We present the first study that evaluates jaguar-puma interactions in the arid lands of northern Mexico, where jaguars have their northernmost breeding population and both predators are persecuted for livestock depredation. We tested whether jaguars are the dominant species in this unique ecosystem, where: (1) pumas outnumber jaguars, (2) pumas are better adapted to arid environments, and (3) jaguars and pumas are of similar size. We analyzed four years of data with two approaches; a two species conditional occupancy model and an activity patterns analysis. We used camera location and prey presence as covariates for jaguar and puma detection and presence probabilities. We also explored overlap in activities of predators and prey. Where both species were detected, peccary presence was positively correlated with both jaguar and puma presence, whereas in areas where jaguars were detected but pumas were not, deer presence explained the probability of jaguar presence. We found that both predators were more likely to co-occur together than to be found independently, and so we rejected the hypothesis that jaguars were the dominant species in our study area. Predators were mainly nocturnal and their activity patterns overlapped by 60%. Jaguar, as compared with puma, overlapped more with deer and calves; puma overlapped with calves more than with other prey, suggesting a preference. We believe exploring predator relationships at different scales may help elucidate mechanisms that regulate their coexistence.

The writings of the U.S. scholar Philip Wayne Powell have had an enduring influence on the historiography of colonial Mexico and the Spanish borderlands. But his writings have never been examined as a unified corpus, and so the deeply reactionary political ideology that lay behind them has never been well understood. By analyzing Powell’s political convictions, this article shows how contemporary scholarship on the conquest of northern Mexico can emerge from Powell’s long shadow. Los escritos del estudioso estadounidense Philip Wayne Powell han ejercido una influencia perdurable sobre la historiografía del México colonial y las zonas fronterizas españolas. Sin embargo, dichos escritos nunca han sido examinados como un corpus unificado, de manera que la ideología política profundamente reaccionaria detrás de ellos nunca ha sido bien comprendida. Al analizar las convicciones políticas de Powell, el presente artículo muestra cómo puede surgir un conocimiento contemporáneo sobre la conquista del norte de México a partir de la larga sombra de Powell.

Texas Revolution

Between 1820 and 1827 approximately 1,800 U.S. citizens immigrated to northern Mexico as part of that country’s empresario program, in which the federal government granted foreigners land if they promised to develop and secure the region. Historians have long argued that these settlers, traditionally seen as the vanguard of Manifest Destiny, were attracted to Mexico for its cheap land and rich natural resources. Such interpretations have lent a tone of inevitability to events like the Texas Revolution. This article argues that the early members of these groups were attracted to Mexico for chiefly political reasons. At a time when the United States appeared to be turning away from its commitment to a weak federal government, Mexico was establishing itself on a constitution that insured local sovereignty and autonomy. Thus, the Texas Revolution was far from the result of two irreconcilable peoples and cultures. Moreover, the role that these settlers played in the United States’ acquisition of not just Texas, but ultimately half of Mexico’s national territory, was more paradoxical than inevitable.

Small Valley

The recent discovery of a pit house village, 40 km northwest of Monterrey, challenges the conventional view of inland northeastern Mexico as the domain of purely nomadic hunters and gatherers throughout prehistory. Las Casitas consists of fifty-three subterranean rooms and forty-eight smaller depressions aligned in three slightly arcuate tiers in a small valley adjacent to Boca de Potrerillos, an extremely large open campsite and petroglyph complex that is now an archeological park. Other features of the site are some 325 hearths that surround the depressions and a very limited artifact assemblage numbering only thirty-seven items. Two hearths produced radiocarbon samples that date site occupancy to approximately a.d. 1450, just prior to the arrival of the Spanish in the New World. Las Casitas provides the first evidence of semi-sedentary, surplus producing populations in central northeastern Mexico.
