New perspectives for estimating body condition from mass/length data: the scaled mass index as an alternative method
Body condition is assumed to influence an animal’s health and fitness. Various non-destructive methods based on body mass and a measure of body length have been used as condition indices (CIs), but
MASS/LENGTH RESIDUALS: MEASURES OF BODY CONDITION OR GENERATORS OF SPURIOUS RESULTS?
In studies of animal ecology, it is fashionable to use the residuals from an ordinary least squares (OLS) linear regression of body mass against a linear measure of size (the body size indicator,
The paradigm of body condition: a critical reappraisal of current methods based on mass and length
TLDR
All six conventional CI methods are presented and it is shown that, unlike the Scaled mass index, all six conventional methods fail to do this, and as a result they consistently lead to significant differences in CIs between age classes and sex that are a mere consequence of changes in body size.
Dispersal of aquatic organisms by waterbirds: a review of past research and priorities for future studies
TLDR
A literature review indicates that bird-mediated passive transport of propagules of aquatic invertebrates and plants is a frequent process in the field, at least at a local scale, and both endozoochory (internal transport) and ectozooChory (external transport) are important processes.
Phylogeography and local endemism of the native Mediterranean brine shrimp Artemia salina (Branchiopoda: Anostraca)
TLDR
The results show extensive regional endemism and indicate an early Pleistocene expansion of A. salina in the Mediterranean Basin and large genetic divergences between Mediterranean and South African A.salina suggest that the latter deserves species status.
Recent advances in the study of long‐distance dispersal of aquatic invertebrates via birds
TLDR
There is a particular need for more quantitative studies of LDD by birds that will enable modellers to assess its role in maintaining invertebrate biodiversity among increasingly fragmented wetlands and in the face of climate change, as well as in the spread of invasive species.
Dispersal of invasive and native brine shrimps Artemia (Anostraca) via waterbirds
TLDR
It is found that large numbers of viable eggs of A. franciscana and native Artemia parthenogenetica were dispersed by Redshank Tringa totanus, Blacktailed Godwit Limosa limosa, and other shorebirds migrating through the Iberian Peninsula, the most extensive field demonstration to date that invertebrates can disperse readily via gut passage through birds.
Invertebrate Eggs Can Fly: Evidence of Waterfowl‐Mediated Gene Flow in Aquatic Invertebrates
TLDR
Differences in the capacity to exploit bird‐mediated transport are likely to have important consequences for the ecology of aquatic communities and the spread of invasive species.
