Seasonal variability of periphyton nutrient status and biomass on artificial and natural substrates in a tropical mesotrophic reservoir Variação sazonal do estado nutricional e da biomassa do perifíton em substrato artificial e natural em um reservatório tropical mesotrófico

open access: yesActa Limnologica Brasiliensia, 2010
AIM: Study aimed at evaluating the periphytic community seasonal variation, nutrient status and biomass on artificial and natural (Nymphaea spp., Utricularia foliosa Linnaeus) substrates at a shallow mesotrophic reservoir (Ninféias Reservoir) located in ...

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

open access: yesJournal of Quaternary Science, Volume 41, Issue 3, Page 520-539, April 2026.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

Pollen Dimorphism of Several Members of Nymphaeaceae and Nelumbonaceae: An Index of Geographical and Ecological Variation

open access: yesNotulae Scientia Biologicae, 2012
Pollen morphology of five Nymphaea (Nymphaeaceae) species, growing in Tripura, India were analysed using Scanning Electron Microscopy. Pollen grains of Nymphaea are dimorphic (ellipsoidal and spheroidal).

Assessment of Climate Change and Land Use Effects on Water Lily (Nymphaea L.) Habitat Suitability in South America

open access: yesDiversity, 2022
Many aquatic species have restricted dispersal capabilities, making them the most vulnerable organisms to climate change and land use change patterns. These factors deplete Nymphaea species’ suitable habitats, threatening their populations and survival ...

Catalysts for change: Museum gardens in a planetary emergency

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 401-410, March 2026.
Natural history museums are often seen as places with indoor galleries full of dry‐dusty specimens, usually of animals. But if they have gardens associated with them, museums can use living plants to create narratives that link outside spaces to inside galleries, bringing to life the challenges facing biodiversity.

A Temporally Consistent Spatial Gradient in Methane Ebullition From a Eutrophic Lake

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Gas bubble emission (ebullition) from lake sediment is a prominent source of the greenhouse gas methane (CH4) to the atmosphere, but the stochastic nature of bubble release and thus high variability in space and time makes the estimation of lake CH4 ebullition challenging.

Genome size and phenotypic variation of Nymphaea (Nymphaeaceae) species from Eastern Europe and temperate Asia

open access: yesActa Societatis Botanicorum Poloniae, 2015
Despite long-term research, the aquatic genus Nymphaea still possesses major taxonomic challenges. High phenotypic plasticity and possible interspecific hybridization often make it impossible to identify individual specimens.

The ecology of attraction: Fruit traits and frugivore diversity in neotropical Piper

open access: yesFunctional Ecology, Volume 40, Issue 3, Page 611-623, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits can benefit plant reproduction by enhancing seed dispersal by mutualistic frugivores (e.g. seed dispersal syndromes), but identifying the role of specific fruit traits in mediating frugivory is challenging because these traits can serve multiple functions ...

Heat Stress Modulates WDR5‐Mediated H3K4me3 Modification to Induce Melanogenesis via Activating CX3CL1/CX3CR1 Axis

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
This study elucidates the mechanism by which heat stress regulates skin pigmentation: heat stress upregulates CX3CL1 through the MYC‐WDR5‐H3K4me3 axis, thereby activating the CX3CL1/CX3CR1‐JNK signaling pathway and ultimately promoting melanogenesis. These findings provide novel potential therapeutic targets for pigmentary skin disorders.
