The morphological characteristics of the femora of 377 fisher and 142 marten were studied to determine those characteristics which could be used to distinguish between species and between sexes. Measurements and illustrations were used to supplement the descriptions of these bones. The femora of marten and fisher are similar in structure but it is possible to distinguish between these bones using morphometric data. Distinction can also be made between femora of male and female marten using bone measurements. The robustness of these femora was also examined. The femora of female marten were more robust than those of male marten, while those of male and female fisher were similar in robustness.

Ornitophera sp. is one of the groups of butterflies endemic in Papua and West Papua provinces. The significant morphological differences between male and female butterflies (dimorphism) are in the shape, size and color of the wings. Morphological characteristics are important sources of information. Based on the results of specimen collections at the Papua Insect Collection Laboratory (KSP) Jayapura, there are several species from various locations in Papua. The variation in dimorphism is likely to occur in this species which gives rise to new sub-species. The purpose of this study was to record the dimorphism of the endemic Bird Wing of Papua which had been stored in the Papua Insect Collection Laboratory (KSP) Jayapura. The method used is a direct measurement of the morphology of bird wing butterfly specimens stored in the KSP Laboratory, Cenderawasih University. Morphometric data were analyzed using the SPSS 20 and Multi Variate Statistical Package (MVSP 3.1) programs. The results obtained were 7 Ornithoptera species stored in the KSP Jayapura Laboratory, namely O. chiamera, O. goliath, O. meridionalis, O. paradisea, O. priamus, O. thitonus and O. rothschildi. Based on observations there are striking differences in color, shape and size between male and female in the same species.   Key words: birdwing butterfly, Ornithoptera sp., KSP Jayapura, dimorphisme.

Abstract Parthenitae and cercariae of Plagiorchis. multiglandularis Semenov, 1927 are recorded in Lymnaea stagnalis (Linnaeus, 1758) for the fi rst time in Ukraine; their morphological characteristics are specifi ed. Diagnostic characters of P. multiglandularis parthenitae and cercariae found in Ukrainian Polissia are compared with those from other regions. To confi rm the validity of the species, a comparison of the morphometric data of this trematode larvae with the cercariae of Plagiorchis elegans (Rudolphi, 1802) Braun, 1902, found in molluscs L. stagnalis, L. ralustris and L. corvuses, was performed. It was determined that P. multiglandularis cercariae diff er from those of P. elegans in size and position of the penetration glands.

Gynandromorphism is a condition in which an organism simultaneously exhibits male and female morphological characteristics. In Colombia, the taxon Amblyomma cajennense is represented by the species Amblyomma patinoi and Amblyomma mixtum. In September of 2014, in the Colombian Orinoco region, adult ticks were collected and determined from natural infections in bovines and equines. A gynandromorph was described from a natural infestation on a bovine, and morphologically classified as A. mixtum. This is the first literature report of a gynandromorph of A. mixtum, and the first description of a gynandromorph for a tick species in Colombia.

SummaryThe objective of this study was to compare morphological characteristics, kinetics of development, and gene expression of male and female IVP embryos that were cultured until day (D)15 (fertilization = D0), using either phosphate-buffered saline (PBS) or Milli-Q water (MQW) to dilute the agarose gel used for tunnel construction. On D11, embryos (n = 286) were placed in agarose gel tunnels diluted in PBS and MQW. Embryos were evaluated for morphology, and embryo size was recorded on D11, D12.5, D14 and D15. Then, embryos were sexed and used for gene expression analyses (G6PD, GLUT1, GLUT3, PGK1, PLAC8, KRT8, HSF1 and IFNT). The percentage of elongated embryos at D15 was higher (p < 0.05) in the PBS (54%) than in the MQW (42%) gel. However, embryos produced in MQW were bigger (p < 0.05) and had a lower expression of GLUT1 (p = 0.08) than those cultured in PBS. There was a higher proportion of male than female embryos at D15 in both treatments, MQW (65% vs. 35%; p < 0.05) and PBS (67% vs. 33%; p < 0.05); however, embryo size was not significantly different between genders. Moreover, D15 female embryos had greater expression of G6PD (p = 0.05) and KRT8 (p = 0.03) than male embryos. In conclusion, the diluent used for tunnel construction affected embryo development in the post-hatching development (PHD) system, and the use of MQW was the most indicative measure for the evaluation of embryo quality. Male and female embryos cultured from D11 to D15, either in an MQW or PBS agarose gel, demonstrated similar development but different gene expression.

Background: Few studies have been reported so far on the frequency of lower third molar impactions in patients with different morphological characteristics. Our aim in this study was to find out the frequency of impacted lower third molars in orthodontic patients with different antegonial notch depths. Material and Methods: This cross-sectional research was conducted at Orthodontics Department of Dental Section, Faisalabad Medical University, Faisalabad, and de’Montmorency College of Dentistry, Lahore, Pakistan from June 2017 to June 2019. A total of 60 orthopantomograms (OPGs) of patients with impacted lower third molars were included. The depth of antegonial notch was calculated on all the selected OPGs by measuring distance between the deepest area of the notch cavity and the tangent on the inferior border of the mandible. The patients with depth of antegonial notch of 1 mm or less were labeled as having shallow antegonial notch, while those with 3 mm or more were considered as having deep antegonial notch. Percentages and mean + SD were calculated for different variables. Depth of antegonial notching was compared between genders using ANOVA with P-value <0.5 considered as significant. Results: Of 60 orthodontic patients, there was an equal number of male and female patients (n=30). The average age of the patients was 25.5±4 years. Overall frequency of impactions was similar in both the genders and frequency of impacted lower third molars was found to be greater in patients with deeper antegonial notches. Conclusion: Mandibular third molar impactions were most frequent in orthodontic patients with deep antegonial notches

The correlation between trophic utilization and morphology was studied for two lizard species (Podarcis melisellensis and P. siculus) from two mainland localities in the eastern Adriatic area; this is the first report of trophic and morphometric data for P. melisellensis from mainland populations. Variance partitioning showed that most of the variation in morphological traits for the analyzed lizards was the result of differences between species, and to a lesser extent between sexes. Locality did not have a strong effect on the variation of morphological traits. Prey weight is the only characteristic of prey that generally exhibits correlations with morphological characteristics rather than prey size. The pattern of correlations is generally weaker for P. melisellensis than for P. siculus. Optimal foraging theory predictions were generally confirmed: P. siculus is more constrained by trophic resource availability, with a premium on larger and heavier prey consumed in the less productive locality (SM), which can be relaxed in more productive regions (KL). P. melisellensis shows such constraints only for males in the less productive region (SM). Females of both species consume heavier prey.

Ornithodoros brasiliensis is an endemic tick from Brazil and is very aggressive to humans, resulting in pain, fever andintense inflammatory response. After more than 50 years without report, this species was recently found in rural areas ofSão Francisco de Paula municipality, State of Rio Grande do Sul, southern Brazil, from where it was originally described.Herein, we describe the larva and redescribe the adults of O. brasiliensis based on scanning electron microscopy. Sincethe type was lost we designate the neotype specimen under the number IBSP 10409. In addition, the relationship betweenO. brasiliensis and other species from the Neotropical region that share the morphological characteristics of Ornithodoroswith dorsal humps on tarsi, and also live under the soil and feed on hosts other than bats, are discussed. Molecular analysisinferred from a portion of the 16S rRNA mitochondrial gene is also provided and it placed O. brasiliensis in a cluster sup-ported by a maximal bootstrap value (100%) with Ornithodoros parkeri, Ornithodoros rostratus, and Ornithodoros turicata.

The morphological characteristics of the appendicular skeleton of 26 adult fisher and 55 adult marten were studied to determine those characteristics that could be used to distinguish between species and sexes. Measurements and illustrations were used to supplement the descriptions of most bones. The appendicular skeletons of marten and fisher are similar in structure but it is possible to distinguish between the skeletal elements of these mustelids using morphometric data. Distinction can also be made between certain postcranial skeletal remains of males and females within each species using bone measurements.
