Data from: Plant – herbivorous beetle networks: molecular characterization of trophic ecology within a threatened steppic environment
2015
DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…
Samuel Fernberger's rejected doctoral dissertation: A neglected resource for the history of ape research in America.
2009
I summarize a never-completed 1911 doctoral dissertation on ape behavior by Samuel Fernberger of the University of Pennsylvania. Included are observations on many behavioral patterns including sensory and perceptual function, learning, memory, attention, imagination, personality, and emotion in an orangutan and two chimpanzees. There are examples of behavior resembling insight, conscience, tool use and imitation. Language comprehension was good but speech production was minimal. The document appears to contradict a brief published article on the project by William Furness in that punishment was frequently used. The document is important for understanding Fernberger's early career, for antic…
A novel compound heterozygous mutation in PYGM gene associated with McArdle’s disease
2022
McArdle's disease is an autosomal recessive glycogenosis due to mutation in the myophosphorylase gene (PYGM) resulting in a pure myopathy. The clinical onset typically occurs in childhood with cramps, myalgia, and intolerance to physical exercise, although late onset forms are also reported. We describe a case of a 17-year-old male complaining of cramps and myalgia following brief and intense exercise. The patient reported marked improvement in muscle fatigability few minutes after starting aerobic exercise. When he was a child, he had experienced few episodes of vomiting, nausea, and black colored urine following physical activity. Laboratory testings revealed high creatine kinase serum le…

Phylogenomics of species from four genera of New World monkeys by flow sorting and reciprocal chromosome painting
2007
Abstract Background The taxonomic and phylogenetic relationships of New World monkeys (Platyrrhini) are difficult to distinguish on the basis of morphology and because diagnostic fossils are rare. Recently, molecular data have led to a radical revision of the traditional taxonomy and phylogeny of these primates. Here we examine new hypotheses of platyrrhine evolutionary relationships by reciprocal chromosome painting after chromosome flow sorting of species belonging to four genera of platyrrhines included in the Cebidae family: Callithrix argentata (silvered-marmoset), Cebuella pygmaea (pygmy marmoset), Callimico goeldii (Goeldi's marmoset) and Saimiri sciureus (squirrel monkey). This is t…

Pigmaliòn en Sicilia
2010
By the end of 18th century three performances of “Pygmalion” by Jean-Jacques Rousseau are attested in Sicily, in Palermo (1777, 1797) and in Catania (1791), but every of them gives problems for their confirmation in coeval documents or for some other peculiarity. The most interesting is certainly the Catania's one attested by the libretto printed for the circumstance. There “Pygmalion” was performed in the original form of melodrama, but translated in Italian. The composer indicated on the libretto is Ch. W. Gluck but we can suppose that Gluck's work utilised in Catania, without informing the author, had been written for different purpose and intention. Somebody perhaps organised that perfo…
Younger bank voles are more vulnerable to avian predation
2008
The importance of predation on prey populations is mainly determined by the number of eaten prey. However, the total impact of predation might also be determined by the selection of certain prey individuals, e.g., different sexes or age categories. Here we tested selective predation by an avian predator, the pygmy owl ( Glaucidium passerinum (L., 1758)), on bank voles ( Myodes ( Clethrionomys ) glareolus (Schreber, 1780)). We compared the sex, age, and mass of hoarded prey with the animals snap-trapped from the field. There were no differences in the sex ratio between hoarded bank voles and those available in the field. However, hoarded voles were significantly younger than ones in the fie…
Effect of Willow TitPoecile montanusalarm calls on attack rates by Pygmy OwlsGlaucidium passerinum
2013
One suggested anti-predator function of alarm calls is to deliver a message to a predator that it has been detected. Moreover, giving the alarm call could provide a signal to the predator that capturing the individual giving the alarm is more difficult than capturing its silent group members, as the caller is probably the most aware of the predator's location. In an aviary experiment using stuffed dummy Willow Tits Poecile montanus, we assessed whether an authentic alarm call given by Willow Tit affected Pygmy Owl Glaucidium passerinum prey preference. In the experiment, the Owls attacked only the ‘silent’ dummy individuals, suggesting that alarm calling could offer direct fitness benefits …
