Biological Flora of Britain and Ireland: Silene uniflora‡

Journal of Ecology, Volume 112, Issue 9, Page 2135-2157, September 2024.
Sea Campion (Silene uniflora) flowers throughout the summer on cliffs, dunes and shingle, mainly around the Atlantic and Baltic coasts of Europe. Plants may have hermaphrodite flowers, female‐only flowers or both. Long‐tongued Hymenoptera and night‐flying moths are important pollinators, and they commonly also transmit a castrating fungal disease ...

Indexes of pasturable ecology of Equus ferus przewalskii (Equidae) in steppes of the Western Manych Valley (south-east of the Rostov Region, Russia)

Nature Conservation Research: Заповедная наука, 2019
In 2015–2016, we studied the species composition, above-ground phytomass and feeding habits of semi-free Przewalski's horses (Equus ferus przewalskii) in a natural pasture of the steppe valley of the Western Manych. The above-ground mass of plants on the

Beyond salinity: Plants show divergent responses to soil ion composition

Global Ecology and Biogeography, Volume 33, Issue 5, May 2024.
Abstract Aim In salt‐affected environments, salinity shapes ecosystem functions and species composition. Apart from salinity, however, we know little about how soil chemical factors affect plant species. We hypothesized that specific ions, most of which contribute to salinity, co‐determine plant niche differentiation. We asked if the importance of ions

Host specialization of different populations of ergot fungus (Claviceps purpurea)

Czech Journal of Genetics and Plant Breeding, 2002
In our previous study of Claviceps purpurea three populations were found: G1 on open localities, G2 from shady or wet habitats and G3 on Spartina stands of coastal salt marshes. The latter two are also chemoraces.

The dynamics of Cirsium arvense and Elytrigia repens in long-termed organic crop rotation experiments [PDF]

, 2014
Cirsium arvense and Elytrigia repens are perennial weeds prevalent in organic cropping systems in Scandinavia. This study analysed the population dynamics of both species in long-termed crop rotation experiments conducted at three sites (coarse sand ...

Transfer seeds, hay, or soil blocks? The importance of the completeness of biological inputs to address dispersal and establishment limitations during the restoration of plant assemblages in floodplain grasslands

Restoration Ecology, Volume 32, Issue 3, March 2024.
This study investigated different techniques of grassland restoration to overcome dispersal or establishment limitation, which are key processes influencing early‐successional plant community assembly. A fully randomized in situ experiment was set up in a former arable land in a floodplain along the Garonne river (south‐western France) to test for the ...

Improvement of an elutriation method for estimation of weed seedbank in the soil

Plant, Soil and Environment, 2002
A model experiment was conducted to compare hand extraction (elutriation) under running water and elutriation using the device Analysette 3, the two methods for estimation of weed seedbank in the soil.

Robots and shocks: emerging non‐herbicide weed control options for vegetable and arable cropping

New Zealand Journal of Agricultural Research, Volume 67, Issue 1, Page 81-103, February 2024.
ABSTRACT For decades, herbicides have provided easy‐to‐use, cost‐effective weed management, but alternatives are desired. Consumer preference for chemical‐free food, awareness of environmental impacts, regulation increasingly restricting agrichemical use, and increasing prevalence of herbicide resistance are forcing changes to weed management ...
