Bionomics of the pied stilt (Himantopus leucocephalus) in New Zealand : with special reference to breeding behaviour: a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]

open access: yes, 1971
Aims of the Study. Although the Pied Stilt, Himantopus h.leucocephalus, Gould,1837*Nomenclature for New Zealand birds follows that laid down in the Annotated Checklist of the Birds of New Zealand (Kinsky,1970). Other bird species are as prescribed in the

Provenance does matter: links between winter trophic segregation and the migratory origins of European robins [PDF]

open access: yes, 2016
Amongst migratory species, it is common to find individuals from different populations or geographical origins sharing staging or wintering areas.

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

open access: yesAdvanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

The decline of ground nesting birds in Europe: Do we need to manage predation in addition to habitat?

open access: yesGlobal Ecology and Conservation
Bird populations are declining globally with losses recorded in many European breeding birds. Habitat management measures have not resulted in widespread reversal of these declines. We analysed national bird population trends from ten European countries (

Multiple components of environmental change drive populations of breeding waders in seminatural grasslands [PDF]

open access: yes, 2018
Environments are rapidly changing due to climate change, land use, intensive agriculture, and the impact of hunting on predator populations. Here, we analyzed longterm data recorded during 1928–2014 on the size of breeding populations of waders at two ...

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

open access: yesAdvanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Potential of pest regulation by insectivorous birds in Mediterranean woody crops.

open access: yesPLoS ONE, 2017
Regulation of agricultural pests managing their natural enemies represents an alternative to chemical pesticides. We assessed the potential of insectivorous birds as pest regulators in woody crops located in central Spain.

Nurr1 Orchestrates Claustrum Development and Functionality

open access: yesAdvanced Science, EarlyView.
Nurr1 (Nr4a2) is the master transcription factor to control claustrum morphogenesis and cell fate decision postmitotically by inhibiting intracellular G‐protein signaling. Nurr1 deficiency alters the transcriptomic profiles of subcortical claustral neurons into neocortical insular neurons, resulting in defected claustrum development, impaired axonal ...

New Evidence on the Linkage of Population Trends and Species Traits to Long-Term Niche Changes

open access: yesBirds, 2022
Despite the assessment of long-term niche dynamics could provide crucial information for investigating species responses to environmental changes, it is a poorly investigated topic in ecology. Here, we present a case study of multi-species niche analysis

Reproductive consequences of natal dispersal in a highly philopatric seabird [PDF]

open access: yes, 2017
Natal and breeding dispersal have a major impact on gene flow and population structure. We examined the consequences of natal dispersal on the reproductive success (proportion of pairs rearing chicks) of colonial-breeding Thick-billed murres (Uria lomvia)
