“…In fact, we found more genetic variation in the contemporary samples than historical ones, resulting in mixed results between time periods. Low levels of genetic diversity seem to be intrinsic to the life‐history traits of many raptors, as long generational times result in low mutation rates, large body size often reflects smaller net effective population sizes, and high dispersal power may result in homogenizing effects (Berlin et al., 2007; Martínez‐Cruz, 2011). For example, the Cinereous vulture ( Aegypius monachus ), the red kite ( Milvus milvus ), and the Spanish Imperial eagle ( Aquila adalberti ) exhibit one of the lowest mtDNA diversity levels with ≤ 10 haplotypes reported for the Control region (Martínez‐Cruz et al., 2007; Poulakakis et al., 2008; Roques & Negro, 2005), while California condors possess only three haplotypes (D'Elia et al., 2016).…”

Genetic diversity is widely recognized as centrally important for biodiversity assessment and conservation planning (Willoughby et al., 2015). Such focus is especially important when considering threatened and endangered species as they typically display low levels of genetic diversity, which can lead to reduced adaptive potential to environmental change (Bijlsma & Loeschcke, 2012). A common strategy to restore genetic diversity is the translocation of individuals to augment small and declining populations (Moritz, 1999; Whiteley et al., 2015). However, the motivation for restoring genetic diversity is often based on genetic surveys of modern populations, which assumes that past genetic diversity was always higher (Matocq & Villablanca, 2001; Napier et al., 2020). Nevertheless, long-term effects of translocations have been rarely assessed, and findings are inconsistent across systems: Some translocations have succeeded in increasing population fitness by incorporating new alleles (Johnson et al., 2010; Whiteley et al., 2015), while others have failed by

“…The field of conservation genetics investigates genetic processes, which affect populations of endangered species and identifies factors influencing the level of genetic diversity and distribution of genetic diversity among populations (Amos & Balmford 2001, Hedrick 2001, Sarre & Georges 2009, Kristensen et al 2010. Molecular techniques are applied to broaden our knowledge about biology, ecology, phylogeography and the taxonomy of endangered species (Haig et al 2011, Martinez-Cruz 2011. The results of such investigations may have important implications for the planning of conservation programmes and the management of the endangered populations of a wide range of species (e.g.…”

Knowledge about population size is of high importance for conservationists. We used non-invasively collected samples and microsatellite genotyping to estimate the size of the Tatra National Park population of the endangered capercaillie Tetrao urogallus. This population is one of the most important strongholds of the species in Poland. In 2016 over 150 samples (faeces and feathers) of the capercaillie were collected throughout area of the Tatra National Park. Then, DNA was extracted and genetic profiles were evaluated, using nine microsatellite markers. We obtained 81 reliable genotypes. Among them, 34 unique genotypes were found, corresponding to Minimum Number of individuals Alive in the investigated population. Application of capture-recapture models in the R package Capwire indicated, that the area was inhabited by approx. 54 birds, whereas regression model suggested presence of 36–64 individuals. Previous field surveys suggested that the number of birds in the Tatra National Park is about 50. Hence, we assumed that genetic tagging of non-invasive samples performs well in estimating the abundance of the capercaillie in the investigated population.

“…Among large long-lived birds, vultures provide a case study of certain extreme life history traits ( Van Overveld et al, 2020 ), so they may be excellent models to study the impact of environmental and demographic stochasticity, and to test predictions on contemporary and historical variation in neutral genetic diversity, population trends, and extinction risk. Despite vultures being one of the most threatened groups of birds, the information on genetic diversity of populations and species is still limited ( Godoy et al, 2004 ; Poulakakis et al, 2008 ; Martínez-Cruz & Camarena, 2018 ; Çakmak et al, 2019 ; Kleinhans & Willows-Munro, 2019 ; Davidović et al, 2020 ). As a consequence, there is a paucity of information on whether the interaction between life history traits, environmental features, and population characteristics can shape a genetic influence on the persistence and conservation of their populations.…”

Genetic signatures of population bottlenecks, relatedness, and inbreeding highlight recent and novel conservation concerns in the Egyptian vulture

The assessment of temporal variation in genetic features can be particularly informative on the factors behind demography and viability of wildlife populations and species. We used molecular methods to evaluate neutral genetic variation, relatedness, bottlenecks, and inbreeding in a declining population of Egyptian vulture (Neophron percnopterus) in central Spain. The results show that the genetic diversity remained relatively stable over a period of twelve years despite the decline in census and effective population sizes in the last decades. A relatively high proportion of nestlings from different and distant territories showed high relatedness in each study year. We also found support for an increasing impact of severe recent (contemporary) rather than distant (historical) past demographic bottlenecks, and the first evidence of inbred mating between full siblings coinciding with lethal malformations in offspring. The inbred nestling with feather malformations was positive to beak and feather disease virus recorded for the first time in this species. These results alert on recent and novel threats potentially affecting health and reducing the adaptive potential of individuals in this threatened species.
