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 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.

Special Protection

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.

Two New Species

The genus Lobelia is cosmopolitan and comprises 423 species in 18 sections. Lobelia sect. Stenotium is the most diverse group with 153 species, has a wide distribution in continental North America and is segregated into two subgroups based on the presence of spurred flowers. There are 16 spurred Lobelia species that occur in streamside or seep areas, throughout pine and oak mixed forests from USA to Costa Rica, but they are frequent along the Pacific slopes of the Sierra Madre Occidental (SMO), Mexico, where 10 species grow. In this paper we present a synopsis of the spurred species of Lobelia in the SMO and propose two new taxa. First, Lobelia rzedowskii is morphologically similar to L. ayersiae, L. cordifolia and L. endlichii but differs by its rosulate leaves, blades 0.5–1.5 × 0.4–1 cm, subsessile, racemose to paniculate inflorescences, with (4–)10–35(–191) flowers, flowers 4–6 mm long including hypanthium, spur 0.5–1 × 0.5–0.8 mm, with the lower two calyx lobes positioned at the middle portion of the spur, white corolla with a yellow spot above lobe sinuses on the throat and staminal tube 1.3–2.5 mm long. Second, Lobelia saturnini is morphologically similar to L. knoblochii, L. macrocentron, L. mcvaughii and L. villaregalis, but differs from them by leaves (2–)4–14(–17) mm long, petioles 2–6(–17) mm long, solitary flowers, flowers 12–16 mm long including hypanthium, hypanthium 1.2–2.5 mm long, spur 2–3 mm long, pedicels (1.3–)2–9(–12) cm long and anthers 1–2.2 mm long. We include an identification key for spurred species of Lobelia in the SMO, photographs, distribution notes with a map, and illustrations.

Coastal Strip

AbstractAn archaeological sequence for the Sinaloa coastal strip of western Mexico had previously been developed by Sauer and Brand, Isabel Kelly, and Gordon Ekholm. Investigations carried out by Southern Illinois University and associates from 1952 to 1958 in Durango, across the Sierra Madre Occidental to the east of Sinaloa, have established an independent archaeological sequence. The presence of trade pottery and other artifacts from Sinaloa in the Durango sites makes possible an independent check of the Sinaloa sequence. This cross correlation essentially confirms the basic Sinaloa sequence of (early to late) Chametla, Aztatlan, and Culiacan periods, but indicates that there is some overlap between these major horizons and that the Aztatlan period is actually divisible into three more or less sequent phases: an early Lolandis phase, an intermediate Acaponeta phase, and a terminal Guasave phase. Re-examination of the Sinaloa sequence confirms and expands these conclusions, resulting in this revision of the archaeological sequence for Sinaloa. For consistency, a revised terminology for the various phases is also presented.

SummaryIn this study I present data suggesting altitudinal movements of some species of foliage-gleaning insectivorous birds and related species of an oak-pine woodland of western Mexico. These movements can be regarded as short-distance or local migrations because the species involved breed in the woodlands and forests of the Sierra Madre Occidental highlands and winter in the tropical forests of the Pacific lowlands. Nine species of insectivorous birds out of 17 breed at the study site in the mountains of southern Durango and move to the lowlands in the winter; these can be regarded as short-distance or local migrants. In Mexico tropical deciduous and semi-deciduous forests are distributed mostly in the Pacific lowlands in the states of Sinaloa, Durango, Nayarit and Jalisco. Tropical forests of the Pacific lowlands are very important as wintering grounds for both North American and local west-Mexican migrants; however, there is only one protected area in western Mexico which to some degree includes these two types of tropical forests, and it is not located in the Sierra Madre Occidental, the most important mountain range in Mexico in terms of length and area covered. In addition, these tropical forests are the northern limit of the range for many tropical species. At present, these habitats are not threatened seriously by human activities (mainly forestry and cattle-raising) but this might change at any moment. At the study site the temperate highlands of southern Durango are already under the protection of “La Michilía” Biosphere Reserve, but a proposal to enlarge the area of the reserve to include the valley of the Río Mezquital and the western slope of the valley will increase the diversity of habitats, both temperate and tropical. As a consequence more bird species, as well as other taxa, will be protected in their natural environments. Such a proposal must be supported by field evidence on actual habitat use both during the breeding and wintering season, by local and long-distance migrants, in order to assess accurately the importance of this area as a representative place of western Mexico.

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).

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.

World Distribution

This contribution lists 37 new moss taxa from the State of Zacatecas, Mexico. The revised listing includes 115 species and varieties of mosses but unidentified specimens of Atrichum and Grimmia are not yet included. On account of their world distribution the taxa can be grouped in four elements: Wide Distribution, Mexican, Mesoamerican and Endemic. Fifty-seven per cent of this moss flora is widely distributed in Mexico while the remainder is known only from the Neovolcanic Belt northwards. Moss distribution in Zacatecas supports the state subdivision into two phytogeographical provinces: Sierra Madre Occidental and Altiplanicie. This moss flora seems to have originated in Tertiary times.
