Hierarchical networks of food exchange in the black garden ant Lasius niger
2020
In most eusocial insects, the division of labour results in relatively few individuals foraging for the entire colony. Thus, the survival of the colony depends on its efficiency in meeting the nutritional needs of all its members. Here, we characterise the network topology of a eusocial insect to understand the role and centrality of each caste in this network during the process of food dissemination. We constructed trophallaxis networks from 34 food-exchange experiments in black garden ants (Lasius niger). We tested the influence of brood and colony size on (i) global indices at the network level (i.e. efficiency, resilience, centralisation and modularity) and (ii) individual values (i.e. …
Trends in scientific research on climate change in agriculture and forestry subject areas (2005–2014)
2017
The term “Climate change” involves an alteration of the mean and variability of the climate properties. It implies unusual variations in the planet earth atmosphere, which causes related effect on other parts of the planet. The reduction in the land crops annual yield is derived from those alterations. The objective of this paper was to contribute to a better understanding of the scientific knowledge of climate change and its effect concerning agriculture and investigate its evolution through published papers. The items under study were obtained from the Web of Science (WOS) platform from Thomson Reuters. A bibliometric and social network analysis was performed to determine the indicators o…

Interlocking directorates in sports organization network Focus in this article is on interlocking directorates in sports organization network. The aim is to study the networks ́ structure and how it has changed during the time period 1993–2014. The data consists of central organizations boards and states sport policy working groups (n=121). The data have been analysed in Ucinet-network program. Results indicates that power-elite have come narrow year by year, but there ́s seven organization which have been in central position in every decade. The conclusion is, that in the sports organization network, there have been at the same both momentariness and perfusion, but the power-elite have bee…
