Aquatic insect communities in inland waters of Chile are characterised by the presence of certain species depending on water quality, but there is little information on statistical ecology in the structure of insect communities. The aim of the present study was to apply null models to explain the structure of aquatic insects in the middle zone of the Loa River, in the Atacama Desert (Antofagasta Region, Chile; 23°S). The results of the null models of species co-occurrence showed that species associations are random, while niche sharing showed that species share ecological niches and consequently there is interspecific competition. The reported taxa are similar to communities for other North Patagonian rivers in terms of community structure.

Birds associated with aquatic environments have diverse locomotor and foraging strategies. We hypothesize that aquatic birds have different covariation patterns in the shapes of the sternum and pelvis depending on the locomotor mode and the predominant use of wings or hind limbs when moving through the water. The study was conducted on 26 bird species, among which we identified three ecological categories: surface swimmers, wing- and foot-propelled divers. The last two categories included only species that dive from the water surface. Geometric morphometric methods were applied to analyze shapes, and covariance was investigated with two-block PLS analysis. We show that wing- and foot-propelled divers have different patterns of covariation between sternum and pelvis shapes. A narrower, elongated and flattened sternum correlates with a shortened postacetabular region of a pelvis in wing-propelled divers. A widened and shortened sternum with a deep keel correlates with an elongated post-acetabular region of a pelvis in foot-propelled divers. Surface swimmers have a wide variety of combinations of sternum and pelvis shapes, which is apparently explained by their lower specialization for specific aquatic locomotion, and by the influence of diverse ecological factors.

The first insect-targeted study of the European mistletoe, Viscum album L., was conducted in Ukraine. In total, 35 species of insects reared from mistletoe were identified to belong to 5 orders, 20 families and 34 genera. Twenty-seven identified species were reared from mistletoe for the first time, including 17 species of Hymenoptera, 8 species of Coleoptera and 2 species of Diptera. Our results revealed significant gaps in knowledge about insects associated with mistletoe. This is appeared in the fact that more than 77 % of the insects we reared have never been detected on mistletoe before. It is obviously that 70 % to 90 % of the insects associated with mistletoe remain unknown. We also found a highly probable tripartite link between the European mistletoe, parasitic fungus Sphaeropsis visci and the saproxylic and mycetophagous Coleoptera. The in[1]teraction of Coleoptera with S. visci is facultatively mutualistic, and beetles act as vectors to spread spores and mycelium among mistletoes. In addition, we found the mass breading of invasive species Leiopus femoratus on V. album. Hence, V. album might play a crucial role in the mass and rapid invasion of L. femoratus in Europe.

Characters of taxonomy and evolutionary scenario based on genetic differentiation of generic groups of forest and field mice Apodemus s. l. were established by analyzing the variability of the cyt-b (cytochrome-1, cytb) gene. For this purpose, 124 sequences of Apodemus s. l. and other Palaearctic Muridae genera (Mus, Micromys, Rattus) were downloaded from GenBank. The adequacy of the categories of semispecies, allospecies, species, whose genetic differentiation corresponds to GD ranges of 0.03–0.06, 0.06–0.1 and 0.1–0.15, has been proven. Within the genus Sylvaemus the following species are recognised: S. (Sylvaemus) alpicola, S. (S.) arianus (= witherbyi), S. (S.) flavicollis, S. (S.) hyrcanicus, S. (S.) ponticus, S. (S.) (superspecies) sylvaticus, S. (S.) (superspecies) uralensis, S. (Karstomys) epimelas, S. (K.) mystacinus, S. rusiges: within Apodemus: A. agrarius, A. chevrieri, within Alsomys: Al. argenteus, Al. (superspecies) major (= peninsulae), Al. nigrus, Al. semotus, Al. speciosus. Generic taxonomy remains ambiguous, which is caused not only by different scales of differentiation of most species of Western and Eastern Palaearctic lineages, but also by the lack of information on key genus-specific characters: the number of roots on upper molars and number of mammary glands for most East Asian species.

All existing data and most of the available materials on Sphyradium doliolum from Ukraine and Moldova are reviewed. The species is reported from 38 localities (some including several sites) on uplands east of the Carpathians, the Dnipro Upland and in the Crimean Mountains. It mostly inhabits the broadleaved forests, but in one locality was found in a forestless rocky meadow steppe at an altitude of ca. 1400 m in the Crimea. Statistical analysis of the morphometric shell characters shows a significant geographical variability between the populations of S. doliolum from the different parts of Ukraine and Moldova. The most prominent morphometric differences were found between the populations from the Crimean Mountains and from all other East European populations combined. An origin of S. doliolum in Eastern Europe is discussed. The results of the morphometric analyses support the hypothesis of the two different origins during the two separate periods for the populations of S. doliolum in the Crimean Mountains and in the East European Plain. These two groups of populations could be representing the two different lineages that perhaps could be of the two different subspecies, but their status requires additional studies involving molecular genetic methods and material from a wider area.

This paper presents the original data on studies of populations of guppies on the territory of Ukraine on the example of those of them surviving for many years in the drainage system of Kyiv. For 10 years, wild populations of guppies and their morphological features were studied in the warm water flows of the Bortnychi aeration station in Kyiv (2011–2020). During this period, the original “key” was developed to describe the morphology of their coloration peculiarities, which includes: total length, the number of pattern and coloration elements (4 types, 9 elements), pigmented area (light — orange, dark, pigmentation index), the shape and pigmentation of the tail (6 types) and its asymmetry At present, in the countries of Eastern Europe, the species is not adapted to any waters in the wild due to low winter temperatures, but these fish have become well established in sewage and other warm water bodies in urbanized areas (cities, towns, factories, etc.). We described the places where this invasive species had been found for many years, highlighting its key features. Thanks to GIS modelling, it was revealed that the existence of wild populations of guppies in Ukraine and Latvia is possible only in warm waters (currently mainly sewage systems of big cities) within anthropogenic territories. Such a key and study of relatively isolated populations of invasive species will provide a deeper understanding of micro-evolution of their morphological features (coloration) in isolation, help to track distribution of invasive species in a changing climate and provide material for comparison with possible similar invasions in areas heavily affected by military actions.

Based on workers from the Late Eocene Rovno amber (Ukraine), Damzenomyrmex gen. n. (Dlichoderinae) is established to include Damzenomyrmex ribbeckei sp. n., which is described here. I consider Damzenomyrmex to be a relative of Dolichoderus s. l. and assign it to the tribe Dolichoderini. Damzenomyrmex differs well from representatives of the previously established subgenera (genera) of Dolichoderus s. l., such as Dolichoderus s. str., Karawajewella, Acanthoclinea, Monoceratoclinea and Diceratoclinea by the nature of the mesosomal armature. It differs from the species of Hypoclinea in the presence of horn-like projections on the anterolateral corners of the pronotum. Regarding the last character, Damzenomyrmex reminds the species of Monacis, but readily differs from them by the non-concave posterior propodeal margin, a different shape of the petiolar scale, a not laterally marginated mesonotum, and some other characters. Furthermore, Damzenomyrmex differs from all Dolichoderus s. l. species in the cuticular structure and in the serration pattern of the mandibles, with the masticatory margin having 6–7 minor sharp teeth and a much longer apical one, the basal angle distinct and the basal margin lacking teeth or denticles. The comparative composition of Dolichoderinae and representatives of other ant subfamilies in late Eocene European ambers is considered.

For the ongoing range shifts under climate change, it is essential to have reference information on the current presence of the species. In recent years, there has been an increase in observations of thermophilic reptiles outside their historical range in Ukraine. The distribution of the Caspian whipsnake, a common snake in southern Ukraine, appeared to be poorly documented at the northern edge of its range due to low density under sub-optimal conditions at the edge of the range. Here we provide verified observations of the Caspian whipsnake from the Mohyliv-Podilsky (formerly Yampil) district of the Vinnytsia region. These data considerably extend and specify the north-western limit of the range and, together with accompanying data on the frequency of species observations, support the hypothesis of a northward shift in the range of the species and/or a strong recent increase in the abundance of the species.

Motor stereotypic behaviors (MSBs) are a kind of repetitive behaviors performed by stressed animals and are more common in captivity. This study aimed to assess whether the MSB in captive rhesus monkeys varies between males and females, and with the extent of visitor-monkey interactions. A group of six rhesus monkeys (two adult males and four adult females; among females, two were rescued from the wild and two were captive-born) housed in the Central Zoo, Kathmandu Nepal were sampled in the study. Behavioral observations were done by focal animal sampling for 30 minutes in each session from 8:00 AM till 10:00 AM in the absence of visitors and 10:00 AM–12:00 PM in the presence of visitors. At every 10 minutes interval, the number of visitors around the cage and the level of visitor-monkey interactions were scanned. Pacing and bounce were the MSBs performed by the zoo rhesus monkeys. Females, especially the rescued ones, performed significantly more MSBs than the males. An increase in visitor-monkey interaction involved the monkeys into more begging and feeding, which in turn lowered the MSBs. The findings of this study indicate that interactive enrichment such as feeding and visitor-monkey interactions help to reduce MSBs in zoo monkeys.

Females, especially the rescued ones, performed significantly more MSBs than the males. An increase in visitor-monkey interaction involved the monkeys into more begging and feeding, which in turn lowered the MSBs. The findings of this study indicate that interactive enrichment such as feeding and visitor-monkey interactions help to reduce MSBs in zoo monkeys.","PeriodicalId":36290,"journal":{"name":"Zoodiversity","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67088972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
