“…This finding is in accordance with that of Abdulgabar (2019) in Assiut Governorate. Brigića et al, (2019) showed that the isopod Ligidium germanicum exhibited its highest densities of seasonal activity during spring and early summer. However, it contradicts the observations made by Bedair (1991), Kayed et al, (1991) in Ismalia region, Egypt and Abd El-Wakeil (2005) in Assiut Governorate, Egypt who reported the highest abundance of Porcellio laevis during the spring season.…”

Soil arthropods represent a wide range of ecological functions, and their abundance and diversity can be used as an indicator of healthy soils. Thus, the species composition of soil macroarthropods at six different localities in Qena Governorate was carried out during one year extended from March 2021 to February 2022. The sites of collection differ in their soil structure, environmental factors and vegetation. The study revealed that the total number of soil macroarthropods collected was (7854 individuals) and could be attributed to four different classes (Insecta, Crustacea, Arachnida and Chilopoda), 13 orders, 36 families, 54 genera, 45 species and 3 unidentified taxa. The highest value of total abundance of macroarthropods was registered during spring and the lowest was in winter. Site IV (El-Taramsa) recorded the highest density of the collected specimens (3097 individuals), while the lowest value (392 indvs.) was recorded at site I (Nag Hammadi). Insecta was the dominant group; it represented about 63.13% of the total density followed by Crustacea (31.41%), Arachnida (5.20%) and Chilopoda (0.26 %). Taxa richness reached the highest peak (38 taxa) at sites III (SVU farm) and IV (El-Taramsa), while the lowest peak (20 taxa) was detected at site VI (Laqita). Shannon-Wiener's diversity index ranged between (1.328) at site VI and (2.393) at site III.

“…Besides the competition for high quality food reduces juvenile growth and directly affects the population density (Rushton & Hassal, 1987). The researchers noticed that the isopods are unevenly distributed (Brigic et al, 2019), and their distribution depends on the litter mass and loss due to forest fires : such areas are repopulated by woodlice reluctantly (Gongalsky et al, 2005). The increase in the abundance of Isopoda (+323%) and some other soil dweller groups is caused by irrigation (Johnson et al, 2018).…”

Influence of saprophages (Isopoda, Diplopoda) on leaf litter decomposition under different levels of humidification and chemical loading

et al. 2020

The paper presents a study about the influence of two saprophage groups (Isopoda, Diplopoda) on leaf litter decomposition under different levels of humidification and chemical stress. Because of their worldwide distribution, we focused on the common pillbug Armadillidium vulgare (Latreille, 1804) (Isopoda, Armadillidiidae), and the common millipede species Rossiulus kessleri (Lohmander, 1927) (Julida, Julidae). The function of environment creation by the given saprophages, as destructors of dead plant matter, supporting such ecosystem services as soil fertility improvement and nutrients’ turnover, is highlighted. To conduct the experiment, the animals were collected manually and using pitfall trapping. In order to bring the experimental conditions closer to the natural, the individuals were not sexed. The maximum consumption of leaf litter by woodlice was recorded in the conditions with adequate moisture (0.5 mL of distilled water per box) and amounted to 2.52 mg/10 individuals per day, which exceeds its consumption with low and increased moisture, respectively, by 1.82 and 1.24 times. As for the effect of interaction, the consumption of maple litter with optimal moisture (4.77 mg/10 individuals per day) was the greatest. The largest absolute difference between broad-leaved tree species in the average weight of leaf litter consumed by woodlice was between maple leaf litter and oak leaf litter, the minimum – between robinia leaf litter and oak leaf litter. According to the results of the obtained data (Diplopoda), it can be stated that there is a statistically significant effect of chemical stress and discrepancy of the average zinc content in the object of study (in Diplopoda and their faecal pellets). We found that the diet provided did not affect the distribution of zinc in Diplopoda under conditions of chemical stress. According to the results of pairwise comparisons, we determined that the zinc content in the Diplopoda clearly differs for control and almost every concentration of zinc sulfate solution – 0.03 and 0.15 g/L, the samples of which do not form a homogeneous group. The species composition, abundance and distribution in space of soil invertebrates are informative indicators which reflect the ecological state of soils, intensity in development of soil horizons as well as intensity of processes occurring in them.

“…The latter, together with Betula pendula , Frangula alnus and Alnus glutinosa , are rapidly colonising open habitats and pool margins in the peat bogs of the Western Balkans (Alegro & Šegota, 2008; Topić & Stančić, 2006). Progressive successional changes have seriously affected terrestrial invertebrates, causing changes in species assemblages (e.g., Brigić et al, 2017, 2019; Bujan et al, 2015). However, these distinctive habitats still harbour rare species that are globally endangered and included in the European Habitats and Species Directive (Annex II and IV), and those with notable national status included in the Red Lists (Brigić et al, 2017; Franković & Bogdanović, 2008; Nikolić & Topić, 2005).…”

Microhabitat distribution of aquatic oligochaete communities in the Western Balkans peat bog

et al. 2021

Peat bog pools are rare and fragmented in the Western Balkans. Thus, aquatic macroinvertebrate diversity and the implications for microhabitat loss in these ecosystems are poorly known. Aquatic oligochaetes, widely used as indicators, were sampled using a benthos net in the largest and oldest Croatian bog, in four main water body types: a pond, a deep pool, a shallow pool and a ditch. As these microhabitats lack spatial replication both in the studied bog and in the region, we applied a nested study design with replicates sampled over time. We found a species‐rich aquatic oligochaete fauna, with 11 taxa recorded. Oligochaete communities were strongly affected by vegetation complexity and the morphology of bog water bodies, namely, their size and depth. As revealed by generalised linear mixed models (GLMMs), taxon richness and abundance were significantly higher in the ditch than in other water body types. This could be attributed to the vegetation complexity, supporting many different niches and providing allochthonous food supplies for oligochaetes. The various bog pools contribute to regional biodiversity and promote distinct patterns in the spatial distribution of oligochaetes. However, the predominance of ubiquitous oligochaetes, with high taxon richness, might indicate the degradation of the studied peat bog. This was further confirmed by the spread of vascular plants to the bog area and higher pH water values. All these warning signals suggest that hydro‐ecological conditions should be urgently improved in order to preserve communities in the bog studied.
