictive, nutrient‐poor soils are linked to higher canopy dieback and distinct functional community shifts, with symptomatic trees harbouring stress‐tolerant taxa and asymptomatic trees supporting ...

Regeneración de un bosque mixto de Nothofagus (Nothofagaceae) después de una corta selectiva Regeneration of a Nothofagus (Nothofagaceae) mixed forest after selective cutting

Revista Chilena de Historia Natural, 2003
El estudio de la ecología de la regeneración natural del bosque constituye una parte esencial de la silvicultura. El cerro Tren Tren (40°12' S, 71°26' O, 1.367 m, Reserva Mapuche Curruhuinca, Argentina) está ocupado por un bosque cerrado compuesto por ...

Variabilidad topográfica y edáfica en bosques de Nothofagus betuloides (Mirb) Blume, en el suroeste de Tierra del Fuego, Chile Edaphic and topographic variability in Nothofagus betuloides (Mirb) Blume forests, in southwestern Tierra del Fuego, Chile

Revista Chilena de Historia Natural, 2007
Se investigó la variabilidad de las relaciones topográficas y edáficas en sitios con presencia de Nothofagus betuloides y especies arbóreas asociadas en el suroeste de Tierra del Fuego. Estas relaciones se analizaron con métodos estadísticos bivariados y
