CYTOGENETIC STUDY IN SAND SPIDERS (SICARIIDAE) FROM THE BRAZILIAN CAATINGA: SEX CHROMOSOME SYSTEM DIVERSITY IN CLOSELY RELATED SPECIES [PDF]

BAG. Journal of Basic and Applied Genetics, 2022
In this study, we investigated the chromosomes of three species of Sicarius spiders from the Brazilian Caatinga, using classical and molecular cytogenetic techniques.

Predatory Organisms with Untapped Biosynthetic Potential: Descriptions of Novel Corallococcus Species C. aberystwythensis sp. nov., C. carmarthensis sp. nov., C. exercitus sp. nov., C. interemptor sp. nov., C. llansteffanensis sp. nov., C. praedator sp. nov., C. sicarius sp. nov., and C. terminator sp. nov. [PDF]

Appl Environ Microbiol, 2020
Corallococcus spp. are common soil-dwelling organisms which kill and consume prey microbes through the secretion of antimicrobial substances. Two species of Corallococcus have been described previously (Corallococcus coralloides and Corallococcus exiguus)

Discovery of broadly-neutralizing antibodies against brown recluse spider and Gadim scorpion sphingomyelinases using consensus toxins as antigens. [PDF]

Protein Sci
Abstract Broadly‐neutralizing monoclonal antibodies are becoming increasingly important tools for treating infectious diseases and animal envenomings. However, designing and developing broadly‐neutralizing antibodies can be cumbersome using traditional low‐throughput iterative protein engineering methods. Here, we present a new high‐throughput approach

Advances in the reconstruction of the spider tree of life: A roadmap for spider systematics and comparative studies

Cladistics, Volume 39, Issue 6, Page 479-532, December 2023., 2023
Abstract In the last decade and a half, advances in genetic sequencing technologies have revolutionized systematics, transforming the field from studying morphological characters or a few genetic markers, to genomic datasets in the phylogenomic era. A plethora of molecular phylogenetic studies on many taxonomic groups have come about, converging on, or

Sexual selection and predation drive the repeated evolution of stridulation in Heteroptera and other arthropods

Biological Reviews, Volume 98, Issue 3, Page 942-981, June 2023., 2023
ABSTRACT Acoustic and substrate‐borne vibrations are among the most widely used signalling modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs generating acoustic sound and/or substrate‐borne vibrations, and are fundamental to our broader understanding of the evolution of animal signalling.

Increasing species richness along elevational gradients is associated with niche packing in bat assemblages

Journal of Animal Ecology, Volume 92, Issue 4, Page 863-874, April 2023., 2023
The link between increasing species richness and species' interactions in assemblages is known in plants and birds but rarely in mammals. This study is the first such on bat assemblages in an elevational gradient. Using stable isotopes, we show that niches get packed in assemblages with high species richness at low elevations, whereas, high elevation ...

Lizard predation by spiders: A review from the Neotropical and Andean regions

Ecology and Evolution, Volume 10, Issue 20, Page 10953-10964, October 2020., 2020
In this study, we analyze for the first time the lizard consumption by spiders in the Neotropical and Andean regions, showing that the families Ctenidae and Theraphosidae may be relevant lizard predators in these areas. In addition, we provide the first report on spider predation upon a vertebrate taxon in the Andean region.

Reciprocal transplantation of the heterotrophic coral Tubastraea coccinea (Scleractinia: Dendrophylliidae) between distinct habitats did not alter its venom toxin composition

Ecology and Evolution, Volume 10, Issue 4, Page 1794-1803, February 2020., 2020
Toxin complexity in the alien coral Tubastraea coccinea is conserved and co‐evolved with innovation of the venom delivery system. Morphological development of the coral and phenotypic expression of the venom and delivery system is not modulated by habitat pressures over short periods of time.
