“…Predation relates to competition where alien fish also exert a high impact. It has been argued that alien species either have to occupy an empty niche or they have to be dominant (invasive) to establish a fast‐growing population (Matsuo & Ochiai ). Therefore, we assume that competition with native species plays a key role (average of 1.0 impact point per alien fish species in this category) and may still be underestimated.…”

Invasions by alien species are one of the major threats to the native environment. There are multifold attempts to counter alien species, but limited resources for mitigation or eradication programmes makes prioritisation indispensable. We used the generic impact scoring system to assess the impact of alien fish species in Europe. It prioritises species, but also offers the possibility to compare the impact of alien invasive species between different taxonomic groups. For alien fish in Europe, we compiled a list of 40 established species. By literature research, we assessed the environmental impact (through herbivory, predation, competition, disease transmission, hybridisation and ecosystem alteration) and economic impact (on agriculture, animal production, forestry, human infrastructure, human health and human social life) of each species. The goldfish/gibel complex Carassius auratus/C. gibelio scored the highest impact points, followed by the grass carp Ctenopharyngodon idella and the topmouth gudgeon Pseudorasbora parva. According to our analyses, alien fish species have the strongest impact on the environment through predation, followed by competition with native species. Besides negatively affecting animal production (mainly in aquaculture), alien fish have no pronounced economic impact. At the species level, C. auratus/C. gibelio show similar impact scores to the worst alien mammals in Europe. This study indicates that the generic impact scoring system is useful to investigate the impact of alien fish, also allowing cross‐taxa comparisons. Our results are therefore of major relevance for stakeholders and decision‐makers involved in management and eradication of alien fish species.

“…As their range has expanded, damage to crops by P. larvata has also increased. Furthermore, their diet overlaps with those of native carnivore species in Japan, such as the raccoon dog (Nyctereutes procyonoides), badger (Meles anakuma) and Japanese marten (Martes melampus) (Matsuo et al 2007;Matsuo and Ochiai 2009) and competition for food between them occurs. It is also reported that, in Chiba Prefecture (Kanto District: Fig.…”

Genetic population structure of the masked palm civet Paguma larvata, (Carnivora: Viverridae) in Japan, revealed from analysis of newly identified compound microsatellites

The masked palm civet Paguma larvata (Carnivora: Viverridae) in Japan has been phylogeographically considered an introduced species from Taiwan. To reveal the population structures and relationships among the P. larvata populations in Japan, seven compound microsatellite loci were isolated from the genome and genotyped for 287 individuals collected from the field. STRUCTURE analysis and factorial correspondence analysis of genotyping data revealed that animals from Japan were divided into four genetic clusters. Geographic distribution of the genetic clusters partly referred to sampling areas, indicating multiple introductions into distinct areas of Japan or independent founding events leading to the generation of different genetic clusters within introduced populations in Japan. The large genetic differentiation of populations in the Shikoku District from those in other areas within Japan suggests that there were at least two introduction routes into Japan, and a possibility that some founders from areas other than Taiwan were also involved in the introduction into Japan. The genetic variation within Japanese populations were not markedly reduced compared with that of Taiwan. The results indicated that the Japanese populations of P. larvata could have retained moderate genetic diversity during founding events, because of multiple introductions, or a large number or high genetic diversity of founders. Although some individuals in Japan showed a sign of admixture between different clusters, there is no evidence that such an admixture markedly increased the genetic diversity within Japanese populations.

“…Viable seeds are dispersed into deforested areas, but are most often deposited on hard surfaces that are unsuitable for germination, such as boulders, roads, and grave sites. There is less information available for P. larvata in Hong Kong because its feces are harder to locate (Wan 2009), but studies in central China (Zhou et al 2008a) and Japan (Matsuo & Ochiai 2009) suggest it prefers fruit when this is available. It was the only species seen to eat the large green fruits of Ilex chapaensis in Hong Kong, harvesting them directly from the tree and dropping many seeds from the mouth (Tsang & Corlett 2005).…”

In the present article, published and unpublished information regarding seed dispersal in the degraded landscape of Hong Kong, China, is reviewed. Information was available for 1681 native plant species, of which 1165 were assigned to probable seed dispersal modes. Endozoochory accounted for one-third (34.4%) of all species evaluated, half (54.4%) of those from forests, and more than two-thirds (69.2%) of all trees and tall shrubs. Wind dispersal (25.9%) and dispersal by an unknown agent (30.7%) accounted for most of the rest, with the unknown species mostly small-seeded herbs. Although the frugivore fauna of the Hong Kong region has been truncated since the late Pleistocene, there are few clear examples of failed mutualisms. The most striking is the absence of scatter-hoarding rodents from Hong Kong, despite the presence of forest trees that appear to require them for effective dispersal. There are also some large Lauraceae fruits that appear to be targeted at larger-gaped birds than currently present. Most endozoochorous species are dispersed by 3 small passerine birds (Pycnonotus jocosus, P. sinensis, and Zosterops japonicus), with larger birds, fruit bats (Cynopterus sphinx, Rousettus leschenaulti), rhesus macaques (Macaca mulatta), civets (Paguma larvata, Viverricula indica), and muntjacs (Muntiacus muntjac) accounting for the remainder. The low plant diversity in frugivore droppings, seed traps, and secondary vegetation suggests plant succession may be dispersal limited, although this has not been investigated experimentally. Planting underdispersed species is the simplest solution but, in the longer term, the (re)introduction of a scatter-hoarding rodent should be considered as well as that of other locally and regionally extinct frugivores.
