Abstract
Guard-sneaker tactics are widespread among fish, where territorial males defend a nest and provide parental care while sneakers try to steal fertilizations. Territorials and sneakers adopt diverse pre- and post-mating strategies, adjusting their ejaculate investment and/or behavioural responses to the presence of competitors. The relative distance of competitors from the spawning female plays a major role in influencing male mating strategies and the resulting paternity share. However, territorial male quality and sneaking intensity do not fully account for the variability in the relative siring success occurring among species. An often neglected factor potentially affecting sneakers proximity to females is the nest structure. We conducted a field experiment using the black goby, whose nests show two openings of different size. We found that territorial males defend more and sneaking pressure is higher at the front, larger access of the nest than at the back, smaller one. Moreover, microsatellite paternity analysis shows that territorials sire more offspring at the back of their nest. Such a predictable spatial distribution of the paternity share suggests that nest structure might work as an indirect cue of male relative siring success, potentially influencing the territorial male investment in parental care and/or the female egg deposition strategy.

Abstract
Understanding the genetic quality of the gerbil, Meriones meridianus,
plays an important role in the study of medical biology. However, no effective system has
been established for evaluating a population’s genetic diversity to date. In the present
study, we established a set of reasonable evaluative systems based on microsatellite
markers of the Mongolian gerbil by using the method of cross-amplification of species.
Following electrophoresis analysis, short tandem repeat (STR) scanning, and sequencing, 11
microsatellite loci were identified by matching the criteria characteristics and were used
to evaluate the genetic diversity of two stocks of Meriones meridianus: Meriones
meridianus jei Wang, 1964 (M. m. jei) and Meriones
meridianus cryptorhinus Blanford, 1875 (M. m. cryptorhinus)
from Xinjiang, China. The microsatellite loci screened were highly polymorphic and were
suitable for genetic quality control of Meriones meridianus. In addition,
the quality of the non-bred M. m. jei and M. m.
cryptorhinus strains in our study is sufficient for them to be promising stocks
in the future for the farmed animal industry.

The invasive bighead goby Ponticola kessleri displays large-scale genetic similarities and small-scale genetic differentiation in relation to shipping patterns. Mol Ecol 2016; 25:1925-43.

Abstract
Colonization events, range expansions and species invasions leave genetic signatures in the genomes of invasive organisms and produce intricate special patterns. Predictions have been made as to how those patterns arise, but only very rarely, genetic processes can be monitored in real time during range expansions. In an attempt to change that, we track a very recently established invasive population of a fish species, the bighead goby Ponticola kessleri, with high temporal and spatial resolution through 2 years to identify patterns over time. We then compare Swiss and German samples of bighead goby along the river Rhine using microsatellites, mitochondrial D-loop sequences and geometric morphometrics to investigate geographic patterns. We detect weak temporal and strong geographic patterns in the data, which are inconsistent with isolation by distance and indicate long range transport. In search of an explanation for our observations, we analyse the vector properties and travel patterns of commercial vessels on the river Rhine. We present evidence that freshwater cargo ships and tankers are plausible vectors for larvae of invasive goby species. We also present indications that cargo ships and tankers act as differential vectors for this species. In summary, we present genetic data at unique temporal resolution from a vertebrate invasion front and substantiate the paramount role of commercial shipping in freshwater fish translocations.
