Phylogenetic relationships of the Italian populations of Horseshoe Whip Snake Hemorrhois hippocrepis (Serpentes, Colubridae)
2020
Hemorrhois hippocrepis is a colubrid snake with a West Mediterranean distribution. It is widespread in the Iberian Peninsula and Northwest Africa. The only Italian populations are found on the islands of Sardinia and Pantelleria. The phylogenetic relationships of these insular populations have been analysed for the first time on the basis of the mitochondrial DNA cytochrome b gene. The sequences were compared with those available from the geographic range of this species. The analyses showed that the Italian samples are part of a lineage that groups Tunisian and East Algerian samples, with which they share the same haplotype. These results strongly support the hypothesis of a recent origin …
The Horseshoe whip snake (Hemorrhois hippocrepis) on Ibiza: predator release in an invasive population
2020
Abstract The key to fighting a biological invasion may lie in understanding every variable that can explain its success. The Enemy Release Hypothesis (ERH) states that when an invader arrives to a new environment, the absence of its common enemies (predators, parasites and competitors) facilitates the invasion success. The Horseshoe whip snake (Hemorrhois hippocrepis) has been recently introduced from the Iberian Peninsula to the island of Ibiza, and it is currently threatening the only endemic vertebrate, the Ibiza wall lizard (Podarcis pityusensis). We hypothesized that the snake invasion success is caused by the absence of natural predators, and we checked the ERH by relating the tail br…
Learning to Read Equine Agency: Sense and Sensitivity at the Intersection of Scientific, Tacit and Situated Knowledges
2021
The aim of this essay is to address the challenges and problems in communicating with horses and interpreting their communication in everyday handling and training situations. We seek ways to learn more about equine communication and agency in the prevention of cruelty against animals and in enhancing animal welfare. We ask how it would be possible to learn to read the subtle signs of equine communication and agency in a sensible, sensitive, and ethical way to increase the health and wellbeing of horses that humans interact with. We have placed this theoretical examination in a multidisciplinary framework that consists of humananimal studies, feminist posthumanities, cultural and literary s…
Chromogranin A in the Mammalian Merkel Cell: Cellular and Subcellular Distribution
1989
Chromogranin-A (CGA), which accounts for more than half the soluble matrix protein in secretory granules of various neuroendocrine cells, has a wide spectrum of potential biological roles and is considered an important marker of the diffuse neuroendocrine system (DNES). Light and electron microscopic immunohistochemistry of mammalian skin revealed that Merkel cells are exclusively CGA-immunoreactive (ir) and that the immunoreaction is localized in the secretory granules. This finding supports the classification of the Merkel cell as a member of the DNES. The CGA immunoreactivity was restricted to Merkel cells of pigs and humans. In human embryonic skin, CGA was expressed in Merkel cells as …
Interrelationship between reproductive hormones and acute phase proteins during estrous cycle and pregnancy in Spanish purebred broodmares
2021
Highlights • Steroid hormones and acute phase proteins in cyclic and pregnant mares were evaluated. • SAA and CRP did not discriminate cyclic and pregnant mares. • Pregnancy induced a limited acute phase response in Spanish purebred mares. • SAA, Hp and CRP were independent of E1 and P4 dynamics during pregnancy.
La estatua marmórea del duque de Lerma en el castillo de Dénia, obra de Giuseppe Carlone
2018
On the 28th of August of 1612, Juan Vivas de Canamas, the ambassador of king Philip III in Genoa, commissioned the Genoese sculptor Giuseppe Carlone to carve a large statue made of Polveracio white marble representing, according to the drawing attached to the contract, the figure of a knight. The portrait depicts none other than the Duke of Lerma, whose marble effigy was intended to preside in his castle and palace of the Valencian city of Denia and was installed there at the end of 1613. In this sense, the work is historically framed in the process of renovation of the castle that Lerma began at the end of the 16th century and that included the incorporation of this exclusive artistic comm…
Technological aspects of horse meat products – A review
2017
Abstract Horse meat and its products can be considered as a food with a high nutritional value. However, due to cases of economically motivated food adulteration by the intentional addition of horse meat beef products in recent years, horse meat has become a controversial issue. Consumer confidence in meat products and the meat industry has diminished, although consumers consider the differences between the food content and the label as the major issue rather than the safety and nutritional characteristics of horse meat. The elaboration of meat products from horse meat (e.g. “cecina”, dry-cured loin, salami, bressaola and pâte) is also an interesting alternative to other traditional meat pr…
Revisional Notes on Trictenotoma Gray, 1832 (Coleoptera: Trictenotomidae) in Indochina Bioregion, with Description of a New Species
2020
A review and species key to TrictenotomaGray, 1832 (Trictenotomidae Blanchard, 1845) from the Indochina bioregion, mainland Southeast Asia, is presented for the first time. Adults of Trictenotoma childreniGray, 1832, T. davidi Deyrolle, 1875 and T. mouhoti Deyrolle, 1875 are redescribed. Trictenotoma pollockisp. nov. from southern Vietnam is described and illustrated. A lectotype is designated for T. mouhoti Deyrolle, 1875.
Projections from the medial cortex in the brain of lizards: correlation of anterograde and retrograde transport of horseradish peroxidase with Timm s…
1988
Efferent projections of the medial cortex of the lizards Podarcis hispanica and Gallotia stehlinii were studied by examining the transport of horseradish peroxidase; results were correlated with those from Timm-stained sections. Two efferent systems were found. The first reaches the distal part of the outer plexiform layer in the medial, dorsomedial, and dorsal cortices, i.e., zones that are negative to Timm staining, and possibly originates from horizontal fusiform neurons. The second reaches the Timm-positive zones in the cortex and septum and is topographically arranged: the vertical portion of the intermediate and caudal medial cortex and the entire rostral medial cortex project to the …
Genetic Diversity of White Clover (Trifolium Repens L.) from the Urban Area of Rīga Baltā Āboliņa (Trifolium Repens L.) Ģenētiskā Daudzveidība Rīgas …
2015
Baltais āboliņš (Trifolium repens L.) ir tauriņziežu dzimtas augs, plaši izplatīts gan pilsētvidē, gan ārpus tās. Tas tiek izmantots kā lauksaimniecības augs biomasas iegūšanai, un tā ir arī populāra daudzgadīgos zālienus veidojošā suga - pilsētvidē balto āboliņu sēj zālājos. Baltais āboliņš plaši pārstāvēts dažādos biotopos ar mainīgu ārējo faktoru ietekmi, tai skaitā pilsētvidē. Tādēļ tas ir piemērots modeļobjekts antropogēnās ietekmes pētīšanai. Darba mērķis bija noteikt baltā āboliņa Latvijas populācijas ģenētisko daudzveidību, izmantojot iPBS (inter primer binding sites) - uz retrotranspazoniem balstītu metodi. Iegūtie rezultāti salīdzināti starp trim augu paraugkopām: pilsētvidē augoš…
