A REVISION of the GAMBUSIA NICARAGUENSIS SPECIES GROUP (PISCES:POECILIIDAE) by William L. Fink ABSTRACT in Addition to Gambusia
Reprinted from PUBLICATIONS OF THE GULF COAST RESEARCH LABORATORY MUSEUM 2:47-77, June 18, 1971 A REVISION OF THE GAMBUSIA NICARAGUENSIS SPECIES GROUP (PISCES:POECILIIDAE) by William L. Fink ABSTRACT In addition to Gambusia nicaraguensis, the species group includes G. wrayi, G. mela pleura and G. his paniolae sp. nov. G. gracilior is a junior synonym of G. wrayi and G. dominicensis is found to be a member of another species group. A key and zoogeographical notes are provided for the group. Rivas (1963) published on subgenera and species groups in the genus Gambusia. He used only gonopodial characters in defining his groups, and I believe that his system is both natural and practical. Subsequent investigation has shown a need to review his findings and to make adjust- ments in the system. I have found that G. dominicensis is a member of another species group and that the species referred to as dominicensis by Rivas (1963) is actually undescribed. Otherwise, I accept his G. nicara- guensis species group and feel that its revision will help clarify other prob- lems within the genus. METHODS.—Methods are those of Fink (1971).

When their wetland habitats dry out in summer, they burrow into the soil and remain there, motionless, breathing air, until the first decent flood of autumn refills the wetland and washes them from their refuge. Few fish species worldwide have such ability to survive for extended periods out of water. Early settlers in New Zealand were surprised to find live fish when digging vegetables from the earth. This ability to survive prolonged periods of drought allows them to colonise habitats that would be unsuitable for conventional fishes, which cannot survive out of water. These cryptic, nocturnal fish were probably once the most abundant freshwater fish in New Zealand. However, the loss of more than 90% of our wetlands over the past two centuries has confined them to a few refuge habitats still threatened by development of adjacent land. -
Western Mosquitofish Gambusia Affinis ILLINOIS RANGE
western mosquitofish Gambusia affinis Kingdom: Animalia FEATURES Phylum: Chordata The western mosquitofish male grows to about one Class: Osteichthyes inch in length, while the female attains a length of Order: Cyprinodontiformes about two inches. A dark, teardrop-shaped mark is present under each eye. Black spots can be seen on Family: Poeciliidae the dorsal and tail fins. The back is gray-green to ILLINOIS STATUS brown-yellow with a dark stripe from the head to the dorsal fin. The sides are silver or gray with a common, native yellow or blue sheen. Scales are present on the head, and scales on the body have dark edges, giving a cross-hatched effect. These fish tend to die in the summer that they become mature. BEHAVIORS The western mosquitofish may be found in the southern one-half of Illinois. This fish lives in areas of little current and plentiful vegetation in swamps, sloughs, backwaters, ponds, lakes and streams. The western mosquitofish reproduces three or four times during the summer. Fertilization is internal. After mating, sperm is stored in a pouch within the female and may be used to fertilize several broods. The eggs develop inside the female and hatch in three to four weeks. Young are born alive. A brood may contain very few or several hundred fish. Young develop rapidly and may reproduce in their first summer. The western mosquitofish swims near the ILLINOIS RANGE surface, alone or in small groups, eating plant and animal materials that includes insects, spiders, small crustaceans, snails and duckweeds. © Illinois Department of Natural Resources. 2020. -

Wong Abstract Two North American species of mosquitofish, the Western (Gambusia affinis Baird and Girard, 1853) and Eastern mosquitofish (G. holbrooki Girard, 1859), rank amongst the most invasive freshwater fishes worldwide. While the existing literature suggests that G. affinis was introduced to mainland China, empirical evidence supporting this assumption was limited, and the possibility remained that both species were introduced during campaigns attempting to reduce vectors of malaria and dengue fever. We used combined molecular information (based on phylogenetic analyses of sequence variation of the mitochondrial cytochrome b gene) and morphometric data (dorsal and anal fin ray counts) to confirm the presence -
Herpetofauna and Aquatic Macro-Invertebrate Use of the Kino Environmental Restoration Project (KERP)
Herpetofauna and Aquatic Macro-invertebrate Use of the Kino Environmental Restoration Project (KERP) Tucson, Pima County, Arizona Prepared for Pima County Regional Flood Control District Prepared by EPG, Inc. JANUARY 2007 - Plma County Regional FLOOD CONTROL DISTRICT MEMORANDUM Water Resources Regional Flood Control District DATE: January 5,2007 TO: Distribution FROM: Julia Fonseca SUBJECT: Kino Ecosystem Restoration Project Report The Ed Pastor Environmental Restoration ProjectiKino Ecosystem Restoration Project (KERP) is becoming an extraordinary urban wildlife resource. As such, the Pima County Regional Flood Control District (PCRFCD) contracted with the Environmental Planning Group (EPG) to gather observations of reptiles, amphibians, and aquatic insects at KERP. Water quality was also examined. The purpose of the work was to provide baseline data on current wildlife use of the KERP site, and to assess water quality for post-project aquatic wildlife conditions. I additionally requested sampling of macroinvertebrates at Agua Caliente Park and Sweetwater Wetlands in hopes that the differences in aquatic wildlife among the three sites might provide insights into the different habitats offered by KERF'. The results One of the most important wildlife benefits that KERP provides is aquatic habitat without predatory bullfrogs and non- native fish. Most other constructed ponds and wetlands in Tucson, such as the Sweetwater Wetlands and Agua Caliente pond, are fuIl of non-native predators which devastate native fish, amphibians and aquatic reptiles. The KERP Wetlands may provide an opportunity for reestablishing declining native herpetofauna. Provided that non- native fish, bullfrogs or crayfish are not introduced, KERP appears to provide adequate habitat for Sonoran Mud Turtles (Kinosternon sonoriense), Lowland Leopard Frogs (Rana yavapaiensis), and Mexican Gartersnakes (Tharnnophis eques) and Southwestern Woodhouse Toad (Bufo woodhousii australis). -

Conservation status: DD (IUCN 2004); EN B1+2bcd in the Red List of freshwater fish from Spain (Doadrio 2002). Identification: Iberian endemism. Morphological analyses revealed the existence of different morpho- types (Garcı´a-Berthou et al. 1989, Doadrio et al. 2002), however, the degree of differentiation is similar to that detected in closely related species. A. iberus differs from all other known species of Aphanius in the combination of 8 – 9 branched rays in the anal fin, 9 – 10 bran- ched rays in the dorsal fin, short and high caudal peduncle, and greater preorbital length than Aphanius baeticus (the most similar species). A. iberus is sexually dimorphic. Adult males show a color- ation pattern characterized by narrow silver transversal bars along the body side, which are continued on the caudal fin (3 – 4 bars). Females show numerous small dark spots on the body flanks which tend to form rows, one of them along the lateral line. Males (Total lengthmax £ 45 mm) are smaller overall than females (Total lengthmax £ 60 mm). -
