Lake Shore Dr, Chicago IL 60605-2496 USA. 2 Department of Biological Sciences, University of Illinois at Chicago, 845 W. Taylor St, Chicago IL 60607 USA ABSTRACT: Recent surveys in Peru’s Manu National Park and Biosphere Reserve uncovered a new species of hystricognath rodent, a spiny rat (Echimyidae) with dense, soft fur. Inhabiting Andean cloud-forests at 1900 m, the new rodent belongs to a radiation of “brush- tailed tree rats” previously known only from the Amazon, Orinoco, and other lowland river drainages. Phylogenetic analysis of morphology (cranial and dental characters) unambiguously allies the new species with species of Isothrix. -
Parasite Communities of Tropical Forest Rodents: Influences of Microhabitat Structure and Specialization
PARASITE COMMUNITIES OF TROPICAL FOREST RODENTS: INFLUENCES OF MICROHABITAT STRUCTURE AND SPECIALIZATION By Ashley M. Winker Parasitism is the most common life style and has important implications for the ecology and evolution of hosts. Most organisms host multiple species of parasites, and parasite communities are frequently influenced by the degree of host specialization. Parasite communities are also influenced by their habitat – both the host itself and the habitat that the host occupies. Tropical forest rodents are ideal for examining hypotheses relating parasite community composition to host habitat and host specialization. Proechimys semispinosus and Hoplomys gymnurus are morphologically-similar echimyid rodents; however, P. semispinosus is more generalized, occupying a wider range of habitats. I predicted that P. semispinosus hosts a broader range of parasite species that are less host-specific than does H. gymnurus and that parasite communities of P. semispinosus are related to microhabitat structure, host density, and season. During two dry and wet seasons, individuals of the two rodent species were trapped along streams in central Panama to compare their parasites, and P. semispinosus was sampled on six plots of varying microhabitat structure in contiguous lowland forest to compare parasite loads to microhabitat structure. Such structure was quantified by measuring thirteen microhabitat variables, and dimensions were reduced to a smaller subset using factor analysis to define overall structure. Ectoparasites were collected from each individual, and blood smears were obtained to screen for filarial worms and trypanosomes. In support of my prediction, the habitat generalist ( P. semispinosus ) hosted more individual fleas, mites, and microfilaria; contrary to my prediction, the habitat specialist (H. -
Nine Karyomorphs for Spiny Rats of the Genus Proechimys (Echimyidae, Rodentia) from North and Central Brazil

Abstract Spiny rats of the genus Proechimys are morphologically diverse, widely distributed and have diploid numbers ranging from 2n = 14-16 to 2n = 62. In this paper we present cytogenetical data and brief comments on morphological and biogeographical issues related to spiny rats. In our sample of 42 spiny rats collected from 12 Brazilian Amazonian tropical rainforest and the Cerrado (Brazilian savanna) sites we detected nine karyological entities: four different karyomorphs with 2n = 30, three with 2n = 28, one with 2n = 15 and one with 2n = 44. Based on qualitative morphological characters these karyomorphs can be allocated to five species within the goeldii, guyannensis and longicaudatus species groups.

Piracicaba, São Paulo, Brasil Abstract: The Global Mammal Assessment (GMA) evaluates the risk of extinction for all species of mammals, providing important data on their status to national and global conservation agencies and conventions. We assessed all of the species of Brazilian rodents as part of the GMA activities of the International Union for the Conservation of Nature Species Survival Commission (IUCN SSC) Small Mammal Specialist Group. A total of 234 species were evaluated against the IUCN Red List Criteria and placed into one of eight categories. Although rodents do not have elevated extinction risk compared to mammals as a whole, several families of caviomorph rodents have high levels of either threat, data deficiency, or both. The family Echimyidae has a large number of species and one-third of those either are species of conservation concern or data deficient. -

Miranda10 Abstract Amazonia National Park is located in southwestern Para´ State in central Amazonia. The 10,707 km2 park is one of the largest protected areas in Brazil and is covered with pristine forests, but the region is threatened by dam construction projects. An incomplete mammal biodiversity inventory was conducted in the area during the late 1970s. Here, we present results of sampling from 7,295 live-trap nights, 6,000 pitfall-trap nights, more than 1,200 km of walking transect censuses, and approxi- mately 3,500 camera-trap days, all conducted between 2012 and 2014. These sampling efforts generated a list of 86 known species of nonvolant mammals, making the park the single most species-rich area for nonvolant mammals both in the Amazon Basin and in the Neotropics as a whole. Amazonia National Park is a megadiverse site, as is indicated by its mammalian richness, which includes 15 threatened mammal species and 5 to 12 new species of small mammals. As such, it merits being a high-conservation priority and should be an important focus of Brazilian authorities’ and the international scientific com- munity’s conservation efforts. -

DOUZERY Submitted: 31 March 2012 Fabre, P.-H., Galewski, T., Tilak, M.-k. & Douzery, E.J.P. (2012) Diversification of South Accepted: 15 September 2012 American spiny rats (Echimyidae): a multigene phylogenetic approach. —Zoologica Scripta, doi:10.1111/j.1463-6409.2012.00572.x 42, 117–134. We investigated the phylogenetic relationships of 14 Echimyidae (spiny rats), one Myocas- toridae (nutrias) and one Capromyidae (hutias) genera based on three newly sequenced nuclear genes (APOB, GHR and RBP3) and five previously published markers (the nuclear RAG1 and vWF, and the mitochondrial cytochrome b, 12S rRNA and 16S rRNA). We recovered a well-supported phylogeny within the Echimyidae, although the evolutionary relationships among arboreal echimyid taxa remain unresolved. Molecular divergence times estimated using a Bayesian relaxed molecular clock suggest a Middle Miocene origin for most of the extant echimyid genera. Echimyidae seems to constitute an example of evolu- tionary radiation with high species diversity, yet they exhibit only narrow skull morpholog- ical changes, and the arboreal and terrestrial taxa are shown to retain numerous plesiomorphic features. The most recent common ancestor of spiny rats is inferred to be a ground-dwelling taxon that has subsequently diverged into fossorial, semiaquatic and arbo- real habitats. The arboreal clade polytomy and ancestral character estimations suggest that the colonization of the arboreal niche constituted the keystone event of the echimyid radia- tion. However, biogeographical patterns suggest a strong influence of allopatric speciation in addition to ecology-driven diversification among South American spiny rats. -

Identification of Invasive Alien Species Using DNA Barcodes
Identification of Invasive Alien Species using DNA barcodes Royal Belgian Institute of Natural Sciences Royal Museum for Central Africa Rue Vautier 29, Leuvensesteenweg 13, 1000 Brussels , Belgium 3080 Tervuren, Belgium +32 (0)2 627 41 23 +32 (0)2 769 58 54 General introduction to this factsheet The Barcoding Facility for Organisms and Tissues of Policy Concern (BopCo) aims at developing an expertise forum to facilitate the identification of biological samples of policy concern in Belgium and Europe. The project represents part of the Belgian federal contribution to the European Research Infrastructure Consortium LifeWatch. Non-native species which are being introduced into Europe, whether by accident or deliberately, can be of policy concern since some of them can reproduce and disperse rapidly in a new territory, establish viable populations and even outcompete native species. As a consequence of their presence, natural and managed ecosystems can be disrupted, crops and livestock affected, and vector-borne diseases or parasites might be introduced, impacting human health and socio-economic activities. Non-native species causing such adverse effects are called Invasive Alien Species (IAS). In order to protect native biodiversity and ecosystems, and to mitigate the potential impact on human health and socio-economic activities, the issue of IAS is tackled in Europe by EU Regulation 1143/2014 of the European Parliament and Council. The IAS Regulation provides for a set of measures to be taken across all member states. The list of Invasive Alien Species of Union Concern is regularly updated. In order to implement the proposed actions, however, methods for accurate species identification are required when suspicious biological material is encountered.
