Abstract Primates are facing an impending extinction crisis. Here, we examine the set of conservation challenges faced by 100 primate species that inhabit Brazilian Amazon, largest remaining area primary tropical rainforest in world. The vast majority (86%) Brazil's Amazonian have declining populations. Primate population decline Amazonia has been driven principally deforestation related to production forest‐risk commodities including soy and cattle ranching, illegal logging setting fires, dam building, road rail construction, hunting, mining, confiscation conversion Indigenous Peoples' traditional lands. In a spatial analysis found 75% lands (IPLs) remained forested compared with 64% Conservation Units (CUs) 56% other (OLs). addition, richness was significantly higher on IPLs than CUs OLs. Thus, safeguarding land rights, systems knowledge, human rights is one most effective ways protect primates value ecosystems they inhabit. Intense public political pressure required global call‐to‐action needed encourage all countries, especially Brazil, as well citizens consumer nations, actively commit changing business usual, living more sustainably, doing can Amazon.

Massive actions have been and are being taken into protecting the world's primates from extinction, while study of properties genetic diversity, demographic history, ecological relationships will benefit understanding long-term survival a species. The Taihangshan macaque (Macaca mulatta tcheliensis), subspecies rhesus mulatta), is endemic to China currently restricted southern Mt. area. Herein, we evaluated population structure, history this using mitochondrial (Cytb high variable region I: HVR I) nuclear markers (microsatellite loci) 131 individuals collected 9 localities covering distribution range subspecies. Both phylogenetic analyses assignment revealed that wild populations macaques could be divided 2 major highly divergent clades, THS-east THS-west. Low diversity (π: 0.00266 ± 0.00016) but haplotype (Hd : 0.80352 0.015) were detected in macaques, particularly THS-east. Analyses suggested experienced first stable historical size Holocene early 19th century subtle decline then slight growth recent 200 years. We suggest bridging neighbor (i.e. setting corridors) would facilitate male-mediated gene flow subsequently increase populations.

Abstract South Africa’s extensive linear infrastructure network (which includes roads and power lines) is severely impacting the country’s historically recognised five primate species: greater or thick-tailed bushbaby ( Otolemur crassicaudatus ), southern lesser Galago moholi chacma baboon Papio ursinus vervet monkey Chlorocebus pygerythrus ) samango Cercopithecus albogularis ). We present African mortality data from two different types on a country wide scale, over long-term sampling period. Using road line electrocution acquired sources, we compare discuss collection methodologies, resulting quality identify current limitations in understanding direct impacts of which have important implications for conservation planning. Between 1996-2021 total 483 mortalities were recorded lines, majority former. Vervet monkeys most impacted by both whereas bushbabies experienced least number mortalities. Both sets showed numerous incidents where more than one individual was killed (roadkill: 4%, up to four incident; electrocutions: 13%, six incident). GPS coordinates available 61% roadkill records 65% records. Age sex carcasses not only 11% Although Africa leads continent regarding collection, there are still areas protocol that can be improved projects implementing mitigation measures (e.g. canopy bridges) reduce lacking. argue presented here should form basis future implementation recommend prominently as threat when developing national international Red Lists.

Infrastructures such as roads or railways fragment the forests, but they are also places of encounter between humans and wildlife. Some populations primates, especially macaques baboons, regularly seen on roadsides. As these primates involved in direct conflict with for access to space food, it is particular importance understand attitudes vehicle occupants towards primates. In this exploratory study, we interviewed 383 travelling an asphalt road crossing Kibale National Park, Uganda, assess how people perceive Olive baboons (Papio anubis) that present road, regulations aiming protect them (and other animal species). addition, daily monitored sides record leftovers anthropogenic food census vehicles passing by. Most respondents did not express any negative toward although visit fields gardens forage crops area. Few were concerned about ‘do litter’ regulation.

Abstract Primates are declining worldwide and rapid infrastructure expansion, particularly roads, threatens their habitat. New roads fragment habitats allowing anthropogenic activities to occur in once pristine ecosystems; this is impactful tropical areas with high endemic biodiversity, as occurring primates Colombia. However, temporal assessments of how impact local biodiversity rare. We conducted a comprehensive assessment the exposure Colombian from 1970 2015. Using spatially explicit species‐specific approach, we estimated critical road density patch size primate species can withstand before going locally extinct. Then, overlapping 15 (~40% present Colombia) ranges Colombia's networks over time, determined expansion scope within each habitat consequent fragmentation. Comparing size, degree time its vulnerability extinction. Our results show that between 2015, there were nearly 40 000 km 2 where at least one was risk extinction, due principally Andean Caribbean regions. these regions faced greatest impacts, an average 16% increase amount affected during period.

Published: June 16, 2022

Abstract Roads disrupt the canopy and can affect arboreal animals in different ways, such as reducing connectivity, generating habitat loss degradation, increasing direct mortality. Since mainly use for movement, mitigation measures these species usually focus on maintaining or restoring connectivity to guarantee safe crossings. Here we present a case study of Brazilian coastal road (ES-060) which described bridge multiple underpasses by three mammal compared data with roadkill records same vicinity crossing structures.

Movement dynamics of gibbons after the construction of canopy bridges over a park road

Folia Primatologica, Journal Year: 2022, Volume and Issue: 93(3-6), P. 347 - 359

Published: Sept. 20, 2022

Abstract Gibbons (Hylobatidae) are species highly adapted to tree-top living. Thus, their movement can be compromised due the negative impact roads have on canopy habitats. In this study, we built two single-rope artificial bridges and a ladder bridge at out of five locations where group white-handed gibbons ( Hylobates lar ) in Khao Yai National Park, Thailand were known cross main park road. We compared road crossing frequencies, home-range characteristics, other ad libitum observations during periods before after installation. After construction was complete, took 10 weeks use single rope navigate over During 442 follow observation hours 539 hours, 131 crosses observed. The adult female usually crossed first, showed clear preference for (92 crossings versus 5). approximately once day mostly both construction. There not significant changes rates from (crossing between tree branches ground) installation places installed using bridges). Nonetheless, with more being than ground installation, presumably safer. These findings suggest that will ground, risking predation, encountering people, or hit by vehicle, but provided safer option since no longer jumped across wide gaps constructed. Maintaining connectivity logically improves home range connectivity, potentially gene flow, safety dwellers. However, connecting areas which previously connected should considered carefully. new connection could disrupt dynamics, particularly defend territories, such as gibbons.
