The reduction in population genetic diversity due to inbreeding depression and the negative impact of human activity on habitats ultimately generates an extinction debt. Therefore, there is always a dire need to save wild population and to protect biodiversity. Preservation of wildlife female germplasm, i.e., oocytes and embryos, is a promising biotechnological tool to conserve species' biodiversity. Other applied tools of Assisted Reproductive Technology (ART) which assure conservation of endangered species include artificial insemination (AI), embryo transfer technology (ETT), and sperm cryopreservation. Only a few studies show the possibility of adapting the cryopreservation techniques developed for domestic animal female genetic material for use with wild animals. Difficulty is encountered in getting samples, accesses to animals for study, and the standardization of protocols for cryopreservation of such genetic material. Our meta-analysis of the literature (published or in press) and on-going studies found that biobanking for the preservation of vital tissues of wild animals is possible. Somatic tissue sections, ovarian tissues, sperms, oocytes and embryos are potential materials for preservation by vitrification. As vitrification is economical and easily applied, it appears to the best option currently available for the preservation of wildlife female genetics in order to conserve species' biodiversity.

Background: Tau proteins aggregate in a number of neurodegenerative disorders known as tauopathies. Various studies have highlighted the role of microtubule-binding domains in the intracellular aggregation of Tau protein.
Method: Using a library of synthetic VHHs humanized in collaboration with Hybrigenics, we have developed a number of anti-tau VHHs.

The TIRAP protein is an adaptor protein in TLR signaling which links TLR2 and TLR4 to the adaptor protein Myd88. The transcriptomic profiles of zebrafish larvae from a , and mutant and the corresponding wild type controls under unchallenged developmental conditions revealed a specific involvement of in calcium homeostasis and myosin regulation. Metabolomic profiling showed that the mutation results in lower glucose levels, whereas a mutation leads to higher glucose levels.

Food production does more damage to wild species than any other sector of human activity, yet how best to limit its growing impact is greatly contested. Reviewing progress to date in interventions that encourage less damaging diets or cut food loss and waste, we conclude that both are essential but far from sufficient. In terms of production, field studies from five continents quantifying the population-level impacts of land sharing, land sparing, intermediate and mixed approaches for almost 2000 individually assessed species show that implementing high-yield farming to spare natural habitats consistently outperforms land sharing, particularly for species of highest conservation concern.

Zoonotic and vector-borne infectious diseases are among the most direct human health consequences of biodiversity change. The COVID-19 pandemic increased health policymakers' attention on the links between ecological degradation and disease, and sparked discussions around nature-based interventions to mitigate zoonotic emergence and epidemics. Yet, although disease ecology provides an increasingly granular knowledge of wildlife disease in changing ecosystems, we still have a poor understanding of the net consequences for human disease.

The Red List Index (RLI) is an indicator of the average extinction risk of groups of species and reflects trends in this through time. It is calculated from the number of species in each category on the IUCN Red List of Threatened Species, with trends influenced by the number moving between categories when reassessed owing to genuine improvement or deterioration in status. The global RLI is aggregated across multiple taxonomic groups and can be disaggregated to show trends for subsets of species (e.
