Comparative expression profiles of carboxylesterase orthologous CXE14 in two closely related tea geometrid species, Ectropis obliqua Prout and Ectropis grisescens Warren

open access: yesFrontiers in Physiology, 2023
Insect carboxylesterases (CXEs) can be expressed in multiple tissues and play crucial roles in detoxifying xenobiotic insecticides and degrading olfactory cues.

Geographic distribution of Pellia spp. (hepaticae, metzgeriales) in Poland based on electrophoretic identification

open access: yesActa Societatis Botanicorum Poloniae, 2014
Many species of liverworts (Hepaticae) are morphologically plastic to such an extent that their proper recognition may cause difficulties even for a specialist. Central European species of the genus Pellia are notorious in this respect.

Limnephilid taxa revised by speciation traits: Rhadicoleptus, Isogamus, Melampophylax genera, Chaetopteryx rugulosa, Psilopteryx psorosa species groups, Drusus bolivari, Annitella kosciuszkii species complexes (Trichoptera: Limnephilidae) [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2015
Speciation traits of paramere, paraproct and aedeagus were applied to find initial split criteria with fine structure analysis in order to prepare diverged trait matrices for delimiting phylogenetic incipient species of unsettled limnephilid taxa in the ...

Supplementary feeding increases nestling feather corticosterone early in the breeding season in house sparrows [PDF]

open access: yes, 2017
Several studies on birds have proposed that a lack of invertebrate prey in urbanized areas could be the main cause for generally lower levels of breeding success compared to rural habitats.

Investigating the potential sibling species status of Anopheles fluviatilis in Gadchiroli, Maharashtra, India

open access: yesJournal of Vector Borne Diseases
Background & objectives: India has made significant progress in combating malaria and reducing malaria-related mortality and morbidity. Yet, local transmission and malaria hotspots are important hurdles as India looks to achieve malaria elimination by ...

Variations in susceptibility to common insecticides and resistance mechanisms among morphologically identified sibling species of the malaria vector Anopheles subpictus in Sri Lanka

open access: yesParasites & Vectors, 2012
Background Anopheles subpictus s.l., an important malaria vector in Sri Lanka, is a complex of four morphologically identified sibling species A-D. Species A-D reportedly differ in bio-ecological traits that are important for vector control.

Which phylogenetic networks are merely trees with additional arcs? [PDF]

open access: yes, 2015
A binary phylogenetic network may or may not be obtainable from a tree by the addition of directed edges (arcs) between tree arcs. Here, we establish a precise and easily tested criterion (based on `2-SAT') that efficiently determines whether or not any ...

Ultraviolet plumage reflectance distinguishes sibling bird species [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
Realistic studies of plumage color need to consider that many birds can see near-UV light, which normal humans cannot perceive. Although previous investigations have revealed that UV-based plumage reflectance is an important component of various intraspecific social signals, the contribution of UV signals to inter-specific divergence and ...

Sympatric coexistence of sibling species Harmonia yedoensis and H. axyridis (Coleoptera: Coccinellidae) and the roles of maternal investment through egg and sibling cannibalism

open access: yesEuropean Journal of Entomology, 2008
The sibling species H. yedoensis Takizawa coexists sympatrically and simultaneously with H. axyridis only on pine trees in Japan. To elucidate the mechanisms enabling coexistence of these two sympatric sibling species, a laboratory experiment was ...
