The rainbow lorikeet has often included the red-collared lorikeet (T. rubritorquis) as a subspecies, but today most major authorities consider it separate. [14] [15] Additionally, a review in 1997 led to the recommendation of splitting off some of the most distinctive taxa from the Lesser Sundas as separate species, these being the scarlet-breasted lorikeet (T. forsteni), the marigold lorikeet ...
Sociobiology investigates social behaviors such as mating patterns, territorial fights, pack hunting, and the hive society of social insects. It argues that just as selection pressure led to animals evolving useful ways of interacting with the natural environment, so also it led to the genetic evolution of advantageous social behavior. [4]
The behavioural synchrony model universe relies on two key sets of assumptions. The first set of assumptions concerns the structure of the network: it is assumed that (a) the agents form a social network in a way that the network is connected, i.e., all agents have some direct or indirect connection to every other agent, and sparse, i.e., the network the agents form is not fully connected; and ...
For example, in paper wasp species, Agelaia pallipes, social facilitation is used to recruitment to food resources. By using chemical communication, A. pallipes pool the independent search efforts to locate and defend food sources from other organisms. [19] Social facilitation is sometimes used to develop successful social scavenging strategies.
Sociobiology: The New Synthesis (1975; 25th anniversary edition 2000) is a book by the biologist E. O. Wilson.It helped start the sociobiology debate, one of the great scientific controversies in biology of the 20th century and part of the wider debate about evolutionary psychology and the modern synthesis of evolutionary biology.
Tinbergen's four questions, named after 20th century biologist Nikolaas Tinbergen, are complementary categories of explanations for animal behaviour. These are also commonly referred to as levels of analysis. [1] It suggests that an integrative understanding of behaviour must include ultimate (evolutionary) explanations, in particular:
Loriinae is a subfamily of psittacine birds, one of the six subfamilies that make up the family Psittaculidae.It consists of three tribes, the lories and lorikeets (), the budgerigar (Melopsittacini) and the fig parrots (Cyclopsittini), which are small birds, mostly of bright colors and inhabitants of Oceania and the islands of Southeast Asia.
Changes in an individual's social network environment can also influence characteristics such as 'personality': for example, social spiders that huddle with bolder neighbors tend to increase also in boldness. [47] This is a very small set of broad examples of how researchers can use network analysis to study animal behavior.
