En este artículo realizamos un análisis de las especies de plantas y vertebrados amenazadas y de aquellas con datos insuficientes del departamento de Loreto, el más grande y uno de los más biodiversos del Perú, con el fin de identificar las principales amenazas que soportan, identificar los vacíos de información y comparar la congruencia entre la lista nacional y la global. Uniendo ambas listas, en Loreto se ha registrado 226 especies consideradas amenazadas. Existen grandes diferencias entre la lista nacional y la global, principalmente para plantas y peces. La principal amenaza registrada es la pérdida de hábitat, que afecta a la mayor parte de las especies de vertebrados terrestres amenazados. Existen grandes vacíos de inf...

In Peru, the information published on the subject is scarce and is many times restricted to gray literature, complicating the analysis of the problem and the wildlife management. In this publication 23 species of vertebrates naturalized in Peru were identified, and the known information on its dispersion in the country, current distribution and impacts on natural environments was summarized. In addition, 8 species that were object of failed intents of introduction to natural environments or whose naturalized populations were extinguished were identified, as well as 10 species of vertebrates whose naturalization is probable but should
be verified. This information could be the base for the creation of a research plan on the naturalized vertebrates in Peru and their impacts.

It is distributed in coastal zones from southwestern Ecuador to west-central Peru; ranging in elevation from sea level to at least 1,000 m and possibly 2,000 m. L. sechurae is an opportunistic omnivore with the capability of being a strict vegetarian when necessary. Habitat preferences include desert environments and adjacent beaches, cultivated areas, dry forests, foothills, sea cliffs, and the western slopes of the Andes. L. sechurae increases seed dispersion for some plant species. It is considered Near Threatened by the International Union for Conservation of Nature and Natural Resources.

In this study, the genetic structure of the pampas cat (Leopardus colocolo), a widely distributed felid, was determined and linked to ancient climate fluctuations on the Andean region.

to our results the current geographic distribution of the European hare, would cover practically all of Argentina, Chile and Uruguay, southeastern Peru, southwestern Bolivia, southeastern Paraguay, and central part of southern Brazil. During the process of invading new areas, the hare has occupied very dissimilar environments, from the bushy steppes and Andean deserts of Bolivia and Peru to the dry and humid forests and wooded savannahs of Paraguay and Brazil. This would explain the variation observed in the dispersal rates that varied between 10 and 37 km/year.

In addition, we evaluate the presence of the Andean cat from interviews with local inhabitants. These new records extend the known Andean cat distribution an extra 892 km northwest and show that pampas cats occupy a great diversity of habitats throughout the Peruvian coast and Andes.

The purpose of the interviews were to obtain data regarding the use and attitudes towards the species, as well as to elaborate conservation recommendations. Rural residents pursue this species (68.3%) or view it with indifference (31.70%). In just one particular case (Santa Catalina de Chongoyape, in Lambayeque), residents have recently started protecting the animal for its value in tourist endeavors and for seed dispersal. Rural residents hunt the Sechuran fox because it eats chickens and guinea pigs (95% of those surveyed), as well as vegetables and stored foods
(13.3%). Some respondents also noted the suspected (but not proven) role of the Sechuran fox as a predator of goats (10%). The common uses of the Sechuran fox comprise selling the animal as a
pet and for the fabrication of witchcraft items (used by shamans), amulets and other crafts. The species is used by shamans to call upon spirits and get stronger prophesy powers (100% of those
surveyed), and to treat respiratory and stomach ailments with its fat (15.6%).

In the present study we increased the samples sizes to 235 individuals for L. pajeros and 115 individuals for L. jacobita, effectively making these samples the largest to date for these two species.
