“…Given that the introduction of cattle in California started back in the 18th century (Chamberlain et al, 2005), it is possible that, as in the case of the Atlantic Andean condors, the collapse of large marine mammal populations during industrial whaling in the 20th century (Rocha et al, 2014) triggered condor's extinction by pushing them into a direct conflict with farmers (Chamberlain et al, 2005;Lotze & Worm, 2009). Although the current recovery of marine mammal populations (Lotze et al, 2011) is a major step forward to re-establish condor populations in the coasts, for populations to be self-sustaining, conservation strategies need not only to enhance ecosystem protection (Kurle et al, 2016;Perrig et al, 2020), but also to include appropriate genetic management when considering breeding and translocation programs.…”

“…At the local level, the species is “Critically Endangered” in its northern distribution: Condors are functionally extirpated in Venezuela, <150 individuals inhabit Colombia, ~100 individuals inhabit at Ecuador, ~250 to 1,000 remain in Bolivia, and ~300 to 2,500 are estimated to occupy Peru (Méndez et al., 2019; Naveda‐Rodríguez et al., 2016; Piana & Angulo, 2015). In the southern part of its distributional range, Andean condors were extirpated from the steppe and the Atlantic coasts 100 years ago (Conway, 2005), but holdout in the high Andes (Lambertucci et al., 2018; Perrig et al., 2017, 2020). These extant populations continue to decline due to persistent poaching and habitat degradation, and face new challenges such as dietary toxins (especially lead and pesticides) and collisions with power lines (Alarcón & Lambertucci, 2018; Pavez & Estades, 2016; Wiemeyer et al., 2017).…”

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

“…However, population-level space use is underpinned by individuals that do not necessarily respond uniformly to environments with different habitat availability (Leclerc et al 2016). Habitat selection models are typically agnostic to these individual differences, even while a number of recent studies have explicitly highlighted their importance (e.g., Lesmerises and St-Laurent 2017;Montgomery et al 2018;Schirmer et al 2019;Perrig et al 2020). Given our understanding of functional responses to habitat selection and the importance of individual differences in habitat selection, we suggest there is a need to ascertain whether models based on the functional response should indeed improve our ability to forecast the distributions individual animals when they are faced with environmental change.…”

“…In particular, gap analysis has identified priority conservation areas for many taxa across the highly biodiverse Neotropics (e.g., de Carvalho et al 2017;Bax & Francesconi 2019;Perrig et al 2020). The harpy eagle (Harpia harpyja) is a large raptor historically distributed throughout Neotropical lowland tropical forest from southern Mexico to northern Argentina (Miranda et al 2019;).…”

Quantifying habitat use is important for understanding how animals meet their requirements for survival and provides useful information for conservation planning. Currently, assessments of range-wide habitat use that delimit species distributions are incomplete for many taxa. The harpy eagle (Harpia harpyja) is a raptor of conservation concern, widely distributed across Neotropical lowland forests, that currently faces threats from increasing habitat loss and fragmentation. Here, we use a logistic regression modelling framework to identify habitat resource selection and predict habitat suitability based on a new method developed from the International Union for the Conservation of Nature Area of Habitat range metric. From the habitat use model, we performed a gap analysis to identify areas of high habitat suitability in regions with limited coverage in the Key Biodiversity Area (KBA) network. Range-wide habitat use indicated that harpy eagles prefer areas of 70-75 % evergreen forest cover, low elevation, and high vegetation heterogeneity. Conversely, harpy eagles avoid areas of >10 % cultivated landcover and mosaic forest, and topographically complex areas. Our habitat use model identified a large continuous area across the pan-Amazonia region, and a habitat corridor from the Chocó-Darién ecoregion of Colombia running north along the Caribbean coast of Central America. Little habitat was predicted across the Atlantic Forest biome, which is now severely degraded. The current KBA network covered ∼18 % of medium to high suitability harpy eagle habitat exceeding the target representation (10 %). Four major areas of high suitability habitat lacking coverage in the KBA network were identified in the Chocó-Darién ecoregion of Colombia, western Guyana, and north-west Brazil. We recommend these multiple gaps of habitat as new KBAs for strengthening the current KBA network. Modelled area of habitat estimates as described here are a useful tool for large-scale conservation planning and can be readily applied to many taxa.
