Condition Does Not Alter Responsiveness to Mating Signals in Female Pacific Field Crickets Open
Animals often vary in their condition (i.e. the amount of resources allocatable to fitness-related functions) and such variation can influence the expression of important mating behaviors like how quickly individuals respond to mating sign…

Perceived mate availability does not influence variation in egg-laying patterns in the Hawaiian Pacific field cricket (Orthoptera: Gryllidae) Open
Females may adjust how many eggs they lay over the course of their lifetime ( i.e ., their egg-laying pattern) to bias their investment into either current or future reproduction. Using mate availability cues to bias reproductive investmen…

Male crickets in poor condition engage in less same-sex sexual behavior Open
Same-sex sexual behavior (SSB) is widespread among animals and is often treated as an evolutionary anomaly or mistake. An alternative view is that SSB occurs because individuals have broader or more permissive “mating filters.” A broader f…

Reproductive biology of Hawaiian lava crickets Open
Insects have spread across diverse ecological niches, including extreme environments requiring specialized traits for survival. However, little is understood about the reproductive traits required to facilitate persistence in such environm…

Machine learning reveals singing rhythms of male Pacific field crickets are clock controlled Open
Circadian rhythms are ubiquitous in nature and endogenous circadian clocks drive the daily expression of many fitness-related behaviors. However, little is known about whether such traits are targets of selection imposed by natural enemies…

Meta‐analytical evidence that males prefer virgin females Open
Males are often predicted to prefer virgin over non‐virgin females because of the reduced risk of sperm competition. Does this prediction hold across studies? Our systematic meta‐analysis of 138 studies, mainly conducted in invertebrates, …

Rethinking same-sex sexual behaviour: male field crickets have broad mating filters Open
Same-sex sexual behaviour (SSB) occurs in many animals and is often treated as an anomaly requiring special explanation. One common explanation for SSB is mistaken identity. However, animals make similar ‘mistakes’ in other contexts—such a…

Unlike a virgin: a meta-analytical review of female mating status in studies of female mate choice Open
Studies of female mate choice commonly use virgin females as test subjects, either to control for the effects of mating or because virgin females are presumed to be more responsive to mating cues. Theory predicts that virgin females will b…

How urbanization affects sexual communication Open
Urbanization is rapidly altering landscapes worldwide, changing environmental conditions, and creating novel selection pressures for many organisms. Local environmental conditions affect the expression and evolution of sexual signals and m…

Sex‐specific associations between life‐history traits and a novel reproductive polymorphism in the Pacific field cricket Open
Associations between heritable polymorphisms and life‐history traits, such as development time or reproductive investment, may play an underappreciated role in maintaining polymorphic systems. This is because selection acting on a particul…

Immunogenetic and tolerance strategies against a novel parasitoid of wild field crickets Open
Among the parasites of insects, endoparasitoids impose a costly challenge to host defenses because they use their host’s body for the development and maturation of their eggs or larvae, and ultimately kill the host. Tachinid flies are high…

Killing the Behavioral Zombie: Genes, Evolution, and Why Behavior Isn’t Special Open
The nature–nurture controversy seems to be a scientific zombie, an idea that will not die despite ample evidence that it is inaccurate and even damaging to our ideas about how characteristics evolve. The dilemma is particularly clear with …

Direct and indirect effects of sexual signal loss on female reproduction in the Pacific field cricket (<i>Teleogryllus oceanicus</i>) Open
Sexual signal evolution may present fitness consequences for the non‐signaling sex due to shared genes and altered social conditions, but this is rarely studied in natural populations. On the Hawaiian Island of Kauai, most male Teleogryllu…

When Does Sexual Signal Exploitation Lead to Signal Loss? Open
Evolutionary loss of traits is common over evolutionary time and occurs in diverse taxa. Sexual signals and other non-signal traits should differ in their likelihood of becoming lost because they experience different selection pressures co…

Most studies on the evolution of migration focus on food, mates and/or climate as factors influencing these movements, whereas negative species interactions such as predators, parasites and pathogens are often ignored. Although infection a…
