DiVert: A Global Database of Land Use and Management Effects on Local Vertebrate Abundance and Diversity

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 6, June 2026.
ABSTRACT Motivation Given that land use is a major driver of biodiversity loss worldwide, it is key to understand how different land use types and management practices affect biodiversity. Existing global databases on biodiversity responses to land use generally distinguish only broad land use types, focus on a wide taxonomic coverage at the expense of

Effect of Maxillary Expansion and Protraction in Class III Children on Quality of Life, Dentofacial and Upper Airway Characteristics: A Controlled Clinical Trial

open access: yesOrthodontics &Craniofacial Research, Volume 29, Issue 3, Page 481-489, June 2026.
ABSTRACT Objective To explore the relationship between early dentofacial orthopaedic treatment, improvement in the width of oropharynx and nasopharynx, and quality of life. Materials and Methods Thirty‐three prepubertal children with skeletal Class III (median age 9 years; 56% females) received treatment with a maxillary expander and facemask.
