“…García, (2016) studying "bird-plant" networks, came to the conclusion that they are sensitive to anthropogenic impacts, especially habitat degradation, biodiversity reduction, and biological invasions. Conversely, zoochory can promote the germination of invasive organisms (de Freitas et al, 2020). In food webs, it is also important to coincide the phenodates of the birds' presence during the period of certain plants' fruit ripening and the anatomical correspondence of the bird's pharynx to the size of the fruit of a plant.…”

Parthenocissus inserta (A. Kern.) Fritsch. adapts to living in the forests of Ukraine. The influence of P. inserta on native species and its consortial ties with representatives of the secondary ranges biota, in particular birds, has not been studied. The purpose of this study is to make an inventory of the consorts’ ornithocomplexes of P. inserta, to give a comparative analysis of topic and trophic consorts as a result of an introduced species’ participation in the transformation of habitat’s conditions. The material was collected from 2019 to 2022 in forest parks and urban green spaces of the Kyiv city. The bird distribution was determined by the standard method of counting birds at points. Exactly 12.2 ha of P. inserta plantations were surveyed. Trophic consortium relationships of P. inserta with 32 bird species and topic ones with six bird species were revealed. The species composition of consorts was higher in forest fragments than in urban plantations (26 and 21 species, respectively). In the ornithocomplexes of P. inserta consorts in forest biotopes, there was a smaller pressure of dominant species and a more evenly ranked distribution of species by abundance than in urbanized ones. The similarity of the consort’s species composition in urbanized and natural biotopes according to the Sorensen index was 0.64, in consorts 1 and 2 of the consortium concentres was 0.32, and in topic and trophic consorts was 0.27. According to the status of stay in the region, trophic consorts of P. inserta were mainly resident birds – 20 species (62.50%), wintering birds – six species (18.75%), and birds migrating through the region – six species of birds (18.75%). Among the topic consorts, there were four species of sedentary species and two species arriving for nesting. Principal component analysis revealed the largest positive relationship between P. inserta planting area and the number of consort bird species nesting (0.999) and feeding (0.889) on girlish vine plants. We predict that in the future, P. inserta will be more strongly woven into the matter cycle of the secondary range ecosystems. The study of consortial relationships between invasive plants and birds, taking into account the knowledge of the ecological characteristics of consort birds, will make it possible to more effectively prevent the spread of plants into natural biotopes.

“…The USA is the world’s foremost producer of and market for nursery and floriculture plants ( Niemiera and Von Holle 2009 ), particularly in the post-World War II economic boom which increased demand for commercial shipping of ornamental plants ( Reichard and White 2001 ). Schinus terebinthifolia was first recorded in 1919 in South Africa ( Potts 1919 ) and this is around the same time of introductions of the plant into Hawaii ( de Freitas et al 2020 ). These introductions to both Hawaii and South Africa would have occurred before plants in Florida became admixed through hybridization of the two haplotypes ( Williams et al 2007 ; Mukherjee et al 2012 ).…”

Uncovering the phylogeography of Schinus terebinthifolia in South Africa to guide biological control

Schinus terebinthifolia is a problematic invasive alien plant (IAP) in South Africa that is a high priority target for biological control. Biological control has been implemented in the states of Florida and Hawaii (USA), where S. terebinthifolia is also an IAP. Phylogeographic work determined that there have been multiple introductions of two lineages (haplotype A and B) into the USA. Haplotype A was introduced to western Florida and Hawaii, while haplotype B was introduced to eastern Florida. Haplotypes A and B have subsequently hybridised in Florida, resulting in novel plant genotypes. Biological control agents in the USA are known to vary in efficacies on the two different haplotypes and hybrids. This study used molecular techniques to uncover the source populations of S. terebinthifolia in South Africa using cpDNA and microsatellites. Populations from the introduced ranges in Florida (east, west and hybrids) and Hawaii were included (n = 95). All South Africa populations (n = 51) were found to be haplotype A. Microsatellite analysis determined shared alleles with western Florida and Hawaiian populations. The likely source of South African S. terebinthifolia was determined to be western Florida through the horticultural trade. These results will help guide a biological control programme to source agents that perform well on these populations in the USA. Furthermore, the presence of only one haplotype in South Africa highlights the need to ensure no further introductions of other haplotypes of the plant are made, in order to avoid similar hybridisation events like those recorded in Florida.

“…This expressive bioinvasion is reflected in the reproduction ability of the species with about 20 and 40 seeds per fruit (Goodland and Healey, 1996) and with a long fructification period, mainly in periods of scarcity of other fruit resources (the seeds were recorded across 8 consecutive months, March to October, in the artificial perches). Pitangus sulphuratus, an abundant and generalist bird species found in the region, is an important agent in the dispersion and invasion of Pittosporum undulatum, having a positive effect on the germination of this species after the defecation (Freitas et al, 2020). In addition, the genus Turdus is considered another disperser of Pittosporum undulatum in the Atlantic Forest (Campagnoli et al, 2016).…”

“…Several authors have already addressed the relationship between frugivory and seed dispersal of invasive alien species (Jordaan and Downs, 2012;Campagnoli et al, 2016;Ortega-Flores et al, 2018). The results have shown that the ingestion of seed species by birds improves the seed species' rate of ger-mination (Freitas et al, 2020). This can promote the establishment of invasive plants that can interfere with and alter ecological processes, such as creating changes in nutrient cycling, biomass decomposition rates, plant community structure, pollination, seed dispersal, the aesthetic value of the landscape, and biodiversity loss due to species extinction (Ziller, 2001;Lourenço et al, 2011;Pyšek et al, 2020).…”

Abstract. One of the main barriers to restoration is the arrival of diaspores in degraded areas. However, this process can be hampered in open areas without trees in the landscape. For that, artificial perches are used to attract and provide a landing area for avian seed dispersers, to enhance seed rain. Our objective was to evaluate the effect of the distance of artificial perches in relation to a forest fragment on the diversity and composition of seed rain in an agricultural fallow area, including alien invasive plant species. We also aimed to record and characterize the bird species that potentially act as seed dispersers. Thus, we used artificial perches at three different distances from a forest fragment (5, 25, and 50 m). Four seed traps were arranged under the perches at each distance, and four control seed traps were interspersed with these and distanced at 7.5 m. Furthermore, we placed four seed traps inside the forest fragment at 5 m from the edge. We also carried out 80 h of focal observation of the avifauna that used artificial perches. A total of 24 655 seeds were sampled across all treatments. There was a significant difference in seed abundance and richness between artificial perches, control seed traps, and forest seed traps. Seed deposition increased with distance from the forest fragment (50, 25, and 5 m). An ordination procedure indicated the formation of three plant seed communities, with the forest community being most distinct. The invasive exotic species Pittosporum undulatum (Australian cheesewood) was the third most abundant in the seed rain. We observed 24 bird species from 12 families using artificial perches. The Tyrannidae family was the most represented. We showed that artificial perches are efficient structures for attracting birds, increasing the richness and abundance of seed species. Artificial perches at 25 and 50 m were more efficient possibly due to the provision of greater visibility for birds. Therefore, artificial perches are efficient in increasing seed rain in the fallow area but should be used with caution in landscapes with the presence of alien species. These findings contribute to increasing knowledge about overcoming the first barrier to ecological restoration, which is the arrival of diaspores in degraded areas, and showing the importance of birds in this process.
