Talk:Broadnosed pipefish

Untitled

Peer Editing Round 2: Great information added to this fish species! Global edit = Under the reproduction section, the multiple paragraphs seem jumping and short. I would try to name the section with more detail such as Mating system (when talking about polyandry and mating season) and then Mating behaviors (when talking about courtship between male and female pipefish) Local edit = In second paragraph under reproduction section, there is a word missing ("until the ...delivers her eggs")Jenniehorstmann (talk) 17:59, 27 March 2017 (UTC)Jennie Horstmann

There is very little information on the broad-nosed pipefish (Syngnathus typhle) here on Wikipedia, especially in terms of mating. Some of the topics I hope to add to the article are: courtship and copulation behaviors (dance, fertilization), sexual role reversal (male brood pouch, male pregnancy, males providing all parental care), polygynandry, males limiting female reproductive success (females competing for access to males), female ornamentation (sexual selection, Bateman’s 3rd principle), effect of size on male and female reproductive success, selective abortion by males Akl95 (talk) 02:16, 16 February 2017 (UTC)

A brief outline of some of the topics I hope to address:

Broad-nosed pipefish are a sex-role reversed species

- Males possess a pouch with two ventral folds, where fertilization occurs

- Male pregnancy

- Males provide all parental care

- Source: “The Genetic Mating System of a Sex-Role-Reversed Pipefish (Syngnathus typhle): A Molecular Inquiry”

- Source: "Reproductive Costs in Two Sex-Role Reversed Pipefish Species (Syngnathidae)"

Males limit female reproductive success

- One male cannot fertilize and carry all the eggs of a similarly-sized female

- Source: "Male Limitation of Female Reproductive Success in a Pipefish: Effects of Body-Size Differences"

Female ornamentation

- Sexual selection

- Bateman’s third principle

- Source: "Male pipefish prefer ornamented females”

- Source: "The Bateman Gradient and the Cause of Sexual Selection in a Sex-Role- Reversed Pipefish"

- Source: "The Measurement of Sexual Selection Using Bateman's Principles: An Experimental Test in the Sex-Role-Reversed Pipefish Syngnathus typhle"

Courtship and copulation

- Females court males with dancing

- Females release eggs into male brood pouch

- Male assumes a characteristic shape while fertilizing the eggs

- Source: "Pipefish Courtship and Copulation"

Broad-nosed pipefish mating system

- Polygynandrous

- Source: "The Genetic Mating System of a Sex-Role-Reversed Pipefish (Syngnathus typhle): A Molecular Inquiry"

Effect of size on male and female RS

- Males prefer large females and females prefer large males

- Source: “Reproductive Compensation in Broad-nosed Pipefish Females”

Male and female compensatory reproductive strategies

- Females provide smaller (lower-quality) mates with more proteinaceous eggs

- Males selectively absorb the eggs of lower-quality females

- Source: “Evolutionary biology: Pregnant fathers in charge”

- Source: “Reproductive Compensation in Broad-nosed Pipefish Females”

Embryo resource competition

- In mixed-size-egg broods, large eggs are more competitive than small eggs for resources and are more likely to survive

- Source: “Apparent Resource Competition among Embryos in the Brood Pouch of a Male Pipefish”
