Throughout the underground regions of Thedas; full extent of distribution possibly spans the full area of the continent.
Nugs are primarly subterranean species, largely inhabiting the underground tunnels and cave systems occupied by Dwarven civilisation. However, nugs can be found on the surface predominantly in forested regions with accessible passageways into the subterranean realm.
Behaviour and ecology
Nugs are non-confrontational omnivorous species, preferring to hide and delve in the dark underground systems below the world of Thedas. Thus, nugs will typically avoid contact with people or predators by hiding in various crevices, using their pale skin to blend in with the surrounding rock faces. Reports of nugs in the wild demonstrate that nugs are remarkably inefficient at predator avoidance, despite their physiology; however, nug populations do not appear to suffer dramatically with predator presence, suggesting that either predators are too few to significantly impact population size or that alternative behaviours might allow them to rapidly bounce back from natural declines.
Given the lack of consistent light within their habitat, nugs are effectively blind, retaining only limited eyesight required for moving around above the surface. Nugs feed on a large variety of food sources, preferring insects but resorting to mineral deposits if available food resources are depleted. Their generalist diet may be one physiological trait that has allowed the nug to become some widespread and abundant historically.
Although the nug is a widespread and abundant species, they are heavily reliant on the connections of the Deep Roads to maintain connectivity and gene flow. With the gradual declination of Dwarven abundance and the loss of entire regions of the underground civilisation, it is likely that many areas of the nug distribution have become isolated and suffering from varying levels of inbreeding depression. Given the lack of access to these populations, whether some have collapsed since their isolation is unknown and potentially isolated populations may have even speciated if local environments have changed significantly.
Nugs are highly adapted to low-light, subterranean conditions, and show many phenotypic traits related to this kind of environment. The reduction of eyesight capability is considered a regression of unusable traits in underground habitats; instead, nugs show a highly developed and specialised nasal system. The high sensitivity of the nasal cavity makes them successful forages in the deep caverns of the underworld, and the elongated maw of the nug allows them to dig into buried food sources with ease. One of the more noticeable (and often disconcerting) traits of the nug is their human-like hands; the development of individual digits similar to fingers allows the nug to grip and manipulate rocky surfaces with surprising ease.
Re-establishment of habitat corridors through the clearing and revival of the Deep Roads is critical for both reconnecting isolated populations of nugs and restoring natural gene flow, but also allowing access to remote populations for further studies. A combination of active removal of resident Darkspawn and population genetics analysis to accurately assess the conservation status of the species. That said, given the commercial value of the nug as a food source for many societies, establishing consistent sustainable farming practices may serve to both boost the nug populations and also provide an industry for many people.
