“…Continued support for participatory and jurisdictional REDD+ programs also appears effective though this approach requires realistic expectations among local communities regarding benefits and participation, secured land tenor, and a mix of intervention strategies including incentives, disincentives, and introduction of alternative livelihoods (e.g., Davis and Goldman 2017; Simonet et al, 2019; Dupuits & Cronkleton 2020). Agroforestry research related to night monkey species is limited, though a study in the northern Andes suggests that coffee plantations can benefit night monkeys while also providing farmers with income (Guzmán et al, 2016). We have previously documented that the black-headed night monkey is quite common in secondary forest and that they make use of orchards (Helenbrook et al, 2020).…”

Deforestation rates in the Brazilian Amazon have been steadily increasing in recent years. Due to recent government policy, the projected growth of agriculture and expansion of the cattle industry is expected to further strain biodiversity across the region, with many wideranging primate species within these areas facing declines as a result. In this study, we examined 15 the anthropogenic impact on the widely distributed black-headed night monkey, Aotus nigriceps, which is listed as least concern but whose distribution and population status has yet to be assessed. In this study, we 1) modeled species distribution in A. nigriceps; 2) estimated impact of habitat loss and degradation on population trends; and 3) highlight landscape-based conservation actions which maximize potential for their long-term sustainability in the region. We found the 20 black-headed night monkey to be restricted by biotic and environmental factors such as higher elevation, low temperature range, low isothermality and high forest cover. Over the last two decades, over 132,908 km 2 of tree cover (18.3 %) within their documented range has been lost.We found only 40.4 % of their range contained suitable habitat, a loss of 17.1 % from their estimated distribution in 2000, and just over 22.3 % of suitable habitat was in protected areas. 25Projected deforestation rates across present-day modeled distribution of A. nigriceps equates to an additional loss of 37,295 km 2 of habitat over the next decade. This study demonstrates how this species of least concern actually has a far smaller distribution and is likely more at risk than previously described. The future impact of continued expansion of mono-cultured crops, cattle ranching, and wildfires is still unknown. However, expanded use of participatory and 30 jurisdictional REDD+, sustainable agroforestry in buffer zones, secured land tenor for indigenous communities, maintenance of wildlife corridors, and the expansion and strengthening of protected areas can help ensure viability and reduce risk of widespread loss for this and other species throughout the Amazon Basin.

“…The fi nal map, along with criteria maps, demonstrates this region has a potential to increase matrix permeability due to proximity between signifi cant remnants and protected areas. Such an endeavor would be possible by implementing one or more green corridors (Hamad;Kolo;Balzter, 2018) or ecological stepping stones (for example, using backyard agroforestry) (Cambui et al, 2017), which would provide structural connectivity (Metzger, 2006;Guzmán et al, 2016) for remnants, with future expectations of functional connection (Hernández et al, 2015).…”

The preservation in situ, through the establishment of legally protected areas, is one the approaches to mitigate environmental impact and protect biodiversity in the long term. The Piedade municipality shows a favorable set of conditions for consolidating protected areas (i.e. relatively low urbanization rates, the presence of forest remnants, and portions of relevant conservation units). In this context, the present study proposed the definition of priority areas for protection using Multicriteria Evaluation (MCE). The specific objectives were to identify the criteria and weights that are important for defining protected areas and to evaluate which method of MCE, whether the Weighted Linear Combination (WLC) or the Ordered Weighted Averaging (OWA) would be more appropriate. Using the Participatory Technique (PT), we defined criteria and weights. WLC and OWA made possible the identification of areas likely to become protected, but the first method produced more general and less flexible solutions. On the other hand, OWA provided a greater number of possible answers to the question of interest. Thus, showing the low-risk level, the OWA map was considered most suitable for the study proposal.

“…That the owl monkey populations in their native habitat of South American countries such as Colombia and Peru are being depleted due to malarial drug testing (Anon, 1973;Herrera et al, 2002), international trade (Svensson et al, 2016) as well as Amazonian deforestation leading to habitat loss (Brumback, 2001;Shanee et al, 2013;Guzman et al, 2016) is a cause of concern to many primatologists and environmental scientists. Conservation status of Aotus differs according to species/subspecies and countries.…”

Since 2002, our research muse has been owl monkey (Aotus), a native to Neo-tropical region. Due to their evolutionary choice of nocturnal life, owl monkeys do possess many secrets which diurnal living species like humans still cannot fathom. As of now, nothing is known about the circadian variation of melatonin in owl monkeys. Simply stated, two established facts are, (1) melatonin promotes sleep in diurnal primates including humans. (2) Melatonin levels in the cerebrospinal fluid, serum and plasma of diurnal primates like rhesus monkey, chacma baboon, common marmoset and humans peak during night hours. If this is so, how owl monkeys maintain their night alertness and daytime sleep routine and what role melatonin plays in the circadian zeitgebers of owl monkeys still remains a puzzle to be solved.
