The Study of Exotic and Invasive Plant Species in Gullele Botanic Garden, Addis Ababa, Ethiopia

Journal of Zoological and Botanical Gardens
The Gullele Botanic Garden was established to preserve and safeguard indigenous, rare, endemic, endangered, and economically important plant species. The objective of this study was to identify and map the exotic, invasive, and potentially invasive plant

Design and Validation of a Single‐Species Environmental DNA qPCR Assay for the Detection of the Invasive Chinese Mitten Crab Eriocheir sinensis

Environmental DNA
Biological invasions are a leading driver of biodiversity loss and generate significant economic costs, either through direct impact on native ecosystems or through repairs and remediation.

The longitudinal gradient prevails over local characteristics in shaping fish species distributions in a large neotropical reservoir

Water Biology and Security
In large reservoirs, spatial gradients are the primary drivers of fish species distributions. However, local characteristics can also influence fish distributions and assemblage structure.

Thresholds for sustainable regeneration in urban restoration plantings in Hamilton City, New Zealand

, 2014
Urban forest patches have unique environmental and landscape characteristics which may influence the restoration of native plant communities. Urbanisation can lead to a drier and warmer climate, a prevalence of exotic seed sources and isolation from ...

Impact of broom, Cytisus scoparius (Fabaceae), in naturally treeless sub-alpine frost-hollow vegetation communities at the Barrington Tops, south-eastern Australia

, 2013
The exotic shrub Cytisus scoparius (L.) Link (family Fabaceae), known as broom, is having a major impact on native vegetation in naturally treeless sub-alpine frost-hollow areas (c. 32o 01’ 37” S, 151o 26’ 12” E’, 1440 m elevation) at the Barrington Tops,

Characteristics of exotic ants in North America

, 2011
The worldwide transport of species beyond their native range is an increasing problem, e.g. for global biodiversity. Many introduced species are able to establish in new environments and some even become invasive.

Vegetation recovery and management of kahikatea (Dacrycarpus dacrydioides)-dominated forest remnants in the Waikato Region

, 2010
The principle aim of this study was to determine whether fencing alone is a sufficient management tool for facilitating the recovery and persistence of indigenous flora in kahikatea-dominated forest patches in the Waikato region.

The Natural Ambiguity of Native Species

UnderCurrents: Journal of Critical Environmental Studies, 2004
Mainstream ecological wisdom suggests that native species are essential to the preservation and promotion of ecological health or integrity: they are often deemed to be the ‘natural’, ‘authentic’ and ‘original’ occupants of particular habitats. Philosophically and pragmatically, they are generally considered crucial to biodiversity at scales ranging ...
