Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1116-1131, July 2026.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Exploring the legal, policy, ethical and practical implications of digitisation of botanical and fungal collections

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1076-1086, July 2026.
Societal Impact Statement Dried plant and fungal specimens held in collections provide a unique asset to understand the natural world and inform conservation approaches. By creating freely available, digital images of these collections, these specimens can be used by more scientists from around the globe to ask research questions and apply new ...

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, Volume 168, Issue 3, Page 972-984, July 2026.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

open access: yesJournal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

The Franciscana (Pontoporia blainvillei) in the Northern Limit of the FMA II: Strandings and Habitat Use in Ilha Grande Bay

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The presence of the franciscana (Pontoporia blainvillei) at the northern limit of the FMA II was investigated using a range of methods, including monitoring of strandings, boat surveys, and passive acoustic monitoring (PAM). Franciscana strandings were recorded within the distributional gap between Macaé (22°55′ S) and Ilha Grande (23°09′ S ...

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

open access: yesNew Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 568-588, July 2026.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,
