The caribou ( sspp.) is a keystone wildlife species in northern ecosystems that plays a central role in the culture, spirituality and food security of Indigenous People. The Arctic is currently experiencing an unprecedented rate of climate change, including warming temperatures and altered patterns of precipitation.

Delving into knowing the blackfly (Diptera: Simuliidae) species composition of Spain and their ecological requirements is crucial, due to their instrumental role in natural food webs as intermediaries in the flow of energy in aquatic ecosystems, and because of the haematophagic behaviour displayed by females of several species. The present study has analysed the abundance and distribution of the larvae and pupae of blackfly species in 105 sampling stations located in lotic water bodies of the provinces of Ávila, Salamanca, and Zamora of the Tormes River basin. The study has allowed to identify 24 species: 17 from Ávila, 13 from Salamanca, and seven from Zamora, classified in three genera (Metacnephia, Prosimulium, and Simulium), and five subgenera (Boophthora, Eusimulium, Nevermannia, Simulium, Wilhelmia).

Black flies (Diptera: Simuliidae) are significant pests and vectors transmitting pathogens to humans and other animals. However, knowledge of species diversity as well as their role as pests and vectors in Laos is limited, despite the country having abundant suitable lotic habitats, that is, running water. In this study, we collected wild adult black fly specimens from Laos.

The black soldier fly larvae (BSFL) is a highly valued resource insect, renowned for its efficient and eco-friendly approach to the treatment of organic waste. A crucial matter that demands clarification is whether the heavy metals are eliminated or remain within BSFL bodies. Our research focused on the toxicokinetic and the dynamic tissue changes of cadmium (Cd) in BSFL exposed to low (50 mg/kg), moderate (300 mg/kg), and high levels (700 mg/kg) of Cd stress, with the goal of offering a novel perspective on this matter.

- Sibling species within bloodsucking black flies complicate the assessment of biodiversity and the species' roles in spreading pathogens, prompting research on molecular genetic structures of Simulium reptans in Russia and Northern Kazakhstan.
- Genetic analysis revealed distinct mitochondrial DNA variants, identifying two forms: S. reptans A in Northern Europe and S. reptans B in Siberia and Northern Kazakhstan, along with three branches of S. reptans B based on geographic distribution.
- The study suggests the need for further research in mountainous regions of Eurasia to better understand the ecological adaptations and distribution of these black fly forms.
