Influence of Seasonality on Habitat use and Spatial Distribution Patterns of Tree‐Dwelling Scorpion ( Physoctonus debilis ) in Brazilian Caatinga

André O. Silva-Júnior, Gabriel Luiz Celante, Stênio Ítalo Araújo Foerster, Matheus Leonydas Borba Feitosa et autres

Habitat selection plays a crucial role in the survival of various animals, primarily due to their ability to identify suitable sites for development. In Caatinga regions, climate seasonality has a strong effect on vegetation, consequently influencing the occurrence and spatial distribution of …

Plant genotypic diversity and defoliation jointly shape root exudation, fungal communities, and carbon and nitrogen cycling

Irene Cordero, Mathilde Chomel, Ellen L. Fry, Agnès Ardanuy et autres

Summary Intraspecific plant diversity is a major component of community diversity, yet its role in shaping plant–microbial interactions and soil functioning remains poorly understood. In particular, plant genotypic diversity may modulate ecosystem responses to defoliation, a key driver of ecosystem processes in …

Spatial Scale Modulates the Effect of Habitat Amount on Diversity Patterns of Arachnid Assemblages Across Different Brazilian Ecosystems

André Felipe de Araújo Lira, Adriano Medeiros DeSouza, Thayna R. Brito-Almeida, Hugo L. L. Neves et autres

ABSTRACT Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We …

Broad‐Scale Climatic Gradients Drive Multiple Facets of Scorpion Beta Diversity in Northeastern Brazil

Stênio Ítalo Araújo Foerster, André Felipe de Araújo Lira

ABSTRACT Aim Beta diversity analyses clarify mechanisms structuring ecological communities, but their multidimensional facets remain poorly explored in arthropods. Here, we quantified taxonomic, phylogenetic, and functional beta diversity in scorpions, partitioned these facets into species replacement and richness differences, and evaluated the …

Biomechanical trade-offs and the evolutionary dynamics of weapon morphology: phylogenetic comparative evidence from scorpion pincers

Stênio Ítalo Araújo Foerster

Pincer-like appendages are multifunctional structures that have evolved repeatedly within Arthropoda. In scorpions, they appear in the form of pedipalp chelae, providing an excellent example of form-function integration in evolutionary biology. Performance traits such as pinch force, closing speed, and mechanical resistance …

Complementary roles of agricultural and natural habitats in supporting moth diversity in semi-arid landscapes of Morocco

Nidal Fetnassi, Stênio Ítalo Araújo Foerster, Erki Õunap, Mohamed Ghamizi et autres

Human activities, particularly those exacerbated by climate change, are major drivers of biodiversity change. While many human actions degrade biodiversity, some anthropogenic habitats can provide refuges for certain species, insects in particular. Research on the human impact on biodiversity remains uneven both …

Biotic interactions rather than habitat complexity predict the occurrence of bark-dwelling social pseudoscorpions in urban environments

José Luís Costa, Stênio Ítalo Araújo Foerster, Vinicius Buregio Pessoa, Everton Tizo‐Pedroso et autres

Abstract The process of urbanization creates an environment that differs from natural habitats, resulting in changes in both habitats and biological interactions. This study assessed the ecological aspects of social pseudoscorpions associated with trees in urban environments. Specimens and habitat-descriptor variables were …

Forest clear‐cuts support diverse moth fauna but lack common grassland species

Kadri Ude, Stênio Ítalo Araújo Foerster, Nidal Fetnassi, Toomas Tammaru

Abstract Forests ecosystems sustaining most of the terrestrial biodiversity are under increasing anthropogenic pressure. Both the protection of the remaining natural forests and the mitigation of the negative effects of silviculture are of primary conservation concern. Clear‐cut areas are the main open …

Body size prediction in scorpions: a phylogenetic comparative examination of linear measurements of individual body parts

Stênio Ítalo Araújo Foerster

Body size has always been the focus of several ecological studies due to its undeniable influence on other life-history traits. The conventional representation of body size in arthropods typically relies on linear measures, such as total body length, or the length of …

Free Pasture of Exotic Goats Reduces Diversity and Negatively Affects Body Condition in Scorpions (Arachnida: Scorpiones) Assemblage From Brazilian Seasonal Dry Tropical Forest

Thayna R. Brito-Almeida, Stênio Ítalo Araújo Foerster, José Rivaldo de Lima, Meykson Alexandre da Silva et autres

Extensive grazing carried out freely by exotic goats represents an important source of anthropogenic degradation in seasonally dry tropical forests of Brazil. The presence of these herbivores may negatively impact the local fauna through the reduction of habitat complexity. In this study, …

A comparative study of body size evolution in moths: evidence of correlated evolution with feeding and phenology-related traits

Stênio Ítalo Araújo Foerster, John T. Clarke, Erki Õunap, Tiit Teder et autres

Interspecific variation in body size is one of the most popular topics in comparative studies. Despite recent advances, little is known about the patterns and processes behind the evolution of body size in insects. Here, we used a robust data set comprising …
