“…In reality, 74% of nests were found in Oued al Jawahir, compared with 24% of nests in Mahraz dam, while in El Gaada no nest was found. This nest abundance in the river might due to the richness of Oued Fez in vegetation and food availability as noted by Perrin et al (2014) and Khabbach et al (2019). On the other hand, the wide surface and long-distance of Oued al Jawahir River could offer a variety of habitats and location to the Eurasian coot to build a save nests (Olsen et al 2006;Leslie 2001).…”

The current study was intended to investigate the breeding habitats and ecology of the Eurasian coot Fulica atra in Fez region Morocco. To achieve our goals, nests were monitored in three wetlands Oued Al Jawahir river, Mahraz and El Gaada dams. In addition, nesting vegetation and nest's dimensions were analysed to characterise the Eurasian coot nests. As results, 46 nests (74%) were found in Oued al Jawahir, compared with 15 nests (24%) in Mahraz dam. In El Gaada dam only 2 nests were built by the Eurasian coots. On the other hand, all nests were built on the riparian vegetation of the river and dams. Besides, nests were located in the periphery of the river stream. Many plants were used entirely or special parts, such as stems and roots in nesting activity. Typha angustifolia is used in 45.3% of nests and J. acutus in 38.6% of nests. Other plants are found with a minor presentation in nests, including P. stratiotes (9.6 %) of nests, Phragmites australis (5.6%), and Tamaris sp. (0.9%). These plants form the structure of nests and support. Besides nesting in river's periphery, the nests were constructed at an average height of 14.5 ± 0.05 away from the stream of water. Concerning nest success, nest predation ranged from 57% (2018) to 60% (2019). Nests were lost due to water stream and human disturbance. Finally, Eurasian coots build its nests in the periphery of water ecosystems and in an important high to avoid flooding periods and human disturbances.

Honey with Bupleurum spinosum (zandaz) as a main pollen source has not been the subject of previous detailed study. Therefore, twelve Moroccan samples of this honey were subjected to melissopalynological, physicochemical and microbiological quality characterization, as well as antioxidant activity assessment. From a quality point of view, almost all samples were within the limits established by Codex Alimentarius, and/or the European legislation. All samples presented predominance of B. spinosum pollen (more than 48%). Relatively high levels of trehalose (1.3-4.0 g/100 g) and melezitose (1.5-2.8 g/100 g) were detected. Those sugars, not common in monofloral honeys, could be used as an important factor to discriminate zandaz honey. Flavonoid content correlated positively with the honey color, melanoidin and polyphenol content, and negatively with the IC 50 values of scavenging ABTS (2,2´-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) free radicals, while proline amount correlated negatively with IC 50 values of nitric oxide scavenging activity and chelating power. This correlation supports the use of anti-oxidant activities as important variables for PCA (principal component analysis). Both components explained 70% from the given data, and showed certain homogeneity upon analyzed samples independent of the region, suggesting the importance of B. spinosum nectar in the resulting honey characteristics. Caracterizació n preliminar de una miel marroquí con predominio del polen de Bupleurum spinosum La miel con Bupleurum spinosum (pendejo) como principal fuente de polen no ha sido objeto de un estudio detallado previo. Por lo tanto, doce muestras marroquíes de esta miel fueron sometidas a una caracterizació n melisopalinoló gica, físico-química y microbioló gica, así como a la evaluació n de su actividad antioxidante. Desde el punto de vista de la calidad, casi todas las muestras estaban dentro de los límites establecidos por el Codex Alimentarius y/o la legislació n europea. Todas las muestras presentaron predominio de polen de B. spinosum (más del 48%). Se detectaron niveles relativamente altos de trehalosa (1.3-4.0 g/100 g) y melecitosa (1.5-2.8 g/100 g). Esos azúcares, no comunes en mieles monoflorales, podrían ser utilizados como un factor importante para discriminar la miel de pendejo. El contenido de flavonoides se correlacionó positivamente con el color de la miel, el contenido de melanoidina y polifenol y negativamente con los valores de IC 50 de la actividad de barrido de los radicales libres de ABTS (2,2'-azino-bis (3-etilbenzotiazolina-6-sulfó nico), mientras que la cantidad de prolina se correlacionó negativamente con los valores de IC 50 de la actividad de barrido de ON (ó xido nítrico) y el poder quelante. Esta correlació n apoya el uso de las actividades antioxidantes como variables importantes para el APC (análisis de componentes principales). Ambos componentes explican el 70% de los datos obtenidos y muestran cierta homogeneidad en las muestras analizadas independientemente de la regió n, lo que su...

“…This is displayed in Morocco among others by 32.4% of ST with eutrophic habitat, and 13.9% mesohalophilic to halophilic taxa among ST and FT. Moreover, 3.85% of FT and 2.96% of ST have been introduced and/or naturalized, some of which already present a risk of invasion to local wetlands (Ennabili and Gharnit 2003a, b;Khabbach et al 2019Khabbach et al , 2020Libiad et al 2021). Aquatic invasive species can cause a wide range of ecological impacts, including the loss of native biodiversity.…”

Importance of Wetlands in Maintaining the Richness of Morocco’s Vascular Flora

Morocco's wetlands are renowned much more for their abundance and diversity than for their extent. The vascular flora of wetlands is not properly considered in national programs for the conservation and protection of biodiversity, although the first work concerning it dates back about half a century. This work highlights the overall richness of wetlands in terms of vascular plants. Indeed, around 36% of the Moroccan vascular flora exist in wetlands as specific (ST), facultative (FT) or opportunistic (OT) taxa. This taxonomic richness of wetlands, notable in North Atlantic Morocco and the Rif, depends more on local conditions than on bio-geographical zoning. The various factors that threaten this richness of vascular flora are emphasized in the context of disturbing wetland habitats and alarming global warming, i.e. unreliable database of local wetland biodiversity, inefficiency of development programs and actions that have been attempted, and non-comprehensive decision-making. It is particularly expected that Morocco's commitment to the conservation of global biodiversity will lead to the development of a sustainable policy to conserve local wetlands.
