Trees are sparse and low scrub is the predominant vegetation. – It’s part of the national parks system of Italy, in 2002 the island was converted to a wildlife and marine preserve. – In 1885 the island became a Lazaretto and an agricultural penal colony (till 1998). About 100 families of Sardinian farmers and Genoese fishermen who lived on Asinara were obliged to move to Sardinia, where they founded the village of Stintino. Asino dell’Asinara (Asinara Donkey) Origins: - Uncertain but oral records report the presence of white donkeys on the island since the end of XIX century. - the appearance of the white coat in more recent times is probably due to a random mutation that spread to all the population. Morphology: it is small and the size is similar to the Sardinian donkey; the most important difference is the white coat, that probably belongs to a form of incomplete albinism .

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The study of leeches from Lake Gusinoe and its adjacent area offered us the possibility to determine species diversity. Asa result, an updated species list of the Gusinoe Hirudinea fauna (Annelida, Clitellata) has been compiled. There are two orders and three families of leeches in the Gusinoe area: order Rhynchobdellida (families Glossiphoniidae and Piscicolidae) and order Arhynchobdellida (family Erpobdellidae). In total, 6 leech species belonging to 6 genera have been identified. Of these, 3 taxa belonging to the family Glossiphoniidae (Alboglossiphonia heteroclita f. papillosa, Hemiclepsis marginata,andHelobdella stagnalis) and representatives of 3 unidentified species (Glossiphonia sp., Piscicola sp., and Erpobdella sp.) have been recorded. The checklist gives a contemporary overview of the species composition of leeches and information on their hosts or substrates.

Box 94766, 1090 GT Amsterdam, The Netherlands cBamfield Marine Sciences Centre, Bamfield, British Columbia, Canada, V0R 1B0 Received 19 December 2005; accepted 2 June 2006 Abstract Phylogenetic relationships of (19) serpulid taxa (including Spirorbinae) were reconstructed based on 18S rRNA gene sequence data. Maximum likelihood, Bayesian inference, and maximum parsimony methods were used in phylogenetic reconstruction. Regardless of the method used, monophyly of Serpulidae is confirmed and four monophyletic, well- supported major clades are recovered: the Spirorbinae and three groups hitherto referred to as the Protula-, Serpula-, and Pomatoceros-group. Contrary to the taxonomic literature and the hypothesis of opercular evolution, the Protula- clade contains non-operculate (Protula, Salmacina) and operculate taxa both with pinnulate and non-pinnulate peduncle (Filograna vs. Vermiliopsis), and most likely is the sister group to Spirorbinae. Operculate Serpulinae and poorly or non-operculate Filograninae are paraphyletic. It is likely that lack of opercula in some serpulid genera is not a plesiomorphic character state, but reflects a special adaptation. r 2007 Gesellschaft fu¨r Biologische Systematik.

  • Biomineralization of Polychaete Annelids in the Fossil Record
    minerals Review Biomineralization of Polychaete Annelids in the Fossil Record Olev Vinn Department of Geology, University of Tartu, Ravila 14A, 50411 Tartu, Estonia; [email protected]; Tel.: +372-5067728 Received: 31 August 2020; Accepted: 25 September 2020; Published: 29 September 2020 Abstract: Ten distinct microstructures occur in fossil serpulids and serpulid tubes can contain several layers with different microstructures. Diversity and complexity of serpulid skeletal structures has greatly increased throughout their evolution. In general, Cenozoic serpulid skeletal structures are better preserved than Mesozoic ones. The first complex serpulid microstructures comparable to those of complex structures of molluscs appeared in the Eocene. The evolution of serpulid tube microstructures can be explained by the importance of calcareous tubes for serpulids as protection against predators and environmental disturbances. Both fossil cirratulids and sabellids are single layered and have only spherulitic prismatic tube microstructures. Microstructures of sabellids and cirratulids have not evolved since the appearance of calcareous species in the Jurassic and Oligocene, respectively. The lack of evolution in sabellids and cirratulids may result from the unimportance of biomineralization for these groups as only few species of sabellids and cirratulids have ever built calcareous tubes. Keywords: biominerals; calcite; aragonite; skeletal structures; serpulids; sabellids; cirratulids; evolution 1. Introduction Among polychaete annelids, calcareous tubes are known in serpulids, cirratulids and sabellids [1–3]. The earliest serpulids and sabellids are known from the Permian [4], and cirratulids from the Oligocene [5]. Only serpulids dwell exclusively within calcareous tubes. Polychaete annelids build their tubes from calcite, aragonite or a mixture of both polymorphs. Calcareous polychaete tubes possess a variety of ultrastructural fabrics, from simple to complex, some being unique to annelids [1].

  • Seasearch North Wales 2019 Summary Report
    Seasearch North Wales 2019 Summary Report Report prepared by Lucy Kay, Seasearch Tutor Seasearch Gogledd Cymru 2019 Cynllun gwirfoddol sy’n arolygu rhywogaethau a chynefinoedd morol yw Seasearch ar gyfer deifwyr sy’n deifio yn eu hamser hamdden ym Mhrydain ac Iwerddon. Mae’r cynllun yn cael ei gydlynu yn genedlaethol gan y Gymdeithas Cadwraeth Forol. Mae’r adroddiad hwn yn crynhoi gweithgareddau Seasearch yng Ngogledd Cymru yn ystod 2019. Mae’n cynnwys crynodebau o’r safleoedd a arolygwyd ac yn nodi rhywogaethau a chynefinoedd prin neu anghyffredin a welwyd. Mae’r rhain yn cynnwys nifer o gynefinoedd a rhywogaethau â blaenoriaeth yng Nghymru. Nid yw’r adroddiad hwn yn cynnwys yr holl fanylion data gan fod y rhain wedi eu cofnodi yn y gronfa ddata Marine Recorder a gyflwynwyd i Cyfoeth Naturiol Cymru i’w defnyddio yn ei weithgareddau cadwraeth forol. Mae’r data rhywogaethau hefyd ar gael ar-lein drwy Rwydwaith Bioamrywiaeth Cenedlaethol Atlas. Yn ystod 2019, roedd Seasearch yng Ngogledd Cymru yn parhau i ganolbwyntio ar rywogaethau a chynefinoedd â blaenoriaeth yn ogystal â chasglu gwybodaeth am wely’r môr a bywyd morol ar gyfer safleoedd nad oeddent wedi cael eu harolygu yn flaenorol. Mae’r data o Ogledd Cymru yn 2019 yn cynnwys 15 o Ffurflenni Arolygu a 34 o Ffurflenni Arsylwi, sef 49 ffurflen i gyd. Yn 2019 cyflawnwyd gwaith Seasearch yng Ngogledd Cymru gan Holly Date, cydlynydd rhanbarthol Seasearch yng Ngogledd Cymru; mae ardal Seasearch Gogledd Cymru yn ymestyn o Aberystwyth i Afon Dyfrdwy. Mae’r cydlynydd yn cael ei gynorthwyo gan nifer o Diwtoriaid gweithredol Seasearch, Tiwtoriaid Cynorthwyol a Threfnwyr Deifio.
