African Penguin Colony
An Innovative and Inspiring Space for a Growing African Penguin Colony enguins are among the most iconic and beloved avian groups, and the PCincinnati Zoo & Botanical Garden is embarking on an opportunity to further their engagement in care and conservation of African Penguins. This species in particular is endangered in their native range and requires the collective focus of zoos, aquariums, and other conservation organizations to ensure its survival into the future. The Cincinnati Zoo is seeking to construct a new habitat space for African Penguins that will allow for our colony to grow from 11 birds to 30+, which will contribute immensely to ex-situ conservation efforts, not to mention inspiring our visitors to care more about the species’ plight. A brand new habitat offers the opportunity to dream and innovate and truly bring the best experience to its animal residents. The new African Penguin habitat at the Cincinnati Zoo will be three times larger than the current space and offer a variety of new habitat feature to maximize their welfare, including: a dynamic pool area to encourage natural swimming behavior and exercise, natural substrates to dig into and to promote improved foot health, outdoor heating and cooling so that penguins can stay outside longer in the year, and a dramatically larger indoor bedroom area with a pool and UV-transmitting skylights to ensure health and comfort during our Cincinnati winter. African Penguin reproduction will be a key goal of this new habitat, and the new habitat and bedroom area will offer the opportunity to expand our nesting sites and maximize successful rearing of chicks. -

[email protected] La hipótesis de Gaia propone que a partir de unas condiciones iniciales que hicieron posible el inicio de la vida en el planeta, fue la propia vida la que las modificó. Sin embargo, desde el inicio del Antropoceno la humanidad tiene un papel protagónico en dichas modificaciones, e.g. el aumento del CO2 en la atmósfera. Se estima que para fines de este siglo, se alcanzarían concentraciones de CO2 que el planeta no registró en los últimos 30 Ma. La información para comprender como funcionarían los sistemas terrestres con estos niveles de CO2 está contenida en los registros de períodos cálidos y en las grandes transiciones climáticas del pasado geológico. -
Skull Shape Analysis and Diet of South American Fossil Penguins (Sphenisciformes) Claudia Patricia Tambussi & Carolina Acosta Hospitaleche
Skull shape analysis and diet of South American fossil penguins (Sphenisciformes) Claudia Patricia Tambussi & Carolina Acosta Hospitaleche CONICET & Museo de La Plata, Paseo del Bosque s/n, 1900 La Plata, Argentina [email protected] [email protected] ABSTRACT – Form and function of the skull of Recent and fossil genera of available Spheniscidae are analysed in order to infer possible dietary behaviors for extinct penguins. Skull shapes were compared using the Resistant-Fit Theta-Rho- Analysis (RFTRA) Procrustean method. Due to the availability and quality of the material, this study was based on six living species belonging to five genera (Spheniscus, Eudyptula, Eudyptes, Pygoscelis, and Aptenodytes) and two Miocene species: Paraptenodytes antarticus (Moreno and Mercerat, 1891) and Madrynornis mirandus Acosta Hospitaleche, Tambussi, Donato & Cozzuol. Seventeen landmark from the skull were chosen, including homologous and geometrical points. Morphologi- cal similarities among RFTRA distances are depicted using the resulting dendrograms for UPGMA (unweighted pair-group method using arithmetic average) cluster analysis. This shape analysis allows the assessment of similarities and differences in the skulls and jaws of penguins within a more comprehensive ecomorphological and phylogenetic framework. Even though penguin diet is not well known, enough data supports the conclusion that Spheniscus + Eudyptes penguins specialize on fish and all other taxa are plankton-feeders or fish and crustacean-feeders. We compared representative species of both ecomor- phological groups with the available fossil material to evaluate their feeding strategies. Penguins are the most abundant birds, indeed the most abundant aquatic tetrapods, in Cenozoic marine sediments of South America. The results arising from this study will be of singular importance in the reconstruction of those marine ecosystems. -

Colour aberrations in African Penguins Spheniscus demersus. Marine Ornithology 46: 19–22. Colour aberrations among wild birds are of long-time interest because they are uncommon, particularly in seabirds, although recent publications have revealed varying forms of aberrations in cormorants and penguins. In African Penguins Spheniscus demersus, there have been previous sightings of abnormal plumages, particularly in Algoa Bay, South Africa. This paper reveals new cases of plumage aberrations in African Penguins: leucism, “brown,” and phaeomelanism, all within Algoa Bay. While all aberrations seemed of natural origin, one in the shape of a number eight may have resulted from human actions. Key words: African Penguin, abnormal plumages, Algoa Bay, leucism, phaeomelanism, “brown” INTRODUCTION but also an effort on the part of the scientific community to report these rare observations.

For the net diversification rate, d, we place a log-normal prior distribution with parameters1 M = −3:5 and S2 = 1:5. The 2.5% and 97.5% quantiles of this distribution are 1:6 · 10−3 and 0:57 implying that it well covers the interval (with the lowest 5% quantile of 0.02 and the largest 95% quantile of 0.15) estimated in [1] Figure 1. We place a Uniform(0,1) prior distribution for the turnover, ν, and Uniform(0,1) prior distri- bution for the fossil sampling proportion, s.

Abstract: Emerging viral diseases have become a significant concern due to their potential con- sequences for animal and environmental health. Over the past few decades, it has become clear that viruses emerging in wildlife may pose a major threat to vulnerable or endangered species. Diphtheritic stomatitis, likely to be caused by an avipoxvirus, has been recognised as a signifi- cant cause of mortality for the endangered yellow-eyed penguin (Megadyptes antipodes) in New Zealand. However, the avipoxvirus that infects yellow-eyed penguins has remained uncharacterised. Here, we report the complete genome of a novel avipoxvirus, penguinpox virus 2 (PEPV2), which was derived from a virus isolate obtained from a skin lesion of a yellow-eyed penguin. The PEPV2 genome is 349.8 kbp in length and contains 327 predicted genes; five of these genes were found to be unique, while a further two genes were absent compared to shearwaterpox virus 2 (SWPV2). -
