Micromorphology of Pine Needle Primordia and Young Needles after Bud Dormancy Breaking.

Using a scanning electron microscope, the micromorphologies of needle primordia and the young needles of seven pine species (, , , , , , and ) were analyzed at phenological stages B2 and B3 (according to Debazac). In B2, needle tips were rounded or pointed, depending on the species. In and , teeth were noted on the tips.

Integrative taxonomy reveals new, widely distributed tardigrade species of the genus Paramacrobiotus (Eutardigrada: Macrobiotidae).

In a moss sample collected in Ribeiro Frio, Madeira, Paramacrobiotus gadabouti sp. nov. was found and described using the integrative taxonomy approach.

Morphological diversification of alien and native aquatic snails of the genus Physa and Aplexa (Gastropoda: Physidae) of Western and Central European range.

This is the first comparative study on alien and native Physidae (Gastropoda: Heterobranchia) from Western and Central Europe. Morphology, ecological features and distribution are presented for each physid species. We analysed taxonomical features of physid snails from Europe in great detail.

Reflectance spectroscopy and machine learning as a tool for the categorization of twin species based on the example of the Diachrysia genus.

In our work we used noninvasive point reflectance spectroscopy in the range from 400 to 2100 nm coupled with machine learning to study scales on the brown and golden iridescent areas on the dorsal side of the forewing of Diachrysia chrysitis and D. stenochrysis. We used our approach to distinguish between these species of moths.

Taxonomic Significance of Seed Morphology in L. (Plantaginaceae) Species from Central Europe.

In this study, 1159 seeds of 29 Central European species of the genus were analyzed based on scanning electron microscopy images. The species belonged to nine subgenera: , , , , , , , and , following the newest phylogenetic classification of the genus. Nine measured characteristics of seeds and nine ratios were analyzed statistically using ANOVA followed by post hoc testing, cluster analysis and discriminant analysis.

An integrative description of Diploechiniscus oihonnae/ (Richters, 1903) population from near the original type locality in Merok (Norway).

In the present study, we used integrative taxonomy to describe a population of Diploechiniscus oihonnae (Richters, 1903) from the neotype locality in Merok (Norway). We found no differences in the chaetotaxy formula between the life stages and sex of Dpl. oihonnae.

Integrative description of five Pseudechiniscus species (Heterotardigrada: Echiniscidae: the suillus-facettalis complex).

Pseudechiniscus is a morphologically homogeneous heterotardigrade genus with a relatively low number of morphological features useful for the species discrimination. The species of the Pseudechiniscus suillus-facettalis complex are some of the most challenging tardigrades to identify. Here, we examine several populations from Antarctica, Italy, Madagascar and Norway that would have most likely been attributed to Pse.

Variability of Echiniscus tristis Gąsiorek & Kristensen, 2018-is morphology sufficient for taxonomic differentiation of Echiniscidae?

The majority of species in the genus Echiniscus (Heterotardigrada) have been described based on differences in the chaetotaxy or dorsal sculpture. Dorsal sculpture is, in general, considered to be species-specific and not very variable; however, many problems have arisen due to various interpretations of microscope images, which has led to taxonomic confusion in the genus Echiniscus. Conversely, chaetotaxy is generally much easier to interpret, even using low-quality microscope optics.

Preliminary evaluation of application of a 3-dimensional network structure of siloxanes Dergall preparation on chick embryo development and microbiological status of eggshells.

The spatial network structure of Dergall is based on substances nontoxic to humans and the environment which, when applied on solid surfaces, creates a coating that reduces bacterial cell adhesion. The bacteriostatic properties of siloxanes are based on a purely physical action mechanism which excludes development of drug-resistant microorganisms. The aims of the present study were to 1) evaluate a Dergall layer formed on the eggshell surface regarding the potential harmful effects on the chick embryo; 2) evaluate antimicrobial activity and estimate the prolongation time of Dergall's potential antimicrobial activity.

Integrative description of bisexual Paramacrobiotus experimentalis sp. nov. (Macrobiotidae) from republic of Madagascar (Africa) with microbiome analysis.

In a moss samples collected on Madagascar two populations of Paramacrobiotus experimentalis sp. nov. were found.

Two new species of Tardigrada from Ecuador (South America).

In two moss samples collected in El Cajas National Park (Azuay Province, Ecuador), 33 specimens and 19 eggs of a new species of Macrobiotus and 56 heterotardigrades belonging to a new Echiniscus species were extracted. Macrobiotus dulciporus sp. nov.

An integrative redescription of the nominal taxon for the Mesobiotus harmsworthi group (Tardigrada: Macrobiotidae) leads to descriptions of two new Mesobiotus species from Arctic.

The Mesobiotus harmsworthi group has a global distribution, with localities in polar, temperate and tropical zones. Since the first species of the harmsworthi group was described in the beginning of the 20th century, tens of new species within the group were found and named. However, the diagnosis of the nominal Mesobiotus harmsworthi is insufficient and enigmatic, thus it can be is a serious obstacle in solving the taxonomy of this group.

An integrative description of a new tardigrade species Mesobiotus romani sp. nov. (Macrobiotidae: harmsworthi group) from the Ecuadorian Pacific coast.

In a mixed moss and lichen sample collected in Esmeraldas Province in north-western Ecuador, 20 tardigrades and 11 eggs, belonging to a new species of the genus Mesobiotus, were found. In addition to the traditional taxonomic description with morphometrics, light and scanning microscopy imaging, we also provide nucleotide sequences of three nuclear (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial (COI) DNA fragments of the new species. Based on the egg chorion morphology, Mesobiotus romani sp.

Cylapofulvidius Chérot & Gorczyca, 2000-a synonym of Fulvidius Poppius, 1909 (Hemiptera: Heteroptera: Miridae: Cylapinae).

The genus Cylapofulvidius Chérot & Gorczyca, 2000 is proposed as a junior subjective synonym of Fulvidius Poppius, 1909 syn. nov. and all members of Cylapofulvidius are transferred to the genus Fulvidius.
