Limestone cliff - face and cave use by wild ring-tailed lemurs (Lemur catta) in southwestern Madagascar
Ring - tailed lemurs live in a range of habitats in southwestern Madagascar. To date, much of the knowledge of ring - tailed lemur ecology, biology and behavior come from riverine gallery forests sites. Recent years have seen an expansion of comprehensive research on this resilient species, including areas of limestone spiny forest along Madagascar’s southwestern coast. This work is documenting newly discovered behaviors by this species. The regular use of cliff - faces and embedded crevices and caves by ring - tailed lemurs in southwestern Madagascar are reported here. Cave use by several anthropoid primates has been explained as a thermoregulatory behavior. It is suggested that cliff - face and cave use by these ring-tailed lemurs serves several purposes, including resource acquisition, thermoregulation, and as an anti - predator avoidance strategy in the absence of suitable large sleeping trees. Observations indicate that the limestone boundaries of the Mahafaly Plateau and their associated xerophytic scrub forests warrant further conservation attention, given the presence of behavioral variation and increasing threats to this endangered primate species
Redescription of Lemuricola (Madoxyuris) bauchoti (Nematoda, Oxyuridae) from Lemur catta in Madagascar
Lemuricola (Madoxyuris) bauchoti Chabaud, Brygoo et Petter, 1965 is redescribed from material collected from the ring-tailed lemur, Lemur catta, from the Beza Mahafaly Special Reserve in Madagascar using the scanning electron microscope. This is a new host record and the first oxyurid reported from the ring-tailed lemur. Previously, records of each species of the subgenus Madoxyuris have been restricted to a single host species, but the close relationship between these nematodes and their Strepsirrhini hosts will only be proven when additional records fill in the gaps in their distribution.Centro de Estudios ParasitolĂłgicos y de Vectore
BERITA ANTASARI DI KOMPAS DAN CITRA KPK
Criminalization of the Komisi Pemberantasan Korupsi (KPK) began with
the Antasari Azhar who stuck a murder case, the preaching of the Antasari can
change perceptions about the task, status, organization, powers and
responsibilities of the KPK. This can cause a wide gap between the demands and
expectations of the quality of the image KPK KPK in the news media.
The newspaper is a media that provides complete information than other
media. Discussions sharply news and interesting ideas are always written in the
newspaper. News Antasari is one of the interesting news and shake your body
warm because the KPK is shown as much as 24 times the headlines by the
newspaper Kompas in which, in preaching about Antasari Azhar case involved a
murder case, biography Antasari in handling various cases of corrupt law and also
information about our Commission as guidance as and protector of society. The
purpose of this study is to describe student perceptions of member Badan
Eksekutif Mahasiswa (BEM) Faculty of Law University of Sebelas Maret
surakarta on the image of the KPK after using the daily newspaper Kompas on
news Antasari in May - June 2009
This study uses an explanatory type of research that describes the
relationship between variables by testing the hypothesis that has been previously
formulated. Respondents in this study represents the total number of student
members of BEM Faculty of Law which is still active in the BEM Faculty of Law,
Sebelas Maret University and read about the news Antasari. In a study using the
technique of this censusas many as 40 people found the respondent. While the
analysis used to test cross-tabulation correlation formula
From the cross tabulation test results,showed a significant relationship
between use of the Kompas daily newspaper with students' perceptions on the
image of KPK. and showed a significant relationship between external factors
that include social groups and other mass media's role in students' perceptions on
the image of the KPK after using Antasari news in Kompas

Use of Mangroves by Lemurs
Despite an increasing recognition of the ecosystem services provided by mangroves, we know little about their role in maintaining terrestrial biodiversity, including primates. Madagascar’s lemurs are a top global conservation priority with 94 % of species threatened with extinction, but records of their occurrence in mangroves are scarce. I used a mixed-methods approach to collect published and unpublished observations of lemurs in mangroves: I carried out a systematic literature search, and supplemented this with a targeted information request to 1243 researchers, conservation and tourism professionals and others who may have visited mangroves in Madagascar. I found references to, or observations of, at least 23 species in five families using mangroves, representing more than 20 % of lemur species and over 50 % of species whose distributions include mangrove areas. Lemurs used mangroves for foraging, sleeping and travelling between terrestrial forest patches, and some were observed as much as 3 km from the nearest permanently dry land. However most records were anecdotal and thus tell us little about lemur ecology in this habitat. Mangroves are more widely used by lemurs than has previously been recognised, and merit greater attention from primate researchers and conservationists in Madagascar
Factors influencing terrestriality in primates of the Americas and Madagascar
Among mammals, the order Primates is exceptional in having a high taxonomic richness in which the taxa are arboreal, semiterrestrial, or terrestrial. Although habitual terrestriality is pervasive among the apes and African and Asian monkeys (catarrhines), it is largely absent among monkeys of the Americas (platyrrhines), as well as galagos, lemurs, and lorises (strepsirrhines), which are mostly arboreal. Numerous ecological drivers and species-specific factors are suggested to set the conditions for an evolutionary shift from arboreality to terrestriality, and current environmental conditions may provide analogous scenarios to those transitional periods. Therefore, we investigated predominantly arboreal, diurnal primate genera from the Americas and Madagascar that lack fully terrestrial taxa, to determine whether ecological drivers (habitat canopy cover, predation risk, maximum temperature, precipitation, primate species richness, human population density, and distance to roads) or species-specific traits (bodymass, group size, and degree of frugivory) associate with increased terrestriality. We collated 150,961 observation hours across 2,227 months from 47 species at 20 sites in Madagascar and 48 sites in the Americas. Multiple factors were associated with ground use in these otherwise arboreal species, including increased temperature, a decrease in canopy cover, a dietary shift away from frugivory, and larger group size. These factors mostly explain intraspecific differences in terrestriality. As humanity modifies habitats and causes climate change, our results suggest that species already inhabiting hot, sparsely canopied sites, and exhibiting more generalized diets, are more likely to shift toward greater ground use
