“…We found no differences between the right and left kidneys for all biometric parameters, which is similar to previous studies in S. apella 29,30 and Macaca mulatta, 7 but contrasts with studies in other species. For instance, studies in the platyrrhine primates A. azarae infulatus 8 and in C. jacchus 25 reported that the left kidney had a greater height and length than the right kidney.…”

“…The ultrasound appearance of the kidneys in both species was similar to that described previously in other Platyrrhines, including A. fusca , 28 S. apella , 29,30 A. azarae infulatus 10 and S. collinsi , 26 in which both kidneys had an elliptical shape, echogenicity and homogeneous cortical echotexture with preserved corticomedullary differentiation. One study in C. jacchus , reported a poor corticomedullary distinction in the kidneys, 25 which could have been due to the small size of these primates.…”

“…Previous studies have characterized kidney size in different age classes in NHP such as Callithrix jacchus , 25 A. azarae infulatus , 8 Saimiri collinsi , 26 and Macaca fascicularis 27 . Although a few studies have described the renal ultrasonography in Alouatta fusca , 28 and S. apella , 29,30 these studies were limited to adults. The goal of this study was to evaluate the kidney by ultrasound in infant, juvenile, and adults A. caraya and S. apella to (1) describe age‐related changes in renal ultrasonographic appearance, (2) establish the renal biometric parameters per age group, (3) compare species differences in renal volume and kidney growth, and (4) to test potential correlations between renal volume and age, renal function tests (urea and creatinine) and RBC.…”

Background Comparative studies of kidney morphophysiology in nonhuman primates can help us investigate interspecies differences in growth and aging patterns. Methods We tested the effect of age and sex in renal morphophysiology in 21 Alouatta caraya and 21 Sapajus apella (age range = 0.5–26 years) by ultrasound, red blood cell (RBC) count, and kidney function tests. Results A. caraya had greater growth rate and absolute renal volume than S. apella, but the latter showed a greater relative renal volume and RBC count. There was a negative relationship between RBC and age, a positive relationship between creatinine and body mass, and an apparent negative relationship between creatinine and age only in S. apella. Conclusions Our results indicate that A. caraya has a faster aging mechanism than S. apella, and the higher relative kidney volume in S. apella is suggestive of high metabolic demands in this species.

Predictors of animal sponsorship to support zoo‐based conservation activities

Public donations are an important form of fundraising for zoos and are used to support conservation activities. Understanding what influences zoo animal sponsorship by the public is crucial if zoos are to optimize strategies for increasing income from sponsors. Using sponsorship data obtained from seven diverse zoos within the UK, we used a phylogenetically informed approach to investigate predictors of the number of sponsors a species receives. We found no support for an effect of body mass, conservation status, solitary versus group housing, phylogenetic distance from humans, daily activity patterns, or the diet of the species on the number of sponsors a species attracts. However, we found strong phylogenetic signal, suggesting that particular groups of animals attract disproportionate sponsorship attention (but the specific species within these groups is of limited importance). Moreover, we found support for species with common names that are found toward the start of the alphabet having more sponsors. This is likely driven by the common practice of listing species that can be sponsored in alphabetical order when presenting them to potential sponsors (with people being more likely to choose species near the start of a list). Interestingly, the lack of effect of body mass, phylogenetic distance, and conservation status contrast with previous work on non‐zoo conservation preferences, suggesting possible differences between motivations of zoo and non‐zoo conservation donors, or between animal sponsorship and other forms of conservation involvement. We suggest two strategies for maximizing sponsorship for zoo animals. If zoos manage sponsorship income as a collective pool then allowing sponsorship of a range of species within particularly well‐sponsored animal groups should improve uptake. Alternatively, if zoos allocate sponsorship income to the specific species sponsored, then funding may be effectively diverted to priority species simply by altering the order of lists of animals which can be sponsored.

Renal evaluation with B‐mode and Doppler ultrasound in captive tufted capuchins (Sapajus apella)

Abstract: Both kidneys showed similar morphometric parameters by B-mode ultrasound, whereas RI by spectral Doppler decreased progressively from renal artery to interlobar and arcuate arteries.
