“…Species of the genus Cyclocephala are common visitors to radially symmetrical flowers and consume the fruits of a wide variety of plants. It has been reported that the reproduction of species in this genus is linked to the flowering period, and their presence in Annonaceae flowers can significantly contribute to pollination (Costa et al, 2017; Gottsberger & Webber, 2018; Saravy et al, 2022).…”

Owing to the rapid and ongoing anthropogenic changes impacting ecosystem functions and their interplay with biodiversity, there is a growing focus on assessing insect functional diversity. This emphasis helps to unravel key roles of insects on ecosystem processes and to identify the assembly mechanisms that regulate species coexistence. The ecological functions of phytophagous scarab beetles (Scarabaeidae) have been relatively unexplored, and potential functional traits are scattered throughout the literature. Species within this group exhibit diverse lifestyles, forms and sizes. They exploit various resources such as decomposing wood, foliage, roots and flowers, with a small subset identified as predators. Although many of their representatives are significant agricultural pests, information on their contributions in natural ecosystems has not been consolidated. This study reviews the ecological functions potentially carried out by phytophagous scarab beetles and proposes functional traits to be incorporated into studies of functional diversity. Through this, the goal is to integrate the scattered information, stimulate the generation of questions that go beyond classical ecological theory and contribute to advancing our knowledge of their ecosystem functions, as well as the foundations for understanding community structure. We propose to use trophic groups to define functions such as bioturbation, organic matter decomposition, biological control and potential pollination. A simplified list of functional traits was obtained by conducting correlation analyses using a trait matrix from a region in northern Colombia. This represents a significant advance for the study of traits within the framework of functional ecology, applicable to territorial planning and biodiversity conservation.

Background Understanding morpho-genetic diversity and differentiation of species with relatively large distributions is crucial for the conservation and sustainable management of their genetic resources. The present study focused on Annona senegalensis Pers., an important multipurpose wild plant, distributed exclusively in natural ecosystems but facing several threats. The study assessed the genetic and morphological diversity, structure, and differentiation of the species in populations from Western (Benin) and Southern (Mozambique) Africa. The material was evaluated to ascertain the environmental (climatic) determinants of the variation within this species. Methods Four sub-populations comprised of 154 individuals were phenotyped based on nineteen plant, fruit, and leaf morphological traits and further genotyped using ten polymorphic nuclear microsatellite (nSSR) markers. Results The results indicated strong differences in plant, fruit, and leaf morphological traits between Western and Southern populations. Furthermore, the studied populations were characterized by high genetic diversity, with an average genetic diversity index of 1.02. Western populations showed higher heterozygosity values (0.61–0.71) than Southern populations (0.41–0.49). Western and Southern populations were clearly differentiated into two different genetic groups, with further genetic subdivisions reflecting four sub-populations. Genetic variation between regions (populations) was higher (69.1%) than among (21.3%) and within (9.6%) sub-populations. Four distinct morphological clusters were obtained, which were strongly associated with the four genetic groups representing each sub-population. Climate, mainly precipitation and temperature indexes, explained the relatively higher variation found in morphological traits from Western (40.47%) in relation to Southern (27.98%) populations. Our study suggests that both environmental and genetic dynamics play an important role in the development of morphological variation in A. senegalensis.
