Riparian vegetation diversity in boreal headwaters: Comparing streams, modified waterways, and ditches

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Decades of forest management in the boreal biome have involved digging drainage ditches and modifying streams to increase timber production, altering terrestrial ecosystems and expanding stream networks. Modified waterways and drainage ditches represent widespread novel aquatic and riparian ecosystems, with little known about their ...

The peculiarity of hydrophytes and helophytes diaspors distribution in dependent of synanthropic problem [PDF]

open access: yes, 2006
The article gives principal means of generative diaspores of hydrophytes and helophytes distribution: hydrochory, anemochory, epizoochory, etc. It was determined, that for most species of ponds and bogs flora inherent several means of distribution ...

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1270-1285, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 3, Page 520-535, May 2026.
A densely sampled phylogeny of Carex section Lupulinae (107 specimens) is presented, along with a new cryptic species from the southern United States. This species is locally abundant and genetically and morphologically distinct from other Lupulinae. An identification key is provided and phenological and ecological patterns are discussed.

Dispersal Syndromes of fossil Seeds from the Lower Permian of Paraná Basin, Rio Grande do Sul, Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2012
The morphological analysis of seeds has been an important subject in modern ecological studies, once it provides evidence about the biology and adaptations of the parent plant.

Plant Community Composition along the Historic Verde River Irrigation System: Does Hydrochory Play a Role? [PDF]

open access: yes, 2010
: As an industrial society, humans have increasingly separated agricultural processes from natural ecosystems. Many areas of the Southwestern US, however, maintain traditional practices that link agricultural systems to the natural environment.

Seventy-five mosses and liverworts found frozen with the late Neolithic Tyrolean Iceman: Origins, taphonomy and the Iceman's last journey.

open access: yesPLoS ONE, 2019
The Iceman site is unique in the bryology of the Quaternary. Only 21 bryophytes (mosses and liverworts) grow now in the immediate vicinity of the 5,300 year old Iceman discovery site at 3,210m above sea level in the Ötztal Alps, Italy.

Extensive hydrochory uncouples spatiotemporal patterns of seedfall and seedling recruitment in a ‘bird‐dispersed’ riparian tree [PDF]

open access: yesJournal of Ecology, 2004
Summary Initial recruitment is by far the most variable and least predictable phase of the plant life cycle. Its dynamics remain little known, particularly in complex seed dispersal systems and over multiple reproductive cycles. Seeds of the tree Frangula alnus are usually dispersed by frugivorous birds.
