Abstract The comparative physiological ecology of two freshwater and one marine isolate of Bostrychia moritziana (Sonder ex Kutzing) J. Agardh from Venezuela and one marine isolate from Australia was investigated. Growth pattern and the concentrations of the isomeric hexitols d-dulcitol and d-sorbitol were examined in relation to a range of salinities ...

Freshwater and Marine Ecology is an introduction to the field of aquatic ecology, integrating the conceptually and methodologically widely overlapping fields of limnology and biological oceanography. It is structured like most textbooks of general ecology, leading from more elemental entities (individuals having to cope with their environment) to ...

Innate Immunity, Environmental Drivers, and Disease Ecology of Marine and Freshwater Invertebrates
Annual Review of Ecology, Evolution, and Systematics, 2006Despite progress in the past decade, researchers struggle to evaluate the hypothesis that environmental conditions compromise immunity and facilitate new disease outbreaks. In this chapter, we review known immunological mechanisms for selected phyla and find that there are critical response pathways common to all invertebrates.

Ecological speciation in marinev.freshwater fishes
Journal of Fish Biology, 2009Absolute barriers to dispersal are not common in marine systems, and the prevalence of planktonic larvae in marine taxa provides potential for gene flow across large geographic distances. These observations raise the fundamental question in marine evolutionary biology as to whether geographic and oceanographic barriers alone can account for the high ...

Environmental Monitoring and Assessment, 2008
In this study, we measured the mercury concentration in 27 different fish species with high commercial value. Samples were taken from a region characterized by the diversity of aquatic environments. Mercury concentration in marine fish species varied from 30.4 to 216 ng g(-1), while in estuarine species, it varied from 12.4 to 60.3 ng g(-1).

Ecology Letters, 2012
AbstractAdaptive radiations are typically triggered when a lineage encounters a significant range of open niche space (ecological opportunity), stemming from colonisation of new areas, extinction of competitors or key innovations. The most well‐known of these is the colonisation of new areas, through either dispersal into new regions or the invasion of

Fatty acids (FA) are a major source of nutrients and energy in aquatic food webs, as well as serving as the main components of all cell membranes. Increasing anthropogenic impacts (e.g., climate change) are predicted to selectively alter the production of these critical compounds, with potential cascading effects reaching higher trophic level ...

Abstract The highly pneumatic skeleton of the extinct flying pterosaurs suggests that they would float high up on open water, but in a posture rather different to that of birds. However, the exact posture of the body and head remains unknown and would be critical for an ocean going pterosaur forced onto the waters' surface or animals that alighted to
