“…pupfishes: Kodric-Brown and West, 2014; woodrats: Shurtliff et al, 2013). For deer, preferences for interspecific male vocalizations differ for red and sika females (Wyman et al, 2014). However, our results did not show significant differences in copulation probability between the two heterospecific female-male combinations, suggesting that the barrier is probably similarly weak between both species.…”

Weak premating isolation between two parapatric brocket deer species

Brocket deer Mazama nemorivaga and M. gouazoubira occur at the Amazon basin and southern areas, respectively, in parapatric distribution ranges. Both species can interbreed in captivity, although hybrids have serious fertility problems. Therefore, we expect natural selection to favour behavioural barriers against interspecific mating. We carried out no-choice tests with individuals of both species in captivity, along with white-tailed deer (Odocoileous virginianus) as outgroup. Behaviours were video recorded and analysed by using Generalized Mixed models, with interacting females and males as random subjects. Trials never led to copulation when the white-tailed-deer male was involved. Copulations within brocket deer species were more likely to occur when the individuals belonged to the same species (82.4%) but they also occurred quite frequently in interspecific interactions (35.7%). We identified some courtship behaviours, in males and females, which associated with a higher copulation probability or showed differences in frequency when performed to partners of the same or different species. In conclusion, our results reveal that the occurrence of facilitating behaviours and copulations were more common in intraspecific interactions, evidencing discrimination between species, but also that the precopulatory barrier was not strong between both brocket deer species.

“…Lowe and Gardiner () reported intermediate craniological morphology for putative hybrids in the Lake District, and in a well‐documented hybrid swarm in County Wicklow (Ireland), Harrington () observed a general merging of size and pelage of animals in the region. Similarly, vocalizations of red deer‐sika hybrids are intermediate between parental species (Long, Moore, & Hayden, ; Wyman, Locatelli, Charlton, & Reby, ). Carcass weight, jaw length, and incisor arcade breadth are all greater in sika‐like hybrids than in “pure” sika and lower in red deer‐like hybrid females than in “pure” red deer females (for definition of “pure”; see Senn, Swanson et al.…”

Since the mid‐19th century, multiple introductions of Japanese sika deer (Cervus nippon nippon) and North American wapiti (C. canadensis) have taken place in the British Isles. While wapiti have generally been unsuccessful, sika have been very successful, especially in Scotland where they now overlap at least 40% of the range of native red deer (C. elaphus). Hybridization between these two species and red deer has been demonstrated in captivity and in the wild. Using a panel of 22 microsatellite loci that are highly diagnostic between red deer and sika, and moderately diagnostic between red deer and wapiti, we investigated the extent of introgression between these species in 2,943 deer sampled from around Scotland and from the English Lake District using the Bayesian clustering software STRUCTURE. We also used a diagnostic mitochondrial marker for red deer and sika. Our survey extends previous studies indicating little introgression of wapiti nuclear alleles into red deer, in particular in Northern Scotland, Kintyre, and the Lake District. We found a new area of extensive sika introgression in South Kintyre. In the North Highlands, we show for the first time geographically scattered evidence of past hybridization followed by extensive backcrossing, including one red‐like individual with sika introgression, two sika‐like individuals with red deer introgression, and six individuals that were apparently pure sika at the nuclear markers assessed but which carried red deer mitochondria. However, there has not been a collapse of assortative mating in this region. Similarly, in the English Lake District red deer, we found only traces of past sika introgression. No sika alleles were detected in the Central Highlands or the Hebridean red deer refugia. We make suggestions for management to prevent further spread of sika alleles into red deer and vice versa.

“…As sexual interactions usually involve a rich communicatory exchange (Coyne & Orr, ), in some scenarios multiple signals are used to recognize conspecifics, whereas in others a single signal can give information about more than one individual trait, such as sexual identity and mate quality (Candolin, ; Hebets & Papaj, ; Rypstra et al ., ). Sometimes, only some communication channels are involved in species recognition and they can be in conflict with those channels concerning mate choice (Leonard & Hedrick, ; Velásquez et al ., ) or lead to potential misleading recognition, especially between closely related species (Wyman et al ., ). Spiders with complex courtship behaviours (involving more than one communication channel), such as salticids, agelenids, and lycosids, have been considered good candidates for studying the function of the different communication signals (Uetz & Denterlein, ; Costa & Capocasale, ; Hebets & Uetz, ; Elias, Hebets & Hoy, ; Galasso, ; Chiarle & Isaia, ).…”

Reproductive isolation between two populations ofAglaoctenus lagotis, a funnel-web wolf spider

Aglaoctenus lagotis (Lycosidae: Sosippinae) is a spider that, in contrast to the predominant wandering habit of the family, constructs funnel webs. The species is widely distributed throughout the Neotropics and is credited with high levels of intraspecific variation. Here, we evaluate whether reproductive isolating barriers operate between some populations of A. lagotis. We used heterotypic encounters between individuals from two distant localities: southern Uruguay (SU) and Central Argentina (CA). Additionally, we used spiders from an intermediate locality, western Uruguay (WU), where both forms of the species overlap (SU.WU was used to describe individuals from WU reminiscent of those from SU; and CA.WU was used to describe individuals from WU reminiscent of those from CA). No copulations occurred between SU and CA individuals, whereas a single and atypical copulation occurred between SU.WU and CA.WU individuals. Attacks (only by females on males) were rare. In tests of choice based on silk cues, SU males did not prefer homotypic cues but almost did not court CA females, whereas CA males preferred homotypic cues but usually courted heterotypic females. These findings, with a previously reported temporal asynchrony between populations, suggest the occurrence of reproductive isolation between both spider forms and a speciation process favoured by the wide distribution and plasticity of the species. © 2015 The Linnean Society of London, Biological Journal of the Linnean Society, 2015, 114, 646–658.
