Winter diet of the long-eared owl Asio otus (Strigiformes: Strigidae) in the grasslands of Janos, Chihuahua, Mexico
Revista Chilena de Historia Natural - - 2017
José I. González-Rojas, Hernaldo Padilla-Rangel, Irene Ruvalcaba-Ortega, Miguel A. Cruz-Nieto, Ricardo Canales-del-Castillo, Antonio Guzmán-Velasco
The long-eared owl (Asio otus) has a Holarctic distribution, including much of North America. This nocturnal species is considered to be extremely secretive, and poorly known in the Great Plains of the United States and Canada, as well as to México, where no previous studies on its diet have been conducted. We analyzed 120 pellets collected during January 2007 in roosts in a 2–3 m height mesquite ...... hiện toàn bộ
Latitudinal diversity patterns of Chilean coastal fishes: searching for causal processes
Revista Chilena de Historia Natural - Tập 87 - Trang 1-11 - 2014
Arturo H Navarrete, Nelson A Lagos, F Patricio Ojeda
Several particular aspects of diversity patterns of Chilean littoral fishes are still poorly understood, and existing studies within this scope are fundamentally based on bibliographic compilations. In this study, we use empirical data to assess whether the diversity patterns of fish fauna along 4000 km of the Chilean coast (20°–55° S)can be explained in relation to the environmental latitudinal g...... hiện toàn bộ
The microbial world in a changing environment
Revista Chilena de Historia Natural - Tập 94 - Trang 1-5 - 2021
Rafael Vicuña, Bernardo González
In this article we would like to touch on the key role played by the microbiota in the maintenance of a sustainable environment in the entire planet. For obvious reasons, this article does not intend to review thoroughly this extremely complex topic, but rather to focus on the main threats that this natural scenario is presently facing. Recent literature survey. Despite the relevance of microorgan...... hiện toàn bộ
Assessment of intestinal parasites in the coexisting Bombus terrestris (Apidae) and Xylocopa augusti (Apidae) in central Chile
Revista Chilena de Historia Natural - Tập 93 - Trang 1-6 - 2020
Kiara Fernández, Jennifer Alcaíno, Dionisia Sepúlveda, Rodrigo Medel
Bombus terrestris is a European bumblebee extensively commercialized worldwide for crop pollination. In Chile, this species was introduced in 1997 and after confinement escape, it has spread and established in several localities of central-southern Chile and in the Argentine Patagonia. The South American carpenter bee Xylocopa augusti, in turn, has been recently reported in central Chile, and as B...... hiện toàn bộ

Prosopis tamarugo Phil.: a native tree from the Atacama Desert groundwater table depth thresholds for conservation
Revista Chilena de Historia Natural - Tập 88 - Trang 1-8 - 2015
Gabriela Calderon, Marco Garrido, Edmundo Acevedo
Prosopis tamarugo Phil. is a legume tree native to the Atacama Desert, Chile. Tamarugo has physiological characteristics that are highly adapted to extreme life conditions in the Pampa del Tamarugal. Null precipitation makes tamarugo completely dependent on groundwater, developing in areas where the groundwater depth is closest to the surface. Groundwater extraction for do...... hiện toàn bộ
Host plant specificity of the moth species Glena mielkei (Lepidoptera, Geometridae) in northern Chile
Revista Chilena de Historia Natural - Tập 87 - Trang 1-4 - 2014
Felipe Méndez-Abarca, Camila F Méndez, Enrique A Mundaca
Host plant specificity refers to the preference of insects for particular plant species that allow them to complete their life cycle. Moth species of the Geometridae family depend closely on the vegetation composition to complete their life cycles. In northern Chile, the Geometridae species Glena mielkei is the only species described of the genus Glena. So far, this species has only been associate...... hiện toàn bộ
Temporal and spatial variation of the pollinator assemblages in Alstroemeria ligtu (Alstroemeriaceae)

Nest building and description of parental care behavior in a temperate reef fish, Chromis crusma (Pisces: Pomacentridae)
Revista Chilena de Historia Natural - Tập 87 - Trang 1-9 - 2014
Teresa Navarrete-Fernández, Mauricio F Landaeta, Claudia A Bustos, Alejandro Pérez-Matus
Subtle ecological and behavioral mechanisms that enhance reproduction such as nest building by animals may provide useful information of population level processes. Variation in behavioral traits may be observed as phenotypic traits that are shaped by sexual and natural selection. Using ecological sampling of benthic substrata and underwater video recordings, we assessed nest-building behavior thr...... hiện toàn bộ
Rare, Endangered and Threatened (RET) climbers of Southern Western Ghats, India
Revista Chilena de Historia Natural - Tập 89 - Trang 1-5 - 2016
Ariyan Sarvalingam, Arumugam Rajendran
The Mountains of the Western Ghats are the second most important shelter in the world for threatened species. The current paper is an attempt to study the conservation assessment of rare, endangered and threatened species (RET) of the southern Western Ghats. A species is endangered when it is threatened with extinction. Since time began, countless species have gone extinct from natural processes. ...... hiện toàn bộ
