Abstract Species diversity and morphological disparity are often linked, especially in lineages with evolutionary success. For invertebrates, their relation is poorly investigated, particularly under various ecochorological scales. Here, we explore thirteen assemblages of phytophagous scarab beetles (Coleoptera: Scarabaeidae) Sri Lanka infer patterns morphospace species along forest types, elevation zones sampling sites. Disparity body size shape was analysed based on 20 linear measurements, considering separately three major lineages: the entire assemblage two sister subclades, Sericini Pleurosticts excluding Sericini. Diversity were investigated sets landscape partitioning, from regional to local scale: type, zone locality. Results showed divergent at different geographical Morphospace divergence occupancy exhibited distinct patterns. Sericini, volume expressed by median centroid decreased increasing altitude. In contrast, demonstrated a more confined across types zones. However, similar not found for Shannon diversity. significantly correlated all chorological categories only assemblage, while this correlation recovered locality‐scale. Our results indicate that small changes linked alterations disparity, although significant shifts do necessarily correspond substantial change. Future research exploring genealogical aspect should incorporate phylogenetic framework, when comparing systematic levels.

Effects of organic amendments on crop production and soil fauna community in contrasting Zambian soils

Abstract The use of organic materials has been widely promoted to improve soil health. Surface‐active macrofauna serves as a key biological indicator health it supports agricultural productivity. However, the effects amendments on fauna and their relationships with crop production are still unknown in C‐limited conditions. A field experiment was conducted under different fertilizer management two soils contrasting C content (14.2/5.1 g kg −1 at Lusaka/Kabwe site) Zambia. Our results show contrast abundance soils. During experimental period, we collected total 926 individual all plots Lusaka site, while only 145 were Kabwe site. Soil predominantly composed Araneae, Coleoptera, Dermaptera, Diplopoda, Orthoptera. Organic significantly increased Coleoptera Diplopoda highly related yield. At effect amendment minimal, although higher yields observed amendment. These may be due nutrient water status between sites. findings suggest that site‐specific strategies required protect enhance communities C‐depleted
