“…Finally, human-manufactured objects have also created new environments to be exploited (metal and glass used as anchor points for webs of orb-weaving spiders (Araneus diadematus) [136]) and even new signals themselves (objects such as pens and clothespins used as bower bird ornaments or incorporation of compounds for herbicides in orchid bee courtship chemical cues [49]). Human-manufactured chemicals that are released into the environment also appear to affect receiver preferences; synthetic oestrogen affects female [139,140] and male preferences [141]. It is important to ascertain at what level (i.e.…”

The diversity of signalling traits within and across taxa is vast and striking, prompting us to consider how novelty evolves in the context of animal communication. Sexual selection contributes to diversification, and here we endeavour to understand the initial conditions that facilitate the maintenance or elimination of new sexual signals and receiver features. New sender and receiver variants can occur through mutation, plasticity, hybridization and cultural innovation, and the initial conditions of the sender, the receiver and the environment then dictate whether a novel cue becomes a signal. New features may arise in the sender, the receiver or both simultaneously. We contend that it may be easier than assumed to evolve new sexual signals because sexual signals may be arbitrary, sexual conflict is common and receivers are capable of perceiving much more of the world than just existing sexual signals. Additionally, changes in the signalling environment can approximate both signal and receiver changes through a change in transmission characteristics of a given environment or the use of new environments. The Anthropocene has led to wide-scale disruption of the environment and may thus generate opportunity to directly observe the evolution of new signals to address questions that are beyond the reach of phylogenetic approaches.

“…17a-Ethinylestradiol, a synthetic form of estrogen commonly used in birth control pills, had already been shown to reduce courtship behavior and aggression in males. Dzieweczynski showed that it affects females as well [4]. "Historically it was thought that males were the only ones being impacted by estrogen mimics because females have a feedback loop -if they have too much estrogen the body stops producing it", she explained.…”

“…Previous research has shown that female exposure to EE2 may increase receptivity in females when choosing a mate (Cram et al., 2019 ; Saaristo et al., 2019 ). However, non‐exposed females discriminate against males that have been exposed to environmental estrogens based on changes in male courtship (Dzieweczynski & Kane, 2017 ). Here, we exposed both male and female minnows to MPs for 30 days, and then tested them in dual‐choice trials to determine whether exposure to MPs, alone or in conjunction with EE2, impaired male courtship behavior and/or the outcome of female mate choice decisions.…”

Microplastics (MPs) have become an environmental concern in recent years, with most research focused on the physiological effects of exposure. Comparatively little consideration has been given to the potential behavioral impacts of exposure, which may also have fitness consequences for individuals. Moreover, MPs can serve as vectors for endocrine‐disrupting chemicals and other locally co‐occurring contaminants known to impair behavioral responses. This project aimed to determine whether MPs alone or in association with a common environmental EDC (17‐alpha ethinyl estradiol; EE2) alter reproductive behavior and decision‐making in fish. Male and female fathead minnows (Pimephales promelas) were exposed to MPs associated with either a low (10 ng/L; MPEE2 10) or high (50 ng/L, MPEE2 50) concentration of EE2, or MPs without EE2 (MPvirgin) for 30 days via a dietary feeding protocol. Behavioral trials were conducted on Day 31 to determine the effects of exposure on male–female social interactions. The expression of male sexually selected traits, including courtship, was unaffected by exposure. However, non‐exposed females in all treatment groups trended toward discrimination against exposed males, which reached statistical significance for the MPEE2 50 group. Female fish exposed to MPs, alone or in association with EE2, were equally likely to approach and associate with non‐exposed and exposed males. The results from this study suggest that MPs may alter social behavior in fishes and that the behavioral impacts of exposure may be more strongly pronounced in females than males. Such individual‐level changes in fitness have the potential to impact population size, with downstream effects on the broader aquatic community.
