“…Although we recommend additional surveys to confirm the diet of L. etheridgei , we think that herbivory or an intermediate consumption of plant material is evident. There are several Liolaemus species with an intermediate consumption of plants: L. alticolor , L. jamesi , and L. signifier (Valencia et al, 1982 ; cited in Semhan et al, 2013 ), L. eleodori (Astudillo et al, 2015 ), L. pictus (Vidal & Sabat, 2010 ), L. polystictus (Olivera Jara & Aguilar, 2020 ), amongst others (see Abdala et al, 2012 ). Semhan et al ( 2013 ) point out the existence of a continuum between carnivory–omnivory–herbivory; accordingly, we suggest that L. etheridgei is not in any extreme but biased toward herbivory.…”

Regarding the tendency for herbivory, L. etheridgei would be a “widely foraging” species (Huey & Pianka, 1981 ) as it would need to move in order to reach plants.…”

“…We found this to be very helpful, however their classification of the omnivore (11–50% volumetric proportion of plant matter in the diet) and herbivore groups (70–100%) left an unclassified gap between 50 and 70% of plant matter, making the boundary between these two diet groups uncertain [ 37 ]. Subsequent studies adopted this classification adjusting omnivory to 11–50% and herbivory to > 50% [ 55 , 74 ], but we believe that in this arrangement, omnivory is underestimated and herbivory is overestimated. Therefore, we considered an insectivorous species when up to 10% plant matter was found in the stomach content, omnivory is better represented between 11 and 75% of plant matter, and that a fundamental plant diet (herbivorous) is > 75% [ 75 ].…”

“…Es uno de los dos géneros de lagartijas más diverso del mundo, con especies distribuidas en América del Sur, desde Tierra del Fuego hasta Perú (Etheridge, 1995); por tal motivo es un taxón ideal para el análisis de estrategias reproductivas de lagartijas en un contexto ambiental y filogenético. Para este género se han descripto diferentes patrones reproductivos que incluyen modalidades ovíparas y vivíparas con ciclos anuales, estacionales y bienales (Ramírez Pinilla, 1991a;Ramírez Pinilla 1994, 1995Cruz & Ramírez Pinilla, 1996;Ibargüengoytía & Cussac, 1996;Martori & Aún, 1997;Aun & Martori, 1998;Ibargüengoytía & Cussac, 1998;Vega & Bellagamba, 2005;Cánovas et al, 2006;Martori & Aun, 2010;Medina & Ibargüengoytía, 2010;Verrastro & Rauber, 2013;Semhan et al, 2013; entre otros), pero se desconoce aún el potencial reproductivo de la mayoría de las especies (Ávila et al, 2000).…”
