The evolution of ageing in cooperative breeders

open access: yesEvolution Letters, 2022
Cooperatively breeding animals live longer than their solitary counterparts. This has been suggested for birds, mole rats, and social insects. A common explanation for these long lifespans is that cooperative breeding evolves more readily in long‐lived ...

Cooperative breeding and long-distance dispersal: a test using vagrant records. [PDF]

open access: yesPLoS ONE, 2013
Cooperative breeding is generally associated with increased philopatry and sedentariness, presumably because short-distance dispersal facilitates the maintenance of kin groups.

Genomic Features of Cladobotryum dendroides, Which Causes Cobweb Disease in Edible Mushrooms, and Identification of Genes Related to Pathogenicity and Mycoparasitism

open access: yesPathogens, 2020
Cladobotryum dendroides, which causes cobweb disease in edible mushrooms, is one of the major fungal pathogens. Our previous studies focused on the genetic and morphological characterization of this fungus, as well as its pathogenicity and the ...

Genomic Breeding Programs Realize Larger Benefits by Cooperation in the Presence of Genotype × Environment Interaction Than Conventional Breeding Programs

open access: yesFrontiers in Genetics, 2020
Genotype × environment interaction (G × E) is of increasing importance for dairy cattle breeders due to international multiple-environment selection of animals as well as the differentiation of production environments within countries.

Synopsis of Leptosphaeriaceae and Introduction of Three New Taxa and One New Record from China

open access: yesJournal of Fungi, 2022
Leptosphaeriaceae, a diverse family in the order Pleosporales, is remarkable for its scleroplectenchymatous or plectenchymatous peridium cells. Four Leptosphaeriaceae species were discovered and studied during the investigation of saprobic fungi from ...

Dispersal costs set the scene for helping in an atypical avian cooperative breeder [PDF]

open access: yes, 2001
The ecological constraints hypothesis is suggested to explain the evolution of cooperative breeding in birds. This hypothesis predicts that the scene for cooperative breeding is set when ecological factors constrain offspring from dispersal.

Cortisol levels are positively associated with pup-feeding rates in male meerkats [PDF]

open access: yes, 1980
In societies of cooperative vertebrates, individual differences in contributions to offspring care are commonly substantial. Recent attempts to explain the causes of this variation have focused on correlations between contributions to care and the ...

Experimental evidence for kin-biased helping in a cooperatively breeding vertebrate [PDF]

open access: yes, 2001
The widespread belief that kin selection is necessary for the evolution of cooperative breeding in vertebrates has recently been questioned. These doubts have primarily arisen because of the paucity of unequivocal evidence for kin preferences in ...

Cooperation theory of cooperative breeding [PDF]

open access: yesBehavioural Processes, 2007
Cooperative breeding is the joint raising of offspring by wo or more individuals, where at least one of them is not he genetic parent of the young. The key characteristics of ooperative breeding systems are diversity of social behaviours ithin and between groups and high variation of factors influncing conflict over reproduction (for review see Komdeur,

Integrating cooperative breeding into theoretical concepts of cooperation [PDF]

open access: yesBehavioural Processes, 2007
In cooperative breeding systems, some individuals help to raise offspring that are not their own. While early explanations for such altruistic behaviour were predominantly based on kin selection, recent evidence suggests that direct benefits may be important in the maintenance of cooperation.
