Millipedes are organisms of the edaphic fauna and have been used as bioindicators for the evaluation of pollutants in the environment, as they are in constant contact with the soil. This study used the millipede Rhinocricus ... -
Ergatoid reproductives in the Neotropical termite Nasutitermes aquilinus (Holmgren) (Blattaria: Isoptera: Termitidae): developmental origin, fecundity, and genetics
da Silva, Iago Bueno; ; ; ; ; ; Costa-Leonardo, Ana Maria (Insect Science, 2019) [Artigo]
Termite colonies are usually headed by primary reproductives, which establish nests during the swarming season. However, secondary reproductives may develop in some species and become supplementary or replacement breeders, ... -

da Silva, Luiza Helena Bueno; ; Costa-Leonardo, Ana Maria (Zoology, 2019) [Artigo]
Social insects display a range of sophisticated behaviors to deal with cadavers, which together act to guarantee the health and social homeostasis of their colonies. In termites, cadaver management involves an entire ... -
Geographic distributions of Pseudopaludicola boliviana and congeneric long-legged species (Anura: Leiuperinae)
; ; Lyra, Mariana Lúcio; Gazoni, Thiago ; ; Haddad, Célio Fernando Baptista ; ; (Studies on Neotropical Fauna and Environment, 2020) [Artigo]
In recent years, the taxonomic knowledge of Pseudopaludicola has increased and it is currently possible to elucidate aspects of the species within this genus such as their geographic distributions. Here we accessed new ... -

Revealing the Venomous Secrets of the Spider's Web
Esteves, Franciele Grego; Dos Santos-Pinto, José Roberto Aparecido ; Ferro, Milene ; ; ; ; ; ; ; Bacci Júnior, Mauricio et al. (Journal of Proteome Research, 2020) [Artigo]
Orb-weaving spiders use a highly strong, sticky and elastic web to catch their prey. These web properties alone would be enough for the entrapment of prey; however, these spiders may be hiding venomous secrets in the web, ... -
Using a toxicoproteomic approach to investigate the effects of thiamethoxam into the brain of Apis mellifera
