Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

Do Laboratory‐Reared Flies Perform Differently as Pollinators? Morphology, Behaviour and Pollination Performance of Eristalis tenax (Syrphidae)

open access: yesJournal of Applied Entomology, Volume 150, Issue 6, Page 716-727, July 2026.
ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Maximum Lifetime of the Vegetative Biosphere

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract We use a three‐dimensional model to calculate steady‐state climates at various intervals in Earth's future, across a parameter space of increasing insolation and decreasing CO2 ${\text{CO}}_{2}$ mixing ratio. Comparison with prior results shows an overestimation of warming by one‐dimensional models when solar constant is increased and CO2 ...

The Wonders of Vanilla: Celebrating the 150th Anniversary of Synthetic Vanillin

open access: yesChemFoodChem, Volume 2, Issue 2, June 2026.
The year 2024 marked the 150th anniversary of the first commercial production of vanillin, one of the world's most cherished flavor ingredients. This review traces vanilla's history from Mesoamerica to modern production methods, examines its composition, the discovery of vanillin and Haarmann's early synthesis compared to modern methods, and highlights

Wallace's pARCs—Making Climate, Climate Change and Biodiversity Data Available to Protected Area Managers and Conservation Planners With an Example From Biebrza National Park, Poland

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
A spatial representation of the potential ‘adaptation effort’ that might be needed to maintain at least 75% of the species modelled in Biebrza National Park, Poland (white outline), at 1.5°C. The darker the green shading, the less adaptation would be needed.
