Arthritis Care &Research, EarlyView.Objective The objective of this study was to describe the longitudinal disease course and pulmonary outcomes of North American patients with melanoma differentiation–associated protein 5 (MDA5) antibody–associated dermatomyositis (DM). Methods Thirty patients with MDA5 antibody–associated DM were identified in a single‐center longitudinal cohort of 352

Insect Science, 2017 The frugivorous 'true' fruit fly, Bactrocera tryoni (Queensland fruit fly), is presumed to have a non-resourced-based lek mating system. This is largely untested, and contrary data exists to suggest Bactrocera tryoni may have a resource-based mating ...

Current Biology, 2022
Most vertebrates, including all mammals and birds, are sexually reproducing organisms. The implication of sexual reproduction is that an adult bird exists because a male transferred sperm to the reproductive tract of a female during copulation, one of the sperm fertilized an egg, and the ensuing embryo developed into an individual male or female that ...

This chapter looks into the evolution of mating systems, which relate to social associations and the number of sexual partners of an animal during a breeding season. It explains how animals showcase different mating systems and their selection of mates to maximize their fitness.

New Phytologist, 2010 Reduced allocation to structures for pollinator attraction is predicted in selfing species. We explored the association between outcrossing and floral display in a broad sample of angiosperms.

Coalition formation in the cheetah is considered to enhance male reproductive success, although no evidence to support this was gleaned in this study. Females advertised oestrus by spray-urinating and often undertook extensive movements at this time. Additionally some evidence for mating rendezvous areas was obtained.

The study of mating is one of the most active areas in evolutionary ecology. What fuels this research is curiosity about a stunning diversity of ways in which zygotes are formed. Many plants and some animals can reproduce without combining gametes. Many other plants combine gametes but do so within the same individual (selfing).

Modeling Mate Choice in Monogamous Mating Systems with Courtship
Adaptive Behavior, 2002We present a conceptual framework for the study of mate choice in monogamous mating systems with non-negligible courtship time. Within this framework, we develop a mate choice model for the common case where individuals have a changing social network of potential partners.

Abstract Defining a population mating strategy has inherent problems. All individuals are of different quality and face unique conditions during reproduction. Thus, the costs and benefits for specific individuals must be considered when examining their mating arrangement.
