Exaggerated evolution of male armaments via male–male competition
Ecology and Evolution, 2021 AbstractMales usually compete to gain access to prospective mates. Through this male–male competition, superior males have a higher chance of passing on their traits to the next generation of male offspring. One category of male traits is armaments, which are weapons used during competition, for example, the chelae of fiddler crabs and the antlers of ...

Male–male interactions select for conspicuous male coloration in damselflies [PDF]
Animal Behaviour, 2020 AbstractMale ornamentation, such as conspicuous male colouration, can evolve through female mate choice. Alternatively, in species without overt female mate preference, conspicuous male colouration can evolve via intrasexual selection to resolve male-male competition or to prevent costly male-male mating attempts.

Male tolerance and male–male bonds in a multilevel primate society [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Recent theoretical approaches to understanding the evolution of cooperation point to a close link between spatial structure and cooperative tendencies and question the importance of kin relations. We here show that Guinea baboon males living in a multilevel society maintain strong male bonds, irrespective of relatedness, and ...

Archives of Endocrinology and Metabolism, 2022 Osteoporosis, a disease classically attributed to postmenopausal women, is underappreciated, underdiagnosed, and undertreated in men. However, it is not uncommon for osteoporotic fractures to occur in men. About 40% of fractures occur in men with an incidence that has increased over the years.

Reversible switches between male–male and male–female mating behaviour by male damselflies [PDF]
Biology Letters, 2005 For many animal groups, both sexes have been reported to attempt to mate with members of their own sex. Such behaviour challenges theories of sexual selection, which predict optimization of reproductive success. We tested male mate choice between opposite- and same-sex members in the damselfly Ischnura elegans ...

Synchrony on the reef: how environmental factors shape coral spawning patterns in Acropora corals in the Maldives [PDF]
PeerJElucidating our knowledge on the reproductive phenology of scleractinian corals and the environmental drivers of reproductive synchronicity is pivotal for assessing gene flow between populations and the potential for ecosystem recovery.

Isolated unilateral temporalis muscle hypertrophy: first case in an Indo-Aryan
Nepal Journal of Neuroscience, 2020 Unilateral hypertrophy of temporalis muscle (isolated type) is extremely rare and only 14 cases have been reported in English literature since 1990. Although no definitive etiology is identified, stress and bruxism are among the many factors are linked ...

The norm of polynomials in large random and deterministic matrices [PDF]
, 2011 Let X_N= (X_1^(N), ..., X_p^(N)) be a family of N-by-N independent, normalized random matrices from the Gaussian Unitary Ensemble. We state sufficient conditions on matrices Y_N =(Y_1^(N), ..., Y_q^(N)), possibly random but independent of X_N, for which ...
