Neo‐Taphonomic Analysis of Prey Bone Remains Accumulated by Golden Eagle (Aquila chrysaetos): A Case of Nests in Southern France

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...

Reconstructing Early Human Subsistence in Near Oceania: New Insights From Matenkupkum and Matenbek

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The colonization of New Ireland ~44–40,000 years ago represents the earliest evidence of human occupation in Near Oceania. Yet, the precise impacts of climatic changes on subsistence strategies during the Late Pleistocene, Last Glacial Maximum, and Holocene remain poorly understood.

Functional diversity in agricultural landscapes: evidence of long‐term clustering and multi‐scale effects of land use on avian communities

open access: yesOikos, EarlyView.
Functional diversity (FD) is an essential community property connecting biodiversity, ecosystem functioning, and conservation objectives. In agricultural landscapes, avian communities, which play key functional roles, are facing large‐scale biodiversity erosion, largely due to land‐use changes.

Effect of Environmental Enrichment on the Behavior and Welfare of Japanese Broilers at a Commercial Farm

open access: yesThe Journal of Poultry Science, 2015
The effect of hay bales and perches as environmental enrichment material was investigated on the behavior, heterophil/lymphocyte (H/L) ratio, footpad dermatitis (FPD), and productivity of Japanese broilers in a commercial farm.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

open access: yesOikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Impact of two telemetry transmitter implantation incision suturing methods on the physiological state and condition of perch (Perca fluviatilis)

open access: yesArchives of Polish Fisheries, 2017
The aim of this work was to determine the impact on European perch, Perca fluviatilis L. (mean body weight – 78.33 g) of the intraperitoneal implantation of telemetry transmitters using different suturing methods.

Fruit‐quality tradeoffs generate asymmetry in plant reliance on mutualistic frugivores

open access: yesOikos, EarlyView.
Seed dispersal is a fundamental ecological process influencing the evolution of plant life‐history strategies. In fleshy‐fruited plants dispersed by mutualistic frugivores, variation in fruit traits among closely related species may shape the temporal and spatial dynamics of dispersal events critical to population success.
