A compendium and comparative epigenomics analysis of cis-regulatory elements in the pig genome por Yunxia Zhao, Ye Hou, Yueyuan Xu, Yu Luan, Huanhuan Zhou, Xiaolong Qi, Mingyang Hu, Daoyuan Wang, Zhangxu Wang, Yuhua Fu, Jingjin Li, Saixian Zhang, Jianhai Chen, Han Jianlin, Xinyun Li, Shuhong Zhao

“…Although major advances in genomics have initiated an exciting new era of research, a lack of information regarding cis-regulatory elements has limited the genetic improvement or manipulation of pigs as a meat source and biomedical model. Here, we systematically characterize cis-regulatory elements and their functions in 12 diverse tissues from four pig breeds by adopting similar strategies as the ENCODE and Roadmap Epigenomics projects, which include RNA-seq, ATAC-seq, and ChIP-seq. …”

Zoonoses (Project 1): Wildlife/domestic livestock interactions por Jones, B., McKeever, Declan J., Grace, Delia, Pfeiffer, Dirk U., Mutua, Florence K., Njuki, Jemimah, McDermott, John J., Rushton, Jonathan, Said, Mohammed Yahya, Ericksen, Polly J., Kock, R., Alonso, Silvia

“…Spatial relationships between important zoonoses and land use and human population density were explored. A systematic review was carried out focussing on: disease transmission routes, risk factors for disease transmission, drivers of wildlife-livestock interactions, pathogens of wildlife capable of recombining with organisms in livestock, wildlife species that are potential sources of zoonotic pathogens, production and socio-economic factors influencing the risk of transmission, and risk management and control interventions.…”

Securing nature’s contributions to people requires at least 20%–25% (semi-)natural habitat in human-modified landscapes por Mohamed, Awaz, DeClerck, Fabrice A.J., Verburg, Peter H., Obura, David, Abrams, Jesse F., Zafra-Calvo, Noelia, Rocha, Juan, Estrada-Carmona, Natalia, Fremier, Alexander, Jones, Sarah K., Meier, Ina C., Stewart-Koster, Ben

“…Conservation efforts often prioritize safeguarding specific species, habitats, or intact ecosystems but overlook biodiversity’s fundamental role in providing Nature’s Contributions to People (NCP) in human-modified landscapes. Here, we systematically review 154 peer-reviewed studies to estimate the minimum levels of (semi-)natural habitat quantity, quality, and spatial configuration needed in human-modified landscapes to secure functional integrity essential for sustaining NCP provision. …”
