Throughout most of the distributional range, the fat dormouse, Glis glis, relies heavily upon European beech as a key species in its habitat. In Lithuania however, situated beyond the continuous range of the beech, pedunculate oak becomes the essential tree in habitats of G. glis. In Lithuania, the dormouse activity season lasts from mid-May to mid-October, young are born during the short period from late July to mid-August, and the mean litter size is 5.9 young. Population density is low (0.8-2.0 ind./ha after hibernation and 1.2-4.8 ind./ha in autumn), but relatively stable. The mean body weights of adults (98 g after hibernation and 128 g before hibernation) are among the lowest across the range. Lithuanian dormice differ from those living in beech-dominated habitats by their lower population density and lower body weight. Such differences may be due to acorns being less suitable food for G. glis in comparison to beech nuts. In terms of inter-annual abundance dynamics, the G. glis population is comparatively stable as years in which dormice fail to reproduce are infrequent in Lithuania.
The fatty acid composition is associated with obesity. Omega 3 polyunsaturated fatty acid (PUFA) could have a beneficial role in the prevention and treatment of many disorders, including cardiometabolic diseases. A cohort of 84 men and 131 women were examined in adolescence and after 8 years. Body weight (BW) and fat mass (FM) were measured. The composition of fatty acids (FAs) of serum phospholipids was assessed using gas chromatography. Statistics: PLS method. Aim: to determine the relationships between FAs in adolescence and FM (explanatory variable 1, EV1) and BW (explanatory variable 2, EV2) in adulthood. In the predictive models, a cluster of FAs in boys explained 47.2 % of EV1 and a cluster of 6 FAs in girls explained 32.3 % of EV1 measured in adulthood. FAs measured in adolescents explained 23.7 % of EV2 in early adults regardless of gender. A significant negative association was found between 18:1n-9c and EV1 in males and EV2 in both genders. We found a significant negative association between 18:2n-6 and 20:0 and both EV1 and EV2. In all analyses, we found a significant negative association of 20:1n-9 and 18:3n-3 with EV1-2 in both genders. A significant positive association was found in 20:3n-6 with EV1 and EV2 in males. 20:4n-6 was positively associated with EV1 in females and EV2 in both genders. A positive association between FM and very long chain n- 6 PUFAs was also observed. It is concluded that serum MUFAs and essential PUFAs in adolescence are associated with lower BW and FM in adulthood.
Five new species of Mulcticola Clay et Meinertzhagen, 1938 are described and illustrated from Brazil. These new species and their hosts are: Mulcticola sicki sp. n. from the sand-coloured nighthawk, Chordeiles rupestris rupestris (Spix), Mulcticola bacurau sp. n. from the common pauraque, Nyctidromus albicollis (Gmelin), Mulcticola tendeiroi sp. n. from the long-trained nightjar, Macropsalis forcipata (Nitzsch), Mulcticola piacentinii sp. n. from the short-tailed nighthawk, Lurocalis semitorquatus semitorquatus (Gmelin) (type-host) and L. s. nattereri (Temminck), and Mulcticola parvulus sp. n. from the little nightjar, Setopagis parvula (Gould). These species were compared primarily with Mulcticola nacunda Carriker, 1945 from the nacunda nighthawk, Chordeiles nacunda nacunda (Vieillot), which is one of the species of Mulcticola previously recorded in the Neotropical region. All the five new species described herein differ from their congeners by exclusive characters such as the shape of anterior dorsal head plate, metasternal plate, subvulvar plates in females and genitalia in males. We increased the number of species in Mulcticola to 18 in total, with seven of them now known from the Neotropics. We present the main morphological characters to distinguish Mulcticola from other species of the Philopteridae parasitising Caprimulgiformes and also compile a detailed catalogue for species included in this louse genus., Michel P.

Two new species of feather mites are described from nightjars (Caprimulgiformes: Caprimulgidae) of Brazil: Hartingiella neotropica sp. n. (Xolalgidae) described from Hydropsalis parvula (Gould) and Paragabucinia brasiliensis sp. n. (Gabuciniidae) from H. albicollis (Gmelin). The former differs from the type species by having, in males, the anterior projections on epimerites III towards setae 3b and the adanal shield bearing setae ps3 present; in both sexes, a pair of small sclerites situated posterior to setae se have flat suprategumental processes. Paragabucinia brasiliensis sp. n. differs from P. petitoti (Gaud et Mouchet, 1959) by the smaller size of the incisions in the internal margins of opisthosomal lobes of males. These mites are the first representatives of corresponding genera described from the Neotropical region. The genus Hartingiella Gaud, 1980 was previously known solely from its type species. Keys to males and females of the genus Paragabucinia Gaud et Atyeo, 1975 are presented. In addition, all previous records of feather mites associated with birds of the order Caprimulgiformes of the world are summarised.

The systematics of the genus Zabrus Clairville, 1806 is currently based on morphological characters that show a high degree of parallelism. The aim of this study is to find new characters in the female genitalia, which give a better understanding of the phylogeny of the genus and result in a new classification based on monophyletic taxa (subgenera and species groups). For this purpose slides of the whole female reproductive tract were studied under light microscopy and the gonocoxa IX under scanning microscopy. The study of species belonging to eight subgenera of Zabrus, and of twelve subgenera of its sister taxon Amara, shows that Zabrus is characterised by the lack of a spermatheca. This apomorphy is reported for the first time in carabids, and corroborates the monophyly of the genus in comparison to Amara. A villous canal that is intimately joined to the distal bursa copulatrix was found in both genera and in species of related tribes. This feature could be an apomorphy of the Harpalidae sensu Deuve (1988). However, only in Zabrus does the villous canal end in a long falciform head, which is probably another autapomorphy of the genus. It is postulated that the primitive bursa copulatrix of the genus was made up of a moderately inflated basal half and an elongated and simple distal half. This pattern is found in species of the subgenus Zabrus, which are widely distributed, and the subgenera Euryzabrus, Platyzabrus, and Epomidozabrus, which are endemic to the Iberian Peninsula. Extra lobules arising in the region where the two parts of the bursa meet, and cup-like infoldings of the distal bursa are possible apomorphic states that characterise the subgenera Pelor and Iberozabrus. Gonocoxite 2 does not have the strong and short spines found in species of related taxa. Differences in size and shape of both gonocoxites, distribution of setation and microtrichia, and presence of furrow "pegs" are characters of potential phylogenetic interest, which should be thoroughly investigated in other subgenera.
This article presents the partial research findings on financial instability as a risk factor for the recurrence of homelessness among families enrolled in a Housing First project in the City of Brno (Czech Republic). The project represents an evidence-based social innovation focused on ending families’ homelessness. The research was designed as a Randomised Controlled Trial study accompanied by a qualitative evaluation. The data were collected through questionnaires, individual interviews, and focus groups. In the results section we follow the logic of a financial stability model and conclude that research results on financial stability overall did not prove to be statistically significant on a short-term scale. In the discussion, we state that prolonged material poverty combined with the nature of the Czech housing benefit system and the experience of residential alienation could increase the risk of the recurrence of homelessness for families. A crisis financial fund was established in an effort to prevent this.
