Morphometry and allometry of the postnatal marsupial lung development: an ultrastructural study

An utrastructural morphometric study of the postnatally remodelling lungs of the quokka wallaby (Setonix brachyurus) was undertaken. Allometric scaling of the volumes of the parenchymal components against body mass was performed. Most parameters showed a positive correlation with body mass in all the developmental stages, except the volume of type II pneumocytes during the alveolar stage. The interstitial tissue and type II cell volumes increased slightly faster than body mass in the saccular stage, their growth rates declining in the alveolar stage. Conversely, type I pneumocyte volumes increased markedly in both the saccular and alveolar stages. Both capillary and endothelial volumes as well as the capillary and airspace surface areas showed highest rates of increase during the alveolar stage, at which time the rate was notably higher than that of the body mass. The pulmonary diffusion capacity increased gradually, the rate being highest in the alveolar stage and the adult values attained were comparable to those of eutherians.

Tibial Plateau angles with and without cranial cruciate ligament rupture: comparison between different dog populations and a wolf population.

The tibial plateau angles (TPA) of dogs with and without cranial cruciate ligament (CrCL) injuries were evaluated and further compared to the TPAs of dogs from a previous population and of wolves. Similar TPA measurements were found in all groups, suggesting that any possible changes in breeding practises, breed preferences, nutrition or other factors have not significantly influenced the TPA over time. Moreover, a difference was not found in the TPA between any group and the group affected with CrCL injury, suggesting that the TPA is not a clinically relevant predisposing factor in the development of canine CrCL rupture.

Recovery of large carnivores in Europe's modern human-dominated landscapes.

The conservation of large carnivores is a formidable challenge for biodiversity conservation. Using a data set on the past and current status of brown bears (Ursus arctos), Eurasian lynx (Lynx lynx), gray wolves (Canis lupus), and wolverines (Gulo gulo) in European countries, we show that roughly one-third of mainland Europe hosts at least one large carnivore species, with stable or increasing abundance in most cases in 21st-century records. The reasons for this overall conservation success include protective legislation, supportive public opinion, and a variety of practices making coexistence between large carnivores and people possible. The European situation reveals that large carnivores and people can share the same landscape.

The Timber Wolf Preservation Society: Developing a Management Plan for Long Term Sustainability & Prosperity

The timber wolf has been eradicated from most of its North American range, but in recent decades has been recovering. The Timber Wolf Preservation Society (TWPS) was founded to assist in the reestablishment of wolf populations in Wisconsin. The public education mission of the TWPS is a key element in increasing human tolerance of wolves. This capstone summarizes principles of wolf ecology and the care of captive mammals. Challenges faced by the TWPS, including more effective board management practices and the need for a strategic plan, are also identified. Suggestions and recommendations for improving the TWPS administration, board governance and organizational growth are presented to allow the TWPS to become sustainable and continue to contribute to wolf recovery efforts in Wisconsin.

Leishmaniose em Lobo Ibérico

Quando falamos de vida selvagem em Portugal, pensamos logo no Lobo Ibérico (Canis lupus signatus), que ao longo das últimas décadas tem vindo a sofrer um notório declínio populacional, apenas contrariado pelas medidas protecionistas entretanto implementadas. A diminuição do número de lobos em Portugal resulta principalmente da perseguição direta a que foram sujeitos e da destruição do seu habitat natural. Outra causa de redução/extinção de pequenas populações locais e fragmentadas de grandes carnívoros em outras partes no mundo tem sido as doenças infeciosas. Sendo monitorização da presença de patologias em animais silvestres fundamental no controle das zoonoses emergentes e na conservação das espécies. Neste contexto pretendeu-se elaborar um estudo de determinação da ocorrência de Leishmaniose, no Lobo Ibérico. Assim, recolheram-se aleatoriamente 42 amostras de sangue a lobos residentes no Parque Nacional Peneda-Gerês que, posteriormente foram testadas recorrendo-se ao método de ELISA. Através desta técnica, detetou-se que das 42 amostras testadas apenas uma amostra (2,4%) possuía anticorpos anti-leishmania. Um dos motivos para a obtenção de resultados pouco significativos poderá dever-se ao reduzido leque amostral. Concluímos, então, que são necessários estudos adicionais para avaliar a importância do Lobo Ibérico na transmissão e propagação da Leishmaniose.

Imperfect Creatures : Vermin, Literature, and the Sciences of Life, 1550-1750 /

Plagues of pests have always been a part of recorded history, but they hold special significance in the early modern period. 'Imperfect Creatures' is the first full-length study to investigate the shifting, unstable, but foundational status of “vermin” as creatures and category in the early modern literary and scientific imagination.
