The San Pedro Mezquital River is the seventh largest river in Mexico, and flows through the Sierra Madre Occidental into the Marismas Nacionales Biosphere Reserve, on the coast of the state of Nayarit. The present study is to conform a systematic checklist of fishes in the lower basin of the San Pedro Mezquital River. In total, 52 species were collected from 24 families. Four native species were collected (Atherinella crystallina, Poecilia butleri, Poeciliopsis latidens and Poeciliopsis prolifica) that are federally protected. Five of the collected species were new records for the state of Nayarit. This checklist constitutes a first approximation of the fish fauna present in the San Pedro Mezquital River. However, the construction of the Las Cruces dam upstream, will modify the basin hydrology, worsen the introduction of exotic species and create habitat loss, which can have immediate negative impacts on the fish communities in this region.

Protection Area

The Flora and Fauna Protection Area (Área de Protección de Flora y Fauna—ÁPFF) Cerro del Mohinora, is the highest mountain in northern Mexico, reaching an elevation of 3,300 meters. It constitutes one of the last high-elevation islands of alpine and subalpine vegetation known in the Sierra Madre Occidental, in the extreme southwestern part of Chihuahua. The ÁPFF Cerro del Mohinora is located near the state border and limits with Durango and Sinaloa. This type of ecosystem located at high altitudes is in danger of disappearing since only 1% or less of its original extension remains; it is considered a refuge for species with boreal affinities (McDonald et al. 2011).

Under the direction of J. Charles Kelley of Southern Illinois University, an anthropological field school carried out investigations in the State of Durango, Mexico, from June 22 to August 8, 1952, with the permission of the Instituto Nacional de Antropologia e Historia.Their camp was established on the rancho “Santa Barbara,” property of Fred Weicker, about 50 kms. west of Durango city, in the Sierra Madre Occidental. The camp was on the side of an arroyo, a branch of the Rio Mimbres, which after joining the Rio Chico, flows into the Rio Tunal. This becomes the Mesquital-San Pedro and flows into the Pacific through the State of Nayarit. The camp was approximately 2280 m. above sea level, near archaeological remains consisting of house-mounds, ceramics, and obsidian artifacts.

The Sierra Madre Sparrow (Xenospiza baileyi) is an endemic species of Mexico that is threatened with extinction. Its distribution is reported in two areas: One in the Transvolcanic Belt of central Mexico (La Cima) near Mexico City and the other in the Sierra Madre Occidental in northwestern Mexico (Ejido Ojo de Agua El Cazador) near the city of Durango, in the state of Durango. The habitat is the same in these two areas, and consists of sub-alpine grassland that is located in shallow valleys or shallows. In our case, "El Bajío la Cantera" of approximately 55 hectares, is mostly used in rainfed agriculture, protected from livestock grazing with wire fences, which in turn represents protection for remnants of grassland where they are the birds. “El Bajío la Cantera" belongs to Ejido 12 de Mayo, Municipality of San Dimas, Durango, where 28 males were detected singing along a 500 meter transect. This finding represents the population of the healthiest Sierra Madre Sparrow currently known, so it would be necessary to document their population trend over time. This information can help to evaluate and propose the creation of a special protection area for the species that involves joint government actions and ejidatarios tending to conserve the habitat during the reproductive season in order to increase and / or maintain the size of the population.

Diverse Cultures

The state of Durango, Mexico, is situated almost in the middle of the Sierra Madre Occidental. Nearly the entire state is rocky and mountainous and there are fairly large areas which are almost inaccessible though there are numerous fertile valleys which serve to produce the grain and herbage for the cattle which are important in the economy of the state. In the mountains and in the valleys may be found abundant evidence of the activities of man over what was likely a rather long period of time; there is evidence of what appear to be several rather diverse cultures though relatively little archaeological study has been made of these cultures thus far.In the mountains in the vicinity of Mezquital some 50 miles to the south of the city of Durango are numerous caves and rockshelters. It was in one of these caves that the writer discovered a bowl (Fig. 61) which conceivably may have been an “ancestor” of true pottery.

AbstractSeven species of introduced Carabidae are newly reported in Nova Scotia and Prince Edward Island. Trechus quadristriatus (Schrank), Amara ovata (Fabricius), and Harpalus rubripes (Duftschmid) are newly recorded in Atlantic Canada as a whole. Possible modes of introduction of these species to the region are discussed. Several may have been introduced in association with dry ballast shipments. Some may have arrived via natural dispersion from neighbouring areas; others appear to have been present and undetected for a considerable time. The possible impact of such introductions is also discussed. Synanthropic environments have higher proportions of introduced species than relatively undisturbed, native habitats. Some adventive species do become widespread in native environments; however, negative impacts on native species may not be readily apparent.

Abstract Senna comprises about 350 species worldwide, of which 80 species occur in Brazil. This work brings an update taxonomic treatment of Senna species in the state of Minas Gerais, the second most diverse state for the genus, through the morphological analysis of about 2,348 specimens from herbaria and fieldwork. Thirty-six species and 29 varieties were recognized, including 34 native species and 2 cultivated species. Of the 39 species reported in literature for the state, but 4 species were excluded from the list produced. The occurrence of Senna acuruensis was confirmed; S. macranthera var. striata and S. pilifera var. tubata are new records, and S. hirsuta var. acuminata is endemic to Minas Gerais. There are 28 species in the Cerrado, 26 species in the Atlantic Forest and 20 species in the Caatinga. The distribution of Senna pentagonia var. pentagonia is extended to include the Atlantic Forest. Identification keys, descriptions, illustrations, taxonomic comments and geographic distribution are provided for the species and varities.

Abstract This list contains information on the Drosophilidae that occur in the Brazilian state of Pará, Amazon biome, and an analysis of the current knowledge of Drosophilidae based on museum material and literature records. This list includes a detailed account of the material deposited in the entomological collections of the Museu Paraense Emílio Goeldi and Museu de Zoologia da Universidade de São Paulo, up to 2015. In total, 122 species of Drosophilidae were registered, including 27 new records for the state of Pará and 22 are new records for the Amazon; for instance, the genera Diathoneura and Rhinoleucophenga, and three new records for Brazil, (Drosophila fasciola, Diathoneura flavolineata and Drosophila neochracea). The state of Pará is the third state in Brazil in terms of numbers of species of Drosophilidae, with 17% locally native species. Despite the high species richness, there is still a lot to be known about the states's Drosophilidae fauna. This study highlights the importance of scientific collections, particularly as an aid to study regional biodiversity.

Anthropogenic Threats

The San Pedro–Mezquital River Basin is located in the southern Sierra Madre Occidental, at the Nearctic– Neotropical transition. The river traverses the Sierra through a canyon that reaches over 1000 m in depth. Based on examination of museum specimens, literature records, and our own collections, we documented the occurrence of 120 species (24.6% of the Mexican terrestrial mammals), 24 endemic to Mexico. Richness was comparable with other megadiverse areas of Mexico, and higher than any other Nearctic–Neotropical transition area, moreover species richness is likely to rise as survey continues. Contrary to expectation, distribution of mammals across the basin not only reflected the Nearctic–Neotropical divide, but a third fauna that is a mixture of tropical, temperate and desert species was identifiable at the canyon. Anthropogenic threats including damming of the river, uncontrolled cattle grazing, and pollution from domestic sources, call for effective management strategies to preserve one of the most biodiverse areas of Mexico.

Native Fishes

At the turn of the century, only one non-native species of fish, the common carp, was established in Illinois (Forbes and Richardson 1908). In contrast, by 1979, six non-native fishes were reproducing in Illinois (Smith 1979) and, in 1996, only 17 years later, seven more nonnative fishes have become established (Table 1). In addition to these 13 species, 9 non-native fishes are periodically stocked in Illinois or stray into the state from nearby states where they are stocked (Table 1). Because several of these fishes only recently have become introduced or are expanding their ranges in Illinois, they are not familiar to most residents of the state. The keys and descriptions in this publication are intended to assist in the identification and monitoring of the impacts of these 22 species. Also included for each species is a brief summary of its ecological and life history characteristics, and a discussion of its Illinois distribution. Additional information can be found in accounts by Smith (1979) and by Burr (1991), who reviewed various aspects of recent changes in the fish fauna of Illinois.
