Bottleneck effects and the depression of genetic variability in hatchery stocks of Penaeus japonicus (Crustacea, Decapoda)
TL;DR: Genetic analysis of the founder stock and five subsequent hatchery generations revealed a constant reduction in levels of allozyme polymorphism, which pointed out the importance of a careful check of the number of spawners actually contributing to each reproductive cycle.

Pleistocene evolutionary history of the Clouded Apollo (Parnassius mnemosyne): genetic signatures of climate cycles and a ‘time-dependent’ mitochondrial substitution rate
TL;DR: It is argued that the calibrated ‘time‐dependent’ rate (0.096 substitutions/million years), offers the most convincing time frame for the evolutionary events inferred from sequence data.
Asymmetrical responses of forest and ''beyond edge'' arthropod communities across a forest-grassland ecotone
Federica Lacasella,Federica Lacasella,Claudio Gratton,Stefano De Felici,Marco Isaia,Marzio Zapparoli,Silvio Marta,Valerio Sbordoni +7 more
TL;DR: In this paper, the authors investigated the extent to which a habitat edge influenced communities of arthropods associated with either the forest or grassland, and how far from the edge this effect penetrated into each habitat.
Molecular biogeography: Using the Corsica-Sardinia microplate disjunction to calibrate mitochondrial rDNA evolutionary rates in mountain newts (Euproctus)
TL;DR: These are the first mt‐rDNA sequence data for salamanders and were used to reconstruct phylogenetic trees, investigate evolutionary rates for these genes, calibrate them with absolute time since divergence, and compare rates with published ones.

Phylogeography of Parnassius apollo: hints on taxonomy and conservation of a vulnerable glacial butterfly invader
TL;DR: It is proposed that P. apollo is best viewed as an atypical glacial invader in southern and western Europe, the isolated, montane populations of which, threatened by climate warming, retain a large fraction of the species evolutionary heritage.
