Ecological and Statistical Perspectives on Host-Parasite Interactions in Cyprinus carpio

open access: yesAquatic Sciences and Engineering
This study investigates the parasite fauna of C. carpio inhabiting the Yenidal Irrigation Pond, focusing on temporal distribution patterns, host size-parasite load relationships, and the influence of water parameters on parasitic prevalence.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Prevalence of Helminthiasis Among African Elephants in Tsavo and Laikipia-Samburu Ecosystems, Kenya

open access: yesVeterinary Sciences
African elephants maintain a delicate balance between high intestinal helminth numbers and symptoms of poor health. However, calves and weaners face survival threats from damage caused by helminth infections and infestations during periods of starvation.

Comparative Analysis of Metal Preloading Technologies in Batteries and Capacitors

open access: yesEcoEnergy, EarlyView.
Metal preloading strategies play an important role in efficient batteries and hybrid capacitors to compensate for the consumed metals at the first discharge. This article reviews recent progress in preloading technologies in lithium‐ion and other metal‐ion systems.

Testimonial of ecological and biogeographic patterns: parasite assemblages of deep water catsharks (Pentanchidae) in Icelandic waters

open access: yesParasitology
Pentanchids (Elasmobranchii) are among the most species-rich groups of chondrichthyans. In the North Atlantic Ocean, the Icelandic catshark [Apristurus laurussonii (Saemundsson)], white ghost catshark (Apristurus aphyodes Nakaya & Stehmann), and mouse ...

Consumer diversity drives stronger predation in tropical marine communities

open access: yesEcography, EarlyView.
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

The Parasite that Causes Whirling Disease, \u3cem\u3eMyxobolus cerebralis\u3c/em\u3e, is Genetically Variable Within and Across Spatial Scales [PDF]

open access: yes, 2012
Understanding the genetic structure of parasite populations on the natural landscape can reveal important aspects of disease ecology and epidemiology and can indicate parasite dispersal across the landscape.
