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

open access: yesEcology 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.

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

open access: yesPLANTS, 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.

Pollen morphology of Nothofagus (Nothofagaceae, Fagales) and its phylogenetic significance

open access: yesActa Palaeobotanica, 2016
Nothofagaceae (southern beeches) are a relatively small flowering plant family of trees confined to the Southern Hemisphere. The fossil record of the family is abundant and it has been widely used as a test case for the classic hypothesis that Antarctica,

Genomic Offset Analyses: Mind Your Climate Variables

open access: yesGlobal 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.

Relationships among livestock, structure, and regeneration in Chilean Austral Macrozone temperate forests

open access: yesTrees, Forests and People, 2023
A Macrozone is a socioecological region with shared geographic and demographic characteristics. Within the Chilean Austral Macrozone (43° to 56° SL), the native temperate forests serve as a crucial resource, offering multiple ecosystem services to local ...

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

open access: yesNew 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

open access: yesEnvironmental 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 ...

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

open access: yesForest 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 ...
