摘要除了它们的电器官放电，两种西非的鱼在繁殖过程中还能发出声音。在这里，我们记录的繁殖行为和并发发声记录在圈养标本的新物种Pollimyrus玛丽安从赞比西河上游。在产卵之前，三只雄性玛丽安建立了一个领地，并建立了一个由丝状植物材料制成的巢穴（在后期阶段可以容纳卵和幼虫）。从领地建立开始，通常在夜间，只有雄性产生两种不同的发声，一种是音调性呻吟（平均持续时间，2.26 ± SD 0.6 s），另一种是刺耳的咕噜声（0.596 ± SD 0.029 s;咕噜声脉冲重复率，PRR，32.1 ± SD 1.24 Hz，25.4 ± SD 0.15 °C）。这两种发声类型与两种西非物种P. isidori和P. adspersus的记录相似，但明显不同，它们的脉冲重复率（PRR）分别高出25%和60%（在相似的温度下）。在标准长度不变的情况下，雄性P. marianne的一些声音特征在两年中只有轻微的变化，但明显取决于水温。当没有其他鱼在场时，三只雄性只偶尔发出呻吟。然而，当女性来访时，男性产生了长时间的呻吟序列，并叠加了咕噜声（呻吟-咕噜声发作;平均持续时间，14.69 ± SD 2.2 s）。发声的最大速率发生在产卵前的夜晚，这一速率消退时，幼虫在巢中，和发声后，幼虫终于停止了分散。当雌性重新开始访问巢穴时，发声率再次增加。很久以前，也是在繁殖之后，领土男性发出呻吟声和一些咕噜声，当领土入侵者引起不断升级的争斗互动，与许多咬或屁股。在竞争的情况下，呻吟的持续时间，呻吟的峰值振幅频率和呼噜声脉冲重复率不同于求爱期间产生的声音。在P. marianne中，在生殖和竞争相互作用中产生的声音表明了双重功能：吸引配偶和威胁竞争的雄性，或者潜在的吃卵雌性。
ABSTRACT In addition to their electric organ discharges, two West African mormyrid species are known to generate sounds during reproduction. Here, we document the reproductive behaviour and concurrent vocalisations recorded in captive specimens of the new species Pollimyrus marianne from the Upper Zambezi River. Prior to spawning, three male P. marianne established a territory and built a nest of filamentous plant material each (that would hold eggs and larvae at a later stage). Beginning with territory establishment and usually at night, only the males generated two distinct vocalisations, a tonal moan (average duration, 2.26 ± SD 0.6 s), and a harsh grunt (0.596 ± SD 0.029 s; grunt pulse repetition rate, PRR, 32.1 ± SD 1.24 Hz at 25.4 ± SD 0.15 °C). Both vocalisation types were similar to, but clearly different from, those recorded in the two West African species, P. isidori and P. adspersus, the PRR (Pulse Repetition Rate) of which were higher by 25% and 60%, respectively (at similar temperature). At constant standard length, some of a male P. marianne's sound characteristics varied only slightly over two years, but depended clearly on water temperature. When no other fish were present, the three males produced moans only sporadically. When, however, females were visiting, the males generated long-lasting moan sequences that were superimposed by grunts (moan-grunt bouts; average duration, 14.69 ± SD 2.2 s). The maximum rate of vocalisation occurred in the nights immediately before spawning; this rate receded when larvae were present in the nest, and vocalisations finally stopped after the larvae had dispersed. Vocalisation rate increased again when females restarted to visit the nest site. Long before and also after reproduction, territorial males vocalised with moans and some grunts, when territory intruders evoked escalating agonistic interactions that were correlated with many bites or butts. In agonistic contexts, moan duration, moan peak amplitude frequency and grunt pulse repetition rate differed from the sounds produced during courtship. In P. marianne, the generation of sounds during reproductive and agonistic interactions suggests a dual function: attraction of mates and threatening competing males, or potentially egg-eating females.
