DETECTION OF INFECTION WITH Toxoplasma gondii IN MANATEES (Trichechus inunguis) OF THE PERUVIAN AMAZON Acta biol.Colomb.
DELGADO,PATRICK MATHEWS; PEREA,NOFRE SANCHEZ; MATHEWS DELGADO,JONH PAUL; GARCIA,CLAUDIA BIFFI; MALHEIROS,ANTONIO FRANCISCO; GARCIA DAVILA,CARMEN ROSA.
The Amazonian manatee (Trichechus inunguis) is an aquatic mammal that inhabits freshwater environments and is endemic to the Amazon Basin. The presence of Toxoplasma gondii antibodies was investigated in 19 manatees in one rescue unit in the northern region of Peru. Antibodies to T. gondii were detected in 12 (63.2 %) of 19 animals by using the modified agglutination test (titer, 1:25), and no association between sex and age of the animals and the presence of T. gondii antibodies was observed (p < 0.05). The results suggest a contamination by T. gondii oocysts in the aquatic environment where these animals live.

The parasitism of Ixodes luciae (Acari: Ixodidae) on marsupials and rodents in Peruvian Amazon Acta Amazonica
Díaz,María Mónica; Nava,Santiago; Guglielmone,Alberto Alejandro.
In this work the infestation with I. luciae on Didelphimorphia and Rodentia in different environments of Peruvian Amazon was studied. Didelphimorphia was represented by the family Didelphidae. Specimens belonging to Caluromys lanatus, Didelphis marsupialis, Marmosops sp.2, Metachirus nudicaudatus, Philander andersoni and Philander opossum were infested with adults I. luciae and one Micoureus sp. was infested with larvae. In Rodentia, the infestation with I. luciae nymphs was restricted to Hylaeamys perenensis, Hylaeamys yunganus and Oligoryzomys microtis, while one Oecomys bicolor (all Cricetidae) was infested with larvae of this species. The few larvae were found on rodents captured in primary forest. The only significant difference (P < 0.05) in...

The prevalence of enteropathy due to Strongyloidiasis in Puerto Maldonado (Peruvian Amazon) BJID
Egido,J. M.; De Diego,J. A.; Penin,P..
Human strongyloidiasis is an important health problem in the southeast region of Peruvian Amazon, due to its prevalence and long term morbidity. An epidemiological study was conducted in the Peruvian Amazon area of Puerto Maldonado to determine the prevalence of strongyloidiasis in the population. Stool samples were collected from 1,133 patients at the outpatient department of our clinic. Strongyloidiasis affected 221 examined patients (20%). Prevalence was highest in males, mostly in children and elderly men. People living in urban and marginal urban areas, those coming from outside the region, and Andean people, showed the highest prevalences. Pre-school children were more likely to be parasitized than older children. The most common symptoms were...

Transportation costs, agricultural expansion and tropical deforestation: Theory and evidence from Peru Ciencia e Investigación Agraria
Lucich,Iván M; Villena,Mauricio G; Quinteros,María José.
The growth of urban areas adjacent to forest areas, as well as international trade growth, has accelerated the demand for food. These areas of growth have led to the deforestation of tropical forests, a process that contributes negatively to climate change, and a decline in the provision of environmental services and biodiversity. This article seeks to propose and simulate a theoretical model of optimal control at the household level. This model is used to explain the dynamics of forest loss by expansion of the agricultural frontier. Under these conditions, based on tradable permanent crops, farmers decide whether to install new areas for cultivation or manage existing ones in a context of increasing transportation costs. We simulate a theoretical model...

Updated List and identification key of 219 tree species of white sand forests of the Allpahuayo Mishana National Reserve, Loreto, Peru Acta Amazonica
GOMEZ,Ricardo ZARATE; VARGAS,Tony Jonatan MORI; AREVALO,Fredy Francisco RAMIREZ; DOZA,Hilda Paulette DAVILA; GONZALES,George Pepe GALLARDO; HUAYMACARI,Geancarlo COHELLO.
White sand forests, although low in nutrients, are characterized not only by several endemic species of plants but also by several monodominant species. In general, plants in this forest have noticeably thin stems. The aim of this work was to elaborate a parallel dichotomous key for the identification of Angiosperm tree species occurring on white sand forests at the Allpahuayo Mishana National Reserve, Loreto, Peru. We compiled a list of species from several publications in order to have the most comprehensive list of species that occur on white sand forest. We found 219 species of Angiosperm, the more abundant species were Pachira brevipes (26.27%), Caraipa utilis (17.90%), Dicymbe uaiparuensis (13.27%), Dendropanax umbellatus (3.28%), Sloanea spathulata...
