Plant-animal mutualisms are characterized by weak or asymmetric mutual dependences between interacting species, a feature that could increase community stability. If invasive species integrate into mutualistic webs, they may alter web structure, with consequences for species persistence. However, the effect of alien mutualists on the architecture of plant-pollinator webs remains largely unexplo...

Invasive alien plants (IAPs) are responsible for loss in biodiversity and the depletion of water resources natural ecosystems. Prosopis species IAPs previously introduced by farmers to provide shade fodder livestock. In Northern Cape, spp. invasions associated with native resulting overgrazing degrading rangelands. Mapping glandulosa is essential management initiatives assist government minimis...

Introduction This account provides a brief overview of alien plant invasions in South Africa, with special emphasis on what is known about their consequences, including those affecting the delivery of ecosystem goods and services. We draw on published and unpublished sources, and highlight some important research challenges in invasion ecology that need to be met if we are to address critical g...

Abstract Invasive alien plants (IAPs) are a significant threat to the biodiversity and ecological functioning of sub-Antarctic Prince Edward Islands (PEIs); however, weed biological control has not yet been implemented as management tool. The PEIs have had 23 recorded, which several considered beyond eradication therefore could benefit from release safe effective biocontrol agents. We used Sout...

Global biodiversity is not uniformly distributed in terms of species richness. The global and national protected areas (PAs), the Indian Himalayan Region (IHR) North East (NE) India, are extremely rich plant biodiversity, contributing to environment socio-economy/livelihood prospects, linked with human health or well-being. However, anthropogenic disturbances have modified vegetation structure ...

At local scales, it has often been found that invasibility decreases with increasing resident plant diversity. However, whether resident community diversity similarly resists invasion by alien versus native species is seldom studied. We examined this issue by invading constructed native plant assemblages that varied in species and functional richness with invasive alien or native Asteraceae spe...

more than 32 alien (exotic) fish species belonging to 10 orders and 12 families (cyprinidae, gobiidae, salmonidae, anguilidae, mugilidae, centrarchidae, heteropneustidae, gasterosteidae, cichlidae, poecilidae, adrianichthyidae and pleuronectidae) were reported from iran of which 25 species are confirmed by specimens. some of the alien fishes (e.g., cyprinus carpio , carassius auratus , pesudora...

Our understanding of the interrelated mechanisms driving plant invasions, such as the interplay between enemy release and resource-acquisition traits, is biased by an aboveground perspective. To address this bias, I hypothesize that plant release from belowground enemies (especially fungal pathogens) will give invasive plant species a fitness advantage in the alien range, via shifts in root tra...

This study examined the knowledge of Collaborative Adaptive Stewardship (CASt) to advance Invasive Alien Plants (IAPs) management in South Africa. concept promotes involvement private landowners and other stakeholders action processes, hence promoting social inclusivity, job creation, sustainable biodiversity stewardship. It demonstrates that are major IAPs management, thereby practising stewar...
