Effects of maternal care on the lifetime reproductive success of females in a neotropical harvestman.
1. Few studies have experimentally quantified the costs and benefits of female egg-guarding behaviour in arthropods under field conditions. Moreover, there is also a lack of studies assessingExpand

Five new cases of paternal care in harvestmen (Arachnida: Opiliones): implications for the evolution of male guarding in the Neotropical family Gonyleptidae
TLDR
In this paper, we present field observations on paternal care in five species of harvestmen belonging to the family Gonyleptidae and examine the extent to which the available data can be used to test a recent theory on the evolution of exclusive male care via sexual selection. Expand

Mating behavior of a Neotropical arachnid with exclusive paternal care
Paternal care has independently evolved in several arthropod lineages, but mating interactions have been described in detail for only a few species. Here, we describe the mating behavior ofExpand

Efficiency of uniparental male and female care against egg predators in two closely related syntopic harvestmen
Although the benefits of maternal care have been investigated in many species, the caring role of males in species with exclusive paternal care has received less attention. We experimentallyExpand

Paternal Care Decreases Foraging Activity and Body Condition, but Does Not Impose Survival Costs to Caring Males in a Neotropical Arachnid
Exclusive paternal care is the rarest form of parental investment in nature and theory predicts that the maintenance of this behavior depends on the balance between costs and benefits to males. OurExpand

Female sperm use and storage between fertilization events drive sperm competition and male ejaculate allocation
Sperm competition theory has traditionally focused on how male allocation responds to female promiscuity, when males compete to fertilize a single clutch of eggs. Here, we develop a model to ask howExpand

Conditional male dimorphism and alternative reproductive tactics in a Neotropical arachnid (Opiliones)
In arthropods, most cases of morphological dimorphism within males are the result of a conditional evolutionarily stable strategy (ESS) with status-dependent tactics. In conditionally male-dimorphicExpand

Costs and benefits of temporary egg desertion in a rocky shore frog with male-only care
Egg attendance imposes costs on parents, including decreased food intake and increased mortality risks. By concentrating parental activities when egg predation is greater and abiotic conditions areExpand

Male and female mate choice in harvestmen: General patterns and inferences on the underlying processes
Harvestmen belong to the order Opiliones , and, unlike other arachnids, they are highly polygynandrous , with both males and females mating multiply throughout the breeding season. In this chapter,Expand

Effects of egg attendance on male mating success in a harvestman with exclusive paternal care
The expected quality of paternal behavior can influence female mating decisions and determine male mating success. We evaluated the importance of oviposition site quality, male body size, parentalExpand
