Algal habitat-forming forests composed of fucalean brown seaweeds (Cystoseira, Ericaria, and Gongolaria) have severely declined along the Mediterranean coasts, endangering the maintenance of essential ecosystem services. Numerous factors determine the loss of these assemblages and operate at different spatial scales, which must be identified to plan conservation and restoration actions. To explore the critical stressors (natural and anthropogenic) that may cause habitat degradation, we investigated (a) the patterns of variability of fucalean forests in percentage cover (abundance) at three spatial scales (location, forest, transect) by visual estimates and or photographic sampling to identify relevant spatial scales of variation, (b) the correlation between semi-quantitative anthropogenic stressors, individually or cumulatively (MA-LUSI index), including natural stressors (confinement, sea urchin grazing), and percentage cover of functional groups (perennial, semi-perennial) at forest spatial scale. The results showed that impacts from mariculture and urbanization seem to be the main stressors affecting habitat-forming species. In particular, while mariculture, urbanization, and cumulative anthropogenic stress negatively correlated with the percentage cover of perennial fucalean species, the same stressors were positively correlated with the percentage cover of the semi-perennial Cystoseira compressa and C. compressa subsp. pustulata. Our results indicate that human impacts can determine spatial patterns in these fragmented and heterogeneous marine habitats, thus stressing the need of carefully considering scale-dependent ecological processes to support conservation and restoration.

Abstract:The purpose of this paper is the morphometric study as well as the assessment of population structure of the Testudo hermani tortoise in the Vlora area. Individuals are collected in the study area. A morphometric study is made for the caught individuals. Suitable habitats have been identified for their growth and development. It is estimated the number of healthy or unhealthy individuals, dead individuals and also the identification of the local population's threatening factors. Individuals with anomalies are studied and then compared with normal individuals, especially in terms of the number and shape of the dermal plates.

Class Шplays an important role in natural ecosystems, because it supports biodiversity and soil stability, and a change in the number or distribution of centipede species can indicate changes in the environment, such as pollution, soil degradation, climate change, etc. The purpose of the study is to identify the existing species of soil animals of the Diplopoda class, as well as to determine environmental factors that can affect their distribution. Species’ diversity was assessed by collecting individuals and classifying them into order, family, genus, and species. Climatic factors, namely temperature and precipitation, are also determined. As a result of the study, ecological aspects of centipede development were evaluated and their distribution and dependence on environmental factors, such as climatic, edaphic, and trophic factors, were analysed. In the southern region of Albania, 22 species of the Diplopoda class of the Myriapoda group were identified, among which mainly decomposers of organic remains and phytophages. The regions of Llogara and Šhašhica were noted as the regions with the highest diversity of millipedes. In addition, it was established that the variation of species is influenced by the environment, the presence of organic substances, and climatic factors. Temperature and humidity are determining factors influencing the distribution of the Diplopoda class in different biotopes. Species that have a large regional distribution and are most widespread in time throughout the year: Pachyiulus cattarensis, found in the period June-November, Glomeris pulchra – May-July, SeptemberOctober, Pachyiulus varius – May-October. A less active period was noted for the following species: Polydesmus complanatus, Glomeris latermarginata, Typhloiulus albanichus, Pachyiulus hungaricus, Glomeris pustullata. The research, which was carried out, is of practical importance for nature conservation, as the Diplopoda class plays an important role in maintaining ecosystems and biodiversity and can be an indicator of the state of the environment

Recently, the problem of preserving biodiversity on the planet has become increasingly relevant. Therefore, research on the ecological characteristics of organisms that play an important role in the functioning of biogeocoenoses is especially relevant. Chilipoda millipedes are one of these groups. Currently, many questions on the ecology of Chilopods, especially in the territory of Albania, remain unresolved. This motivates researchers to seek answers to these issues. The primary research aim is to analyse the specific features of the ecology of the Chilipoda millipedes inhabiting Vlora. The material used for the study was the author's collections of centipedes. Manual collection and soil sampling methods were used in the research. Determination of the taxonomic affiliation of centipedes was performed by examining the morphological features of centipedes under a stereoscopic microscope and further determining specimens with the help of determination keys. In the field under investigation, the Chilipoda fauna is represented by 6 species from 4 orders, 6 genera, and 5 families. Temperature and humidity have been shown to have a significant influence on the geographical distribution of chilopods: thus, the occurrence of centipedes in litter and the upper soil layer decreases significantly with the onset of drought. The character of flora plays a secondary role in the distribution of centipedes. It was established that soils with high content of humus and nitrogen are a favourable habitat for centipedes. The paper presents, for the first time for the Vlora region, data on the vertical distribution of S. coleoptrata along the soil profile. Scootigers preferred litter and did not migrate into the soil. Other representatives of Chilipoda were mainly found in the uppermost soil layer (0-10 cm), moreover Chilipoda were concentrated in the litter, and only a small part of them descended to a depth of 20 cm. The obtained results contribute to the knowledge of the ecological features of chilopods
