Developmental plasticity of thermal performance curve for reproduction in Drosophila melanogaster.

In ectotherms, body temperature is a crucial determinant of performance and fitness, as captured by thermal performance curves (TPCs). Since survival in variable environments is often facilitated by phenotypic plasticity, to reliably assess an organism's ability to cope with thermal changes, it is necessary to characterize not only TPCs but also their reaction norms. While previous studies have investigated plasticity in TPCs, these studies focus only on selected parameters and a few developmental temperatures.

Neotropical Melyroidea group cockroaches reveal various degrees of (eu)sociality.

Eusociality in its various degrees represents an animal social system characterised by cooperative brood care, differentiation into castes and generational overlap. The fossil record indicates that eusociality is likely to have originated in hymenopterans and blattodeans during the Cretaceous. In this study, we present findings from surveys in Peruvian (Villa Carmen) and Ecuadorian (Rio Bigal, El Reventador) cloud forests revealing the first extant cockroach species living in complex, structured groups (n = 90-200 individuals, ˃ 20 adults).

New genus and species of cockroaches from the tribe Brachycolini (Blattaria: Blaberidae: Blaberinae) and redescription of the Hormetica strumosa.

From the tribe Brachycolini Beier, 1961 new genus with one species Quadrihormetica onorei Vidlička, gen. et sp. n.

New genus and species of cavernicolous cockroach (Blattaria, Nocticolidae) from Vietnam.

The new, small cavernicolous species Helmablatta louisrothi gen. et sp. n.

Origin of origami cockroach reveals long-lasting (11 Ma) phenotype instability following viviparity.

Viviparity evolved in bacteria, plants, ˃141 vertebrate lineages (ichthyosaurs, lizards, fishes, mammals, and others), and in 11 of 44 insect orders. Live-birth cockroaches preserved with brood sac (3D recovered two times optically) included Diploptera vladimir, Diploptera savba, Diploptera gemini spp.n.

New cockroach species of the genus Panchlora Burmeister (Blaberidae, Panchlorinae) from Ecuador.

The genus Panchlora includes 49 species, but only 45 are widely distributed in Central and South America. Most of them are green. The new species herein described presents an ornamental coloration markedly different of all until now described species.

Description of Helicoconis tatricus sp. n. (Neuroptera, Coniopterygidae) from Slovakia (Central Europe) and key for determination of all Palaearctic species of subgenus Helicoconis.

A new species of dustywings, Helicoconis tatricus sp. n., is described from the foothills of the Tatra Mountains in Slovakia.

Cockroaches probably cleaned up after dinosaurs.

Dinosaurs undoubtedly produced huge quantities of excrements. But who cleaned up after them? Dung beetles and flies with rapid development were rare during most of the Mesozoic. Candidates for these duties are extinct cockroaches (Blattulidae), whose temporal range is associated with herbivorous dinosaurs.

New species of Macrophyllodromia (Blattaria, Blattellidae) from Ecuador and a key to males of the genus.

Representatives of the cockroach genus Macrophyllodromia are widely distributed in Central and South Americas. The genus involves 10 species, including one new species described here, that are divided into 3 species groups--splendida, amabile and maximiliani. Macrophyllodromia onorei sp.

Paleocene origin of the cockroach families Blaberidae and Corydiidae: Evidence from Amur River region of Russia.

Morphna paleo sp. n., the earliest winged representative of any living cockroach genus and the earliest representative of the family Blaberidae, is described from the Danian Arkhara-Boguchan coal mine in the Amur River region (Russian Far East).

Cockroaches (Blattaria) of Ecuador-checklist and history of research.

Cockroaches are an understudied group and the total number of described taxa increases every year. The last checklist of Ecuador species was published in 1926. The main aim of this study was to complete a new checklist of cockroach species recorded in Ecuador supplemented with a research history of cockroaches (Blattaria) on the territory of continental Ecuador.
