IUCN Red List version 2015.4: Table 7 Last Updated: 19 November 2015 Table 7: Species changing IUCN Red List Status (2014-2015) Published listings of a species' status may change for a variety of reasons (genuine improvement or deterioration in status; new information being available that was not known at the time of the previous assessment; taxonomic changes; corrections to mistakes made in previous assessments, etc. To help Red List users interpret the changes between the Red List updates, a summary of species that have changed category between 2014 (IUCN Red List version 2014.3) and 2015 (IUCN Red List version 2015-4) and the reasons for these changes is provided in the table below. IUCN Red List Categories: EX - Extinct, EW - Extinct in the Wild, CR - Critically Endangered, EN - Endangered, VU - Vulnerable, LR/cd - Lower Risk/conservation dependent, NT - Near Threatened (includes LR/nt - Lower Risk/near threatened), DD - Data Deficient, LC - Least Concern (includes LR/lc - Lower Risk, least concern). Reasons for change: G - Genuine status change (genuine improvement or deterioration in the species' status); N - Non-genuine status change (i.e., status changes due to new information, improved knowledge of the criteria, incorrect data used previously, taxonomic revision, etc.); E - Previous listing was an Error.

ABSTRACT Mountains offer replicated units with large biotic and abiotic gradients in a reduced spatial scale. This transforms them into well-suited scenarios to evaluate biogeographic theories. Mountain biogeography is a hot topic of research and many theories have been proposed to describe the changes in biodiversity with elevation. Geometric constraints, which predict the highest diversity to occur in mid-elevations, have been a focal part of this discussion. Despite this, there is no general theory to explain these patterns, probably because of the interaction among different predictors with the local effects of historical factors. We characterize the diversity of small non-volant mammals across the elevational gradient on Mount (Mt.) Kinabalu (4,095 m) and Mt. Tambuyukon (2,579 m), two neighboring mountains in Borneo, Malaysia. We documented a decrease in species richness with elevation which deviates from expectations of the geometric constraints and suggests that spatial Submitted 14 February 2018 Accepted 9 September 2019 factors (e.g., larger diversity in larger areas) are important. -

ABSTRACT. Information regarding trends in research on terrestrial species of the order Carnivora can provide an understanding of the degree of knowledge of the order, or lack thereof, as well as help identifying areas on which to focus future research efforts. With the aim of providing information on these trends, this work presents a review of the thematic focuses of studies addressing this order published over the past three de- cades. Relevant works published in 16 scientific journals were analyzed globally and by continent with respect of topics, species, and families. -
Ecology of Ringed Seals (Phoca Hispida) in Western Hudson Bay, Canada
Ecology of ringed seals (Phoca hispida) in western Hudson Bay, Canada by Magaly Vincent-Chambellant A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfilment of the requirements of the degree of DOCTOR OF PHILOSOPHY Department of Biological Sciences University of Manitoba Winnipeg Copyright © 2010 by Magaly Vincent-Chambellant Abstract Recently, Hudson Bay experienced unidirectional trends in temperature, sea-ice extent, time of break-up, and length of the open-water season. Predicted impacts on population dynamics of ice-associated species include habitat loss and shift in prey availability. The ringed seal (Phoca hispida) depends on a stable ice platform with sufficient snow depth and a productive open-water season for reproduction and survival. Evidence of ringed seal sensitivity to environmental variations has been reported, but mechanisms involved were poorly understood. In western Hudson Bay, density, life-history traits, and diet of ringed seals were monitored over two decades, providing an opportunity to understand the effects of climatic variations on the population dynamics of this long-lived carnivore. Ringed seal density was estimated through strip-transect analyses after aerial surveys were flown in western Hudson Bay in late spring during the annual moult in the 1990s and 2000s. During these periods, ringed seals were also sampled from Inuit subsistence fall harvests In Arviat, NU, and ages, reproductive status, percentage of pups in the harvest, body condition, and diet were assessed. Strong inter-annual variations in these parameters were observed, and a decadal cycle was suggested and related to variations in the sea-ice regime. -
The 2008 IUCN Red Listings of the World's Small Carnivores
The 2008 IUCN red listings of the world’s small carnivores Jan SCHIPPER¹*, Michael HOFFMANN¹, J. W. DUCKWORTH² and James CONROY³ Abstract The global conservation status of all the world’s mammals was assessed for the 2008 IUCN Red List. Of the 165 species of small carni- vores recognised during the process, two are Extinct (EX), one is Critically Endangered (CR), ten are Endangered (EN), 22 Vulnerable (VU), ten Near Threatened (NT), 15 Data Deficient (DD) and 105 Least Concern. Thus, 22% of the species for which a category was assigned other than DD were assessed as threatened (i.e. CR, EN or VU), as against 25% for mammals as a whole. Among otters, seven (58%) of the 12 species for which a category was assigned were identified as threatened. This reflects their attachment to rivers and other waterbodies, and heavy trade-driven hunting. The IUCN Red List species accounts are living documents to be updated annually, and further information to refine listings is welcome.

In particular, I would like to thank Dr. Aldo Rincon for his help in researching procyonids. I am so grateful to Dr. Anne-Claire Fabre; without her understanding of R and knowledge of 3D morphometrics this project would have been an immense struggle. I would also to thank Rachel Short for the late-night work sessions and discussions. I am extremely grateful to my advisor Dr. David Steadman for his comments, feedback, and guidance through my time here at the University of Florida. I also thank my committee, Dr. Bruce MacFadden, Dr. Jon Bloch, Dr. Elizabeth Screaton, for their feedback and encouragement.
