An invasive grass species has both local and broad-scale impacts on diversity: Potential mechanisms and implications
<p>Questions</p> <p>The impact of invasive plant species on native diversity varies with spatial scale, with some invaders leading to broad-scale diversity declines and others only local declines. These discrepancies may reflect the invaders capacity to reduce niche opportunities across spatial scales which can be associated with their functional traits. We investigated impact-scale relationships and trait-based mechanisms, in areas invaded by the exotic perennial grass species, <i>Bothriochloa pertusa</i>. We examine root traits specifically, as belowground competition was considered particularly important to the success of this species.</p> <p>Location</p> <p>Grassy 'ironbark' woodlands of eastern Queensland, Australia</p> <p>Methods</p> <p>We examined plots with varying degrees of invasion by <i>B. pertusa,</i> at multiple spatial scales (up to 1000 m<sup>2</sup>) and analysed changes to the species area relationships (SARs) with increasing invader cover. Changes to SARs were assessed in relation to the invaders effect on rare (low-patch-occupancy) and common species in the community. In a separate analysis within the same habitat we collected root cores across a gradient of invader cover and analysed changes to community root traits that were considered important correlates of competition for space and nutrients.</p> <p>Results</p> <p>Invasion-induced reductions in diversity were pervasive at all scales investigated, and this was associated with a proportionally greater effect on rare species in the community. In the separate root analysis, changes in community root traits with increasing invader cover were potentially indicative of more intense competition for resources rather than space.</p> <p>Conclusions</p> <p>The observed regional-scale dominance of <i>B. pertusa</i> and associated declines in diversity warrant serious concern for the conservation of native plant communities and species in a region already at risk from other anthropogenic threats. Intense competition for belowground resources is likely a contributing mechanism to the success of <i>B. pertusa</i> in this study system. Experimental examination of this and other mechanisms would help to validate these findings.</p>
Data from: Forest degradation and invasive species synergistically impact Mimusops andongensis (Sapotaceae) in Lama Forest Reserve, Benin
Harvesting of Non-Timber Forest Products (NTFPs) can threaten target species, especially those with limited distribution and density. Exploited species also face threats from habitat fragmentation, fire, and invasive species. We assessed the impact of human disturbances and invasive species on the population of a key multipurpose NTFP species, Mimusops andongensis, in Lama Forest reserve (Benin). The densities of adult trees and regenerative stems decreased with increasing degradation. Mimusops andongensis contributed less to total tree density with increasing human disturbance. There were significantly fewer M. andongensis recruits with increasing cover of invasive Chromolaena odorata. Smaller diameter individuals predominated in non-degraded and moderately degraded sites while in degraded sites, the structure showed a negative exponential trend with the density of small diameter individuals being less than two trees/ha. Larger individuals were also rare in degraded sites. The low density of both mature trees and seedlings in degraded sites may undermine the long-term viability of M. andongensis, despite existing protection against NTFP harvesting and other anthropogenic pressures. Management should emphasize facilitating recruitment subsidies and limiting the presence of C. odorata.

Impact of Invasive Species & Ecosystem-Based Fisheries Management
<p>During the Sabai Webinar Series 14, hosted by the Shwetaungthagathu Reform Initiative Centre (SRIc), Burmese Experts, including Mr Phoe Cho, Fisheries Specialist, Mr Thadoe Wai, Local Freshwater Ecologist and Mr Tin Shine Aung: Sustainability Consultant and Researcher engaged in a discussion on <br>ecological impact of invasive fish species in Myanmar. </p> <p>They highlighted the consequences of introducing invasive fish species into natural water sources, such as rivers, streams, & seas and why ecosystem-based fisheries management is important. </p> <p>This Sabai Webinar Series was conducted under the Edu4SD project.</p> <p> </p>

Fig. 2. Number of exotic records of Pterygoplichthys spp. by year recorded in the literature. Records with missing dates were treated using the publication date and the single record of "late 1950s" was treated as 1960. A total of 71 records of exotic Pterygoplichthys spp., either individuals or populations, were reported through October, 2017; 55 of these records represented established populations.

Fig. 1. Global distribution of nonnative Pterygoplichthys spp. represented with filled-in geopolitical polygons for established populations, filled-in circles for potentially isolated detections, and a circle with a red X over it for the single eradication. Each species is represented by a different color. Geopolitical areas with multiple established species are displayed with a multicolor pattern using the relevant species' colors. The Gulf Coast/Caribbean region and central Indo-Pacific region are represented in higher resolution map insets with red and yellow borders, respectively. Color-filled polygons (e.g. states) indicate establishment in, but not necessarily throughout, an area.
