Fatal Sarcocystis falcatula Infection in Three Penguins

Frontiers in Veterinary Science, 2019
Sarcocystis falcatula is a well-known cause of fatal pneumonia in some birds, particularly Old World psittacines. Here we describe fatal sarcosystosis due to S.

Genomic Structure and Demographic History of the Brown Fur Seal: From the Ice Age to Current Isolation

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Arctocephalus pusillus (the brown fur seal) has historically experienced population fluctuations associated with glacial cycles and anthropogenic exploitation. Previous mitochondrial DNA (mtDNA) and microsatellite analyses suggested a post‐glacial population expansion in A.

Stable Isotope Analysis of New Zealand Fur Seal Vibrissae Shows Deceased Juveniles Were Weaned Early

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
The New Zealand fur seal/kekeno (Arctocephalus forsteri, NZFS) is a marine predator native to Aotearoa/New Zealand. Little is known about its fine‐scale dispersal around New Zealand in the nonbreeding season. As an alternative to external marking or electronic tracking, stable isotope analysis was trialed to determine the origin of stranded (deceased ...

Fog, Symbiosis, and Survival: The Ecological Architecture of the Grit Crust From the Atacama Desert Represents a Lichen Holobiome Rather Than a Soil Microbiome

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Multi‐marker metabarcoding (16S rRNA, 18S rRNA, ITS2) of the fog‐dependent grit crust in the Atacama Desert reveals a community structured by lichen symbioses rather than typical soil‐derived microbial assemblages. The green algal photobiont Trebouxia dominates the eukaryotic community, accompanied by lichenized Caliciales and lichen‐associated ...

Partial migration in Magellanic penguins

Journal of Avian Biology
We studied the migration of Magellanic penguins near the southern tip of the breeding distribution, and for the first time found evidence of partial migration for this species within the same colony.

Computationally efficient Bayesian capture–mark–recapture models with transients, applied to survival of hand‐reared African Penguins

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1926-1937, June 2026.
Abstract Mark–recapture models are the primary framework for estimating demographic parameters in wild organisms. Complex life histories and sampling processes demand complex model formulations, yet these are vulnerable to errors in implementation and unanticipated biases.
