Ocean depth modifies host-microbiome ecology and evolution

This study shows that ocean depth influences host-microbiome relationships, revealing different eco-evolutionary patterns in deep and shallow waters.

Pseudocryptic diversity within the Phakellia robusta species complex: description of Phakellia pallida sp. nov. and Phakellia pusilla sp. nov.

This study describes two new species within the Phakellia robusta species complex using morphological and molecular data, revealing pseudocryptic diversity and suggesting reassessment of previous species distributions.

Refining a molecular tool kit to capture tropicalization in Mediterranean Marine Protected Areas

The paper detects non-indigenous species in Mediterranean marine protected areas using eDNA and UVC, finding that aqueous eDNA metabarcoding provides the most comprehensive species list.

Independent origins of spicules reconcile palaeontological and molecular evidence of the evolutionary history of sponges

The paper reconciles molecular and fossil evidence by showing sponges emerged in the early Ediacaran without spicules, which evolved independently multiple times later.

ERGA-BGE genome of Stigmatoteuthis arcturi Robson, 1948: the jewelled squid

The paper presents the chromosome-level genome assembly of Stigmatoteuthis arcturi, providing insights into the evolutionary biology of deep-sea squids.

The archaeal class Nitrososphaeria is a key player of the reproductive microbiome in sponges during gametogenesis

This study investigates microbial changes in sponge reproductive stages, finding that Nitrososphaeria archaea are significantly associated with microbial composition shifts in species with previtellogenic oocytes.

Spatial and seasonal biodiversity variation in a large Mediterranean lagoon using environmental DNA metabarcoding through sponge tissue collection

The paper assesses faunal composition and its spatial and temporal variation in a Mediterranean lagoon using eDNA metabarcoding from sponge tissues collected in different seasons and areas.

Genomic connectivity and adaptation signals of the freshwater sponge Ephydatia muelleri across its distribution

This study examines genetic connectivity and adaptation in Ephydatia muelleri across its range using ddRADseq data, finding low connectivity and polygenic adaptation to environmental factors.

ERGA-BGE genome of the Spanish Moon Moth Graellsia isabellae Graells, 1849: a nocturnal lepidopteran protected by the Habitats Directive

The paper presents the reference genome of the Spanish Moon Moth Graellsia isabellae, which helps resolve its scientific name and supports genetic monitoring of the species.

Optimised DNA isolation from marine sponges for natural sampler DNA (nsDNA) metabarcoding

This study optimises DNA isolation from marine sponges for metabarcoding, finding that blotting tissue dry and using a non-commercial protocol improves taxon recovery and sequence reads.

Warm Temperatures, Cool Sponges: The Effect of Increased Temperatures on the Antarctic Sponge Isodictya sp.

This study investigates how the Antarctic sponge Isodictya sp. responds to acute heat stress by exposing it to 3 and 5°C, finding limited molecular response variation despite temperature increases.

Trimitomics: An efficient pipeline for mitochondrial assembly from transcriptomic reads in non-model species

The paper introduces a pipeline for efficiently assembling mitochondrial genomes from transcriptomic reads in non-model species, demonstrating its effectiveness across diverse invertebrates.

Delegating sex: differential gene expression in stolonizing syllids uncovers the hormonal control of reproduction in Annelida

The paper identifies differentially expressed genes and neurohormones involved in stolonization in Syllis magdalena, suggesting hormonal and circadian regulation of reproduction in annelids.

Ancestrally Shared Regenerative Mechanisms Across the Metazoa: A Transcriptomic Case Study in the Demosponge Halisarca caerulea

This paper presents a transcriptomic analysis of the demosponge Halisarca caerulea, identifying Wnt pathways and other genes involved in regeneration and providing a reference transcriptome for future studies.
