“…Interestingly, populations resulting from the two distinct processes may be adaptively and demographically very different. Considering the prevalence of remnant groups in carnivore populations around the world [19][20][21][22][23][24][25][26][27][28][29], the ongoing recovery of many populations [64], and the increasing probability of range shifts, contractions and expansions related to climate change, we expect that neutral and adaptive evolutionary changes caused by recolonization and assimilation will be increasingly common.…”

Demographic mechanisms underpinning genetic assimilation of remnant groups of a large carnivore

Current range expansions of large terrestrial carnivores are occurring following human-induced range contraction. Contractions are often incomplete, leaving small remnant groups in refugia throughout the former range. Little is known about the underlying ecological and evolutionary processes that influence how remnant groups are affected during range expansion. We used data from a spatially explicit, long-term genetic sampling effort of grizzly bears (Ursus arctos) in the Northern Continental Divide Ecosystem (NCDE), USA, to identify the demographic processes underlying spatial and temporal patterns of genetic diversity. We conducted parentage analysis to evaluate how reproductive success and dispersal contribute to spatiotemporal patterns of genetic diversity in remnant groups of grizzly bears existing in the southwestern (SW), southeastern (SE) and east-central (EC) regions of the NCDE. A few reproductively dominant individuals and local inbreeding caused low genetic diversity in peripheral regions that may have persisted for multiple generations before eroding rapidly (approx. one generation) during population expansion. Our results highlight that individual-level genetic and reproductive dynamics play critical roles during genetic assimilation, and show that spatial patterns of genetic diversity on the leading edge of an expansion may result from historical demographic patterns that are highly ephemeral.

“…and dense scrub (Pistacia lentiscus, Quercus coccifera, Flueggea tinctorial), but also open pasture areas. This kind of habitat frequently supports high densities of rabbits, representing 80-99% of Iberian lynx diet [46], since it offers food, refuge, and a suitable structure for the lynx to hunt. Water availability is another essential component in Iberian lynx habitats, as they regularly visit water bodies [47].…”

Parasites of the Reintroduced Iberian Lynx (Lynx pardinus) and Sympatric Mesocarnivores in Extremadura, Spain

et al. 2021

The Iberian lynx (Lynx pardinus) is one of the most endangered felid species in the world. Conservation efforts have increased its population size and distribution and reinforced their genetic diversity through captive breeding and reintroduction programmes. Among several threats that the Iberian lynx faces, infectious and parasitic diseases have underlined effects on the health of their newly reintroduced populations, being essential to identify the primary sources of these agents and assess populations health status. To achieve this, 79 fresh faecal samples from Iberian lynx and sympatric mesocarnivores were collected in the reintroduction area of Extremadura, Spain. Samples were submitted to copromicroscopic analyses to assess parasite diversity, prevalence, and mean intensity of parasite burden. Overall, 19 (24.1%, ±15.1–35.0) samples were positive for at least one enteric parasite species. Parasite diversity and prevalence were higher in the Iberian lynx (43.8%) compared with the others mesocarnivores under study (e.g., the red fox Vulpes vulpes and the Egyptian mongoose Herpestes ichneumon). Ancylostomatidae and Toxocara cati were the most prevalent (15.6%) parasites. Obtained results revealed that Iberian lynx role as predator control might have reduced parasite cross-transmission between this felid and mesocarnivores due to their decreasing abundances. Surveillance programs must include regular monitoring of this endangered felid, comprising mesocarnivores, but also domestic/feral and wild cat communities.

“…The Iberian lynx (Lynx pardinus) is an Iberian endemic specialist predator, the wild rabbit (Oryctolagus cuniculus) being its staple prey (Fedriani et al 1999, Gil-Sánchez et al 2006. Its populations suffered a dramatic decrease during the 20th century, mainly due to human-mediated mortality, habitat destruction and transformation, and the decline of wild rabbit populations (Guzmán et al 2004).…”

Iberian lynx (Lynx pardinus) breeding in olive tree plantations

et al. 2016

View full text Add to dashboard Cite

At the turn of the 21st century, < 100 Iberian lynx (Lynx pardinus) individuals were found to occur in Southern Spain. Research conducted when the species was that scarce identified Mediterranean scrubland as its breeding habitat. In recent years, the population has grown both in number of individuals and occupied surface. Here, we describe the use of olive tree plantations with low scrub density as breeding habitats by the Iberian lynx. Our results suggest that habitats that were formerly considered as non-suitable, such as agricultural land, could indeed host Iberian lynx breeding territories in areas with low scrubland coverage if wild rabbits are abundant.
