Description of a new Psalmopoeus Pocock, 1895 species (Araneae, Theraphosidae, Psalmopoeinae) from the Chocó region of Ecuador.

A new species of Theraphosidae, genus Psalmopoeus Pocock, 1895 is described from the Chocó region of Ecuador, Psalmopoeus pristirana n. sp. (male and female).

Seven new species of the enigmatic spider genus Paratropis Simon, 1889 (Mygalomorphae, Paratropididae) from Ecuador.

Seven new species of the enigmatic spider family Paratropididae are described from Ecuador. All new species belong to the genus Paratropis: P. carcosita sp.

Alkaloids are associated with increased microbial diversity and metabolic function in poison frogs.

Shifts in host-associated microbiomes can impact both host and microbes. It is of interest to understand how perturbations, like the introduction of exogenous chemicals, impact microbiomes. In poison frogs (family Dendrobatidae), the skin microbiome is exposed to alkaloids that the frogs sequester for defense.

Reduced fertilization supplemented with RGM 2450 and RGM 2529 promotes tomato production in a sustainable way.

The rising demand for vegetables has driven the adoption of greenhouse cultivation to guarantee high yields and quality of fresh produce year-round. Consequently, this elevates the demand for fertilizers, whose costs are progressively escalating. RGM 2450 and RGM 2529 are plant growth-promoting rhizobacteria (PGPR).

Path for recovery: an ecological overview of the Jambato Harlequin Toad (Bufonidae: ) in its last known locality, Angamarca Valley, Ecuador.

The Jambato Harlequin toad (), a formerly abundant species in the Andes of Ecuador, faced a dramatic population decline in the 1980s, with its last recorded sighting in 1988. The species was considered Extinct by the IUCN until 2016, when a fortuitous discovery of one Jambato by a local boy reignited hope. In this study, we present findings from an investigation conducted in the Angamarca parish, focusing on distribution, abundance, habitat preferences, ecology, disease susceptibility, and dietary habits of the species.
