  • Cladocera: Anomopoda: Daphniidae) from the Lower Cretaceous of Australia
    Palaeontologia Electronica palaeo-electronica.org Ephippia belonging to Ceriodaphnia Dana, 1853 (Cladocera: Anomopoda: Daphniidae) from the Lower Cretaceous of Australia Thomas A. Hegna and Alexey A. Kotov ABSTRACT The first fossil ephippia (cladoceran exuvia containing resting eggs) belonging to the extant genus Ceriodaphnia (Anomopoda: Daphniidae) are reported from the Lower Cretaceous (Aptian) freshwater Koonwarra Fossil Bed (Strzelecki Group), South Gippsland, Victoria, Australia. They represent only the second record of (pre-Quater- nary) fossil cladoceran ephippia from Australia (Ceriodaphnia and Simocephalus, both being from Koonwarra). The occurrence of both of these genera is roughly coincident with the first occurrence of these genera elsewhere (i.e., Mongolia). This suggests that the early radiation of daphniid anomopods predates the breakup of Pangaea. In addi- tion, some putative cladoceran body fossils from the same locality are reviewed; though they are consistent with the size and shape of cladocerans, they possess no cladoceran-specific synapomorphies. They are thus regarded as indeterminate diplostracans. Thomas A. Hegna. Department of Geology, Western Illinois University, Macomb, IL 61455, USA. ta- [email protected] Alexey A. Kotov. A.N.

    The Arctic in 2045: A Long Term Vision Okalik Eegeesiak | Wilton Park, London, UK| February 17, 2016 An Inuit Vision of the Arctic in 2045 (check against delivery) Ullukkut, Good afternoon. My name is Okalik Eegeesiak. First, thank you to the organizers for the invitation to speak at this conference at such a beautiful and inspiring venue and to the participants who share the value of the Arctic and its peoples. A thirty year vision for the Arctic is important. Inuit believe in a vision for the Arctic – our vision looks back and forward – guided by our past to inform our future. I hope my thoughts will add to the discussion. I will share with you about what Inuit are doing to secure our vision and how we can work together for our shared vision of the Arctic. Inuit have occupied the circumpolar Arctic for millennia – carving a resilient and pragmatic culture from the land and sea – we have lived through famines, the little ice age, Vikings, whalers, missionaries, residential schools, successive governments and we intend to thrive with climate change. A documentary was recently released in Canada that told of the accounts of two Inuit families and an single man from Labrador, Canada now called Nunatsiavut – these Inuit were brought to Europe in the 1880’s and displayed in “zoo’s”. Their remains are still in storage in museums in France and Germany and their predecessors are now working to repatriate them. I share these struggles and trauma to illustrate that we have come a long way… and I am with a solid foundation of our history.

This provides an opportunity to revisit the issue of First Nations’ standard of living and quality of life. Some First Nations made rapid progress from 2001 to 2016, as measured by the CWB. Others lost ground, in some cases substantial ground. This report will examine both groups in a search for factors associated with First Nations’ progress and regress. The good news for First Nations reserve communities is that their average CWB increased steadily over the 35 years from 1981 to 2016. Less good is the news that the gap between First Nations and other Canadian communities, after seeming to narrow a little in the 1990s, widened again and was almost as great in 2016 (19.1 points) as it was in 1981 (19.5 points). CWB scores are used in this paper to construct a new variable called Community Well-Being Change, 2001–2016, abbreviated as CWB-C.

  • Arctic Council: Navigating Global Change
    At a glance February 2015 Arctic Council: navigating global change Climate change and globalisation have increased the focus on the Arctic region and thus on the Arctic Council (AC) as a circumpolar player. Ahead of the ministerial meeting in April 2015 – where the AC will decide on the EU's bid for observer status – preparations for the US to take over the rotating chairmanship for 2015-17 are rekindling debate on the AC's future priorities and role. Informal forum for Arctic cooperation The inter-governmental Arctic Council (AC) was founded in 1996 by the five Arctic coastal states, Canada, Denmark (including Greenland and the Faroe Islands), Norway, Russia, and the United States, plus Finland, Iceland and Sweden, as a 'high level forum' to promote sustainable development and environmental protection. Since then, the AC has continued to develop its organisational structures, for example by making the temporary secretariat in Tromsø, Norway, permanent in 2013. However, the AC lacks legal personality and formally speaking is not an international organisation. Its decisions and standards are consensual and non-binding, and it does not impose policies or payments on its member states. On the basis of this soft legal status, the AC has established itself as a key forum for Arctic scientific and policy cooperation. Between the biennial AC Ministerial Meetings, the eight member states are represented by appointed national Senior Arctic Officials (SAOs), who meet at least twice a year. The current membership would only change if Greenland were to gain full independence, causing Denmark to lose its status as an Arctic state.

Because of successful survival and an expanding distribution range, the addition of Cercopagis to the Baltic fauna is considered to be permanent. What has previously been cited as Cercopagis pengoi encompasses the morphology of several other species, subspecies and forms. Either a number of morphologically similar species is present, or there is a number of spurious species in Cercopagis. The last hypothesis is favoured. The spatial distribution pattern of Cercopagis, as well as that of total zooplankton, was correlated with depth. Deep (>100 m) and shallow (<10 m) stations had significantly lower abundance than stations of intermediate depth (<100 m). An overview of the distribution of C. pengoi group in fresh and brackish waters suggests a high tolerance to environmental factors, but with differences among taxa.

Breve definición del grupo y principales caracteres diagnósticos El orden Ctenopoda es un pequeño grupo de crustáceos branquiópodos con más de 50 especies a nivel mundial presentes especialmente en aguas continentales, excepto dos géneros (Penilia Dana, 1852 y Pseudopenilia Sergeeva, 2004) que habitan en aguas marinas. Se caracterizan por su pequeño tamaño, por una tagmosis poco aparente, diferenciando una región cefálica y una región postcefálica (ésta recu- bierta por un caparazón bivalvo), por sus toracópodos (o apéndices torácicos) homónomos (o sea, sin una diferenciación marcada entre ellos), y por no presentar efipio para proteger los huevos gametogenéticos (al contrario que los Anomopoda; véase Sala et al., 2015). Al igual que los Anomopoda, los primeros restos fósiles inequívocos de Ctenopoda pertenecen al Mesozoico (Kotov & Korovchinsky, 2006). 1.1. Morfología En general, el cuerpo de los Ctenopoda es corto, con una forma más o menos elipsoidal o ovalada, y comprimido lateralmente. La cabeza suele ser grande, no está recubierta por un escudo o yelmo cefálico (en contraposición con los Anomopoda), y concede protección a los órganos internos, principalmente el ojo compuesto, el ojo naupliar (no presente en todas las especies), y parte del sistema nervioso.
