Indirect effects of primary prey population dynamics on alternative prey

open access: yes, 2014
We develop a theory of generalist predation showing how alternative prey species are affected by changes in both mean abundance and variability (coefficient of variation) of their predator's primary prey.

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Age structure, dispersion and diet of a population of stoats (Mustela erminea) in southern Fiordland during the decline phase of the beechmast cycle [PDF]

open access: yes, 2004
The dispersion, age structure and diet of stoats (Mustela erminea) in beech forest in the Borland and Grebe Valleys, Fiordland National Park, were examined during December and January 2000/01, 20 months after a heavy seed-fall in 1999.

Dynamic, Reconfigurable, and Hierarchical Biosynthetic Composites via Collagen Self‐Assembly within Highly Crowded Microgel Pastes

open access: yesAdvanced Materials, EarlyView.
A new approach to extracellular matrix‐mimetic, hierarchical biomaterials is presented. Soft gels composed of overpacked hydrogel microparticle arrays present a biomolecularly crowded environment permissive to the self‐assembly of collagen networks.

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

open access: yesAdvanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Feeding habits of stone martens in a Hungarian village and its surroundings [PDF]

open access: yes, 2003
The feeding habits of the stone marten (Martes foina) were studied by scat analysis in a village (n = 423 samples) and its surrounding agricultural environment (n = 572), during a six-year study (three periods), in southwest Hungary.

Feeding and foraging ecology of Trindade petrels Pterodroma arminjoniana during the breeding period in the South Atlantic Ocean [PDF]

open access: yes, 2017
Seabirds breeding in tropical environments experience high energetic demands, when foraging in an oligotrophic environment. The globally threatened Trindade petrel Pterodroma arminjoniana has its largest colony in Trindade Island (20°30′S–29°19′W) inside

Satellite Tracking of Adult and Immature Eastern Imperial Eagles

open access: yesПернатые хищники и их охрана, 2018
Four adult males, two adult females and two immature Imperial Eagles were trapped near Taif in Saudi Arabia close to the Red Sea while wintering. Three of theses eagles were trapped up to three times.

Using birds of prey to manage pest bird flocks under lethal and non-lethal conditions – A review

open access: yesRaptor Journal
Raptors have been successfully used to disperse and often control flocks of pest birds. However, the question that has not been resolved is, “If the raptor kills a small number of the target flock, does this improve the efficiency of control?” This mini ...

Behaviourally mediated predation avoidance in penguin prey: in situ evidence from animal-borne camera loggers [PDF]

open access: yesRoyal Society Open Science, 2018
Predator dietary studies often assume that diet is reflective of the diversity and relative abundance of their prey. This interpretation ignores species-specific behavioural adaptations in prey that could influence prey capture.
