“…As well as limiting ranges, behavioral interference has been implicated in some ongoing species replacements [4,7,15,48,49]. Aggressive interference in conjunction with habitat changes appears to account for the cyclical replacement of mountain bluebirds (Sialia currucoides) by western bluebirds (Sialia mexicana) in the northwestern USA [15].…”

“…Mismatches of fundamental versus realized altitudinal distributions provide indirect evidence of behavioral interference, and greater mismatch in one species suggests that aggressive interactions are asymmetrical [47]. These scenarios raise the prospect under climate change of subordinate high-elevation species being squeezed into extinction if dominant low-elevation species shift upslope, or of dominant highelevation species preventing the upward movement of subordinate species, which are then left occupying a physiologically suboptimal habitat [17,19].As well as limiting ranges, behavioral interference has been implicated in some ongoing species replacements [4,7,15,48,49].

“…Aggressive interference in conjunction with habitat changes appears to account for the cyclical replacement of mountain bluebirds (Sialia currucoides) by western bluebirds (Sialia mexicana) in the northwestern USA [15]. Likewise, aggressive and reproductive interference combined with climate change appear to be driving the replacement of pied flycatchers (Ficedula hypoleuca) by collared flycatchers (Ficedula albicollis) on the Swedish Island of Öland [16,48].Species replacements can also be affected by how standing behavioral variation within the invading population is spatially structured [15,[50][51][52]. For example, male western bluebirds at the invasion front are more aggressive than those in the resident population [15].…”

Behavioral interference between species, such as territorial aggression, courtship, and mating, is widespread in animals. While aggressive and reproductive forms of interspecific interference have generally been studied separately, their many parallels and connections warrant a unified conceptual approach. Substantial evidence exists that aggressive and reproductive interference have pervasive effects on species coexistence, range limits, and evolutionary processes, including divergent and convergent forms of character displacement. Alien species invasions and climate change-induced range shifts result in novel interspecific interactions, heightening the importance of predicting the consequences of species interactions, and behavioral interference is a fundamental but neglected part of the equation. Here, we outline priorities for further theoretical and empirical research on the ecological and evolutionary consequences of behavioral interference. Interspecific Aggression and Reproductive InterferenceFew subjects in animal behavior have attracted more attention than aggression and sex, yet research tends to stop at species boundaries even when the behaviors themselves do not. Aggressive and sexual interactions between species are surprisingly common and share many parallels in their causes and ecological and evolutionary effects [1][2][3][4][5][6]. Both types of behavioral interference (Box 1) have been hypothesized to: (i) arise as a byproduct of intraspecific interactions (Box 2); (ii) cause local extinction as well as temporal and spatial habitat partitioning; (iii) prevent species from coexisting that otherwise would be expected to coexist; (iv) enable coexistence between species that otherwise would not be expected to coexist; (v) promote or prevent species range shifts and the spread of invasive species; (vi) cause sympatric species to diverge or converge through character displacement processes; (vii) cause populations within a species to diverge from each other due to character displacement in areas of sympatry; and (viii) contribute to reproductive isolation and speciation ( Figure 1).Despite their connections, aggressive interference and reproductive interference (see Glossary) have largely been studied by different researchers in relation to different theoretical frameworks [2,4,7] and in different study systems [3], even though many closely related species interfere with each other in both ways (see Table S1 in [8]). We do not believe that these two categories of interspecific interactions should be synonymized, because this would obscure important differences between them. Instead, we propose that their similarities and interrelationships merit a common conceptual framework, which we introduce here ( Figure 1). TrendsAggressive and reproductive forms of behavioral interference between species are widespread in animals and share many parallels in their underlying causes and their ecological and evolutionary effects.Behavioral interference can determine whether species coexist and, thus, affects speci...

“…Nowadays, after a massive body of work on this topic, and especially due to the advent of molecular genetic tools, hybridization and heterospecific interactions have provided insights to speciation and are recognized as a powerful evolutionary force. For example, we now know that heterospecific interactions have the potential to affect species coexistence and evolution of populations (Ribeiro and Spielman 1986, Gröning and Hochkirch 2008, Schwenk et al 2008, Vallin et al 2012. When populations of the same species begin to diverge, due to selection or random processes, reproductive isolation starts to accumulate between them (Coyne and Orr 2004).…”

The effect of male-male competition and ornament size on mean and variance of courtship intensity towards heterospecific and conspecific females

As species do not live in isolation from each other, they are faced with an elementary choice when searching for a mating partner: a choice between conand heterospecific individuals. Despite the remarkable research effort on hybridization and its avoidance, there are still some less well covered areas, e.g. what is the role of males in hybridization, what patterns are found in sympatric wild populations, what role do alternative reproductive tactics (ARTs) have on the likelihood of heterospecific matings, and what are the true costs of heterospecific interactions. In this thesis I first quantify the frequency of hybridization, backcrossing and heterospecific matings in sympatric wild populations of Calopteryx splendens and C. virgo damselflies in Finland. The possible influence of population densities, relative abundances of the species, and operational sex ratios on the frequency of heterospecific matings is also investigated. The second aim is to investigate how the intensity of territorial competition influences males' reproductive response to a heterospecific female. Finally, I dissect the importance of male ARTs on hybridization propensity and I attempt to quantify the reproductive costs that males' hybridization propensity inflicts among the tactics. The results imply a major role for C. splendens males in heterospecific reproductive interactions between the study species. Especially territorial males seem to be prone to hybridization, and the prevalence of hybridization is increased with a high availability of C. virgo females. Hybridization seems to be costly because there was high discordance between heterospecific mating frequency and observed numbers of hybrids. However, heterospecific courtship did not reduce conspecific mating success. The results also show that C. splendens males are able to adjust their level of heterospecific courtship according to the competitive environment as well as to the ART it follows. My thesis is a step towards understanding the causes of species reproductive interactions in wild populations.

Reproductive interference is interspecific sexual interactions that are costly to at least one species involved. Although many studies have reported a substantial fitness cost associated with reproductive interference, suggesting its ecological significance, others have not observed reproductive interference in study species. Reproductive interference that incurs a large fitness cost is more likely to occur during secondary contacts than between long‐coexisting species. I first explain the rationale underlying this prediction using existing literature. Next, I present a conceptual framework to classify pairs of interacting species into one of four states, defined by the ecological and evolutionary stabilities of the species pairs. I discuss how the stability states of species pairs are likely to change over time, along with changes in the demographic and evolutionary role of reproductive interference. I then perform literature survey to test the prediction that reproductive interference should be more prevalent in secondary contact. Finally, I discuss the implications of the proposed conceptual framework and literature survey result.
