Histochemical characteristics of macrophages of butterfly splitfin Ameca splendens. Folia Biologica (Kraków) 67: 53-60. The butterfly splitfin (Ameca splendens) is a fish species that belongs to the Goodeidae family. The biology of this species, which is today at risk of extinction in its natural habitats, has not been fully explored. The objective of the present study was to characterize melanomacrophages (MMs) and the melanomacrophage centers (MMCs) that they form, associated with the immunological system of butterfly splitfin. Butterfly splitfin is a potential new model species with a placenta for scientific research. In addition, knowledge about the location and characteristics of MMCs will allow the effective development of a conservation strategy for this species and monitoring of the natural environment. The results of histological analyses show that the immune system of fish aged 1 dph was completely developed. Single MMs were observed in hepatic sinusoids and in head kidney and their agglomerations were noticed in the exocrine pancreas and in the spleen. Hemosiderin was detected in single MMs in the head kidney of fish aged 1 dph, and in the spleen, exocrine pancreas and liver of older fish. -
The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish

These taxa survive as small, isolated populations in remote streams and springs and evolved to mtDNA tolerate extreme conditions of high temperature and low dissolved oxygen. Both species have experienced severe Conservation population declines over the last 50–60 years that led to some subspecies being categorized with protected status Pahrump poolfish under the U.S. Endangered Species Act. Here we report the first sequencing of the complete mitochondrial DNA White River springfish Endangered species genomes for both E. l. latos and the moapae subspecies of C. baileyi. Complete mitogenomes of 16,546 bp Fish nucleotides were obtained from two E. l. latos individuals collected from introduced populations at Spring Desert Mountain Ranch State Park and Shoshone Ponds Natural Area, Nevada, USA, while a single mitogenome of 16,537 bp was sequenced for C. -

Tomelleri U.S. Fish and Wildliffee Service Nevada Fish and Wilddlife Office Reno, Nevada December 14, 2012 5-YEAR REVIEW Hiko White River Springfish (Crenichthys baileyi grandis) and White River Springfish (Crenichthys baileyi baileyi) I. GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (USFWS) is required by section 4(c)(2) of the Endangered Species Act (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing of a species as endangered or threatened is based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of a species. In the 5-year review, we consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed or last reviewed. -

(January 2018). 1 1 Native Range and Status in the United States Native Range From Fuller (2018): “This species is confined to a very small area, the Río Ameca basin, on the Pacific Slope of western Mexico (Miller and Fitzsimons 1971).” From Goodeid Working Group (2018): “This species comes from the Pacific Slope and inhabits the Río Ameca and its tributary, the Río Teuchitlán in Jalisco. More habitats in the ichthyological [sic] closely connected Sayula valley have been detected quite recently.” Status in the United States From Fuller (2018): “Reported from Nevada. Records are more than 25 years old and the current status is not known to us. One individual was taken in November 1981 (museum specimen) and another in August 1983 from Rodgers Spring, Nevada (Courtenay and Deacon 1983, Deacon and Williams 1984). Others were seen and not collected (Courtenay, personal communication).” From Goodeid Working Group (2018): “Miller reported, that on 6 May 1982, this species was collected in Roger's Spring, Clark County, Nevada, (pers. comm. to Miller by P.J. Unmack) where it is now extirpated. It had been exposed there with several other exotic species (Deacon [and Williams] 1984).” From FAO (2018): “Status of the introduced species in the wild: Probably not established.” From Froese and Pauly (2018): “Raised commercially in Florida, U.S.A.” Means of Introductions in the United States From Fuller (2018): “Probably an aquarium release.” Remarks From Fuller (2018): “Synonyms and Other Names: butterfly goodeid.” 2 From Goodeid Working Group (2018): “Some hybridisation attempts have been undertaken with the Butterfly Splitfin to solve its relationship. -
Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

Life in the department was normal and very active until March when the state declared a shelter in place. Classes turned 100% remote with a 3-day notice. No one was allowed on campus so research came to a screeching halt. All doors were locked for 5 weeks. There were only a few people allowed inside to maintain living things – animals, plants, etc. In May, they required “return to research plans” from anyone wanting to return to research labs. -
