The behaviour of spiders is controlled by the central nervous system like in other animals. Spiders contain several types of sensory organs that help them recognize their surroundings. These sensory organs may have mechanoreceptor or chemoreceptor functions. All parts of the spider’s body contain different hairs, sensillae, setae and spines. The function of sensory structures is affected by their site in the spider’s body. This study aimed at describing different types, distribution and functions of sensory organs of five ground spiders inhabiting Assiut Governorate, Egypt. Fifty samples of spider specimens were collected by hand picking and pitfall traps during years 2016 and 2017 from different habitats. The specimens were examined under a binocular stereomicroscope and scanning electron microscope. The study revealed the presence of sensory organs on different body parts of the studied spiders, including sensilla trichodea, sensilla placodea, sensilla basiconica, sensilla styloconica, setae, trichobothria and slit sense organs (Lyriform organs). A significant difference in the position and type of sensory organs was detected between males and females of different spider species.","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"61 21 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141939530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It prefers to feed on the annual leaves of an important economic plant, Pterocarya stenoptera (Fagales: Juglandaceae), and causes extensive cosmetic destruction, even plant death. Nevertheless, its biological characteristics are mostly unknown. In this study, we investigate the harmful and biological characteristics of G. depressa with different developmental stages. The results showed that G. depressa had four developmental stages: egg, larva (1st -3rd instar), pupa, and adult, the life history lasted nine days, with obvious overlapping generations. The food intake of the larvae increased with the increase of the instar, and the maximum food intake of the 3rd instar larvae was 448.19 mm2. The abdomen of the females was enlarged before oviposition, and the average number of eggs laid was 47.63 ± 13.53. Bioassay showed that there was no difference in the search time for the young (2.03, 1.25, 1.15, and 0.91 min) and old leaves (1.68, 1.15, 0.90, and 1.93 min) of P. stenoptera between 1st -3rd instar larvae and adults; the feeding preference of 1st -3rd instar larvae and adults for young leaves was higher than that to old leaves (23.33%, 26.67%, 33.33%, and 21.67%, respectively).

These strategies, such as chemical signals and calling songs, fuel competition for mates and can lead to the evolution of distinct courtship behaviours within a species. These behaviours often involve males and females taking on different roles in attracting mates. For example, limitations in signal production or perception can make one of the sexes sedentary. Regarding Poecilimon bushcrickets specifically, in 2012 McCartney et al. proposed a theory to explain sex role differentiation within the mate-searching system in certain species. According to this model, sex roles in mate-searching systems propose that in species where females search for males, females should receive a larger spermatophore gift. This study tests this theory for two Poecilimon species with differing strategies in terms of females’ response to male calling songs regarding spermatophore investment (P. sureyanus-female searching and P. inflatus-male searching). Given that reproductive effort and physiological activities are both costly for the organism, there is a trade-off due to limited energy resources. To investigate the specific trade-off in allocating resources between reproductive functions and immune defence in these species, the presents study compared two immune parameters (phenoloxidase and lytic activities). In nature, immune activities are much more plastic than the differentiation of reproductive traits between the sexes. The results showed that spermatophore investment may critically depend on differences in mate-searching strategies, particularly in terms of females’ response to male calling songs within the species. The findings also indicated that there may be trade-offs between the costs related to reproduction and the immune system.","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"184 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141881769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cells' viability from the PHEMA-NVF cryogels exhibited a significant drop of 23.96 ± 1.44% compared to the plain PHEMA cryogel, which served as the control group without NVF. Additionally, this cryogel caused blebbing and holes on the cell surface. Despite the gradual increase in TOS levels with increasing NVF amounts, only the cryogel containing 3.12 mmol NVF showed a statistically significant difference from the control. The gradual increases in TAS levels in response to cellular stress were recorded depending on the increase in NVF amounts up to 3.12 mmol. While the enzymatic antioxidant system was generally induced in cells released from the cryogel prepared with relatively low levels of NVF, these activities dramatically decreased at higher amounts of the comonomer. Finally, FTIR analysis revealed that the highest concentration of NVF caused protein degradation and increased the relative concentration of lipid and polysaccharide molecules. Therefore, we can suggest that this comonomer induces oxidative stress, which the cell cannot tolerate beyond a certain threshold.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"215 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141881683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a comprehensive understanding of small mammal diversity requires integrative taxonomic approaches due to the cryptic nature and sympatric distribution of some taxa. Here, to develop a DNA barcode library, we re-evaluated the small mammal diversity of Georgia.Samples for DNA studies were collected during the last nine years throughout Georgia. The Cytochrome Oxidase Subunit I (COI) region of the mitochondrial genome was barcoded for collected samples, and a DNA barcode library was assembled. As a result, nearly 80% of the known species of Georgian small mammals were covered. Two species, Microtus rossiaemeridionalis (Ognev, 1924) and Myotis tschuliensis (Kuzyakin, 1935), were detected for the first time in Georgia.

Its identity was verified by sequencing of ITS and 28 S nrDNA regions. The analysis of trophic status by stable-isotope ratio of carbon and nitrogen suggested that the species is probably ectomycorrhizal. For the seventeen sampling sites, environmental data were obtained and information on landscape development and management were retrieved from historical maps and aerial orthophotographs. All these parameters were analysed by multivariate ordination methods. In Slovakia, P. macrorhizum is found in thermophilous to mesophilous stands on acidic soils with a pH ranging from 4.1 to 6.2. These habitats are dominated by Quercus cerris, with non-frequent tree taxa of Carpinus betulus and Quercus petraea agg. The key environmental drivers shaping the habitat of P. macrorhizum were identified as time since deforestation, with the presence of old Q. cerris individuals (former solitary trees of pastures) and soil characteristics. The fungus appears to be a species of transitional habitats historically affected by grazing. These transitions occur between thermophilic and mesophilic sites, including oak forest communities, dry steppic grasslands and forest edges, as well as spontaneously overgrown pastures and forests with a closed canopy. It is regrettable that the Q. cerris stands in Slovakia are under threat, particularly because of felling and the lack of grazing in forests. Furthermore, recent silvicultural practices have resulted in the replacement of oaks (Quercus spp.) by hornbeam (Carpinus betulus) and the formation of closed stands.","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"165 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
