Dark diversity of flea (Siphonaptera) assemblages in South American rodents: Latitudinal and altitudinal gradients

Ecological Entomology, Volume 51, Issue 5, Page 983-992, October 2026.
The dark diversity of compound flea communities increased from north to south. The dark diversity of compound flea communities increased from lower to higher altitudes. The dark diversity of component flea communities also increased from north to south but did not vary with altitude.

Pathological and ecological host consequences of infection by an introduced fish parasite [PDF]

, 2011
The infection consequences of the introduced cestode fish parasite Bothriocephalus acheilognathi were studied in a cohort of wild, young-of-the-year common carp Cyprinus carpio that lacked co-evolution with the parasite.

Retroviral Infections Affect Survival and Clutch Size of Female Wild Turkeys

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigated the effects of two oncogenic retroviruses, lymphoproliferative disease virus (LPDV) and reticuloendotheliosis virus (REV), on survival and reproduction of wild turkeys in Maine. REV infection reduced female annual survival by nearly half, while LPDV‐infected hens laid fewer eggs, though other reproductive metrics were unaffected.

Waterbirds and Other Drivers of Endoparasite Communities Across a Hierarchy of Spatial Scales

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Understanding drivers of parasite community structure is compromised by poor sampling and historical focus on one host‐one parasite systems. Yet parasites are ubiquitous and co‐infections are common. This study aimed to identify how various drivers, ranging from landscape scale (waterbird movements, hydrological connectivity, region, host ...
