Recent environmental change and biodiversity loss have modified ecosystems, altering disease dynamics. For wildlife health, this trend has translated into increased potential for disease transmission and reduced capacity to overcome significant population-level impacts, which may place species at risk of extinction. Thus, current approaches to wildlife health focus not on the absence of disease but rather on the concept of health promotion.

Article Synopsis
- - The vector responsible for diseases like dengue and Zika exhibits significant variability in its traits, influenced by environmental conditions, yet understanding this variability is complicated by the use of laboratory-bred populations instead of wild ones.
- - Using lab-adapted mosquito lines can lead to altered behavior and life history traits, making it crucial to involve field-collected populations in research to better reflect real-world conditions.
- - Semi-field studies, where wild mosquitoes are monitored under controlled yet ecologically relevant settings, are emerging as a valuable method to study the effects of larval environments on adult mosquitoes’ traits and behaviors.

Background: One Health (OH) is defined as a unifying approach aiming to sustainably balance and optimise the health of people, animals and the ecosystem. It recognises that the health of humans, animals (both domestic and wild), plants and the wider ecosystem are both interdependent and linked. As a concept, it aims to address complex problems requiring input from multiple disciplines.

The concept of a standardized reference diet (SRD) is used in laboratory model organisms to ensure nutritional control between studies and laboratories. Although models using the genetically identical, all female parthenogenetic marbled crayfish (Procambarus virginalis) are growing in popularity, research into nutrition in this species still has many knowledge gaps. To fast track the development of a SRD in terms of protein and amino acids (SRD) for this species, we first analyzed the composition of its body amino acids to determine the ideal protein concept (IPC) of indispensable amino acids in wild-caught P.

Article Synopsis
- Intraspecific biodiversity is crucial for the survival of species like Chinook salmon in changing environments, and this study used genetics and otolith data to examine their diversity in California's Yuba River.
- The study found that Yuba River salmon mostly consist of a significant percentage of local origin fish, although many non-native hatchery fish from nearby rivers also contributed to the population, raising concerns about genetic mixing and survival rates.
- It was observed that early-migrating fry were more dominant, but their survival rates appeared lower during drought years, underscoring the need for habitat restoration to improve growth conditions for salmon in the river.
