The experiment was run in a controlled-temperature room (18 °C) with a 12 h light:12 h dark cycle. To create different levels of species richness, all seven species were assembled in mono-, di-, and tri-cultures (Figure 1A, Table 1). For logistical reasons, we reduced the total ...
and U. minor are the most representative species in permanent waterbodies, and Tamarix sp. and N. oleander may also occur. The most abundant macrophytes in permanent waters are Typha domingensis, Phragmites australis and Juncus sp. Along most rivers on the left side, shrubs are the natural ...
However, populations of this species on the Humber estuary in the United Kingdom appear transient and consequently, according to the criteria developed by *E-mail: a.j.lawrence@hull.ac.uk © Inter-Research 2001 · www.int-res.com Philips (1980), this species does not appear to be ideal...
increase in volume of the brood as hatching approaches. Seasonal changes in Stage I (early) egg size are marked in this species, with winter eggs as much as 60% greater in volume than summer eggs. Egg size is inversely related to the temperature during oocyte development. A simple model ...
The amphipod Gammarus duebeni harbours several species of vertically transmitted microsporidian parasites. G. Duebeni were collected from 3 localities in the UK. Animals from Budle Bay, Northumberland, were infected with Octosporea effeminans, and those from Millport, Isle of Cumbrae and Fenham Fla...
Viral diseases of crustaceans are increasingly recognised as challenges to shellfish farms and fisheries. Here we describe the first naturally-occurring virus reported in any clawed lobster species. Hypertrophied nuclei with emarginated chromatin, charac
However, eight of the pairs resided in the marine reserve which also indicating a high site fidelity. Further research to unveil the genetically significance of multiple paternity and what drives the females' choice is important for management of this high valued species. 展开 ...
of the amphipod hosts in which putative nudiviruses have been reported are non-native or invasive species present outside of their native ranges. Infection with this viral family may therefore have potential for transboundary transmission when their hosts are present in their invasive range7,10,11....
Some of them, particularly if limited to a small fraction of the population, may be rapidly eliminated due to embryo mortality, whereas neutral genetic changes can be perennialized, inducing changes in the relationships with other species in the community, such as fish, crabs, or bivalves (...
