The Genome and Methylome of a Subsocial Small Carpenter Bee, Ceratina calcarata
Understanding the evolution of animal societies, considered to be a major transition in evolution, is a key topic in evolutionary biology. Recently, new gateways for understanding social evolution have opened up due to advances in genomics, allowing for unprecedented opportunities in studying social behavior on a molecular level. In particular, highly eusocial insect species (caste-containing s...
متن کاملHistorical Isolation of the Galápagos Carpenter Bee (Xylocopa darwini) despite Strong Flight Capability and Ecological Amplitude
Colonization across the Galápagos Islands by the carpenter bee (Xylocopa darwini) was reconstructed based on distribution of mitochondrial haplotypes (cytochrome oxidase II (COII) sequences) and haplotype lineages. A total of 12 haplotypes were found in 118 individuals of X. darwini. Distributional, phylogenetic and phylogeographic analyses suggest early colonization of most islands followed by...
متن کاملVisual Adaptations for Mate Detection in the Male Carpenter Bee Xylocopa tenuiscapa
Sexual dimorphism in eye structure is attributed to sexual selection in animals that employ vision for locating mates. In many male insects, large eyes and eye regions of higher acuity are believed to facilitate the location of females. Here, we compare various features of male and female eyes in three sympatric carpenter bee species, which include two diurnal species (Xylocopa tenuiscapa and X...
متن کاملThe carpenter syndrome phenotype.
Carpenter syndrome (Acrocephalopolysyndactyly type II), first described in 1901, consists of acrocephaly, syndactyly, polydactyly, congenital heart disease, mental retardation, hypogenitalism, cryptorchidism, obesity, umbilical hernia and bony abnormalities. We report a 6 years old boy presenting as a union of these malformations and also having bilateral sensorineural hearing loss. Auditory di...
متن کاملBaltimore County , Baltimore
It has been found that listeners with sensorineural hearing loss who show similar patterns of consonant confusions also tend to have similar audiometric profiles. The present study determined whether normal listeners, presented with filtered speech, would produce consonant confusions similar to those previously reported for the hearing-impaired listener. Consonant confusion matrices were obtain...
