The fossil sirenian material from the upper Oligocene Linz Sands of Upper Austria is reviewed and re-described in detail following a recent approach on the invalidity of the genus Halitherium Kaup, 1838. This morphological study provides the fi rst evidence for the synonymy of “Halitherium” cristolii Fitzinger 1842, “H.” abeli Spillmann, 1959 and “H.” pergense (Toula, 1899), supporting the hypothesis that only a single species inhabited the late Oligocene shores of present-day Upper Austria. -

Geodiversitas 35 (4): 815-940. http://dx.doi.org/g2013n4a5 ABSTRACT e newly discovered Upper Miocene to Upper Pliocene San Gregorio assem- blage of the Purisima Formation in Central California has yielded a diverse collection of 34 marine vertebrate taxa, including eight sharks, two bony fish, three marine birds (described in a previous study), and 21 marine mammals. Pinnipeds include the walrus Dusignathus sp., cf. D. seftoni, the fur seal Cal- lorhinus sp., cf. C. gilmorei, and indeterminate otariid bones. Baleen whales include dwarf mysticetes (Herpetocetus bramblei Whitmore & Barnes, 2008, Herpetocetus sp.), two right whales (cf. Eubalaena sp. 1, cf. Eubalaena sp. 2), at least three balaenopterids (“Balaenoptera” cortesi “var.” portisi Sacco, 1890, cf. Balaenoptera, Balaenopteridae gen. et sp. indet.) and a new species of rorqual (Balaenoptera bertae n. sp.) that exhibits a number of derived features that place it within the genus Balaenoptera. is new species of Balaenoptera is relatively small (estimated 61 cm bizygomatic width) and exhibits a comparatively nar- row vertex, an obliquely (but precipitously) sloping frontal adjacent to vertex, anteriorly directed and short zygomatic processes, and squamosal creases. -

Rice-Fields. the Relevance of Cyanobacteria in the Ecosystem
Limnetica 23(1-2) 11/10/04 10:15 Página 95 95 A shallow water ecosystem: rice-fields. The relevance of cyanobacteria in the ecosystem. Eduardo Fernández-Valiente* and Antonio Quesada Departamento de Biología. Universidad Autónoma de Madrid, E-28049 Madrid, Spain * Corresponding author, tel: 34-914978186, fax: 34-914978344, email: [email protected] ABSTRACT In this paper we review the knowledge of the ecology of the largest freshwater ecosystem on Earth: the rice-fields, and in particular the rice-fields from Valencia (Spain) making a special consideration to the cyanobacteria present in this ecosystem. Rice-fields are artificial shallow aquatic ecosystems in which the land management and the agricultural practices together with the rice plant growth govern the major environmental variables affecting the aquatic biota and its relationships. Primary producers are dominated typically by macrophytic algae as Chara and cyanobacteria, both planktonic and benthic (beside the rice plants). Most rice-fields can be considered nutrient replete, since the fertilization inputs and the low ratio volume/surface make that main nutrients are typically available. Under these circumstances other environmental variables as photosynthetically active radiation availability or filtration rates and predation may explain the growth limitation of primary producers. Irradiance availability identify two periods within the cultivation cycle: when plants are short, irradiance is not limiting and some water chemistry variables (as pH, oxygen and dissolved inorganic C concentrations) change drastically as a function of the primary production; when plants are large and the canopy is intense, then irradiance is limiting and the water chemistry changes only slightly along the day. -

APPENDIX 4. Classification and Synonymy of the Sirenia and Desmostylia
revised 3/29/2010 APPENDIX 4. Classification and Synonymy of the Sirenia and Desmostylia The following compilation encapsulates the nomenclatural history of the Sirenia and Desmostylia as comprehensively as I have been able to trace it. Included are all known formal names of taxa and their synonyms and variant combinations, with abbreviated citations of the references where these first appeared and their dates of publication; statements of the designated or inferred types of these taxa and their provenances; and comments on the nomenclatural status of these names. Instances of the use of names or combinations subsequent to their original publication are, however, not listed. Of course, the choices of which taxa to recognize as valid and their proper arrangement reflect my own current views. This arrangement is outlined immediately hereafter to aid in finding taxa in this section. (Note that not all taxa in this summary list are necessarily valid; several are probable synonyms but have not been formally synonymized.) For a quick-reference summary of the names now in use for the Recent species of sirenians, see Appendix 5. – DPD Summary Classification and List of Taxa Recognized ORDER SIRENIA Illiger, 1811 Family Prorastomidae Cope, 1889 Pezosiren Domning, 2001 P. portelli Domning, 2001 Prorastomus Owen, 1855 P. sirenoides Owen, 1855 Family Protosirenidae Sickenberg, 1934 Ashokia Bajpai, Domning, Das, and Mishra, 2009 A. antiqua Bajpai, Domning, Das, and Mishra, 2009 Protosiren Abel, 1907 P. eothene Zalmout, Haq, and Gingerich, 2003 P. fraasi Abel, 1907 P. sattaensis Gingerich, Arif, Bhatti, Raza, and Raza, 1995 P. smithae Domning and Gingerich, 1994 ?P. minima (Desmarest, 1822) Hooijer, 1952 Family Trichechidae Gill, 1872 (1821) Subfamily Miosireninae Abel, 1919 Anomotherium Siegfried, 1965 1 Daryl P. -
