The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Size matters: Natural experiments suggest the dear enemy effect is moderated by pack size in African wild dogs

open access: yesEcology and Evolution
Remote monitoring of communal marking sites, or latrines, provides a unique opportunity to observe undisturbed scent marking behaviour of African wild dogs (Lycaon pictus).

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

An Integrated Landscape of Fear and Disgust: The Evolution of Avoidance Behaviors Amidst a Myriad of Natural Enemies

open access: yesFrontiers in Ecology and Evolution, 2020
Fear of natural enemies in non-human animals is a concept dating back to the time of Darwin. Now recognized as a non-consumptive effect, the ecological and evolutionary impact of fear has been studied in a number of predator-prey systems within the last ...

Intraguild predation and competition impacts on a subordinate predator [PDF]

open access: yesOecologia, 2016
Intraguild (IG) predation and interspecific competition may affect the settlement and success of species in their habitats. Using data on forest-dwelling hawks from Finland, we addressed the impact of an IG predator, the northern goshawk Accipiter gentilis (goshawk), on the breeding of an IG prey, the common buzzard Buteo buteo.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

open access: yesPopulation Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

To Hunt or Patrol? Social Composition and Location Mediate Scent Marking Decisions of a Large Carnivore

open access: yesEcology and Evolution
While sociality is known to mediate territorial processes, it is less clear how sociality interacts with environmental features and neighbors' location to influence habitat selection and behavior.

Additive opportunistic capture explains group hunting benefits in African wild dogs

open access: yesNature Communications, 2016
African wild dogs hunt collaboratively over long distances in grassland plains. Hubel et al. use high-resolution GPS to show that in their remaining habitat of mixed woodland savannah, African wild dogs use multiple opportunistic short-distance hunts ...

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size
