| a review of chilean chiggers (acari: trombiculidae), with the description of a new genus and ten new species. | a new genus and species of chigger mites, diaguitacarus choapensis gen. et sp. nov., is described from four lizard species of the genus liolaemus in choapa province of chile. eight new chigger species are described from lizards of the genera liolaemus, phymaturus (squamata: liolaemidae), and microlophus (squamata: tropiduridae), in arica and parinacota, atacama, coquimbo, valparaíso, and biobío regions: eutrombicula nerudai sp. nov., eutrombicula mistrali sp. nov., eutrombicula picunche sp. nov. ... | 2015 | 26249418 |
| a new species of ornithodoros (acari: argasidae), parasite of microlophus spp. (reptilia: tropiduridae) from northern chile. | a new species, ornithodoros microlophi (acari: argasidae), belonging to the subgenus alectorobius is described from larvae collected on the lizards microlophus atacamensis (donoso-barros, 1966) and microlophus quadrivittatus (tschudi, 1845) (squamata: tropiduridae) in continental and insular localities from northern chile. larvae of o. microlophi can be distinguished from other neotropical species of the genus ornithodoros by a combination of the following characters, namely 10 pairs of ventral ... | 2013 | 23219344 |
| one solution for two challenges: the lizard microlophus atacamensis avoids overheating by foraging in intertidal shores. | in lizards, one of the most important behavioral mechanisms to cope with spatial and temporal variations in thermal resources observed is activity time. the longer a lizard can maintain activity, the more time it has to forage and reach larger adult body size. we studied the behavioral adjustments to different climatic regimens on daily and seasonal scales in three natural populations of the lizard microlophus atacamensis along a latitudinal temperature and rainfall gradient. we also used niche ... | 2014 | 24839969 |
| geographical variation in the use of intertidal rocky shores by the lizard microlophus atacamensis in relation to changes in terrestrial productivity along the atacama desert coast. | 1. the movement of materials and organisms between ecosystems is a common process in nature. 2. in the present study we investigate the hypothesis that the movement of consumers between ecosystems depends not only on the differences in productivity between ecosystems and prey availability, but also on these animals' biological characteristics. 3. to address this hypothesis we investigated the changes in abundance, habitat utilization and diet of the lizard microlophus atacamensis along its geogr ... | 2008 | 18416712 |
| data on metal accumulation in the tails of the lizard microlophus atacamensis in a coastal zone of the atacama desert, northern chile: a non-destructive biomonitoring tool for heavy metal pollution. | in this data article, we investigated the accumulation of heavy metals in the lizard microlophus atacamensis, in three coastal areas of the atacama desert, northern chile. we captured lizards in a non-intervened area (parque nacional pan de azucar, paz), an area of mining impact (caleta palitos, pal) and an active industrial zone (puerto de caldera, cal). our methods included a non-lethal sampling of lizard's tails obtained by autotomy. the concentrations of lead, copper, nickel, zinc and cadmiu ... | 2020 | 32775559 |
| geometric morphometric analysis of the head of microlophus atacamensis (tropiduridae) in a latitudinal gradient. | clinal variation is defined as gradual variation in a character associated with geographic distance among sites. microlophus atacamensis is a medium large lizard species which inhabits the intertidal zone of northern chile, distributed from antofagasta (23° 39' s) to arrayán, la serena (29° 41' s) in a gradient which could show clinal variation. geometric morphometrics analyzes differences in shape independent of size; information about shape allows a more complete biological interpretation than ... | 2015 | 31966111 |
