Tolypella prolifera Leonh. in Indiana [PDF]

, 1950
Although members of the genus Tolypella have been found in Illinois and Ohio, apparently none have been reported previously from Indiana. On September 10, 1947, at Pokagon State Park, Steuben county, Indiana, in one of the display ponds, Tolypella ...

New Characeae (Charophyceae, Charales) report in eastern Sicily (Italy) [PDF]

Italian Botanist
Nowadays species belonging to the green algal family Characeae are highly endangered. For this reason, many of them are protected by European directives and included in Red Lists.

On the earliest occurrence of Tolypella section Tolypella in the fossil record and the age of major clades in extant Characeae [PDF]

, 2017
The genus Tolypella is considered the basal-most characean genus according to modern molecular phylogenies. Its fossil record, however, provides contradictory evidence since fossil Tolypella section Tolypella has its first fossil occurrence in the Late ...

Specialization among amphipods: the invasive Gammarus tigrinus has narrower niche space compared to native gammarids

Ecosphere, Volume 7, Issue 6, June 2016., 2016
Abstract Human‐mediated invasions of nonindigenous species are modifying global biodiversity. Despite significant interest in the topic, niche separation and specialization of invasive and closely related native sympatric species are not well understood. It is expected that combined use of various methods may reveal different aspects of niche space and

Carbon stable isotope composition of charophyte organic matter in a small and shallow Spanish water body as a baseline for future trophic studies

Journal of Limnology, 2015
Quantitative descriptions of foodweb structure based on isotope niche space require knowledge of producers’ isotopic signatures. In freshwater ecosystems charophytes are one of the main components of submerged vegetation and the feeding base for many ...

Go hard or go home: Major removal of woody vegetation and sediment greatly enhances wetland plant and water beetle diversity recovery in a farmland pond landscape

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
We investigated short‐term (1–3 years) pond biodiversity responses to restoration at a variety of management intensities. Ponds undergoing the most intense intervention (major woody vegetation and sediment removal) showed the strongest biodiversity uplift. This is likely in part due to a seedbank response and highlights the value of intense restoration

High levels of seed dispersal by a declining wintering population of migratory geese

Freshwater Biology, Volume 69, Issue 12, Page 1857-1870, December 2024.
Abstract Ducks are known to be important seed dispersers, but the role of geese in plant dispersal is less clear. Wintering populations of migratory geese are undergoing rapid changes in distribution and habitat use in response to climate change and changes in land use, and the implications for seed dispersal have not previously been studied.

Recreational land use contributes to the loss of marine biodiversity

People and Nature, Volume 6, Issue 5, Page 1758-1773, October 2024.
Abstract Coastal areas are at the centre of human–nature relationship, shaped by recreation, tourism and aesthetic values. However, socioeconomic drivers of biodiversity change in coastal areas have received less attention. Soft sediment seafloors support diverse species communities and contribute to ecosystem functionality.

Interactions between stoneworts (Charales) and waterbirds

Biological Reviews, Volume 99, Issue 2, Page 390-408, April 2024.
ABSTRACT Stoneworts (Charales) are green algae that represent an important food resource for many waterbird species in Europe and elsewhere. Browsing avian herbivores (e.g. swan, goose, duck and coot species) consume Charales plant vegetative parts, by head‐dipping, up‐ending or diving.
