Scepticism in CSR Advertisements
The aim of the present paper is to make a contribution to CSR communication theory by investigating the level of substantial information provided in CSR print advertisements in the UK and Brazil. The paper evaluates CSR advertisements using textual analysis.The empirical evidence demonstrates that companies provide a low level of substantial information when advertising CSR.The paper provides empirical evidence as to the extent that corporations use substantial information in their advertisements
[i]Conidames[/i], a new oriental genus of Sycophaginae (Hymenoptera, Agaonidae) associated with [i]Ficus[/i] section Conosycea (Moraceae)
The sycophagines are strictly associated with two subgenera of Fit to L. (Moraceae), namely,Slycomo77/S and Urostignza. They mostly oviposit through the fig wall and lay their eggs within the fig flowers, being either gall-makers or parasitoids of other fig wasps. In this contribution, a new genus of Sycophaginae, [i]Conidarnes[/i] Earache & Rasplus, gen. n., is described with seven new species: [i]Conidarnes achterbergi[/i] Earache & Rasplus, sp. n.; [i]Conidarwes beryl'[/i] Farache & Rasplus, sp. n.; [i]Conidarnes laevis[/i] Earache & Rasplus, sp. n.;[i] Conidames santineloi[/i] Earache & Rasplus, sp. n.; [i]Conidarnes subtectae[/i] Earache & Rasplus, sp. n.; [i]Conidarnes sidcata[/i] Farache & Rasplus, sp. n.; and [i]Conidarnes sumatranae[/i] Farache & Rasplus, sp. n. Illustrations, morphological diagnoses, dichotomous keys and multi-entry online keys to species are provided. [i]Conidarnes[/i] species strictly occur in the oriental region, and their distribution does not oVerlap with the distribution of the two other genera belonging to the same clade. Due to their relative rarity, we encourage extensive sampling of Conosycea figs to improve our knowledge of the genus
First record of a non-pollinating fig wasp (Hymenoptera: Sycophaginae) from Dominican amber, with estimation of the size of its host figs
Fig trees and their pollinating fig wasps arose about 75 million years ago in the Cretaceous period. Several other groups of chalcid wasps also utilize figs for larval development, including sycophagines, the putative sister group to pollinating fig wasps. Whereas stone and amber fossil pollinators are known, no fossils representing non-pollinating fig wasp groups have been confirmed previously. Here, we describe the first Sycophaginae from the c.15–20 Ma Dominican amber, Idarnes thanatos sp. nov. Farache, Rasplus, Pereira and Compton, and discuss its relationships within the Idarnes carme species group. Additionally, we use linear regression to compare body size, ovipositor sheaths length, and host fig size data from extant Idarnes species to estimate the size of its host figs. Idarnes thanatos was most likely associated with small to medium sized figs (diameter ≤1.0 cm), that were likely to have been dispersed by birds and primates. The discovery of this close relative of extant non-pollinating fig wasps suggests that early Miocene and modern fig wasp communities may share similar ecological and functional features
