“…However, fire has also been attributed to long-term increases in bacterial and fungal biomass and diversity 2–3 years after a wildfire ( Rodriguez et al., 2018 ). At even greater scales, fire has been attributed to the decrease in bacterial and fungal biomass after 14 years ( Allam et al., 2020 ). This confirms that the resilient soil microbial population and diversity were able to adapt to the new environmental conditions caused by the wildfire.…”

IntroductionFire and nitrogen (N) deposition each impact biodiversity and ecosystem productivity. However, the effect of N deposition on ecosystem recovery after fire is still far from understood, especially in coastal wetlands.MethodsWe selected a typical coastal shrubland to simulate three N deposition levels (0, 10, and 20 g N m−2 year−1) under two different burned conditions (unburned and burned) in the Yellow River Delta of North China. Soil properties, soil microbial biodiversity, shrub growth parameters, herbaceous biodiversity, and aboveground productivity were determined after experimental treatments for 1 year.ResultsWe found that fire had a stronger influence on the ecosystem than N addition. One year after the fire, shrub growth had significantly decreased, while soil pH, soil electrical conductivity, herbaceous biodiversity, soil microbial biodiversity, and herbaceous aboveground productivity significantly increased. Conversely, a single year of N addition only slightly increased herbaceous aboveground productivity. The combined effect of fire and N addition was only significant for fungus biodiversity and otherwise had minimal influence. Interestingly, we found that herbaceous aboveground productivity was positively associated with fungal community diversity under unburned conditions but not in burned shrublands. Fire showed a great impact on soil parameters and biodiversity in the coastal wetland ecosystem even after a full year of recovery.DiscussionFire may also diminish the influence of several belowground factors on herbaceous aboveground productivity, which ultimately reduces recovery and stability. Appropriate N addition may be an effective way to improve the ecosystem productivity in a wetland dominated by shrub species.

“…During the dry season, intense grazing is responsible for changing the structure and composition of the vegetation. In the long term (Allam et al, 2019), it can cause a reduction in revegetation speed after the first rains following a drought (Kinloch and Friedel, 2005;Metzger, 2005). Seasonal drought seems to affect floristic wealth more than animal activity.…”

This work is devoted for the floral richness and seasonality evaluation of the plant communities of the Tessala Mountains in Western Algeria. The floristic inventory of the 30 surveys carried out on 10 selected stations has resulted in 152 species under 125 genera and 48 families. Seasonal floral richness is concentrated in both spring and summer seasons, while the monthly richness is significant between Marchto August. Vegetations formations are represented physiognomically by four strata, taken into consideration in descending order of importance: Herbaceous (68%), shrubby (12%), arbustive (11%), and arborescent (10%). The overall and seasonal distributions of biological types almost follow the diagrams: Therophytes (The)> Hemicryptophytes (Hem)> Phanerophytes(Pha) > Chamephytes (Cha)> Geophytes (Geo). During the two season: the winter and the spring, the annual herbaceous dominate the bio-morphological spectrum with perennial herbs. During the summer and autumn, perennial herbaceous plants dominate the bio-morphological spectrum. The families that are mostexisting overall and during the four seasons are Asteraceae, Poaceae, Lamiaceae and Fabaceae. Bangladesh J. Plant Taxon. 30(2): 233-248, 2023 (December)

“…Most forest environments worldwide have suffered significant losses in their floristic composition (Cardoso et al, 2013). Increasing population numbers and human activities are impacting forests (Allam et al, 2020) and changing globally the landscape through afforestation and deforestation (Zhou et al, 2018). The acceleration of the fragmentation and degradation of these fragile ecological environments 4…”

The development of agriculture to the detriment of the forest is one of the strongest pressures, essentially anthropogenic. The particularity of this study was that the traditional agricultural practice used was low intensity agriculture (fallow period) since the first conversion. The experiment was conducted in the Keroua forest, Saïda Province, north-western Algeria. Soil samples from two experimental areas were collected at depths ranging from 0 to 10 cm. The findings came from the statistical analysis of the data, some of which revealed the sensitivity of this ecosystem. The conversion of the forest soil to agricultural land increased the alkalinity of the soil (pH H2O increased by 0.16 units), and the acidification of the soil with a significant decrease in pH KCl values (by 0.24 units). Moreover, the organic matter content in the converted soil decreased by more than 50%, while the physical characteristics changed slightly with a decrease in moisture content and water holding capacity and an increase in bulk and real density. Meanwhile, the permeability and total porosity did not change in the two areas. For biological properties, basal respiration and microbial biomass decreased by more than 45% in the converted soil compared to the forest soil.
