Abstract
Primates are extracted from the wild for the pet trade across the world. In Madagascar, lemurs are kept as illegal pets and an understanding of lemur pet ownership at the national level is lacking. In 2013 and 2016, we undertook a national survey in 11 of Madagascar's 22 administrative regions (n = 28 towns) with 1,709 households. To our knowledge, this is the first national survey of the household ownership of pet primates in a country where they are endemic. In the 1.5 years prior to being surveyed, 8% ± 4% (towns as replicates) of respondents had seen a captive lemur while a further 0.7% ± 0.5% of respondents had owned one personally. We estimate that 33,428 ± 24,846 lemurs were kept in Malagasy households in the six months prior to our survey efforts, with 18,462 ± 12,963 of these pet lemurs estimated in urban household alone. Rates of lemur ownership did not differ by province but increased with the human population of a town and with the popularity of the town on Flickr (a proxy indicator for tourism). We found that the visibility of pet lemur ownership did not differ across the country, but it did increase with the size of the town and popularity with tourists. Areas with visible pet lemurs were not always the areas with the highest rates of pet lemur ownership, highlighting that many pet lemurs are hidden from the general public. Our study highlights the need for conservation programs to consider both the proportion of inhabitants that own pet lemurs and the total number of lemurs that are potentially being kept as pets in those towns. We close by noting that for some species, even just a small amount of localized live extraction for pet ownership could be enough to cause localized population extinctions over time. Moreover, an urgent response is needed to combat a recent and alarming rise in illegal exploitation of biodiversity across Madagascar.

Abstract
Primates are kept as pets for various reasons including as indicators of wealth. Ownership of primates can also be influenced by religion. In Madagascar, thousands of lemurs are kept as pets, but the roles of wealth and religion in the ownership of captive lemurs have not been explored. We use quantitative and qualitative data to examine these aspects of ownership. Quantitative data were collected (July to August 2016) in households (n = 596) of 12 urban and rural towns in Madagascar using semi-structured interviews. International standards for research ethics were followed. Research was approved by an ethics oversight committee. We also opportunistically visited 13 religious facilities. Qualitative data were used to frame the context of the quantitative data. We found that pet lemur owners do not speak about their lemurs as a symbol of wealth, but non-owners associate pet lemurs with wealth. Therefore, status/wealth may be a motivating factor in the ownership of pet lemurs. We also found evidence that Catholic entities in Madagascar sometimes take in captive lemurs when the owner can no longer care for the animal (being viewed as animal-friendly institutions). However, we did not find evidence of religion (institutional or traditional) influencing the ownership of pet lemurs.

Abstract
Lemurs are the most threatened group of mammals on earth. Lemur catta (ring-tailed lemur) represents one of the most iconic lemur species and faces numerous anthropogenic threats in the wild. In this study, we present population estimates from 32 sites across the range of L. catta, collected from primary and secondary data sources, to assess the number of ring-tailed lemurs left in the wild. We estimate that there are approximately 2,220 individual L. catta remaining in the 32 sites considered. We note local extinctions of populations of L. catta in at least 12 of the 32 sites examined, and that significantly more extinctions occurred in areas without some form of protection. This decrease in extant populations could represent a decrease of more than 95% of all ring-tailed lemurs in Madagascar since the year 2000. While these results should be considered preliminary, we stress the rapid decline of the species and note that habitat loss, bushmeat hunting and the illegal pet trade are driving populations to local extinction. Based on the data presented here, urgent and immediate funding and conservation action are crucial to ensure the viability of the remaining wild populations of ring-tailed lemurs.

Abstract
PURPOSE To characterize expression of the transcriptional activator, Pax-2, in the mouse lower genitourinary tract. MATERIALS AND METHODS Expression of Pax-2 was studied by Northern analysis, ribonuclease protection and immunohistochemistry. RESULTS Immunostaining revealed localized expression in the epithelium of the ductus deferens and epididymis at all time points from birth to adulthood. Expression in these structures in adult mice was confirmed by Northern analysis and ribonuclease protection assays. CONCLUSION Pax-2 is a transcriptional regulator expressed in the epithelium of the ductus deferens and epididymis and may be a regulator of epithelial genes involved in sperm maturation and support.

Abstract
1. Captopril (100 mg/kg, orally) decreased blood pressure in spontaneously hypertensive (SH) rats. 2. Bilateral adrenalectomy either before or after captopril administration did not alter the antihypertensive effect of captopril. 3. Bilateral nephrectomy reversed the established antihypertensive effect of captopril and prevented any change in blood pressure to a subsequent dose of captopril. 4. It is concluded that kidneys but not adrenal glands are essential to the antihypertensive actions of captopril in SH rats.
