Traceability Issues in the Trade of Marine Ornamental Species

Reviews in Fisheries Science, 2013
In the last decade, the trade of marine ornamental species has experienced a significant expansion worldwide; however, this industry still relies on a large number of unsustainable practices (e.g., cyanide fishing, overexploitation of target species) and needs to shift its operations urgently to avoid collapsing.

VIRUSES INFECTING ORNAMENTAL ALLIUM SPECIES IN POLAND

Journal of Plant Pathology, 2017
The aim of the present work was to identify allexiviruses (GarMbFV, GarV-A, GarVB, GarV-C, GarV-D, GarV-E, GarV-X and ShVX), carlaviruses (GarCLV, SLV) and potyviruses (LYSV and OYDV) in ornamental plants from the genus Allium. Two groups of tested plants were used.

Tropical species of Psathyrella with ornamented spores

Mycological Research, 1992
Two palaeotropical species of Psathyrella with ‘ornamented’ basidiospores are described and illustrated with line drawings and SEM micrographs. The definition of the genus Psathyrella is modified to accommodate these species. Psathyrella nigeriensis is proposed as a new species.

Reproductive skew and selection on female ornamentation in social species

Nature, 2009
Male animals are typically more elaborately ornamented than females. Classic sexual selection theory notes that because sperm are cheaper to produce than eggs, and because males generally compete more intensely for reproductive opportunities and invest less in parental care than females, males can obtain greater fitness benefits from mating multiply ...

Ecotoxicological responses of three ornamental herb species to cadmium

Environmental Toxicology and Chemistry, 2013
Abstract   Cadmium is one of the most toxic elements. The ideal vegetal cover should be ensured by the selection of appropriate plant species for successful phytoremediation. In the present study, the ecotoxicological effects of Cd on the following 3 ornamental herbs were investigated: Italian ...

Airborne pollen of ornamental tree species in the NW of Spain

Environmental Monitoring and Assessment, 2010
This study analyzed airborne pollen counts for the tree taxa most widely used for ornamental purposes in the northwestern Iberian Peninsula (Platanus, Cupressaceae, Olea, Myrtaceae, Cedrus, and Casuarina) at four sites (Vigo, Ourense, Santiago, and Lugo), using aerobiological data recorded over a long period (1993-2007).

Our hardy Hibiscus species as ornamentals

Economic Botany, 1970
As a common plant name, "Hibiscus" is more often applied to the showy tropical sorts, especially Hibiscus rosa-sinensis L., than to other species of the genus. There is, however, another equally showy group, the hardy herbaceous mallows, native mostly to the Eastern United States. This group includes Hibiscus moscheutos L., H.

ORNAMENTAL USE OF WILD SPECIES OF GENUS GLADIOLUS

Acta Horticulturae, 2003
Two Mediterranean species of genus Gladiolus were studied in order to diversify the range of ornamental plants on offer: G. illyricus for use as a rockery plant and G. italicum preferably for use as a cut flower, although it could be used in gardening. Both species can be sexually or asexually propagated, although seed production is higher than cormels

Some Australian Ornamental Woody Species

1989
Hutchinson et al. (1985) listed over 50 Australian species which have been successfully tissue cultured but only a few have been produced commercially, and of these Eucalyptus spp. and Grevillea cultivars are the only woody species. Initial work has been done on the in vitro propagation of a number of species but little in-depth work has been reported.
