FIRST SOUTH AMERICAN RECORDS OF HOLOCNEMUS PLUCHEI (SCOPOLI, 1763) AND SPERMOPHORA SENOCULATA (DUGÉS, 1836) (ARANEAE: PHOLCIDAE)
(Universidad de Concepción.Facultad de Ciencias Naturales y Oceanográficas., 2008)
Female secondary sexual traits in spiders: Adaptive interpretations of the sternum projection in the pholcid Holocnemus pluchei
(Elsevier Gmbh, 2019-10)
Sexually dimorphic traits are the outcome of a network of selective pressures acting upon each sex. While male secondary sexual traits are frequently restricted to intrasexual competition, female ornaments or weapons are ...
Selección sexual post-cópula en Pholcidae y otras arañas Haploginas
(2014)
La elección críptica femenina en arañas puede implicar muchos mecanismos para sesgar la paternidad de un macho, como: terminar anticipadamente la cópula, probabilidad de aparearse nuevamente, expulsión de esperma, entre otros.
A parental care-mating dilemma? Potential risks for offspring in the Pholcid spider when egg-carrying females accept mating
(Springer/Plenum Publishers, 2017-03)
Many species face a trade-off between additional mating opportunities and the offspring benefits (viability, quality) provided by parental care. Female Holocnemus pluchei spiders must abandon their egg-sac, which they ...
Consistency of females’ stridulatory behaviour during inter-sexual interactions in spiders
(Wiley Blackwell Publishing, Inc, 2019-08-06)
In a sexual context, it is expected that females base their choice of mate on the behaviours that males perform during courtship, as such behaviours are associated with the male's mate quality. Stridulation is one form of ...
Patterns of sperm transfer behavior in a pholcid spider with two distinct copulatory phases
(Springer New York LLC, 2018-11)
Sexual selection is the responsible force for the evolution and maintenance of genital diversity and function. This is the case for example, of genital movements performed by males during mating and copulation duration. ...
¿Influye el tamaño de la araña Holocnemus pluchei en los comportamientos de apareamiento?
(2013)
La selección a través de la competencia entre machos por las oportunidades de apareamiento
favorece un tamaño corporal grande en varias especies de arañas. El tamaño de los machos
puede ser una ventaja para prevenir la ...
Modificaciones somáticas intersexuales influenciadas por la posición de cópula en la araña Holocnemus pluchei (PHOLCIDAE)
(2014)
Existe consenso en que el desarrollo de un rasgo morfológico es el resultado de un conjunto de presiones selectivas influenciadas por demandas conflictivas de origen ontogenético y por el efecto de interacciones ...
Copulatory behaviour increases sperm viability in female spiders
(Wiley Blackwell Publishing, Inc, 2020-09-20)
One remarkable reproductive feature in animals with internal fertilization is a reduction in sperm viability over time in females. Whether this reduction is driven by male-male competition and/or cryptic female choice is ...
Sperm viability in spiders: A first approach using Holocnemus pluchei (Scopoli, 1763) (Synspermiata: Pholcidae)
(American Arachnological Society, 2019-04-27)
Several studies have shown that sperm viability (SV) is a key trait during sexual competition. However, this has not yet been tested in spiders as no protocol has been developed to quantify SV. Here, we describe a methodology ...
