A flora treatment of the family of Cannaceae in the Democratic Republic of the Congo, Rwanda and Burundi is given. The family is represented by a single genus, Canna. The only species present in Central Africa has been introduced as an ornamental from tropical America, and regularly escapes.

We investigated the land-snail fauna in gallery forest sites along a 30-km long section of the Muvumba River in northeastern Rwanda. A total of 12,419 individuals assigned to 34 land-snail species were collected in 24 plots. Though the number of species is small compared with protected rainforests...

Wetland maps are a prerequisite for wetland development planning, protection, and restoration. The present study aimed at mapping and monitoring Rwanda's Akagera Complex Wetland by means of remote sensing and geographic information systems (GIS). Landsat data, spanning from 1987 to 2015, were...

Risk-assessment methods are useful in collecting data that can help decision making to prevent the introduction of new species that have the potential of invading as well as in management of established taxa. Not only the complexity and unaffordability of available pre-introduction risk-assessment...

Based on empirical evidence from a vegetation survey, this paper investigates the occurrence of self-established populations of black wattle (Acacia mearnsii De Wild.) in various environmental contexts and identifies areas where this species could be allowed to grow as a useful plant. The frequency ...

Invasive species pose a serious threat to the conservation of biodiversity. Forestry is the most important driver of the introduction and spread of invasive woody plant species after horticulture. Nearly 450 invasive tree species have been recorded worldwide, amounting to more than half the world's ...

A flora treatment for the Plumbaginaceae occurring in the Democratic Republic of the Congo, Rwanda and Burundi is provided. The family is represented by two genera, one of which is introduced, and 5 species, two of which are cultivated as ornamentals and may occasionally escape. The species ...

A flora treatment for the Bromeliaceae occurring in the Democratic Republic of the Congo, Rwanda and Burundi is given. The family is native to South America, but is represented here by the widely cultivates species Ananas comosus.

The introduced shrub flora in Rwanda was analyzed and the risk of invasion was assessed based on the species' purposes of introduction. The results showed that more than half of invasive alien shrubs in Rwanda were introduced as ornamentals. They include Agave americana L., Bryophyllum proliferum...

The sensitivity of photosynthetic metabolism to temperature has been identified as a key uncertainty for projecting the magnitude of the terrestrial feedback on future climate change. While temperature responses of photosynthetic capacities have been comparatively well investigated in temperate...
