Maximum parsimony and Bayesian methods on representative material from 15 populations throughout Iran demonstrated that they did not form a monophyletic group. Strong positive correlation occurred between epipetalous filaments length to claw (EFLC), basal leaf length (BLL), basal leaf width (BLW), and plant height (PLH) with elevation. While negative correlation achieved between anthophore length (AnL) with the average air temperature and rainfall. Canonical Correspondence Analysis (CCA) showed that most morphological traits were more correlated to elevation than to average rainfall and temperature. Multivariate analysis of morphological traits with ITS analysis displayed a slight divergence between two types of regions based on their elevation.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/hacq-2023-00012024-02-16T00:00:00.000+00:00New Checklist and the Red list of the mosses (Bryophyta) of Sloveniahttps://sciendo.com/article/10.2478/hacq-2023-0006<abstract> <title style='display:none'>Abstract</title> <p>The new Checklist of mosses (Bryophyta) of Slovenia within current political boundaries comprises 669 species, 6 subspecies and 18 varieties.

Greuter & Burdethttps://sciendo.com/article/10.2478/hacq-2023-0005<abstract> <title style='display:none'>Abstract</title> <p><italic>Scutellaria rupestris</italic> subsp. <italic>cephalonica</italic> (Rech.f.) Greuter &amp; Burdet (Lamiaceae) is a perennial herb endemic to Mounts Ainos and Roudi on the island of Cephalonia. Until now, information about the taxon’s distribution has been sketchy: two fairly localized populations on Mt. Ainos have been reported, one of them extinct, and two on Mt. Roudi, without specifics. Because we thought that the taxon is much more common, we designed a survey along contours encircling the two peaks totaling 80 km. We recorded 112 locations of the taxon. We found that <italic>S. rupestris</italic> subsp. <italic>cephalonica</italic> prefers sunny clearings within fir forest as well as crevices among limestone rock on somewhat flat terrain. On Mt. Roudi, the taxon grows above 800 m, and is rather uncommon. On Mt. Ainos, the taxon is quite common above 1100 m; below that altitude it has not been confirmed. The findings were more abundant on the NE slope of Mt. Ainos which is wetter and possibly cooler than the SW slope due to being shaded and more forested, less eroded, and with a deep organic layer. The main threat to the survival of the taxon is illegal grazing. The proposed Red List assessment according to IUCN is EN B1ab(iii)+2ab(iii).</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/hacq-2023-00052024-02-16T00:00:00.000+00:00Phytosociological analysis of the Sidi Boughaba Biological Reserve, Kénitra, Moroccohttps://sciendo.com/article/10.2478/hacq-2023-0002<abstract> <title style='display:none'>Abstract</title> <p>The biological reserve of Sidi Boughaba has a unique plant biodiversity, with many animals, including birds, finding refuge there. Data on this biodiversity is old and incomplete. This phytosociological study was carried out to define the vegetation structure of the area. Stratified sampling was carried out and 124 relevés were recorded. Multivariate statistical analyses (correspondence factorial analysis and hierarchical ascending classification) used to process the relevés revealed the presence of 9 plant groups, including 4 plant associations and 5 subassociations, which belong to 3 phytosociological classes (<italic>Ammophiletea</italic>, <italic>Quercetea ilicis</italic> and <italic>Querco roboris-Fagetea sylvaticae</italic>). <italic>Quercetea ilicis</italic> is the most widespread in the area, showing several successional stages on grey and consolidated dunes.

The national park is one of the most valuable and largest protected areas in Europe – second category according to the International Union for Conservation of Nature (IUCN). Based on 786 phytosociological relevés, a total of 17 different habitat types, according to EUNIS were identified and mapped. The habitats were ecologically characterized by Ellenberg indicator values and their area was determined. A comparison was made with the areas determined in previous works. The applied method is suitable for the purposes of managing protected territories and zones, for monitoring the status and especially the conservation status of the habitats. The results and especially the established new habitats support this point of view.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/hacq-2022-00212023-06-30T00:00:00.000+00:00Rare shady chasmophytic habitat communities (8210) in Ukrainehttps://sciendo.com/article/10.2478/hacq-2022-0022<abstract> <title style='display:none'>Abstract</title> <p>The characteristics of shaded chasmophytic habitats on calcareous rocks in forest conditions are described, where the forest canopy primarily acts as a shading factor that determines microclimate, humidity and light levels.

In this work, we present the results of a phytosociological investigation of a suburban river and of its surroundings in southern Tuscany (Bestina river and its tributary Bestinino in Asciano, Province of Siena). By means of 94 phytosociological relevés, we identified 34 plant communities belonging to the 17 classes. Six habitats included in the 92/43/EEC Directive, plus two habitats recently proposed for inclusion, were identified, as well as one habitat of regional interest. The study revealed that, despite the high levels of human disturbance, aquatic and herbaceous riparian vegetation is still well-preserved, though mostly represented by stress-tolerant communities. On the contrary, most of the vegetation types not being directly linked to the river dynamic are in poor conservation status. Despite this, some habitats of community interest were detected even in non-riverine sites. Our work provides the basic knowledge for future restoration of the Bestina river and of its surroundings, wished by the Tuscany Region.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/hacq-2022-00162023-06-30T00:00:00.000+00:00Diversity of (L.)
