Invasive species over-stabilise the vegetation of a mobile dunefield, Manawatū, New Zealand, disrupting natural succession [PDF]

Vegetation Classification and Survey (VCS), 2023
Aims: Mobile, coastal dunefields around the world are under threat from invasive plants, which may out-compete native plant species. These aliens may also accelerate stabilisation of the dunes, to the complete exclusion of early successional native flora.

Invasion of the North American sand dropseed (Sporobolus cryptandrus) – A new pest in Eurasian sand areas?

Global Ecology and Conservation, 2021
For the effective control of an invasive species, gathering as much information as possible on its ecology, establishment and persistence in the affected communities is of utmost importance. We aimed to review the current distribution and characteristics

Fifteen years of habitat, floristic and vegetation change on a pioneer sand-dune and slack system at Ainsdale, north Merseyside, UK

British & Irish Botany, 2021
Changes in habitat, floristics and vegetation between 2005 and 2019 were studied on 2.9 ha of sandy foreshore near Ainsdale-on-Sea, north Merseyside. Named the ‘New Green Beach’, the site initially supported saltmarsh vegetation but, within five years, a 30-35 m-wide embryo dune ridge had formed, eventually 3.5 m high, backed by a 300 x 30 m seasonally

Contribuição ao conhecimento da distribuição espacial de Paepalanthus polyanthus (Bong.) Kunth (Eriocaulaceae) em áreas de baixada úmida de dunas Contribution to the knowledge of the distribution of Paepalanthus polyanthus (Bong.) Kunth (Eriocaulaceae) in areas of dunes

Acta Botânica Brasílica, 1996
A distribuição espacial de Paepalanthus polyanthus foi avaliada em função da variação topográfica e da cobertura vegetal associada, em um trecho de baixada úmida de dunas na Praia da Joaquina, Florianópolis, SC.

Population ecology of Paepalanthus polyanthus: predispersal hazards and seed production Ecologia populacional de Paepalanthus polyanthus: riscos de pré-dispersão e produção de sementes

Acta Botânica Brasílica, 2000
This study aimed at evaluating seed production and predispersal hazards in a sand dune population of P. polyanthus (Eriocaulaceae) in Southern Brazil. Bad development of flowering capitula was caused by the wind and by interference among umbels.

Population ecology of Paepalanthus polyanthus (Bong.) Kunth: temporal variation in the pattern of spatial distribution [PDF]

Biotemas, 2004
The temporal variation in density and pattern of spatial distribution of Paepalanthus polyanthus (BONG.) Kunth (Eriocaulaceae) were evaluated at a determinate sand dune.

Five-year carry-over effects in dune slack vegetation response to hydrology

Ecological Indicators
Dune slacks are biodiverse seasonal wetlands within sand dune systems, strongly influenced by the dynamics of the local groundwater regime. Future climate predictions indicate strong adverse impact on the hydrology and therefore ecology of these wetland ...

Effects of Bothriochloa ischaemum on the Diversity of Pannonian Sandy Grasslands

Land
Changes in land use and agricultural practices have altered the resilience of plant communities and can lead to the emergence of invasive species. One of these is the perennial grass species Bothriochloa ischaemum (L.) Kleng., whose diversity-reducing ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Palaeowinds and depositional conditions from Holocene loess in Sweden and Finland

Boreas, EarlyView.
The nature of deglacial and Holocene wind regimes in Fennoscandia is debated, as is the degree to which wind‐blown loess deposits exist in the region. Loess deposits in Fennoscandia are often relatively thin, discontinuous and less well‐sorted than typical loess, and questions remain over the degree of their post‐depositional reworking and the impact ...
