“…in Makino et al ). Irrigation ponds in Japan are inhabited by various freshwater fish species (Mitsuo et al ; Natsumeda et al ), many of which can be planktivorous at least for limited periods of their life cycle. A smaller body size could be a favorable factor in the presence of planktivorous fish due to their size‐selective predation on larger prey organisms (Lampert and Sommer ).…”

In copepods, morphologically‐indistinguishable but genetically‐different cryptic species complexes are frequently found, such as the Acanthodiaptomus pacificus complex that is commonly found in Japanese lakes and ponds. In the present study, the fauna of Japanese freshwater calanoid copepods were extensively reexamined using molecular techniques, and the autecology of each calanoid species was deduced based on the molecular identifications. Specimens were collected throughout Japan, identified by their morphological diagnostic characteristics, and then sequenced for the mitochondrial cytochrome c oxidase subunit 1 (mtCOI). In total, 13 species were found in the present study, and in most cases, only one species was collected from each waterbody. The A. pacificus complex occurred not only in high mountain lakes and pools of mountain moors but also in water bodies on low‐altitude plains. The occurrence of the other species was restricted to low‐altitude waterbodies, which were mostly man‐made irrigation ponds. Heliodiaptomus nipponicus and Neutrodiaptomus formosus, which are endemic to Japan, were found only in irrigation ponds, indicating that artificial waterbodies are currently indispensable to maintain the diversity of Japanese freshwater zooplankton. The results of mtCOI sequencing revealed the existence of putative cryptic species complexes such as Neutrodiaptomus formosus in Japan, and Neodiaptomus schmackeri, Sinodiaptomus sarsi, Heliodiaptomus kikuchii, and Eurytemora affinis across their Asian range. It is thus strongly recommended that any outcome of the freshwater zooplankton monitoring programs always be supplemented with DNA sequences in order to render that outcome sound and reliable also for future studies.

“…Indeed, M. salmoides is a top predator introduced in more than 50 countries for sports fishing (Jackson 2002, Froese andPauly 2016), including Neotropical reservoirs (Britton and Orsi 2012). As a large and widespread fish, M. salmoides reduced and/or extirpated the native fish fauna in many places (Jackson 2002, Takamura 2007, Shelton et al 2008, Ellender et al 2011, Natsumeda et al 2015, exerting a stronger predation pressure than native predators (Alexander et al 2014) or other non-natives (Trumpickas et al 2011). Along with M. salmoides, adverse ecological effects due to the introduction of tilapiine fishes have been reported throughout the world (Deines et al 2016).…”

Benthification, biotic homogenization behind the trophic downgrading in altered ecosystems

Several dozen fish species have been introduced into Neotropical waters, causing significant biotic changes that include deterministic predation interactions with ecosystem effects. In general, reservoirs are preferred over lakes as places for stocking policies, due to their artificial aspect, consequently promoting fish introductions. In a meta-analytic approach, we compared the biomass of plankton-feeding (and top predators) with bottom-feeding fish species between reservoirs and lakes, considering the influence of invaders and trophic levels. Among the 26 ecosystems (12 reservoirs and 14 lakes), there is a dominance of non-native bottom-feeding species in artificial environments. We revealed a mechanism behind this dominance in a study case, a tendency for trophic downgrading and biotic homogenization based on interactions between an expatriate invasive centrarchid (sunfish family) predator from North America (the largemouth bass Micropterus salmoides) and two omnivorous cichlids from Africa in novel environmental contexts in Brazil (the benthification process). Both juvenile and adult largemouth bass are keystone predators in aquatic food webs in both their native and introduced ranges. The omnivore-detritivore tilapiines Oreochromis spp. and the phytophagous-omnivorous Coptodon spp. are species that exhibits strong generalist tendencies. Such species feed on the omnivore and detritivore compartments, enhancing detritus cycling among a large variety of d 13 C sources. Since their consumption is disproportionate, facilitation of other species occurs with multiplicative effects in the environment. Interactions between invasive species, that is, when an invasive predator (bird, fish, or invertebrate) eats an invasive prey (mainly fish and invertebrates), can serve to highlight biotic homogenization on fresh waters.

“…In small farm ponds, largemouth bass can drastically alter the fish community through predation, sometimes resulting in local extinction of their prey species (Maezono and Miyashita 2003;Tsunoda and Mitsuo 2012;Natsumeda et al 2015). Predation on fish typically increases the growth and survival rates of largemouth bass due to the high energy content of fish (Keast and Eadie 1985;Olson 1996;Ludsin and DeVries 1997).…”

“…Predation on fish typically increases the growth and survival rates of largemouth bass due to the high energy content of fish (Keast and Eadie 1985;Olson 1996;Ludsin and DeVries 1997). Largemouth bass are also found in small farm ponds that lack prey fish (e.g., Maezono and Miyashita 2003;Natsumeda et al 2015), indicating that largemouth bass may sustain their populations under conditions of scarcity of prey fish. Largemouth bass are known to feed on conspecifics (e.g., Timmons et al 1980;Keast 1985;Johnson and Post 1996).…”
