The costs of extra‐pair behaviours in birds
Biological Reviews, EarlyView.ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Monogamy and high relatedness do not preferentially favor the evolution of cooperation
BMC Evolutionary Biology, 2011 Background Phylogenetic analyses strongly associate nonsocial ancestors of cooperatively-breeding or eusocial species with monogamy. Because monogamy creates high-relatedness family groups, kin selection has been concluded to drive the evolution of ...

Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Landscape structure and population density affect intraspecific aggression in beavers
Ecology and Evolution, 2020 Intraspecific competition plays an important role for territory acquisition and occupancy, in turn affecting individual fitness. Thus, understanding the drivers of intraspecific aggression can increase our understanding of population dynamics.

Occupational HPV Exposure in Otolaryngology: A Scoping Review of Detection, Risk, and Prevention
The Laryngoscope, EarlyView.This scoping review identified 10 studies evaluating occupational HPV exposure in otolaryngology. HPV DNA was detected in surgical plume following some HPV‐related procedures, including up to 56.7% of CO2 laser plume samples, while the only study assessing oral HPV among exposed clinicians reported a prevalence of 2.2%, not exceeding that of the ...

What Program for Love in the 21st Century? Thinking With and Beyond Luhmann
Systems Research and Behavioral Science, EarlyView.ABSTRACT From a sociological perspective, the paper examines how normative frameworks for intimate relationships have changed since the publication of Luhmann's Love as Passion (1982). Building on Luhmann's notion of a program for love, we discuss his claim that late 20th century love semantics were organized around a program of understanding. We argue

, 2015 Abstract Monogamy is ethnographically peculiar as an ethical ideal and emerged in the Early Middle Ages as a form of sexual repression imposed by the Church and employed by secular authorities to decompose powerful elite lineages. In its continued modern form, the independent and isolated monogamous household has been advanced as socially optimal by ...
