Two populations of Brachythemis impartita (Karsch, 1890) are here reported in peninsular Italy. The species was found for the first time in 2015 in Calabria in the area of the Angitola artificial lake (Maierato and Monterosso Calabro municipalities) not far from the Tyrrhenian coast. In 2016 the species was also observed in southern Apulia, along the banks of two artificial lagoons in the municipality of Ugento. Information are provided that confirm the habitat preferences of the species and a northward expansion.

Dehydryn genes are involved in plant response to environmental stress and may be useful to examine functional diversity in relation to adaptive variation. Recently, a dehydrin gene (DHN3) was isolated in Quercus petraea and showed little differentiation between populations of the same species in an altitudinal transect. In the present study, inter- and intraspecific differentiation patterns in closely related and interfertile oaks were investigated for the first time at the DHN3 locus. A four-oak-species stand (Quercus frainetto Ten., Q. petraea (Matt.) Liebl., Q. pubescens Willd., Q. robur L.) and two populations for each of five white oak species (Q. frainetto Ten., Q. petraea (Matt.) Liebl., Q. pubescens Willd., Q. robur L. and Q. pedunculiflora K. Koch) were analyzed. Three alleles shared by all five oak species were observed. However, only two alleles were present in each population, but with different frequencies according to the species. At population level, all interspecific pairs of populations showed significant differentiation, except for pure Q. robur and Q. pedunculiflora populations. In contrast, no significant differentiation (p > 0.05) was found among conspecific populations. The DHN3 locus proved to be very useful to differentiate Q. frainetto and Q. pubescens from Q. pedunculiflora (FST = 0.914 and 0.660, respectively) and Q. robur (FST = 0.858 and 0.633, respectively). As expected, the lowest level of differentiation was detected between the most closely related species, Q. robur and Q. pedunculiflora (FST = 0.020). Our results suggest that DHN3 can be an important genetic marker for differentiating among European white oak species.

The caucasica species group in the subgenus Lunatipula is redefined and now consists of five species native to the Caucasus. Tipula (L.) eleniyasp. nov. is described as new to science, and variations in the male terminalia in two populations are noted. Two subspecies (quadridentataquadridentata and quadridentatapaupera) are elevated to species rank. Detailed photo’s complement the descriptions of all five species (caucasica, eleniya, paupera, quadridentata, talyshensis), and data on ecology and distribution patterns are included as well as identification keys to males and females. Tipula caucasica is recorded from the West Caucasus and Tipula quadridentata is recorded from Dagestan (Russia) for the first time. Parallel evolution is traced in the male terminalia of the new species and in several non caucasica species group of Palaearctic Lunatipula.

Comet 67P

The response of the mutual impedance probe RPC-MIP on board Rosetta orbiter electrostatically modeled considering an unmagnetized and collisionless plasma with two Maxwellian electron populations. A vacuum sheath surrounding the probe was considered in our model in order to take the ion sheath into account that is located around the probe, which is immersed in the cometary plasma. For the first time, the simulated results are consistent with the data collected around comet 67P/Churyumov-Gerasimenko (67P), but strong discrepancies were identified with the previous simulations that neglected the plasma sheath around the probe. We studied the influence of the sheath thickness and of the electron populations. This work helps to better understand the initially unexpected responses of the mutual impedance probe that were acquired during the Rosetta mission. It suggests that two electron populations exist in the cometary plasma of 67P.

All larval instars of the tiger beetle species Cosmodela aurulenta aurulenta (Fabricius, 1801) which is the type species of the genus Cosmodela Rivalier, 1961 are described and illustrated here for the first time, based on material from Bali Island (Indonesia). A brief review of habitat preferences and ecology for adults and larvae of Cosmodela aurulenta are provided. Differences between C. aurulenta and C. batesi (Fleutiaux, 1893) and allied Palaearctic genera of the subtribe Cicindelina are discussed. The preliminary key of known larvae of relevant genera and subgenera of the Oriental Region is given.

Microtus Townsendii

Two populations of Microtus pennsylvanicus were trapped simultaneously with Longworth live traps and pitfall traps over a 3- and a 4-year period. The number of voles enumerated by live traps was usually between 2 and 4 times that enumerated by pitfalls. Of the 3671 new voles caught, 53.7% were first caught in live traps. Pitfalls captured more of the juveniles first (56%) and live traps captured more of the adults first (76%). Animals entering live traps for the first time were about 4 g heavier than those entering pitfalls for the first time. The time lag between entry first into pitfalls and then to live traps was 4–6 weeks; the time lag between entry first in live traps and then to pitfalls was 2–7 weeks. Approximately 18% of all voles never entered live traps. Live traps captured about 83% (N = 747) of all dispersers whereas pitfalls captured about 46%. We conclude that live traps were much more effective than pitfalls in capturing this species. These results are very different from those reported from studies on Microtus townsendii.

A northward expansion of the range of Willow Flycatchers has resulted in regions of secondary contact with Alder Flycatchers. The foraging ecology of both species overlaps extensively for both mutually allopatric and sympatric populations. Willow Flycatchers choose a more xeric upland habitat in southwestern Ontario than they do farther north at a site of secondary contact near Stouffville, Ontario. Alder Flycatchers at both Stouffville and Ottawa show similar habitat preferences. Habitat types chosen by both species at Stouffville overlapped considerably. Despite the extensive niche overlap at Stouffville, no evidence of competition between the species was observed.
