A review of Australian fossil penguins (Aves: Sphenisciformes). Memoirs of Museum Victoria 69: 309–325. Australian fossil penguins (Sphenisciformes) are reviewed as a basis for future primary research. The five named species are based on type specimens of Eocene, Miocene—Pliocene and Holocene age collected from South Australia, Victoria and Tasmania. The phylogenetic affinities of these taxa remain unresolved. Only one type specimen is represented by clearly associated elements of a skeleton; the rest are single bones (isolated partial humeri and a pelvis). Further research is required to establish the taxonomic status of Pachydyptes simpsoni, Anthropodyptes gilli, Pseudaptenodyes macraei, ?Pseudaptenodytes minor and Tasidyptes hunteri. Additional described specimens include isolated postcranial elements from the Late Oligocene of South Australia and Late Miocene—Early Pliocene of Victoria. Other Miocene and Pliocene -

Original artwork by Jacob Blokland. i ACKNOWLEDGEMENTS The last couple years have been exciting and challenging. It has been a pleasure to work with great people, and be involved with new research that will hopefully be of contribution to science. First of all, I would like to thank my two supervisors, Dr Catherine Reid and Dr Paul Scofield, for tirelessly reviewing my work and providing feedback. I literally could not have done it without you, and your time, patience and efforts are very much appreciated. Thank you for providing me with the opportunity to do a vertebrate palaeontology based thesis. I would like to extend my deepest gratitude to Catherine for encouragement regarding my interest in palaeontology since before I was an undergraduate, and providing great information regarding thesis and scientific format. I am also extremely grateful to Paul for welcoming me to use specimens from Canterbury Museum, and providing useful information and recommendations for this project through your expertise in this particular discipline. I would also like to thank Associate Professor Jeffrey Stilwell for collecting the fossil specimens used in this thesis, and for the information you passed on regarding the details of the fossils. Thank you to Geoffrey Guinard for allowing me to use your data from your published research in this study. -

Phylogenetic Characters in the Humerus and Tarsometatarsus of Penguins
vol. 35, no. 3, pp. 469–496, 2014 doi: 10.2478/popore−2014−0025 Phylogenetic characters in the humerus and tarsometatarsus of penguins Martín CHÁVEZ HOFFMEISTER School of Earth Sciences, University of Bristol, Wills Memorial Building, Queens Road, BS8 1RJ, Bristol, United Kingdom and Laboratorio de Paleoecología, Instituto de Ciencias Ambientales y Evolutivas, Universidad Austral de Chile, Valdivia, Chile <[email protected]> Abstract: The present review aims to improve the scope and coverage of the phylogenetic matrices currently in use, as well as explore some aspects of the relationships among Paleogene penguins, using two key skeletal elements, the humerus and tarsometatarsus. These bones are extremely important for phylogenetic analyses based on fossils because they are commonly found solid specimens, often selected as holo− and paratypes of fossil taxa. The resulting dataset includes 25 new characters, making a total of 75 characters, along with eight previously uncoded taxa for a total of 48. The incorporation and analysis of this corrected subset of morphological characters raise some interesting questions consider− ing the relationships among Paleogene penguins, particularly regarding the possible exis− tence of two separate clades including Palaeeudyptes and Paraptenodytes, the monophyly of Platydyptes and Paraptenodytes, and the position of Anthropornis. Additionally, Noto− dyptes wimani is here recovered in the same collapsed node as Archaeospheniscus and not within Delphinornis, as in former analyses. Key words: Sphenisciformes, limb bones, phylogenetic analysis, parsimony method, revised dataset. Introduction Since the work of O’Hara (1986), the phylogeny of penguins has been a sub− ject of great interest. During the last decade, several authors have explored the use of molecular (e.g., Subramanian et al. -

Viewed 225 People (15 from Each Island)
Łuczaj et al. Journal of Ethnobiology and Ethnomedicine (2019) 15:18 https://doi.org/10.1186/s13002-019-0297-0 RESEARCH Open Access The ethnobotany and biogeography of wild vegetables in the Adriatic islands Łukasz Łuczaj1* , Marija Jug-Dujaković2, Katija Dolina3, Mirjana Jeričević4 and Ivana Vitasović-Kosić5 Abstract Background: Archipelagos of islands have played an important role in shaping some of the paradigms of biology, including the theory of the evolution of species. Later, their importance in biology was further emphasised by the theory of island biogeography, which contributed to a better understanding of the shaping of species richness not only on real islands, but on isolated habitat islands as well. Although ethnobotany is a well-established discipline, patterns of knowledge about plant uses in archipelagos have never been quantitatively analysed, and the whole concept has been only briefly mentioned in the ethnobiological context. The aim of our study was to record which taxa of wild vegetables have been consumed in the Adriatic islands and to establish if such variables as island size, population size, flora or its isolation are correlated with the number of wild vegetables used. Methods: We interviewed 225 people (15 from each island). Results: Altogether, the use of 89 species of wild vegetables has been recorded. The largest number of wild vegetables is eaten on the islands of Korčula, Vis and Šolta, and the lowest on Ugljan, Cres and Dugi Otok. The studied independent variables had a small and statistically not significant effect on the wild vegetable list length. The most visible effect was an increasing trend from north-west to south-east, overrunning the typical biogeographical island patterns. -
Conservation Assessment of Some Rare and Endemic Crepis (Asteraceae) Taxa in Turkey
Nature Conservation Research. Заповедная наука 2019. 4(3): 117–123 https://dx.doi.org/10.24189/ncr.2019.056 CONSERVATION ASSESSMENT OF SOME RARE AND ENDEMIC CREPIS (ASTERACEAE) TAXA IN TURKEY Huseyin Inceer*, Nursen Aksu Kalmuk Karadeniz Technical University, Turkey *e-mail: [email protected] Received: 29.05.2019. Revised: 12.07.2019. Accepted: 01.08.2019. Red Listing is a valuable tool for raising the awareness about those taxa which face the risk of extinction. It is the first step towards highlighting the problem of species decline and loss, as well as encouraging policy makers. In this study, a new or revised threatened status of five rare and two endemicCrepis taxa from Turkey������������� were present� ed, based upon IUCN red list categories and criteria. The following taxa are analysed: Crepis amanica, C. aurea subsp. olympica, C. bithynica, C. dioscoridis, C. foetida subsp. glandulosa, C. rubra, and C. syriaca. The area of occupancy (AOO) has been calculated for each taxon using the software GeoCAT (Geospatial Conservation Assessment Tool) �����������������and according to �2 × 2 � ����������������� km grid cell si������������������������������������������������e. A distribution map has been drawn with ArcGI����� ver� sion 10.3. Current IUCN red list categories and criteria were used to assess the conservation status of the taxa. New field observations and the population si�es were presented for each taxon. The taxa were placed into the group of critically endangered or endangered because of their small geographical distribution, narrow habitat specificity and non�abundant within the territory of Turkey. Based on the IUCN categorisation, our results show that all the taxa studied are directly and/or indirectly threatened by human activities, such as tourism, agriculture, gra�ing, pollution or urbanisation and competition with woody or invasive plants. -

We collected the minibuses, and were soon on the road, heading east across Italy, noting the groves of Walnuts (Juglans regia) and Hazels (Corylus avellana), which gave way to arable and pasture. Some group members noted their first of many orchids, with large spikes of Lady Orchid (Orchis purpurea) on the verges. Leaving the autostrada, our route took us past some muddy pools where Black-winged Stilts, Little Egrets and Spoonbills made a good start to the bird list. Passing Manfredonia, we climbed slowly up to Monte St Angelo, high on the Gargano massif, and arrived in good time to settle into our hotel before dinner.
