Abstract:
... The acute toxicity of the aqueous and ethanol extracts of Parkia biglobosa pods against Clarias gariepinus was investigated under laboratory conditions. Agitated behaviours and respiratory distress were also observed during the exposure period. The adverse effects on biochemical parameters were assessed using semi-static bioassays for 28 days. The ethanol extract of P. biglobosa pods was found to ...

Subject:
Russia; empirical research; models
Abstract:
... The Exact Affine Stone Index (EASI) demand model offers distinct advantages over its predecessors. However, it does not account for pre-committed demand. This can bias elasticity estimates when such pre-commitments are present. We derive a generalized EASI model that allows for pre-committed demand. We illustrate the advantage of this model in an empirical analysis of food demand in Russia using p ...

Abstract:
... The results of ecological interactions depend on the costs and benefits involved in different ecological contexts. Turnera subulata is a shrubby plant with extrafloral nectaries that are associated with ants. Here, we test the hypotheses that the association between T. subulata and ants results in: (i) positive effects on host plant growth and reproduction; (ii) plant herbivory reduction and (iii) ...

Abstract:
... Four species of leaf beetles, Diorhabda spp, (Chrysomelidae), were introduced for biological control of saltcedar, Tamarix spp., an invasive small tree or shrub, in the US. In Texas, three species established at some sites but failed to establish or initially established but did not persist at other sites. Diorhabda larvae pupate in leaf litter on the soil surface and thus are exposed to ants and ...

We use observed patterns of species richness and composition of ant communities along a 1000 mm rainfall gradient in northern Australian savanna to assess the accuracy of species richness and turnover predictions derived from stacked species distribution models (S‐SDMs) and constrained by macroecological models (MEMs). We systematically sampled ants at 15 sites at 50 km intervals along the rainfal ...

These phytochemical responses to herbivore damage can affect herbivore performance and activity. Comprehensive studies on the ecological consequences of multi‐herbivore plant interactions are key to understanding plant–herbivore community dynamics. 2. This study examined how feeding damage by co‐occ ...

Abstract:
... DNA methylation is an important epigenetic modification that governs transcriptional regulation. The methylation mark is read by a special class of proteins called methyl-CpG-binding domain proteins. The role of DNA methylation has been found in X-chromosome inactivation, genomic imprinting, transposon silencing, and self-incompatibility. Recently, remodeling of global DNA methylation was demonstr ...

Our framework allows us to quantify the monetary value of individual rather than fixed sets of attributes. Results indicate that young producers are most likely to join an alliance, and high participation fees are a signific ...

Abstract:
... Grain amaranth, Amaranthus L., is an emerging crop cultivated worldwide. One way in which resources from the amaranth crop could be exploited as an alternative to grain is to grow amaranth in the dry season, harvest only the leaves, and incorporate them into meals. In this environmental condition, insects associated with the amaranth crop are poorly known. Results showed that Diabrotica balteata L ...

Few studies model factors that influence CWD availability, although such investigations are critically needed to inform sustainable forest management. We assess benchmark levels of CWD in unharvested native forests and those harvested for timber, across a range of forests in north‐east New South Wales, Australia. We ...
