Key to species

Two small genera of the subfamily Braconinae, Angustibracon Quicke, 1987 and Pseudospinaria Enderlein, 1905, are reported for the first time from Vietnam. Two Angustibracon species, Angustibracon leptogaster Cameron and Angustibracon maculiabdominis Zhou & You and one Pseudospinaria species, Pseudospinaria attenuata (Westwood) are newly recorded for Vietnam’s braconid fauna. Additionally, the species are redescribed and illustrated. An illustrated key to the two known Augustibracon species and a mapped distribution of species in Vietnam are also given.

The identification of most species relied on careful examination of their morphological characters. These findings collectively raised the Ophichthus genus’s representation in Vietnamese waters by introducing three previously undocumented species, raising the total count to 17 compared to prior research. Furthermore, this study provides a comprehensive key to aid in identifying the various Ophichthus species found in Vietnam.

This study compares the effectiveness of a digital and a paper-based dichotomous identification key for teaching pre-service teachers about plant species diversity. Twenty-four Slovenian teachers in pre-service training used a digital version of the key on tablet computers and twenty-nine used a paper-based version to identify woody species in the garden near their university faculty.

Ebook "Studying vibrational communication (Animal signals and communication, Volume 3)" explains the key ideas, questions and methods involved in studying the hidden world of vibrational communication in animals. The authors dispel the notion that this form of communication is difficult to study and show how vibrational signaling is a key to social interactions in species that live in contact with a substrate, whether it be a grassy lawn, a rippling stream or a tropical forest canopy. This ancient and widespread form of social exchange is also remarkably understudied.

In ebook "High- and low-valent tris-N-heterocyclic carbene iron complexes: A study of molecular and electronic structure" high valent iron nitride and oxo species have been proposed as key intermediates in many bio-catalytic transformations, but until now these species have proven exceedingly challenging to isolate and study. Iron complexes in high oxidation states can thus serve as models for iron-containing enzymes to help us understand biological systems or aid our development of more efficient industrial catalysts.

Ebook "Encyclopedia of South American aquatic insects: Odonata - Zygoptera - Illustrated keys to known families, genera, and species in South America" was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in some cases, to include terrestrial species of orders that include both terrestrial and aquatic taxa.
