“…The images are produced with the radiative transfer code skirt [66]. This code generates images of the galaxy in the u, g, and r SDSS filters within a 30 kpc aperture of the galaxy centre; the dust distribution is inferred from the gas metal distribution in the interstellar medium [67,68]. From those images one can see that the majority of the selected objects shows clearly a disc component.…”

“…The so-called "Power radius" is R P03 = Figure 4. Pairs of mock three-colour composite grid observations for the 10 simulated galaxies in the EAGLE IR run with edge-on (left) and face-on (right) projections, within a 30 kpc aperture of the galaxy centre obtained using the skirt [66] radiative transfer code as described by [67,68] 3.6 kpc, 1.8 kpc and 1.8 kpc 4 for the EAGLE IR, EAGLE HR and APOSTLE IR runs. The very concept of convergence -that ever increasing resolution will cause the measured quantity to asymptotically tend towards some finite value -is much less clear in simulations that feature baryon physics, and so the innermost radius at which the profiles may be considered converged is ill-defined.…”

Abstract. We study high-resolution hydrodynamic simulations of Milky Way type galaxies obtained within the "Evolution and Assembly of GaLaxies and their Environments" (EA-GLE) project, and identify those that best satisfy observational constraints on the Milky Way total stellar mass, rotation curve, and galaxy shape. Contrary to mock galaxies selected on the basis of their total virial mass, the Milky Way analogues so identified consistently exhibit very similar dark matter profiles inside the solar circle, therefore enabling more accurate predictions for indirect dark matter searches. We find in particular that high resolution simulated haloes satisfying observational constraints exhibit, within the inner few kiloparsecs, dark matter profiles shallower than those required to explain the so-called Fermi GeV excess via dark matter annihilation.

“…The few primate‐focused studies in which GPS collars have been deployed thus far have largely presented various kinds of data on collar performance (e.g., Markham & Altmann, ; Pebsworth, Morgon, & Huffman, ; Sprague, Kahaya, & Hargihara, ). Although documenting GPS‐collar performance is important at this relatively early stage to test their value in primate‐typical habitats, improve the effectiveness of collars, and determine the best type of collar for a given study, we concur with many that it is also important to discuss the extent to which the process of GPS‐collar placement affects the animals themselves, with the goal of minimizing negative effects on individuals in the future (Ancrenaz, Setchell, & Curtis, ; Brett, Turner, Jolly, & Cauble, ; Honess & MacDonald ; Jolly, Phillips‐Conroy, & Müller, ; Juarez, Rotundo, Berg, & Fernández‐Duque, ; Jung & O'Donovan, ; Jung, Thompson, Hickey, & Titman, ; Trayford & Farmer, ). However, data are rarely presented on the collaring procedure itself or on the health, survival, or reproduction of collared individuals (Fehlmann et al, ; Markham & Altmann, ; Markham et al, ; Pebsworth et al, ; Pyritz, Kappeler, & Fichtel, ; Ren, Li, Long, Grüter, & Wei, ; Sprague et al, ).…”

As the value of Global Positioning System (GPS) technology in addressing primatological questions becomes more obvious, more studies will include capturing and collaring primates, with concomitant increased risk of adverse consequences to primate subjects. Here we detail our experiences in capturing, immobilizing, and placing GPS collars on six olive baboons (Papio anubis) in four groups and 12 vervet monkeys (Chlorocebus pygerythrus) in five groups in Kenya. We captured baboons with cage traps and vervets with box traps, immobilized them, and attached GPS collars that were to be worn for 1 year. Adverse consequences from the trapping effort included incidental death of two nonsubjects (an adult female and her dependent infant), temporary rectal prolapse in one baboon, superficial wounds on the crown of the head in two vervets, and failure to recapture/remove collars from two baboons and two vervets. Obvious negative effects from wearing collars were limited to abrasions around the neck of one vervet. A possible, and if so, serious, adverse effect was greater mortality for collared adult female vervets compared with known uncollared adult female vervets, largely due to leopard (Panthera pardus) predation.Collared animals could be more vulnerable to predation because trapping favors bolder individuals, who may also be more vulnerable to predation, or because collars could slow them down or make them more noticeable to predators. Along with recommendations made by others, we suggest that future studies diversify trapping bait to minimize the risk of rectal prolapse, avoid capturing the first individuals to enter traps, test the movement speeds of collared versus noncollared animals, include a release system on the collars to avoid retrapping failure, and publish both positive and negative effects of capturing, immobilizing, and collaring.

“…Animals currently housed in rescue centres around the world, many of which are globally threatened, could, potentially, offer the last chance to save species through captive breeding and translocation (Trayford & Farmer 2012). We now discuss alternatives to the question raised earlier: What is the most viable option regarding compassionate conservation (Bekoff 2013a) for animals that cannot be released?…”

With the number of threatened species in rescue centres rising, scientific reports on the functioning and success of such centres is essential. Compassionate conservation tries to bridge the gap between animal welfare advocates and conservation biologists, recognising the benefits of preserving a species and its individuals. A case in point is that of Indonesia's threatened slow lorises Nycticebus spp., where illegal trade is decimating wild populations of these primates. We present 4 yr of data from Ciapus Primate Centre in Indonesia, which received 180 slow lorises between 2008 and 2011. We show that > 85% of these primates were unsuitable for reintroduction; 23 slow lorises that were deemed suitable for reintroduction were released to the wild between 2010 and 2013 and were followed with radio tracking. Eleven of them died (on average 76 d post-release), 1 was recaptured (148 d post-release), 6 are no longer being monitored (after, on average, 263 d post-release) and their status is unknown, and 5 are still being monitored (average 226 d post-release, as of December 2013). The challenges posed by work with slow lorises in the Ciapus Primate Centre over these 4 yr, with release success highly variable, show that even with concerted effort, rescue centres need to consider alternative options. We review such options, considering the pros and cons of euthanasia, life in captivity and reintroduction to the wild. We conclude that in today's global conservation crisis, it can only be beneficial to combine the expertise of animal welfare practitioners and conservation biologists.
