Comparative Performance and Hemato-Biochemical Profile of Jinding Ducks in Different Production Systems of Bangladesh [PDF]

Pakistan Veterinary Journal, 2013
Jinding ducks are newly introduced to Bangladesh in commercial and household rearing. In order to assess production and hemato-biochemical status of Jinding ducks studies were conducted on household ducks of Chatkhil (August 2005-2006) and Sonagazi duck ...

Big Bird: A global dataset of birds in drone imagery annotated to species level

Remote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Accounting for animal movement during aerial imaging surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

How AI and Digital Technologies Can Enhance Sustainable Livestock Manure Management: An Overview From Treatment to Distribution

Sustainable Development, EarlyView.
ABSTRACT Sustainable livestock manure management sits at the nexus of climate, nutrient circularity and water quality. This review explores how artificial intelligence (AI) and digital platforms are used across four management stages, that is, treatment, storage, valorisation and distribution, and figures out where integration fails to deliver ...

Novel Highly Pathogenic Avian Influenza A(H5N6) Virus in the Netherlands, December 2017

Emerging Infectious Diseases, 2018
A novel highly pathogenic avian influenza A(H5N6) virus affecting wild birds and commercial poultry was detected in the Netherlands in December 2017. Phylogenetic analysis demonstrated that the virus is a reassortant of H5N8 clade 2.3.4.4 viruses and not

Rethinking Face‐to‐Face Interaction: Lessons from Studies of “Autistic Sociality”

Symbolic Interaction, EarlyView.
Face‐to‐face interaction is a foundational concept in microsociology. This article surveys the social experiences of autistic people, who are commonly known for having a strained relationship with interactions face to face. By interpretively reviewing and synthesizing the broader literature on “autistic sociality,” the article provides a nuanced ...

Contrastive Self‐Categorization as a Resource for Defending Cultural Stereotypes

Symbolic Interaction, EarlyView.
This study explores how speakers defend morally sanctionable cultural stereotypes from challenges in adult second language classrooms. Within the conversation analysis and membership categorization analysis frameworks, I examine two extended video‐recorded class discussions in which students maintain face‐threatening, stereotypical portrayals of ...
