The factors determining gradients of biodiversity are a fundamental yet unresolved topic in ecology. While diversity have been analysed for numerous single taxa, progress towards general explanatory models has hampered by limitations the phylogenetic coverage past studies. By parallel sampling 25 major plant and animal taxa along 3.7 km elevational gradient on Mt. Kilimanjaro, we quantify cross-taxon consensus evaluate predictors from to multi-taxa community level. show complex distribution...
Despite sequestration of toxins being a common coevolutionary response to plant defence in phytophagous insects, the macroevolution traits involved is largely unaddressed. Using phylogenetic approach comprising species from four continents, we analysed ability sequester toxic cardenolides hemipteran subfamily Lygaeinae, which widely associated with cardenolide-producing Apocynaceae. In addition, cardenolide resistance their Na + /K -ATPases, molecular target cardenolides. Our data indicate...
AbstractHost plant specialization across herbivorous insects varies dramatically, but while the molecular mechanisms of host adaptations are increasingly known, we often lack a comprehensive understanding selective forces that favor specialization. The milkweed bugs (Heteroptera: Lygaeinae) ancestrally associated with plants Apocynaceae from which they commonly sequester cardiac glycosides for defense, facilitated by resistant Na+/K+-ATPases and transport, storage, discharge toxins. Here,...
The knowledge of insect biodiversity Botswana is far from perfect. By 2015, there were only inventories publicly available for butterflies, dragonflies and grasshoppers. Here we report 331 species subspecies true bugs (Heteroptera), which 242 records extracted scattered published literature online sources, 89 (27%) are new Botswana. These data significantly increase the number known by roughly 30%.
Ancient, long-extinct floras and faunas can be reassembled through fossils phylogenetics, even palaeo-environments reconstructed with the aid of palaeoclimatology. However, very little is known about sound-scape past. Of what kind were first biologically meaningful sounds vibrations ever emitted perceived? The earliest signals in history life probably produced by arthropods making use mechanical properties their exoskeleton. Here, we report an observation vibrational signalling...
Altered adult hippocampal neurogenesis (AN) plays a role in the etiopathology of Alzheimer's disease (AD), disorder characterized by progressive loss memory and spatial orientation impairment. Diabetes is shown to be one risk factor for development sporadic form AD (sAD), which affects >95% patients. Streptozotocin intracerebroventricularily (STZ icv) treated rats, develop an insulin-resistant brain state learning deficits preceding amyloid beta tau pathology, may act as appropriate animal...
Rats intracerebroventricularily (icv) treated with streptozotocin (STZ), shown to generate an insulin resistant brain state, were used as animal model for the sporadic form of Alzheimer's disease (sAD). Previously, we showed in vivo study that 3 months after STZ icv treatment hippocampal adult neurogenesis (AN) is impaired. In present study, examined effects on isolated neural stem cells (NSCs) using vitro approach. We revealed 2.5 mM inhibits proliferation NSCs indicated by reduced number...
Abstract The adaptation of herbivorous insects to new host plants is key their evolutionary success in diverse environments. Many are associated with mutualistic gut bacteria that contribute the host's nutrition and can thereby facilitate dietary switching polyphagous insects. However, how microbial communities differ between populations same species feed on different remains poorly understood. Most Pyrrhocoridae (Hemiptera: Heteroptera) specialist seed‐feeders family Malvaceae, although one...
The Oriental genus Leprota Melichar, 1912, is formally resurrected from synonymy with Saigona Matsumura, 1910, and re-established here as a valid genus. Its type species L. melichari Fennah, 1963, redescribed illustrated based on the newly designated lectotype, including first description of male genitalia. A new described northern Borneo, Malaysia.

The antispastic agent andN-methyl-D-aspartate (NMDA) receptor antagonist memantine has recently been proposed as a neuroprotective drug for use in patients with dementia syndromes primarily temporal lobe pathology, e.g. senile of Alzheimer type or Parkinson's disease. In quantitative autoradiographic study human post mortem hippocampus, was able to inhibit binding the noncompetitive NMDA-antagonist [3H]MK-801 ((+)-5-methyl-10,11-dihydro-5H-dibenzo(a,d)cyclohepten-5,10-imine maleate)...
On Lygaeus simulans spec. nov. and L. equestris (Linneaus, 1758), Two Closely Related Palearctic Lygaeinae (Heteroptera, Lygaeidae) The binomen applies to two distinct but related sympatric species, both of palearctic distribution. is described the differences between new species s. str. are discussed.
Abstract Host plant specialization across herbivorous insects varies dramatically, but the underlying evolutionary mechanisms are little-known. The milkweed bugs (Heteroptera: Lygaeinae) ancestrally associated with plants of Apocynaceae from which they commonly sequester cardiac glycosides for defense, facilitated by resistant Na + /K -ATPases and adaptations transport, storage discharge toxins. Here, we show that three Lygaeinae species independently colonized four novel non-apocynaceous...

The Oriental genus Protolepta Melichar is revised to include two species: P. turbata (the type species) and linnavuorii sp. nov., both from Sulawesi, Indonesia. Redescription provided for together with habitus photographs detailed illustrations of the male genitalia first time. A key species a distribution map are given.
On the Structure of Parameres, Phallus, and Genital Capsule Lygaeinae Systematic Notes on Subfamily (Heteroptera, Lygaeidae) Based a study representatives more than 40 genera subfamily Lygaeinae, parameres, phallus, genital capsule are described. The importance these characters for classification possible grouping within this discussed. Conflicting views concerning relationship mentioned. Several terms used by some other authors synonymized.
The species of Apterola MULSANT & REY genus is represented by the following species: kuenckeli Mulsant Rey (= rubicunda STÅL, gridellii MANCINI and pedestris STÅL), lownii SAUNDERS, 1876, iberica HORVATH, 1899, ramburi PELAEZ, 1942 pallida SLATER, 1964. variability in colour diverse characteristics these as well differences similarities with other are discussed. subspecies A.

The Neotropical planthopper genus Trigava O’Brien, 1999 (Hemiptera, Fulgoromorpha, Dictyopharidae, Nersiini) is revised. Four species are included: T. brachycephala (Melichar, 1912) (the type species, from Peru), obrieni Song, Malenovský & Deckert, sp. nov.

All described, including habitus photographs detailed illustrations of the male genitalia. Male female...
The purpose of this application, under Article 23.9.3 the Code, is to conserve widely used specific name Metochus abbreviatus Scott, 1874, for a species rhyparochromid bugs from East Asia. threatened by senior subjective synonym Rhyparochromus erosusWalker, 1872, which has seldom been since its first publication. Therefore, precedence 1874 over 1872 proposed.
