The water content of vegetation is considered a key parameter for ecological analysis as well as for agricultural and forestry applications. Remote sensing methods offer significant advantages over traditional field methods for determining the water content of vegetation at the leaf, canopy, and landscape levels. In this study, the potential of hyperspectral vegetation indices in predicting canopy water content in grasslands was evaluated. For this purpose, data were collected from 3 several grasslands located at ~500 m, ~1200 m and ~1400 m altitudes. 71 samples were collected from each study area, and a total of 213 samples were analyzed. In this context, 59 ratio-based hyperspectral vegetation indices were tested. The relationship between canopy water content and hyperspectral vegetation indices was evaluated with linear, exponential, logarithmic and power regression models. The results showed that the NW-3 (920,970) index significantly represents the canopy water content variable. It was determined that the exponential regression model created with this index was able to explain the variations in canopy water content up to 85%. On the other hand, it has been detected that the high level of water content in the vegetation creates a significant saturation problem. Another finding of this study is that the predictive power reaches higher levels in low canopy water content characteristics. The results of this study show that in situ hyperspectral data has a very high potential in determining vegetation water content in grasslands.

A former lectotype for Bromus cincinnatus Ten. (Poaceae) has been superseded, as it is in serious conflict with the protologue. Another element of the protologue has been designated as the effective lectotype. The new lectotype is identified as coespecific with Bromus intermedius Guss., a Mediterranean species of Bromus L. subg. Bromus. The new combination Helictochloa panormitana (Lojac.) Romero Zarco is proposed for the species originally described as Avena australis Parl., nom. illeg., which is currently known as Helictochloa cincinnata auct. The lectotypes of Avena panormitana Lojac., Avena opulenta Lojac., and Bromus intermedius Guss. are also designated.

The genus Quercus is known for its taxonomic complexity that is characterized by the abundant morphologicaldiversity and phenomena of hybridization and introgression found in a number of its species. The number of taxacontinues to change and evolve despite systematists’ attempts to clarify and simplify it. The Quercus faginea s.l. complexrepresents one of the most conclusive and complex examples found in the North-Western Mediterranean and North Africa.Nevertheless, the systematics of this complex have undergone a remarkable evolution from the first Lamarckian taxa Q.lusitanica and Q. faginea to the present day, especially in the Iberian Peninsula, Tunisia, and Algeria, by virtue of therecognized taxa. To compare Moroccan taxa with those found in other regions, as well as update the taxonomic status ofpopulations found in Morocco, data found in a corresponding bibliography was used for a critical and objective analysis.Although the taxonomic situation remains unresolved, the analysis found that there is a likely presence of the fagineavariety in Morocco, while also anticipating the confirmation of a new morphological analysis that accounts for the stablecriteria used for an infraspecific distinction. The rest of Morocco’s stands seem to be represented by Q. canariensis andQ. faginea subsp. broteroi. Considering the uncertain existence of maroccana, further study of its distinct morphologicaland biogeographical peculiarity is required.

The types of five taxa described with material from northern Africa have been revised, yielding the following results: Barbula commutata var. erosa Corb. is synomyzed with Streblotrichum convolutum var. commutatum; Bryum trabutii Thér. with Ptychostomum rubens; Thamnium alopecurum var. decipiens Corb. with Scorpiurium circinatum; and Trichostomum mediterraneum var. algeriae Müll. Hal. ex Geh. with Hydrogonium bolleanum. Funaria altissima Dixon is recognized as a distinct species, for which we provide a full description, photographs, and a key to the more closely species. Lectotypes have been designated for all names except for F. altissima. The identity of two nomina nuda is also resolved: Funaria hygrometrica var. dentata Corb. ex Maire & Werner, corresponds to typical Funaria hygrometrica, and Zygodon dimorphus Thér. ex Jelenc is here identified as Grimmia torquata¸ an interesting addition to the bryophyte flora of Morocco and continental Africa. Ptychostomum rubens is reported for the first time from Algeria.

Beech forests are considered one of the most emblematic ecosystems in the temperate deciduous broadleaf forest biome and host a wide variety of specialised cryptogamic organisms such as epiphytic lichens. This checklist is the first compilation focused on the epiphytic lichen diversity occurring on Fagus sylvatica L. trees along Europe. The checklist is based on a literature search encompassing 137 studies. We report 683 lichen species differently distributed across 26 European countries. The reported richness of the lichen species ranged from one in Kosovo and Netherlands to 331 species in Ukraine. All information provided in this manuscript is available online (http://biodiversos.org/epidiversity-lichens-fagus-europe/) to facilitate the accessibility and updating of the data. Thus, we aim that this checklist becomes an open and dynamic database that continuously expands not only based on new lichenological studies, but also with the information retrieved by lichenologist in the past, data published in a diverse suite of languages and herbarium records.

High-mountain peatlands are essential ecosystems for habitats, biodiversity, water, and carbon cycling, butthere is little comprehensive information in central Iberia. We present results of research concerning the distribution,geormorphology, floristic, geobotany, and habitat diversity of peatlands in the Gredos Regional Park (Iberian Central System).We identified 72 peatlands covering 117 ha and ranging in size from 0.01 to 17.34 ha. Peatlands occur primarily in theupper orosubmediterranean bioclimatic belt at 1775–2230 m asl. From a geomorphological point of view, 9 differentpeatland typologies have been defined. Multivariate analyses (agglomerative cluster analysis and principal componentanalysis) of 103 relevés allowed us to classify the sampled peatland stands into 7 plant communities and 4 Europeanhabitats that formed along complex hydrogeomorphic conditions, and to propose a new subassociation of other communitypreviously described (Caricetum echinato-nigrae lycopodielletosum inundatae). The main threat to Gredenseanpeatlands is pastoral pressure, which affects 15 of them intensively, mainly between the upper supramediterranean andthe lower orosubmediterranean bioclimatic belts (~1314–1700 m asl). Seven bryophytes and three vascular plantsdocumented in the Gredos Regional Park peatlands are included in the IUCN Red List. From the point of view ofconservation priority, the most threatened correspond to transition mires communities (Habitat 7140) growing inoligotrophic and minerotrophic peatlands (Caricion nigrae vegetation). Particularly, the Iberian Central System endemicSedo lagascae-Eriophoretum latifolii association is the one that has achieved the highest score in the five criteriaconsidered in this regard because Meesia triquetra, a species with the category of “critically endangered”, inhabits it.

Ericaria zosteroides is a canopy-forming macroalga belonging to the order Fucales, which dominates Mediterranean deep-water stands. In the present research, populations of E. zosteroides from three locations (Santa Maria La Scala, Scalo Pennisi and Acque Fredde) along the central-eastern coast of Sicily (Italy, central Mediterranean) were monitored for five years (from 2017 to 2021). E. zosteroides from all locations in this area share a common phenology: recruits start to appear between January-February; then during spring the frond grows and becomes fertile; in summer it begins to thin out until the autumn when almost all branches have been lost; and finally at the beginning of winter, new primary branches start to grow from the tophules. Nonetheless, we detected a difference in the most frequent size class among the studied populations, being 9 cm at Santa Maria La Scala, 6 cm at Scalo Pennisi and 4 cm at Acque Fredde. This difference could be due to the current regime, related to the tidal currents of the Strait of Messina and upwelling currents of the Ionian Sea, and the coastal morphology which determines local variations in this regime, with multiple eddies characterised by marked directional instability. The low growth rate and dynamics of these stands make them very susceptible to recovery from anthropogenic impacts. Considering that E. zosteroides is a threatened species according to the Barcelona Convention, it would be crucial to ameliorate the conservation status of the investigated populations, which currently do not present any level of protection, in order to promote their future viability.
