The non-invasive collection of biological samples has proven useful to study a diverse array of research topics worldwide. Here, we present a systematic bibliographical synthesis exploring how the non-invasive collection of genetic samples has been used to study avian populations in the Neotropics. We searched international online databases for scientific publications, spanning from 2007 to 2017, to describe the trends and identify the sample types used, species studied, and research questions addressed. The analysis of 21 articles showed that shed feathers were most frequently used (66.7% of articles), followed by carcasses (14.2%), eggs (9.5%), and non-invasively obtained blood (4.8%); one study used both feces and shed feathers. Most studies addressed population genetic issues (38.1%), followed by species identification (28.6%), phylogenetic questions (14.3%), molecular sexing (9.5%), and parentage analyses (9.5%). Brazil produced almost half (47.6%) of the publications retrieved. Despite an increasing interest in using non-invasive sampling to study Neotropical avifauna, its application is still largely concentrated in the most developed countries in this region and to explore a limited number of questions. A more regular use of non-invasive sampling would help advance the knowledge of ecological, behavioral, genetic, and evolutionary aspects of Neotropical birds. Investigating the extent of human–wildlife conflict, such as impact of road-kills, illegal traffic, and collision with aerial infrastructure or unmanned vehicles, is an underexplored avenue of research in which this method could be of much help. Non-invasive genetic sampling can help tackle conservation problems and pave the way to scientifically informed conservation policies in this avian biodiversity hotspot.

“…DNA extraction was performed with a DNeasy Blood & Tissue extraction kit (Qiagen); in particular, the feathers were processed using the method used by Morales-Contreras et al (2016). To reduce the probability of obtaining pseudogenes (Pereira & Baker, 2004a), three mitochondrial regions larger than 1000 bp were amplified using the polymerase chain reaction (PCR) of Cytochrome Oxidase I (COI), NADH subunit 2 (ND2), and Cytochrome b (Cyt b) and the noncoding nuclear gene MUSK (muscle skeletal receptor tyrosine kinase).…”

Genetic diversity in Mexican wild populations of the Great Curassow (Crax rubra)

The Great Curassow (Crax rubra) is a Neotropical bird with a wide distribution; it is classified under different threat categories and is listed as a vulnerable species by the IUCN. The Official Mexican Standard, the NOM-059-SEMARNAT-2010, indicates that the Great Curassow is a threatened species, and the subspecies Crax rubra griscomi, which is restricted to the island of Cozumel, is classified as critically endangered. Habitat loss and fragmentation, hunting, overexploitation, and illegal trade are among the main factors that have placed the bird at an endangered status. The objective of the present study was to determine the genetic structure and variation of the species within the Mexican populations of Crax rubra by using three mitochondrial markers, and one nuclear marker (COI, ND2, Cyt b, and MUSK). We used 47 samples obtained by noninvasive collection (feathers) including the two different color phases of the female plumage: dark brown and barred (rare in Mexico). Gene flow between the remaining populations is recent and extensive, even between the continental and the island population (C. r. griscomi). The results indicate that the subspecies C. r. rubra and C. r. griscomi do not present a marked genetic differentiation because the second exhibits an exclusive haplotype and a shared haplotype. With this study, we provide the first genetic-geographic approximation of the curassow in Mexico, where a gradual geographic differentiation is observed between the western and eastern populations of the Isthmus of Tehuantepec, and we provide a baseline for future studies. Finally, the information obtained indicates that important genetic diversity persists in the Mexican populations of the Great Curassow and that sufficient conservation within the ecosystems of these subspecies can be obtained by protecting them from overexploitation and by conserving and restoring their habitat.

“…Camera traps can be used to obtain information on population abundance, behaviour, habitat occupancy, and population structure (Silveira et al 2003;Claridge et al 2010). Non-invasive genetic monitoring, including the use of faecal samples, can provide information on population abundance, population structure, sex, diet, habitat occupancy, and population genetic diversity (Piggott et al 2006a;Lachish et al 2011;Tende et al 2014;Moßbrucker et al 2015;Morales-Contreras et al 2016;Camp et al 2020;Bannister et al 2020).…”

Thirty-nine endangered brush-tailed rock-wallabies (Petrogale penicillata) were reintroduced to Grampians National Park, western Victoria, between 2008 and 2012. Subsequent high mortality, low breeding, and no recruitment were linked to fox predation and physical disturbance during monitoring. From 2014 to 2017, the colony was left undisturbed and monitored only by remote camera. Five adult animals were identified across this period (1 ♂ and 3 ♀s – all tagged; and one untagged female), and an average of 0.7 pouch young were birthed per tagged female per year. In 2019, camera-monitoring and non-invasive genetic monitoring (faecal) were used to identify colony members, genetic diversity, and breeding. Camera monitoring in 2019 identified the same five individuals, whereas genetic monitoring using 12 microsatellites identified eight individuals (two male and six female genotypes). Genetic diversity within the colony was moderate (expected heterozygosity (He) = 0.655, observed heterozygosity (Ho) = 0.854). Leaving the colony undisturbed after 2013 correlated with improved adult survival, increased breeding, and successful recruitment of young to the population. Recommendations for the Grampians colony include continuation of regular camera- and scat monitoring to improve our understanding of the reintroduction biology of P. penicillata and other marsupials in open, unfenced landscapes.
