“…For instance, in the Bobiri Forest Reserve, Ghana, a total of 27 species (≈18 species/ha) was recorded [17] whereas a much lower species richness (27 species ≈ 9 species/ha) was reported in the Tinte Bepo Forest Reserve, Ghana [15]. Moreover, liana species richness in this study was higher than those reported from outside Ghana: 51 species/ha in Bolivia [28] and 44 species/ha in China [29].…”

“…e absence of signi�cant relationship between liana abundance and canopy cover may be related to the ability of liana species in the forest to regenerate and grow well in shade and canopy gaps [39], leading to no clear cut pattern. Generally, the average level of liana infestation (48.8%) recorded in the Southern Scarp Forest Reserve was lower than what has been reported in other forests [2,17]. e level of liana infestation increased signi�cantly with disturbance intensity, showing that high levels of disturbance could be more favourable to liana colonisation.…”

“…Furthermore, liana species were clustered into three different groups, one in each forest type. ese patterns clearly demonstrated that liana species dominance responded differently to different disturbance intensities in the study area [17]. e equitability of distribution of IVI among liana species increased with disturbance intensity.…”

“…In the present study, liana density of 406 individuals/ha obtained was higher than what was reported in the Tinte Bepo and Bobiri forest reserves (253 individuals/ha and 213 individuals/ha, resp.) [15,17]. In the Democratic Republic of Congo, liana densities of 54 and 239 individuals/ha were recorded in a monodominant and mixed stands, respectively, in Ituri Forest [30].…”

“…Both patterns of increasing and decreasing liana diversity and structure have been reported in tropical forests, although majority of them have centered on the former [17]. ough human disturbance could have direct effects on liana communities through species removal, it could also cause changes in certain characteristics of the ecosystem such as forest structure and soil properties, which in turn, could in�uence liana community assembly.…”

e study was conducted to determine the factors that in�uenced liana species richness and structure in forests of different disturbance intensities (high, moderate, and low disturbance forests) in the Southern Scarp Forest Reserve, Ghana. Within each forest, lianas (dbh ≥ 2 cm) were enumerated in six 25 × 20 m 2 plots located along transects. Soil physicochemical properties and forest structure were determined within the plots. Liana species richness and abundance were signi�cantly lower in the high disturbance forest ( 0 00 ) whereas basal area was signi�cantly higher in the low disturbance forest ( 0 0 ). Tree abundance and dbh signi�cantly predicted liana species richness and structure in the study ( 0 05). On the basis of the importance value index, three main liana communities, each corresponding with a forest type, were identi�ed. Stepwise multiple regression analysis revealed that exchangeable magnesium and calcium, and total exchangeable bases were the main soil variables that affected liana species richness. Liana structure was in�uenced by the above-mentioned soil variables as well as exchangeable potassium and sodium, and pH. e present study has demonstrated that changes in liana species richness and structure following human disturbance may be due to variations in soil properties and forest structure.

Edge disturbance can drive liana community changes and alter liana-tree interaction networks, with ramifications for forest functioning. Understanding edge effects on liana community structure and liana-tree interactions is therefore essential for forest management and conservation. We evaluated the response patterns of liana community structure and liana-tree interaction structure to forest edge in two moist semideciduous forests in Ghana (Asenanyo and Suhuma Forest Reserves: AFR and SFR, respectively). Liana community structure and liana-tree interactions were assessed in 24 50 × 50 m randomly located plots in three forest sites (edge, interior and deepinterior) established at 0-50 m, 200 m and 400 m from edge. Edge effects positively and negatively influenced liana diversity in forest edges of AFR and SFR, respectively.There was a positive influence of edge disturbance on liana abundance in both forests.We observed anti-nested structure in all the liana-tree networks in AFR, while no nestedness was observed in the networks in SFR. The networks in both forests were less connected, and thus more modular and specialised than their null models. Many liana and tree species were specialised, with specialisation tending to be symmetrical.The plant species played different roles in relation to modularity. Most of the species acted as peripherals (specialists), with only a few species having structural importance to the networks. The latter species group consisted of connectors (generalists) and hubs (highly connected generalists). Some of the species showed consistency in their roles across the sites, while the roles of other species changed. Generally, liana species co-occurred randomly on tree species in all the forest sites, except edge site in AFR where lianas showed positive co-occurrence. Our findings deepen our understanding of the response of liana communities and liana-tree interactions to forest edge disturbance, which are useful for managing forest edge.

This book series provides complete, comprehensive and broad subject based reviews about existing biodiversity of different habitats and conservation strategies in the framework of different technologies, ecosystem diversity, and genetic diversity. The ways by which these resources are used with sustainable management and replenishment are also dealt with. The topics of interest include but are not restricted only to sustainable development of various ecosystems and conservation of hotspots, traditional methods and role of local people, threatened and endangered species, global climate change and effect on biodiversity, invasive species, impact of various activities on biodiversity, biodiversity conservation in sustaining livelihoods and reducing poverty, and technologies available and required. The books in this series will be useful to botanists, environmentalists, marine biologists, policy makers, conservationists, and NGOs working for environment protection.More information about this series at
