Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades
Oikos, EarlyView.Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.

Oikos, EarlyView.Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

On the record of Coronula diadema (Cirripedia: Coronulidae) in Chilean waters
GayanaThe barnacle genus Coronula Lamarck, 1802 (Cirripedia: Coronulidae) includes two extant species: Coronula diadema (Linnaeus, 1767), and Coronula reginae Darwin, 1854. These rather large, and highly specialized barnacles, live exclusively attached to the

Migrating eastern North Pacific gray whale call and blow rates estimated from acoustic recordings, infrared camera video, and visual sightings. [PDF]
, 2019 During the eastern North Pacific gray whale 2014-2015 southbound migration, acoustic call recordings, infrared blow detections, and visual sightings were combined to estimate cue rates, needed to convert detections into abundance. The gray whale acoustic

Oikos, EarlyView.Capture–recapture (CR) models have been used for decades to estimate population size and demographic rates in natural populations from the monitoring of individuals. One of the most frequent deviations from assumptions required in CR studies is the immediate trap‐dependence that corresponds to the correlation between capture events. We review empirical

The Truth About Soviet Whaling [PDF]
, 2008 I have always condemned (and to do anything more was not within our power or abilities) the illegal and sometimes destructive whaling by the Soviet Union.
