“…In Hungary, the south-facing slopes receive much more solar radiation than the north-facing ones, therefore the south-facing doline parts are warmer than the opposite ones (Jakucs 1971). Our results are in good agreement with the findings of other authors who found significant differences between the vegetation characteristics of north-facing and south-facing slopes in several environments (Hutchins et al 1976;Armesto & Martínez, 1978;Hicks & Frank 1984;Kutiel & Lavee 1999;Erdős et al 2012). The strong increase in species richness within the wet group along the north-facing slope of the non-forested doline can probably be explained by steep nighttime temperature gradients.…”

The present study compares the vegetation characteristics of two large forested and one large non-forested solution dolines in Hungary. We investigated the species composition and vegetation pattern along north to south transects (across the doline bottoms) and compared the richness of different species groups (dry and wet groups) on the doline slopes. We applied linear regression models for each slope to explore the effects of topography on species richness, and Detrended Correspondence Analysis (DCA) to detect the major gradients of floristic variation within each site. We found that the vegetation changed significantly along all transects; and, regardless of the vegetation cover, the doline bottoms contained several cool-adapted species. Variations within the two species groups were more pronounced on the south-facing slopes. The changes were similar in the forested dolines, indicating the role of forest cover in maintaining many cool-adapted species on the north-facing slopes as well. However, the number of cool-adapted species increased significantly along both slopes of the non-forested doline from the upper edge to the bottom. Contrary to our expectations, the species turnover along the slopes of the non-forested doline was lower than that along the slopes of the forested ones. We conclude that both the forested and non-forested dolines serve as refuges for many plant species adapted to different environmental conditions. Apart from providing an understanding of population patterns along environmental gradients, our results may also contribute to our understanding of an even more fundamental question for a future research agenda: the probable effects of climate change on vegetation characteristics in climatic islands with environmental conditions substantially different from the surrounding areas.

“…In addition, the highest carbon stock was found in the western aspect in Tara Gedam forest of Ethiopia [30] and the lowest carbon stock found on north eastern aspect in woody plants of Arba Minch ground water forest of Ethiopia [31] were in excellent agreement to the present study. This is possibly due to the availability of moisture and fertile soil in the western part and less moisture and fertility in north-eastern part of Banja forest as noted by Hicks and Frank [28] that soil properties are influenced by aspect.…”

This study was conducted in Boswellia dominated woodland at Kafta Humera to estimate the amount of carbon stored in different age of exclosures and along different aspects. Ages of exclosures (eight, four, two and zero year) were used, and the aspects were classified in to east, west, north and south aspects. One hundred twenty eight (128) sampling quadrants having an area of 20 m × 20 m, were systematically laid using four transect lines at different distance. The aboveground carbon was analyzed using two-way analysis of variance. A total of twenty one (21) woody spices belongs to thirteen (13) families were identified and documented. There were significantly different (P<0.05) among age of exclosures. Eight-year exclosure was significantly higher in aboveground biomass (88.57 Mg/ha) and aboveground carbon (41.63 Mg/ha) followed by four, two and zero years of exclosure. Despite no significant differences (P<0.05) was seen between aspect for aboveground biomass and carbon. It had the order of west>east>south>north aspects. The results confirmed that exclosures plays a major role in the conservation of native woody species. However, more afforestation and reforestation are needed for better carbon storage in all exclosures.

“…Vegetation abundance and canopy are significantly related to spatial nutrient distribution, slope aspects and plant diversity. Studies have been conducted and dedicated to the aspects of temperature, soil moisture availability and tree growth, such studies includes [2], [3] and [4]. However, slope aspects are also considered important factor in distribution of ground-flora species [5], [6].…”

Spatial nutrients that includes OM, Avail.K, Avail.P and TN distribution and the influences on vegetation patterns in Dalingshan was the cardinal focus of this study. Ecological data (moisture content, bulk density and topography) were considered. One way ANOVA was statistically tested of spatial distribution of major nutrients across 4 plots which indicated non significant at p = 0.05 level, TN (p = 0.0216), OM (p = 0.00004), Avail.K (p = 0.00216) respectively. Furthermore one way ANOVA was tested on acidity level (pH) measured against the nutrients distribution TN (p = 0.0031), OM (p = 0.0004), Avail.K (p = 0.0216) respectively at non significance level but available phosphorous was significantly different (p = 0.6412). The study revealed unique spatial patterns of soil nutrient distribution in Dalingshan and species abundance while vegetation census posed a new direction of study that may be adapted for a broad range of regional vegetation and floristic modeling. This paper suggests that forest soil nutrients and vegetation interaction can be utilized for further studies on multifactor ecosystem responses towards regional ecological restoration.
