Seroprevalence and Risk Analysis of Toxoplasma Gondii in Wild Birds of District Lahore Punjab, Pakistan

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study found that over 10% of wild birds in Lahore, Pakistan, carry antibodies for Toxoplasma gondii, a parasite that can cause serious illness in humans and animals. Birds like lapwings and silver bills showed especially high antibody rates. Improved monitoring is needed to better understand risk dynamics in Pakistan.

Integumentary fibrosarcoma in a free‐living swan (Cygnus olor): Medical and welfare considerations

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract A 10‐kg adult male mute swan (Cygnus olor) of unknown age was admitted for investigations of two large ventral masses overlying the keel bone, which were discharging purulent material. The masses measured 8.9 × 2.1 cm and 4.2 × 3.2 cm. Empirical treatment with non‐steroidal anti‐inflammatory drugs and antimicrobials was instigated.

DIY: A Practical Field‐to‐Sequencer Workflow for Metabarcoding the Diet of Terrestrial Carnivore Species

Molecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Metabarcoding of faecal samples is a powerful, non‐invasive approach for investigating the feeding ecology of carnivores, revealing prey diversity and unexpected dietary components with greater resolution than traditional methods. However, the approach remains technically demanding, as challenges and potential biases arise at every stage, from

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

Journal of Anatomy, Volume 248, Issue 5, Page 830-842, May 2026.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Rickettsial infection in ticks infesting wild birds from two eco-regions of Argentina

Revista Brasileira de Parasitologia Veterinária
Several tick-borne Rickettsia species are recognized human pathogens in Argentina. Here we evaluated rickettsial infection in ticks collected on passerine birds during 2011-2012 in two eco-regions of Argentina.

Multidirectional chromosome painting in Synallaxis frontalis (Passeriformes, Furnariidae) reveals high chromosomal reorganization, involving fissions and inversions

Comparative Cytogenetics, 2018
In this work we performed comparative chromosome painting using probes from Gallus gallus (GGA) Linnaeus, 1758 and Leucopternis albicollis (LAL) Latham, 1790 in Synallaxis frontalis Pelzeln, 1859 (Passeriformes, Furnariidae), an exclusively Neotropical ...

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, Volume 248, Issue 5, Page 873-887, May 2026.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Metamorphosis and lncRNAs: A Close Relationship

genesis, Volume 64, Issue 2, April 2026.
ABSTRACT The classical definition of metamorphosis is a post‐embryonic transformation, such as from a tadpole to a froglet. However, recent studies suggest this process occurs to some degree in all vertebrates, as the underlying endocrine and molecular pathways are highly conserved. With the advent of high‐throughput sequencing, transcriptomic data for
