- Impacts of climate variables and seasonal water depth on emergent
macrophyte biomass production in King’wal riverine wetland, Kenya
Abstract: The production of macrophyte biomass holds a crucial role in supporting diverse life forms within wetland ecosystems. However, this biomass production is intricately tied to hydrology of the inland wetland system, which in turn is driven by the local climates seasonal patterns. The response of macrophyte biomass production to seasonal changes in water depth, influenced by rainfall patterns a...

- Effects of land use on floristic composition and diversity of woody
vegetation in the commune of Enampore, Senegal
Abstract: The diversity of woody vegetation is threatened by intensified land use and soil chemistry. However, the effects of land use and soil chemistry on woody vegetation are not well known. The objective of this study was to determine the influence of land use classes (upland, uncultivated lowland, cultivated lowland, and tans) on the diversity and structure of woody vegetation in the commune of E...

- Effect of IAA on spore germination and gametophyte development in
Ceratopteris thalictroides (l.) brongn. from Sitamata Wild Life Sanctuary,
Rajasthan
Abstract: The effect of different concentrations of Indole acetic acid (IAA) on spore germination and gametophyte development of Ceratopteris thalictroides, a leptosporangiate fern of the family Pteridaceae found at the marshy places near Sitamata sanctuary in Rajasthan, was observed. The highest spore germination percentage was recorded in the 2 to 6 ppm concentration range of IAA, with minimum in th...

- Diversity and composition of the epiphytic flora in an urban
agglomeration: The case of city of Douala, Cameroon
Abstract: Epiphytes constitute an element of climate regulation in the tropical zone. In Cameroon, the decline in forest area of about 220,000 ha, partly due to urbanization, has been observed. The research aim was to characterize the epiphytic flora of the urban ecosystem of Douala. Four zones represented by nine neighbourhoods were chosen for the surveys. Four transects of a maximum distance of 500 ...

- Photophysiology, dark respiration and leaf desiccation resilience of the
fern Adiantum capillus-veneris L.
Abstract: Adiantum capillus-veneris is a cosmopolitan, globally distributed terrestrial fern in warm temperate to tropical regions. It is also widely cultivated in indoor and outdoor settings. The natural habitat of A. capillus-veneris includes limestone rocky places with consistent sources of water, including shady alkaline, moist cliffs and on vertical surfaces in moist forested locations, preferabl...

- Assessment of carbon sequestration by mangrove plantations in Casamance
(Oussouye, Ziguinchor, Senegal)
Abstract: The mangrove ecosystem abounds in fish and wood resources exploited by local populations for cooking and house construction. This has resulted in a strong loss of mangrove surfaces whose causes are explained by the combined action of natural and anthropic factors. To minimize the regression of the mangrove in Casamance, the Oceanium Association has organized since 2006 reforestation campaign...

- Effect of heavy metals and physicochemical parameters on diversity of
plants at a gold mine tailings dam in Ghana
Abstract: This study focuses on the impact of physicochemical parameters and heavy metals concentrations in soil on abundance, richness and diversity of plants at Marlu tailings dam located near Bogoso, Ghana. The concentrations of heavy metals (mg/kg) in soil at the study area are as follows: Fe (10,528.9 - 7,873.0), Cu (224.9 - 177.4), Zn (51.6 - 42.7), Cd (3.0 - 2.6), As (2.4 - 1.7) and Mn (78.3 - ...

- Pare’s people perception influences on conservation of wild plant
diversity in protected areas in Kilimanjaro Region, Northern Tanzania
Abstract: This study was designed to assess Pare peoples perception about the role of protected areas in biodiversity conservation. Viewpoints on factors causing biodiversity loss, related consequences and peoples participation in forest husbandry activities were also investigated. Data were collected from Same and Mwanga Districts using semi structured interview. Results indicated generally that majo...

- Aquatic macro invertebrate contribution in leaf litter breakdown in
tropical mining area streams (Côte d’Ivoire, West Africa)
Abstract: The aim of the study was to determine how mining operations affected the health of aquatic ecosystems. The investigation was carried out in the diamond, gold, and manganese mining areas of Tortiya, Hir, and Lauzoua. Leaf litter bags were used to assess breakdown. To further identify macro-invertebrates in the laboratory, leaves from emerged large-mesh bags were preserved in 70% alcohol. The ...

- Floristic diversity and regeneration of wild edible fruit species in the
Reserve of Moutourwa and its surroundings (Far-North Cameroon)
Abstract: In order to assess the diversity, regeneration and structure of wild edible fruit trees, a study was carried out in the Laf-Madjam forest reserve and its surroundings. A semi-structured interview with local residents and a floristic inventory of woody plants (8 transects of 1000 m 20 m each) were carried out. 24 species were cited as being used by the local residents. A total of 2134 indivi...
