An organism's gut microbiome handles most of the metabolic processes associated with food intake and digestion but can also strongly affect health behavior. A stable microbial core community in provides general competences for substrate degradation is robust against extrinsic disturbances like changing diets or pathogens. Black Soldier Fly larvae (BSFL; Hermetia illucens) are well known their ability to efficiently degrade a wide spectrum organic materials. The ingested substrates build up...
Canteens represent an essential food supply hub for educational institutions, companies, and business parks. Many people in these locations rely on a guaranteed service with consistent quality. It is ongoing challenge to satisfy the demand sufficient serving numbers, portion sizes, menu variations cover intolerances different palates of customers. However, overestimating this or fluctuating quality dishes leads inevitable loss unconsumed due leftovers. In study, waste fraction canteen...
ABSTRACT Spatial modelling of species distributions has become an important tool in the study biological invasions. Here, we examine utility combining distribution and ecological niche for retrieving information on invasion processes, based occurrence data from native introduced ranges. Specifically, discuss questions, concerning (1) global potential to spread other ranges, (2) within established invasions, (3) detectability differences across (4) ability infer history through range. We...
It is unclear why some species become successful invaders whilst others fail, and whether invasive success depends on pre-adaptations already present in the native range or characters evolving de-novo after introduction. Ants are among worst pests, with Lasius neglectus its rapid spread through Europe Asia as most recent example of a pest ant that may global problem. Here, we first integrated study behavior, morphology, population genetics, chemical recognition parasite load L. non-invasive...
The widespread occurrence of Wolbachia in arthropods and nematodes suggests that this intracellular, maternally inherited endosymbiont has the ability to cross species boundaries. However, direct evidence for such a horizontal transmission nature is scarce. Here, we compare well-characterized infection European cherry fruit fly, Rhagoletis cerasi, with North American eastern cingulata, recently introduced Europe. Molecular genetic analysis based on multilocus sequence typing surface protein...
Abstract Wolbachia is a maternally inherited and ubiquitous endosymbiont of insects. It can hijack host reproduction by manipulations such as cytoplasmic incompatibility ( CI ) to enhance vertical transmission. Horizontal transmission also result in the colonization new mitochondrial lineages. In this study, we present 15‐year‐long survey cherry fruit fly Rhagoletis cerasi across Europe spatiotemporal distribution two prevalent strains, w Cer1 Cer2, associated haplotypes Germany. Across most...
Abstract The European steppes and their biota have been hypothesized to be either young remnants of the Pleistocene steppe belt or, alternatively, represent relicts long-term persisting populations; both scenarios directly bear on nature conservation priorities. Here, we evaluate value threatened disjunct steppic grassland habitats in Europe context Eurasian biome. We use genomic data ecological niche modelling assess pre-defined, biome-specific criteria for three plant arthropod species....
Hermetia illucens (L.), the Black Soldier Fly, has received increased scientific attention for its potential in circular waste management where larvae can serve as feedstuff livestock and biodiesel production. The flies occur naturally (sub)-tropical warm-temperate climates, their mating depends on space sunlight. Small-scale indoor rearing of Flies been challenging because they react sensitive to artificial light sources cage sizes, but recent studies have shown that small-scale under is...
Accurate species delimitation is fundamental to biology. Traditionally, were delimited based on morphological characters, sometimes leading taxonomic uncertainty in morphologically conserved taxa. Recently, multiple taxonomically challenging cases have benefited from integrative taxonomy-an approach that highlights congruence among different disciplines and invokes evolutionary explanations for incongruence, acknowledging methods can mirror stages of the speciation continuum. Here, we used a...
The range of hosts exploited by a parasite is determined several factors, including host availability, infectivity and exploitability. Each these can be the target natural selection on both parasite, which will determine local outcome interactions, potentially lead to coevolution. However, geographical variation in use specificity has rarely been investigated. Maculinea (= Phengaris ) butterflies are brood parasites Myrmica ants that patchily distributed across Palæarctic have studied...
Quaternary climatic oscillations had a large impact on European biogeography. Alternation of cold and warm stages caused recurrent glaciations, massive vegetation shifts, large-scale range alterations in many species. The Eurasian steppe biome its grasslands are noteworthy example; they underwent climate-driven, contractions during expansions stages. Here, we evaluate the these late demography several phylogenetically distant plant insect species, typical steppes. We compare three explicit...
Mutualism, whereby species interact to their mutual benefit, is extraordinary in a competitive world. To recognize general patterns of origin and maintenance from the plethora mutualistic associations proves persisting challenge. The simplest situation believed be that single mutualist specific host, vertically transmitted one host generation next. We characterized ascomycete fungal associates cultured for nest architecture by ant subgenera Dendrolasius Chthonolasius . ants probably manage...
Litter decomposition patterns, non-additive effects, and spectral data of abundant alpine leaf litters were assessed in litterbag experiments containing single species mixtures. We tested if low-quality shrub litter decomposes faster mixtures with high-quality predictions on decomposed using are feasible. Chemical physical traits near-infrared reflectance (NIR) spectra six freshly fallen types measured. A experiment (0.1 mm mesh size) 2- 3-species was conducted three from functional groups...
The Pleistocene climatic fluctuations had a huge impact on all life forms, and various hypotheses regarding the survival of organisms during glacial periods have been postulated. In European Alps, evidence has found in support refugia outside ice shield (massifs de refuge) acting as sources for postglacial recolonization inner-Alpine areas. contrast, nunataks, ice-free areas above glacier, remains scarce. Here, we combine multivariate genetic analyses with ecological niche models (ENMs)...
