Ecological and anthropogenic effects on the genomic diversity of lemurs in Madagascar.

Ecological variation and anthropogenic landscape modification have had key roles in the diversification and extinction of mammals in Madagascar. Lemurs represent a radiation with more than 100 species, constituting roughly one-fifth of the primate order. Almost all species of lemurs are threatened with extinction, but little is known about their genetic diversity and demographic history.

Adulis and the transshipment of baboons during classical antiquity.

Adulis, located on the Red Sea coast in present-day Eritrea, was a bustling trading centre between the first and seventh centuries CE. Several classical geographers-Agatharchides of Cnidus, Pliny the Elder, Strabo-noted the value of Adulis to Greco-Roman Egypt, particularly as an emporium for living animals, including baboons ( spp.).

A global catalog of whole-genome diversity from 233 primate species.

The rich diversity of morphology and behavior displayed across primate species provides an informative context in which to study the impact of genomic diversity on fundamental biological processes. Analysis of that diversity provides insight into long-standing questions in evolutionary and conservation biology and is urgent given severe threats these species are facing. Here, we present high-coverage whole-genome data from 233 primate species representing 86% of genera and all 16 families.

The landscape of tolerated genetic variation in humans and primates.

Personalized genome sequencing has revealed millions of genetic differences between individuals, but our understanding of their clinical relevance remains largely incomplete. To systematically decipher the effects of human genetic variants, we obtained whole-genome sequencing data for 809 individuals from 233 primate species and identified 4.3 million common protein-altering variants with orthologs in humans.

DRD4 allele frequencies in greylag geese vary between urban and rural sites.

With the increasing urbanization of the last decades, more and more bird species occur in urban habitats. Birds which thrive in urban habitats often have a higher tolerance toward human disturbance and show behaviors which differ from their rural counterparts. There is increasing evidence that many behaviors have a genetic basis.

A stable lanthanum hydroxamate metal-organic framework with radical character and electrical conductivity.

Metal-organic frameworks with hydroxamate linkers are an emerging new class of stable porous crystalline materials. Due to the difficulty in controlling reversible formation of strong metal-hydroxamate bonds and the limitation of available hydroxamate ligands, hydroxamate MOFs are rarely reported and their applications are underexplored. Herein, we report on a lanthanum MOF, La-ONDI, containing the redox-active hydroxamate ligand ONDI.

Small, odd and old: The mysterious is the most basal Sulawesi tarsier.

In this study, we present the first genetic evidence of the phylogenetic position of the mountain tarsier of Sulawesi, Indonesia This mysterious primate is the only Eastern tarsier species that occurs exclusively in cloud forests above 1800 m.a.s.

Tetracyclines improve experimental lymphatic filariasis pathology by disrupting interleukin-4 receptor-mediated lymphangiogenesis.

Lymphatic filariasis is the major global cause of nonhereditary lymphedema. We demonstrate that the filarial nematode Brugia malayi induced lymphatic remodeling and impaired lymphatic drainage following parasitism of limb lymphatics in a mouse model. Lymphatic insufficiency was associated with elevated circulating lymphangiogenic mediators, including vascular endothelial growth factor C.

Population genetics of the European rabbit along a rural-to-urban gradient.

The European rabbit (Oryctolagus cuniculus) is declining in large parts of Europe but populations in some German cities remained so far unaffected by this decline. The question arises of how urbanization affects patterns of population genetic variation and differentiation in German rabbit populations, as urban habitat fragmentation may result in altered meta-population dynamics. To address this question, we used microsatellite markers to genotype rabbit populations occurring along a rural-to-urban gradient in and around the city of Frankfurt, Germany.

Can a temporary bond between dye and redox mediator increase the efficiency of p-type dye-sensitized solar cells?

Efficient n-type dye-sensitized solar cells are known since the seminal work of O'Reagan and Grätzel in 1991. However, highly efficient p-type dye-sensitized solar cells have not been developed so far. This hinders the construction of tandem dye-sensitized solar cells, which can surpass the performance of n-type devices.

The pioneering role of PRDM9 indel mutations in tarsier evolution.

PRDM9 is currently the sole speciation gene found in vertebrates causing hybrid sterility probably due to incompatible alleles. Its role in defining the double strand break loci during the meiotic prophase I is crucial for proper chromosome segregation. Therefore, the rapid turnover of the loci determining zinc finger array seems to be causative for incompatibilities.

Importance of latrine communication in European rabbits shifts along a rural-to-urban gradient.

Background: Information transfer in mammalian communication networks is often based on the deposition of excreta in latrines. Depending on the intended receiver(s), latrines are either formed at territorial boundaries (between-group communication) or in core areas of home ranges (within-group communication). The relative importance of both types of marking behavior should depend, amongst other factors, on population densities and social group sizes, which tend to differ between urban and rural wildlife populations.

Stop and Go - Waves of Tarsier Dispersal Mirror the Genesis of Sulawesi Island.

The Indonesian island of Sulawesi harbors a highly endemic and diverse fauna sparking fascination since long before Wallace's contemplation of biogeographical patterns in the region. Allopatric diversification driven by geological or climatic processes has been identified as the main mechanism shaping present faunal distribution on the island. There is both consensus and conflict among range patterns of terrestrial species pointing to the different effects of vicariant events on once co-distributed taxa.

Control region length dynamics potentially drives amino acid evolution in tarsier mitochondrial genomes.

Patterns and processes of molecular evolution critically influence inferences in phylogeny and phylogeography. Within primates, a shift in evolutionary rates has been identified as the rationale for contrasting findings from mitochondrial and nuclear DNA studies as to the position of Tarsius. While the latter now seems settled, we sequenced complete mitochondrial genomes of three Sulawesi tarsiers (Tarsius dentatus, T.

The IgE gene in primates exhibits extraordinary evolutionary diversity.

Membrane-bound IgE (mIgE) on B lymphocytes is essential for IgE production. Earlier studies showed that the ε chain of mIgE (mε) on human B cells has a "long" isoform, with an extra "CεmX" domain of 52 amino acid (aa) residues between the CH4 domain and the membrane-anchor segment, as compared to the conventional "short" isoform. Because CεmX provides an antigenic site for targeting IgE-expressing B cells to down-regulate IgE production in patients with allergy, analysis of CεmX in various animals is of great interest.

Elucidating geological and biological processes underlying the diversification of Sulawesi tarsiers.

Because of their exceptionally long independent evolution, a range diminution of their Eocene relatives, and a remarkable subsequent diversification in Southeast Asia, tarsiers are of particular importance to evolutionary primatologists. Little is known, however, on the processes shaping the radiation of these small enigmatic primates-especially on the Indonesian island of Sulawesi, their center of endemism. Geological reconstructions and progress in applying DNA sequence information to divergence dating now provide us with the tools and background to comprehend tarsier dispersal.

The tick fauna of Sulawesi, Indonesia (Acari: Ixodoidea: Argasidae and Ixodidae).

Twenty-six species of ticks are reported from the island of Sulawesi (Celebes), Indonesia. These include two species of soft ticks (Argasidae), Carios batuensis and C. vespertilionis, and the following 24 species of hard ticks (Ixodidae): Amblyomma babirussae, A.

Habitat use analysis of Dian's tarsier (Tarsius dianae) in a mixed-species plantation in Sulawesi, Indonesia.

To investigate the importance of mixed-species plantations as a potential habitat for small arboreal primates, we radio-tracked six Dian's tarsiers (Tarsius dianae) in such an area in Central Sulawesi, Indonesia, and explored their selectivity for certain vegetation types. The animals strongly favored sporadic dense shrubbery over more open structures, yet they also utilized cash-crop cultivations for hunting insects. This paper documents the first habitat use analysis of tarsiers on agricultural land and exemplifies the vital role of mixed-species plantations in conserving wildlife when nearby forest is logged.

Habitat-specific ranging patterns of Dian's tarsiers (Tarsius dianae) as revealed by radiotracking.

Dian's tarsier Tarsius dianae, one of the smallest primates on earth, is endemic to the central regions of Sulawesi, Indonesia. To evaluate the effects of increasing land use by humans on the ranging patterns of this nocturnal insect hunter, four study plots along a gradient of anthropogenic disturbance were selected for this study. In these plots, 71 tarsiers were captured with mist nets, and 30 of these were fitted with 3.
