Species inventory and morphological measurements of spiders (Arachnida, Araneae) and ants (Insecta, Hymenoptera, Formicidae) collected in northern Ghana. Biodiversity Data Journal, 14, e163267. https://doi.org/10.3897/BDJ.14.e1632671314-2836http://hdl.handle.net/10400.3/8852ABSTRACT: Agricultural expansion, a leading driver of biodiversity loss, has widespread effects on ecosystem services, particularly in tropical regions. In West Africa, the impact of intensified agriculture on local biodiversity – especially predator and decomposer species like spiders and ants – is understudied. This study aims to provide a checklist of terrestrial spiders and ants associated with savannahs and mango orchards in northern Ghana thus creating a baseline for further ecological studies on the community composition of these groups.engagriculturebiodiversitychecklistmango orchardmorphometricsstandardised samplingWest AfricaWest Sudanian savannahdata paper10.3897/BDJ.14.e1632671314-2828
