Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

open access: yesEcological Entomology, Volume 51, Issue 4, Page 810-826, August 2026.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .

The highly rearranged mitochondrial genomes of the crabs Maja crispata and Maja squinado (Majidae) and gene order evolution in Brachyura

open access: yesScientific Reports, 2017
We sequenced the mitochondrial genomes of the spider crabs Maja crispata and Maja squinado (Majidae, Brachyura). Both genomes contain the whole set of 37 genes characteristic of Bilaterian genomes, encoded on both α- and β-strands.

Effect of Chitosan‐Alginate Polyelectrolyte Complex Formation and Multilayer Polymer Configuration on the Characteristics of 3D‐Printed Metronidazole‐Loaded Periodontal Films

open access: yesBiopolymers, Volume 117, Issue 4, July 2026.
The preparation and characterization of metronidazole loaded chitosan and alginate gels, followed by polyelectrolyte complex formation and 3D printing of multilayer periodontal films. ABSTRACT This study aimed to prepare six different metronidazole‐loaded film formulations by 3D printing for periodontal treatment.

Single‐cell sequencing reveals potential novel insights into appendage‐patterning and joint‐development in a spider

open access: yesDevelopmental Dynamics, Volume 255, Issue 7, Page 671-697, July 2026.
Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

Hunting Guild Mediates the Effects of Fecundity and Mortality on Sexual Size Dimorphism in Spiders

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Female red‐legged golden orb‐weaver (Trichonephila inaurata madagascarensis) with a much smaller male visible near the tip of the female abdomen, southwest Madagascar. Orb‐web weavers are characterised by relatively sedentary females occupying aerial orb webs and highly mobile mate‐searching males.

Trapped honey bees reduce floral visitation on milkweed flowers

open access: yesEcology, Volume 107, Issue 7, July 2026.
Abstract Trapped arthropods have been shown to benefit plants in several ways, but few studies have examined the potential costs of arthropod entanglement. Milkweeds (Asclepias spp.) have an unusual pollination system that requires relatively large packets of pollen (pollinia) to become attached to the appendages of insect pollinators and be pulled ...

On the morphological differentiation between Libinia spinosa and L. ferreirae (Crustacea: Brachyura: Majoidea: Epialtidae)

open access: yesZoologia (Curitiba), 2012
Libinia spinosa H. Milne Edwards in Guérin, 1832 and L. ferreirae Brito Capello, 1871, inhabit very similar environments, and their geographic and bathymetric distributions overlap for about 3000 km along the southwestern Atlantic.

Mithracinae (Decapoda: Brachyura) from the Brazilian coast: review of the geographical distribution and comments on the biogeography of the group

open access: yesNauplius
The geographical distribution of marine organisms, as a result of complex natural processes through geological time, has been changed, sometimes drastically, by species introductions.

Range extensions along western Atlantic for Epialtidae crabs (Brachyura, Majoidea) genera Acanthonyx Latreille, 1828 and Epialtus H. Milne Edwards, 1834

open access: yesNauplius
The present study provided information extending the known geographical distribution of three species of majoid crabs, the epialtids Acanthonyx dissimulatus Coelho, 1993, Epialtus bituberculatus H. Milne Edwards, 1834, and E.
