Abstract
RESUMO Estudos com impacto de desastres naturais sobre a fauna são raros na literatura científica. Considerando Lontra longicaudis (Olfers, 1818), informações publicadas não foram encontradas. O presente estudo buscou determinar se os deslizamentos de terra ocorridos em março de 2011 em parte das montanhas da Serra da Prata (Paraná, Brasil) afetaram de alguma forma a ocorrência da Lontra Neotropical no local impactado. Com esse propósito, a área estudada compreendeu um rio afetado (Rio Santa Cruz - RSC) da face leste dessa serra que foi comparado com outro não afetado (Rio das Pombas - RP), localizado na mesma face da serra e com características semelhantes às originais do RSC. A área de estudo está situada no Parque Nacional de Saint-Hilaire/Lange (PNSHL). Foram realizadas sete campanhas a partir do limite altitudinal do PNSHL (60 m s.n.m) para montante entre agosto de 2012 e julho de 2013. As campanhas consistiram de busca ativa por vestígios (fezes, pegadas, arranhados) e tocas de lontras ao longo de 3 km de margens e leito. Registros de outros mamíferos também foram observados. Cada evidência foi anotada em caderneta de campo, fotografada e georreferenciada. As tocas foram monitoradas ao longo das campanhas. Considerando as lontras, foram registrados 102 vestígios (11 arranhados, 11 pegadas e 80 fezes) e 17 tocas no rio não afetado (RP); e o rio afetado (RSC) apresentou apenas quatro vestígios (três pegadas, uma amostra fecal) e uma toca. Registros de outros mamíferos denotaram a presença de oito táxons no RP e 14 táxons no RSC. As diferenças conspícuas entre a quantidade de vestígios da presença das lontras indicam que o desastre natural afetou a população de lontras do RSC e mesmo dois anos após o evento as lontras retornaram apenas discretamente ao rio afetado. Por outro lado, outras espécies de mamíferos como Cuniculus paca (Linnaeus, 1758), reocuparam as margens abundantemente.

Abstract
The Neotropical otter (Lontra longicaudis) is a medium-sized semiaquatic carnivore with a broad distribution in the Neotropical region. Despite being apparently common in many areas, it is one of the least known otters, and genetic studies on this species are scarce. Here, we have investigated its genetic diversity, population structure, and demographic history across a large portion of its geographic range by analyzing 1471 base pairs (bp) of mitochondrial DNA from 52 individuals. Our results indicate that L. longicaudis presents high levels of genetic diversity and a consistent phylogeographic pattern, suggesting the existence of at least 4 distinct evolutionary lineages in South America. The observed phylogeographic partitions are partially congruent with the subspecies classification previously proposed for this species. Coalescence-based analyses indicate that Neotropical otter mitochondrial DNA lineages have shared a rather recent common ancestor, approximately 0.5 Ma, and have subsequently diversified into the observed phylogroups. A consistent scenario of recent population expansion was identified in Eastern South America based on several complementary analyses of historical demography. The results obtained here provide novel insights on the evolutionary history of this largely unknown Neotropical mustelid and should be useful to design conservation and management policies on behalf of this species and its habitats.

Abstract
The giant otter, Pteronura brasiliensis, occupies a range including the major drainage basins of South America, yet the degree of structure that exists within and among populations inhabiting these drainages is unknown. We sequenced portions of the mitochondrial DNA (mtDNA) cytochrome b (612bp) and control region (383 bp) genes in order to determine patterns of genetic variation within the species. We found high levels of mtDNA haplotype diversity (h = 0.93 overall) and support for subdivision into four distinct groups of populations, representing important centers of genetic diversity and useful units for prioritizing conservation within the giant otter. We tested these results against the predictions of three hypotheses of Amazonian diversification (Pleistocene Refugia, Paleogeography, and Hydrogeology). While the phylogeographic pattern conformed to the predictions of the Refugia Hypothesis, molecular dating using a relaxed clock revealed the phylogroups diverged from one another between 1.69 and 0.84 Ma, ruling out the influence of Late Pleistocene glacial refugia. However, the role of Plio-Pleistocene climate change could not be rejected. While the molecular dating also makes the influence of geological arches according to the Paleogeography Hypothesis extremely unlikely, the recent Pliocene formation of the Fitzcarrald Arch and its effect of subsequently altering drainage pattern could not be rejected. The data presented here support the interactions of both climatic and hydrological changes resulting from geological activity in the Plio-Pleistocene, in shaping the phylogeographic structure of the giant otter.

Abstract
The evolutionary history of a species can be revealed by phylogeographical analysis; nevertheless, not only historical but also contemporary processes can imprint on the distribution of genetic diversity. We report on the phylogeny of Lontra ssp. in South America, and the role of spatial heterogeneity in shaping the distribution and population structure of the endangered marine otter, Lontra felina. Analyzing a total of 2261 bp of mitochondrial DNA (mtDNA) revealed the recent divergence of L. felina from L. provocax. A strong population structure (Φ(st) = 0.83, P < 0.0001) and a significant pattern of isolation by distance were described for L. felina (n = 168) across a wide geographical distribution (13°53'S to 43°36'S). Lontra felina mtDNA phylogeny is composed of 2 main clades: a clade from Peru and another composed of Chilean haplotypes. Northern populations show different divergent lineages and higher genetic diversity when compared with more recently colonized southern populations. Furthermore, long sandy beaches seem to act as barriers to dispersal, creating 2 evolutionary significant units in agreement with subspecies previous description, and at least 5 different management units (MUs). At a fine spatial scale, the size of rocky seashore patches, the distance between patches and anthropogenic factors also play important roles in species gene flow.
