Cupiennius spiders (Trechaleidae) from southern Mexico: DNA barcoding, venomics, and biological effect

Background: Members of the genus Cupiennius Simon, 1891 are categorized as wandering spiders and are part of the family Trechaleidae. The genomics and proteomics of Cupiennius spiders from North America remain uncharacterized. The present study explores for the first time molecular data from the endemic...

Minimalist revision of Mesochorus Gravenhorst, 1829 (Hymenoptera: Ichneumonidae: Mesochorinae) from Área de Conservación Guanacaste, Costa Rica, with 158 new species and host records for 129 species

Rev. biol. trop; 71 (), 2023
Introduction: Species of Mesochorus are found worldwide and members of this genus are primarily hyperparasitoids of Ichneumonoidea and Tachinidae. Objectives: To describe species of Costa Rican Mesochorus reared from caterpillars and to a lesser extent Malaise-trapped. Methods: The species are diagnosed ...

Biologia, ecologia e taxonomia molecular de Mansonia (Mansonia) Blanchard, 1901 (Diptera: Culicidae)

Introdução - As fêmeas do gênero Mansonia Blanchard, 1901 depositam seus ovos na face inferior das folhas de plantas aquáticas presentes em coleções de água doce. Após a eclosão, as larvas e, depois, as pupas se mantêm fixadas aos tecidos submersos das plantas. Assim que emergem, as fêmeas ad...

Taxonomía de los hongos: un rompecabezas al que le faltan muchas piezas

Biomédica (Bogotá); 43 (Supl. 1), 2023
Los hongos son organismos polifacéticos presentes en casi todos los ecosistemas de la tierra, donde establecen diversos tipos de simbiosis con otros seres vivos. A pesar de ser reconocidos por los humanos desde la antigüedad -y de la cantidad de trabajos que han profundizado sobre su biología y ecolog...

Review of the armoured catfish genus Hypostomus (Siluriformes: Loricariidae) from the Parnaíba River basin, Northeastern Brazil, with description of a new species

Neotrop. ichthyol; 20 (1), 2022
The species of Hypostomus from the Parnaíba River basin were reviewed through molecular and morphological analysis. Five species were found in the basin, including a new species herein described. The distribution of H. pusarum was expanded to this basin, and a closely related species was recorded (H. af...

DNA Barcoding unveils cryptic lineages of Hoplias malabaricus from Northeastern Brazil

Braz. j. biol; 81 (4), 2021
Abstract The trahira or wolf fish - Hoplias malabaricus- is a valid species, although recent cytogenetic and molecular studies have indicated the existence of a species complex. In this context, the present study analyzed the mitochondrial COI marker to determine the levels of genetic diversity of specim...

DNA barcoding revels first records of three rare coleopteran genera in Northern lakes of Egypt

Braz. j. biol; 81 (4), 2021
Abstract One aquatic coleopteran species from family Dytiscidae and two aquatic coleopteran genera from family Hydrophilidae were recorded in the summer period and represent first records in the Egyptian lakes. Beetles were collected from two northern lakes, Lake Idku and Lake Burullus. They were identif...

CO1-Based DNA barcoding for assessing diversity of Pteropus giganteus from the state of Azad Jammu Kashmir, Pakistan

Braz. j. biol; 81 (3), 2021
Abstract The flying fox (Pteropus giganteus) also familiar with the name of the greater Indian fruit Bat belongs to the order Chiroptera and family Pteropodidae. Current research emphasis on the DNA barcoding of P. giganteus in Azad Jammu Kashmir. Bat sequences were amplified and PCR products were sequen...

Análise molecular revela alta diversidade no complexo de espécies Hoplias malabaricus (Characiformes, Erythrinidae) de diferentes localidades amazônicas
Molecular analysis reveals high diversity in the Hoplias malabaricus (Characiformes, Erythrinidae) species complex from different Amazonian localities

Acta amaz; 51 (2), 2021
O DNA barcoding propõe que um fragmento de DNA possa servir para identificar espécies. Em peixes, um fragmento do gene COI tem se mostrado eficaz em muitos estudos com focos diferentes. Nós usamos essa ferramenta molecular para fornecer novas informações sobre a diversidade críptica encontrada no...

Patterns of ichthyofaunal diversity and distribution across Jebba Hydro-Electric Power (HEP) dam, Jebba, north-central Nigeria

Braz. j. biol; 81 (2), 2021
The ichthyofauna diversity of the Jebba Hydroelectric Power (HEP) Dam, Jebba, North-central Nigeria was studied. Fishes were sampled for 24 months using gill net, hook and line, and cast net. Individuals were identified using morphological and molecular (mitochondrial Cytochrome c Oxidase subunit I) data...
