Eleocharis Palustris

Eleocharis palustris (Linnaeus 1753: 70) Roemer & Schultes (1817: 151) belongs to the Eleocharis Brown (1810: 224) subser. Eleocharis (Bureš et al. 2004). In Europe (see Walters 1980, Jiménez-Mejías & Luceño 2011, Pignatti 2017), two subspecies are widely accepted and reported: E. palustris subsp. palustris and E. palustris subsp waltersii Bureš & Danihelka (2008: 227) [≡ E. palustris subsp. vulgaris Walters (1949: 194), nom. illeg.].

Eleocharis Palustris

The purpose of this study was to identify significant species relationships and underlying ecological gradients characteristic of the Huntingdon Marsh, Quebec. In 1970, one hundred and seven 1-m2 samples of plant biomass were obtained from the marsh in conjunction with environmental measurements. These data were later analyzed using principal-components analysis.The marsh complex divided unambiguously into emergent aquatic and sedge meadow communities on the basis of distinct environmental and compositional differences. Equisetum fluviatile, Scirpus fluviatilis, Eleocharis palustris, and Scirpus validus were major species in the emergent aquatic community. Respectively, these species dominated 29, 25, 16, and 14% of 51 quadrats on a dry weight basis. Water depth accounted for almost one-third of the species variation in this community. Interaction between submerged and floating forms and competitive exclusion between dominant species explained much of the remaining species variance.On a dry weight basis, Carex aquatilis, C. lacustris, Calamagrostis canadensis, and Typha angustifolia dominated 36, 16, 16, and 11% of the 56 quadrats on the sedge meadow. As a group, Carex spp. dominated 63% of the quadrats. Disturbance related to chance perturbations, water depth, and the incidence of fire accounted for much of the variation in this community.The organization of emergent and sedge meadow communities was discussed in relation to continuum and community concepts with particular reference to relative changes in discontinuity of species relationships across the environmental gradient.

Continuous Range

Pilularia globulifera is a subatlantic European fern threatened with extinction. In Poland, it reaches the eastern border of its continuous range. Up to the end of the 20th century, it was observed here in 21 stands; only 2 of them existed by the second half of the century, so the species was categorized as critically endangered. Five new locations have been found in western and northwestern Poland during the last 10 years. Abundant and permanent populations grow in 3 locations, while 2 stands were ephemeral. All the current stands are situated in anthropogenic habitats with spontaneous vegetation, in oligotrophic to eutrophic waters. One of the new localities is about 280 km distant from the eastern range of the limit known previously. Pilularia forms its own plant community Pilularietum globuliferae, enters plots of Ranunculo-Juncetum bulbosi and occurs in mesotrophic to eutrophic rushes of Eleocharis palustris, Phragmites australis, Typha angustifolia and Equisetum fluviatile. Specimens are vigorous and regularly produce sporocarps.

Descriptive Method

The growth of weeds in the rice fields can reduce production. Weed is a disrupting plant that grows and spreads rapidly so it becomes a nutritional competitor for cultivated plants. This study aims to identify rice weeds in the fields of Rimau District, Banyuasin, South Sumatra. The research method used was descriptive method with purposive sampling on wetland rice fields of the Ciherang variety. Sampling was carried out in a critical period (3-6 weeks after planting) in rice fields. The results of weed identification obtained 6 families consisting of 15 species, namely Ageratum conyzoides L., Crassocephalum crepidioides, Cleome rutidisprema DC., Cyperusroduntus L. Cyperus compressus, Eleocharis palustris L., Frimbristylis miliacea L. Vahl, Phylanthus naruri L., Eurphobia hirta, Cynodon dactylon (L.) Press., Digitaria ciliaris (Retz.) Koel., Echinochola colona (L.) Link., Eleusinindica (L.) Gaertn., Paspalum scrobiculatum L., Ludwigia octovalvis (Jacq.) Raven. The Poaceae family is most commonly found as a rice weed in Rimau District, South Sumatra.

Eleocharis Palustris

Food selection by Canada geese (Branta canadensis), staging in the autumn on the Nisutlin River delta in the south central Yukon Territory, was investigated between August and October of 1981, 1982, and 1983. Three distinct plant associations were used by the foraging geese: an aquatic association in which rhizomes of Potamogeton richardsonii, the dominant species, were eaten; a terrestrial and more vegetatively complex association in which Equisetum palustre was the main plant taken; and an association of almost pure stands of Equisetum fluviatile in wet depressions behind old river levees. Availability of these feeding zones depended on water levels on the delta. When water levels were low (October 1982), all feeding zones were available, yet the geese fed almost entirely in the Potamogeton zone, indicating a preference for that zone. At intermediate water levels, Potamogeton richardsonii was no longer available and the geese grazed on the complex vegetative zone, taking Equisetum palustre, Ranunculus reptans, and Eleocharis palustris in the ratio of their relative availability (85:10:5). Only when water levels were high did the geese graze exclusively in the Equisetum fluviatile zone, the least preferred.
