The blue-and-yellow macaw (Ara ararauna) is suffering from higher roadkill rates (RK) at the Emas National Park (ENP), an important Brazilian National Park in the Cerrado biome. This species is also a victim of nest poaching for illegal trade. We modeled the blue-and-yellow macaw population’s viability in ENP and how this viability is affected by roadkill and nest poaching. We hereby report that the species is critically at risk and could be extinct in about a decade when considering both threats. Without considering any threat, 150 individuals are necessary to maintain a viable population. When individuals are harvested at a roadkill rate of 0.008 individuals/km/year and at twice this level, the viability figures increase to 4500 and 7500 birds, respectively. For nest poaching, we estimated that 2000 individuals are required to maintain a viable population. When both threats are present, 5000 individuals are necessary. The dynamics of the population are highly sensitive to the age at which females reproduce for the first time and the proportion of reproducing adult females, followed by the rate of adult survival. Our model demonstrates how even a non-threatened highly mobile species, such as the blue-and-yellow macaw, may be at risk due to human activities.

This is a report of a revision of 565 herbarium specimens of lichens, lichenicolous or non-lichenized fungi and additional locality records of common species produced from a visit of the Russian-Finnish expedition to Vodlozersky National Park right after its foundation in 1991. The analyzed collection and field records represent the earliest information about the lichen flora of the territory of the park. In total, 177 species are listed including 173 lichens, 3 non-lichenized and 1 lichenicolous fungi. Xylographa rubescens is new to the Republic of Karelia. Twenty two species are reported for the first time for biogeographic province Karelia transonegensis; 47 species for the Karelian part of Vodlozersky National Park; and 17 species for the whole territory of the park.

In this paper, M. yanomami n. sp., from Brazilian Amazonia, Chaetacis bandeirante n. sp., from Central Brazil, and the males of M. gaujoni Simon, 1897 and M. ruschii (Mello-Leitão, 1945) n. comb. , respectively from Ecuador and Brazil, are described and illustrated for the first time. An ontogenetic series of the last development stages of both sexes of Micrathena excavata (C. L. Koch, 1836) is illustrated and briefly described. Adult females are larger and have longer legs and larger abdomens than adult males. Probably females undergo at least one additional moult before adulthood, compared to males. Micrathena ornata Mello-Leitão, 1932 is considered a junior synonym of M. plana (C. L. Koch, 1836), and M. mastonota Mello-Leitão 1940 is synonymized with M. horrida (Taczanowski, 1873). Acrosoma ruschii Mello-Leitão, 1945 is revalidated, transferred to Micrathena and considered a senior synonym of M. cicuta Gonzaga & Santos, 2004. Chaetacis necopinata (Chickering, 1960) is recorded for Brazil for the first time. Chaetacis incisa (Walckenaer, 1841) is considered a nomen dubium.

The Jaú National Park, located in the Amazon, is the largest National Park of Brazil and still its insect fauna is barely known. Herein we describe two new species of Psychodinae, Alepia iy sp. nov. and Parasetomima timmirima sp. nov., and report 19 other species of Psychodidae, subfamilies Phlebotominae, Psychodinae and Trichomyiinae collected from this Conservation Unit. Micrommatos Quate & Brown, represented by M. stephaniae Quate & Brown, and Platyplastinx culmosus Quate & Brown are recorded for the first time for Brazil. Among the collected phlebotomine sand fly species, three species have previously been implicated in transmission of Leishmania: Nyssomyia anduzei (Rozeboom), Psychodopygus ayrozai (Barretto & Coutinho) and Trichophoromyia ubiquitalis (Mangabeira).

Macroinvertebrate samples collected during spring-summer 2013 in high mountain rivers of the Ordesa and Monte Perdido National Park (Pyrenees) contained several Hydraena species (Coleoptera: Hydraenidae) where we found two genera of suctorian ciliates as epibionts: Tokophrya and Discophrya. The individuals of the genus Tokophrya probably belong to species Tokophrya stenostyla, being the first time that this species is observed attached on arthropods. Suctorians of the genus Discophrya were identified as a new species called Discophrya ordesae sp. n. The presence and abundance of epibionts was discussed in the frame of the biological and ecological characteristics of the species of Hydraena where they were found.

Measurement of nitrotyrosine in biological fluids and tissues is increasingly being used to monitor the production of reactive nitrogen species in vivo. The detection of nitrotyrosine in vivo has been reported with the use of a variety of methods including immunoassay, HPLC and GLC/MS. The validity of HPLC and immunoassays have been questioned with regard to their selectivity and sensitivity limits. In principle, the measurement of nitrotyrosine by GLC/MS permits a highly specific, highly sensitive and fully quantitative assay. The nitration of tyrosine under acidic conditions in the presence of nitrite is well documented. Derivatization for the full quantification of nitrotyrosine by using GLC/MS can lead to the artifactual nitration of tyrosine if performed under acidic conditions in the presence of nitrite. We describe a novel alkaline method for the hydrolysis and derivatization of nitrotyrosine and tyrosine, and demonstrate its applicability to the measurement of plasma concentrations of both free and protein-bound nitrotyrosine and tyrosine. A detection limit of 1 pg for nitrotyrosine and 100 pg for tyrosine has been achieved. Our method allows, for the first time, the analysis of free and protein-bound nitrotyrosine and tyrosine in biological samples. The plasma concentrations (means±S.E.M.) of free tyrosine and nitrotyrosine in eight normal subjects were 12±0.6 μg/ml and 14±0.7 ng/ml respectively. Plasma proteins contained tyrosine and nitrotyrosine at 60.7±1.7 μg/mg and 2.7±0.4 ng/mg respectively.

Campos Amazônicos National Park is a federal conservation unit that contains part of the largest Cerrado refuge in the southern part of Brazilian Amazonia. Recently, during a survey of aquatic insects in the park, specimens of the caddisfly genus Chimarra were collected. The primary objective of this paper, as a result of this effort, is to describe and illustrate the male adult of a new species in Chimarra (Chimarrita), Chimarra singularis sp. nov., and the immature stages of Chimarra usitatissima Flint 1971. Additionally, the distributions of C.(Chimarrita) akantha Blahnik 1997 and C. (Curgia) jugescens Flint 1998 are extended to the southern part of Amazonas state, and C. (Chimarrita) heppneri Blahnik 1997 is recorded for the first time in northern Brazil.

Wild dog Lycaon pictus and lion Panthera leo populations in the Kruger National Park appeared to undergo an increase during a drought period in the early 1990s. Newly established packs, high adult survival and pup productivity contributed to an increase in the wild dog population and evidence for high predation success during the height of the drought is presented. An increase in the lion density between 1989 and 1993 on the northern basalt plains, as well as changes in the structure of the population, seem to be related to changes in prey populations, particularly to a decline in numbers and condition of buffalo Syncerus cafer.
