Knowledge of how animals use behaviour to adapt to changing environmental conditions is important for understanding how they will be impacted by climate change. Rising global temperatures are increasing the moisture-holding capacity of air, leading to greater cloud cover, which attenuates shortwave radiation, reducing the amount of radiation reaching animals on the ground. We experimentally investigated how changes in cloud cover may impact ectotherms that bask in sunshine to regulate their body temperature. We manipulated the degree of shade experienced by an annual insect, the field cricket, Gryllus campestris, under natural and seminatural conditions. Shading nymphs in large field boxes did not affect development time and had only a small negative effect on mass at maturity. To investigate whether crickets were able to compensate for increased shade through changes in their behaviour, we monitored the activity of experimentally shaded and unshaded wild cricket nymphs. Unshaded nymphs sought shade at midday, whereas shaded nymphs basked throughout the day in the most sunlit positions. Most ectotherms are profoundly affected by the energy they receive from sunlight. Our findings suggest that mobile ectotherms may be able to compensate for changes in cloud cover. However, they may incur costs due to greater exposure to threats such as predation. Understanding behavioural flexibility and the costs and benefits of different strategies is required to make accurate predictions about how terrestrial ecosystems will be impacted by changing solar insolation due to climate change.

了解动物如何利用行为来适应不断变化的环境条件，对于了解它们将如何受到气候变化的影响非常重要。全球气温上升使空气的含水量增加，导致云量增加，从而衰减了短波辐射，减少了到达地面动物的辐射量。我们通过实验研究了云层的变化会如何影响那些通过沐浴阳光来调节体温的外温动物。我们在自然和半自然条件下操纵了一年生昆虫田蟋的遮阴程度。在大型田间箱中遮蔽若虫不会影响发育时间，对成熟时的质量也只有很小的负面影响。为了研究蟋蟀是否能够通过改变行为来补偿遮荫的增加，我们监测了实验中被遮荫和未被遮荫的野生蟋蟀若虫的活动。未受遮蔽的若虫在正午时寻找阴凉处，而受遮蔽的若虫则全天都在阳光最充足的位置晒太阳。大多数外温动物都会受到它们从阳光中获得的能量的深刻影响。我们的研究结果表明，移动的外温动物可能能够补偿云层的变化。不过，它们可能会因为更容易受到捕食等威胁而付出代价。要准确预测陆地生态系统将如何受到气候变化引起的太阳日照变化的影响，就必须了解行为的灵活性以及不同策略的成本和收益。

Human presence and urbanization alter many species' vulnerability and perceived risk, but little research has investigated how anthropogenic impacts affect behaviour in dynamic defensive mutualisms. As human activities continue to expand in marine communities, it is important to understand how they may affect risk assessment in behaviourally dependent symbionts. Shrimpgobies (Ctenogobiops spp.) and snapping shrimp (Alpheus spp.) in Mo'orea, French Polynesia participate in an obligate, symbiotic relationship in areas where humans recreate. We quantified hiding time, flight initiation distance and time allocated to different behaviours to first describe this defensive mutualism, then determined whether human activity directly impacted it. We found that goby behaviour significantly explained variation in shrimp behaviour. Specifically, shrimp varied in how long they remained in their burrow, how long they remained in their burrow after their goby partner(s) emerged, the rate at which they excavated their burrows and the time spent outside their burrows as a function of goby behaviour. Our findings suggest this dynamic mutualism was selectively affected by humans. Human activity, measured by both presence and abundance, explained some variation in multiple goby behaviours that directly influence variation in shrimp behaviour.

人类的存在和城市化改变了许多物种的脆弱性和感知风险，但很少有研究调查人为影响如何影响动态防御性共生体的行为。随着人类活动在海洋生物群落中的不断扩大，了解人类活动如何影响依赖行为的共生体的风险评估非常重要。法属波利尼西亚莫奥里亚的虾虎鱼（Ctenogobiops spp.）和鳄虾（Alpheus spp.）在人类活动区域内形成了一种强制性共生关系。我们量化了虾虎鱼的躲藏时间、飞行起始距离和分配给不同行为的时间，首先描述了这种防御性互惠关系，然后确定人类活动是否直接影响了这种关系。我们发现，虾虎鱼的行为可以很好地解释虾行为的变化。具体来说，虾在洞穴中停留的时间、虾虎伙伴出现后在洞穴中停留的时间、挖掘洞穴的速度以及在洞穴外停留的时间都与虾虎的行为有关。我们的研究结果表明，这种动态互惠关系受到人类的选择性影响。人类活动（从存在和丰度两方面衡量）解释了虾虎鱼多种行为的一些变化，而这些行为会直接影响对虾行为的变化。

Invasive species are a major threat to biodiversity especially because of their influence on native species. Their behaviours, including those in nonsocial contexts, significantly influence species fitness, drive invasion processes and can result in the competitive exclusion of less dominant species. Understanding these behavioural patterns is vital for the protection of native species and the control of invasive species spread. There is still a controversy regarding the success of invasive species, whether it is attributed to inherent behavioural traits or to adaptations to new environments. This study focused on native populations of two sympatric lizard species in Croatia: a lizard known for its invasiveness, Podarcis siculus, and the eastern Adriatic endemic Podarcis melisellensis. We evaluated nonsocial behaviour associated with competition, including food consumption, exploratory behaviour and risk-taking behaviours, using two primary apparatuses: an open field and a radial maze. Podarcis siculus exhibited higher levels of exploratory behaviour, reduced risk-taking behaviours and greater food consumption than P. melisellensis. These behavioural traits are consistent with behaviour observed in invasive populations of P. siculus, suggesting that they may be intrinsic to the species. Our results indicate that a successful invader is more likely to explore and at the same time be more cautious. Research on behavioural traits in native populations sheds light on preadaptive features of invasive species that could characterize a successful invader, highlighting the importance of researching invasive species in their native range.

入侵物种是生物多样性的主要威胁，尤其是因为它们对本地物种的影响。入侵物种的行为（包括非社会环境下的行为）会极大地影响物种的适应性，推动入侵进程，并可能导致优势较弱的物种在竞争中被排斥。了解这些行为模式对于保护本地物种和控制入侵物种扩散至关重要。关于入侵物种的成功，是归因于固有的行为特征，还是归因于对新环境的适应，目前仍存在争议。这项研究的重点是克罗地亚两种同域蜥蜴的原生种群：一种是以入侵性著称的Podarcis siculus蜥蜴，另一种是亚得里亚海东部特有的Podarcis melisellensis蜥蜴。我们使用两种主要装置：空地和径向迷宫，评估了与竞争相关的非社会行为，包括食物消耗、探索行为和冒险行为。与P. melisellensis相比，Podarcis siculus表现出更高水平的探索行为、更少的冒险行为和更多的食物消耗。这些行为特征与在P. siculus入侵种群中观察到的行为一致，表明它们可能是该物种的固有特征。我们的研究结果表明，成功的入侵者更倾向于探索，同时也更加谨慎。对原生种群行为特征的研究揭示了入侵物种的预适应特征，这些特征可能是成功入侵者的特征，突出了在原生地研究入侵物种的重要性。

One of the key decisions made by parents is determining how many offspring to produce using the available resources. This decision is often made in the presence of other individuals that are also attempting to reproduce. Here, we explored the clutch size response of group-reproducing female parasitoids in the bethylid genus Sclerodermus to the presence of their conspecifics prior to oviposition. We removed excess foundresses before oviposition and focused on the subsequent decisions of individual foundresses. We tested two hypotheses regarding the cues that foundresses may use to attune their reproduction. One was that clutch size decisions are adjusted according to the host handling stage at which cofoundress groups form prior to oviposition. We found no support for this hypothesis, possibly because our experimental groups were unnaturally brief. The other was that cofoundresses assess the time they are together with the host prior to oviposition to adjust their clutch size decisions. We found support for this hypothesis via a decline in the size of clutches produced by individual foundresses as the duration of their association with cofoundresses increased. It appears that smaller clutches were laid in anticipation of concurrent reproduction by the associated cofoundresses and to maintain sufficient per capita resources for the development of offspring that will experience scramble competition. This explanation was supported by further findings that larger offspring were produced when the association with cofoundresses was for longer periods. In Sclerodermus, lengthy associations with cofoundresses, both pre- and postoviposition, mean that the clutch size decisions in this study are just part of a wider set of strategic considerations that affect the success of any given foundress and her offspring within the reproductive group.

亲本的关键决策之一是决定利用现有资源生产多少后代。这一决定往往是在其他个体也试图繁殖的情况下做出的。在这里，我们探讨了贝叶虫属（Sclerodermus）中群体繁殖的雌性寄生虫在产卵前对其同种存在的反应。我们在产卵前除去了多余的雌产卵者，并重点研究了个体雌产卵者随后的决定。我们检验了关于雌发现者可能用来调整其繁殖的线索的两个假设。一种假设是，在产卵前，根据寄主处理阶段调整产卵窝的大小。我们没有发现对这一假设的支持，可能是因为我们的实验组时间太短了。另一种假设是，同窝母蝇会评估它们在产卵前与宿主在一起的时间，以调整它们决定的合群数量。我们发现，随着雌性个体与同窝雌性在一起的时间延长，它们所产的窝的大小也在下降，从而支持了这一假设。看来，产下较小的卵是为了预期与之有联系的同窝雌性会同时进行繁殖，并保持足够的人均资源，以培育将经历争夺竞争的后代。进一步的研究结果支持了这一解释，即当与同窝雌虫的结合时间较长时，产生的后代较大。在硬骨鱼类中，无论是在产卵前还是产卵后，与同窝雌性的结合时间都很长，这意味着本研究中的离合器大小决定只是一系列更广泛的战略考虑的一部分，这些战略考虑会影响任何特定的雌性发现者及其后代在生殖群体中的成功。

Open-ended vocal learning in Costa's hummingbird 科斯塔蜂鸟的开放式发声学习

Here we examine whether vocal learning in Costa's hummingbird, Calypte costae, is open-ended. Open-ended learning is the ability of a vocal learning animal to memorize and learn to incorporate new song material into its vocal repertoire after reaching sexual maturity. Open-ended vocal learners are able to learn as adults because they have either a sensitive phase that never closes or a seasonal reopening of the sensitive phase. In prior experiments, we raised 18 individually housed male Costa's hummingbirds in isolation chambers from fledging (day 21 posthatch) until they were approximately 1 year old. During that time, they were tutored and learned song that was individually specific and stable. Here we report what happened when we moved cohorts of eight (in 2017) and six (in 2018) of these ∼1-year-old birds to communal housing in two outdoor aviaries, placing them in physical, visual and acoustic contact with other adult Costa's hummingbirds that sang songs to which each individual had never previously been exposed. The remaining four 1-year-old birds (in 2018) were instead kept in isolation for their second year as a control, then first exposed to each other at 2 years of age. Within 2 months, all of the 1-year-old birds rapidly changed their songs to produce novel songs that were unique to each aviary. The control birds that remained in isolation for a second year did not change their songs. These second-year birds then changed their songs when they were moved to the aviaries and exposed to novel song for the first time at 2 years of age. Although additional experiments are important (e.g. tutoring adults raised in the wild), our results show that Costa's hummingbirds have open-ended vocal learning through at least their third year.

我们在此研究哥斯达黎加蜂鸟（Calypte costae）的发声学习是否具有开放性。开放式学习是指发声学习动物在达到性成熟后记忆并学习将新的歌曲材料纳入其发声曲目的能力。开放式发声学习动物之所以能够在成年后学习，是因为它们的敏感期从不关闭，或者敏感期会随季节重新开放。在之前的实验中，我们将 18 只单独饲养的雄性科斯塔蜂鸟从羽化（孵化后第 21 天）开始在隔离室中饲养到大约 1 岁。在此期间，我们对它们进行了辅导，并让它们学习各自特定且稳定的鸣叫。在此，我们报告了当我们将8只（2017年）和6只（2018年）这些1∼1岁的鸟类移至两个室外鸟舍的群居环境中，让它们与其他成年科斯塔蜂鸟在身体、视觉和听觉上接触时发生的情况，这些成年科斯塔蜂鸟所唱的歌曲是每个个体以前从未接触过的。其余四只 1 岁的鸟儿（2018 年）则在第二年作为对照被隔离饲养，然后在 2 岁时首次相互接触。在 2 个月内，所有 1 岁大的鸟都迅速改变了它们的歌声，发出了每个鸟舍独有的新歌声。而第二年仍处于隔离状态的对照组鸟类则没有改变它们的歌声。当这些第二年的鸟被转移到鸟舍，并在 2 岁时第一次接触到新歌声时，它们的歌声也发生了变化。虽然更多的实验很重要（例如，对野外饲养的成鸟进行辅导），但我们的研究结果表明，科斯塔蜂鸟至少在第三年可以进行开放式的声音学习。
