Mayflies are aquatic insects belonging to the order Ephemeroptera. This order is part of an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies. Over 3,000 species of mayfly are known worldwide, grouped into over 400 genera in 42 families.
Blanding's turtle is a semi-aquatic turtle of the family Emydidae. This species is native to central and eastern parts of Canada and the United States. It is considered to be an endangered species throughout much of its range. Blanding's turtle is of interest in longevity research, as it shows few or no common signs of aging and is physically active and capable of reproduction into eight or nine decades of life.
Sturgeon Bay is an arm of Green Bay extending southeastward approximately 10 miles into the Door Peninsula at the city of Sturgeon Bay, located approximately halfway up the Door Peninsula. The bay is connected to Lake Michigan by the Sturgeon Bay Ship Canal. The Potawatomi name for Sturgeon Bay is "Na-ma-we-qui-tong".
The tangerine darter or river slick is a small species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is found in the eastern United States. It grows to a length of 4.3 to 7.1 inches, males being bright orange-red while females are yellow. It is insectivorous, picking insect larvae off aquatic plants and the riverbed, and sometimes rolling small stones over to expose prey. It breeds in late spring and early summer, typically in shallow sandy or gravelly riffles. Pollution and habitat degradation may be a problem in parts of its range, however it is a fairly common fish with a wide range and the International Union for Conservation of Nature has classified its conservation status as being of "least concern".
Acanthametropus is a genus of mayflies in the family Acanthametropodidae. There are at least two described species in Acanthametropus.
The sand shiner is a widespread North American species of freshwater fish in the family Cyprinidae. Sand shiners live in open clear water streams with sandy bottoms where they feed in schools on aquatic and terrestrial insects, bottom ooze and diatoms.
Baetis is a genus of mayflies of the family Baetidae, known as the blue-winged olive to anglers. There are at least 150 described species in Baetis. They are distributed worldwide, with the most variety in North America and northern Europe.
Stenacron is a genus in the family Heptageniidae, the flat-headed mayflies. Almost all species are distributed across eastern North America.
The ironcolor shiner is a species of freshwater ray-finned fish from the family Cyprinidae, the minnows and carps. It is a widespread species in streams and rivers in eastern North America.
The fantail darter is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is widely distributed across streams in North America.
Bigeye chub is a species of freshwater fish in the carp family (Cyprinidae).
The Starhead topminnow is a native United States species that ranges from the Ouachita River drainage in Louisiana, the Big Black river in Mississippi, and extends northward into the Mississippi River and Lake Michigan basins to the southern Michigan and southern Wisconsin areas. The Starhead topminnow is endangered due to the removal of aquatic vegetation and the continued development of land that infringes on its habitat.
Etheostoma gracile, the slough darter, is a small species of ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae which includes the perches, ruffs and pike-perches. It inhabits slow to moderately flowing waters and with substrates that are predominantly mud, silt, or sand. Major food sources include chironomids, copepods, and cladocerans, as well as mayflies in the spring. Adults reach 35 to 50 mm total length. It is one of the 324 species of fish found in Tennessee.
The Christmas darter i is a species of ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae which includes the perches, ruffes and pike-perches. It is found in the Savannah, Ogeechee and Altamaha catchment areas in South Carolina and Georgia. It is a small but colorful fish, typically less than 5 cm (2 in) in total length, with blackish, red and green streaks on its flanks. Green and red are associated with Christmas, hence the common name Christmas darter. Like other darters, it lives on or close to the stream-bed, in riffles and vegetation-laden stretches of small rivers, creeks and spring-fed streams. It feeds on aquatic insects and probably breeds in the spring, but its biology and behavior are poorly known.
Iswaeon is a genus of small minnow mayflies in the family Baetidae. There are at least three described species in Iswaeon.
Kintrishi Strict Nature Reserve is a protected area in Kobuleti Municipality, Adjara region of Georgia in the upper part of the Kintrishi River at an altitude of 300–2,500 meters above sea level between the village of Tskhemvani (Tskhemlovana) and Khino Mountain in the Meskheti Range. It was established in 1959 to preserve relict humid forests and wetlands, in addition to its high number of endemic and threatened flora and fauna. Because of the ancient forests and high biodiversity within the nature reserve, it was inscribed on the UNESCO World Heritage List in 2021 as part of the Colchic Rainforests and Wetlands site.
Siphlonisca aerodromia, commonly known as the Tomah mayfly, is an extremely rare species and has only been documented less than 100 times. It was once thought to only known to occur in New York and Northern Maine, but has been since found more recently in eastern Canada as well. The Tomah mayfly is an endangered species and is listed as threatened in both New York and Maine. Its abundance is unknown. The Tomah mayfly is the only species within the monotypic genus Siphlonisca. The Tomah mayfly is a habitat specialist and an indicator species. Adults only live for a few days as they deposit eggs into rivers and streams. Nymphs hatch from eggs and migrate to the floodplains during springtime and following snow melt. They spend most of their lives in the floodplains, feeding on other aquatic invertebrates in order to grow rapidly. The Tomah mayfly was considered as a flagship species and led to the decision not to dam a stream and flood a sedge meadow and therefore conserve the ecosystem.
