The optimized nutrient exchange between partnered species can govern the stability of mutualisms; however, the underlying regulatory mechanisms are often poorly understood. In this study, these mechanisms were explored in obligate mutualisms between leafcutter ants, Atta and Acromyrmex, and the fungus, Leucoagaricus gongylophorus, they provision with plant fragments. The fungus concentrates nutrients inside swollen hyphal cells called gongylidia, which are consumed by ants. Compared with the well-studied mechanisms of resilient cultivar production by ants, little is known about whether and how the fungal cultivar regulates stable nutritional yield. Here, we initially isolated the fungus from ant farmers and then showed that gongylidia had variable levels of carbon storage glycogen when cultured in vitro on different carbon sources. Next, we tested whether leafcutter ants regulate their cultivar's nutritional yield when actively farming their crop. Results showed that fungal glycogen remained stable but with a low total glycogen yield when farmed by lab-maintained leafcutter colonies confined to a nutritionally imbalanced forage material. In addition, similar fungal glycogen stability with a low total yield was observed across three leafcutter species with different farming systems when foraging for plant materials containing diverse carbohydrates. Although the cultivar's nutritional yield can vary with provisioned nutrients, ant farmers thus appear to suppress this variation through their farming behaviours. Conducting further experiments is recommended to explore the mechanisms by which symbiotic nutrient exchange can be fine-tuned by the ants in response to the specific nutritional needs of the colony and the mechanisms by which the fungus crop signals its nutritional needs to ant farmers.

配偶种间最佳的养分交换控制着共生关系的稳定性；然而，人们对潜在的调控机制往往知之甚少。本研究探讨了切叶蚁Atta和Acromyrmex与提供植物片段的真菌Leucoagaricus gongylophorus之间的专性共生机制。这种真菌将营养物质集中在肿胀的菌丝细胞中，这些菌丝细胞被蚂蚁吃掉。与蚂蚁抗逆性品种生产机制相比，真菌品种是否以及如何调节稳定的营养产量尚不清楚。在这里，我们首先从蚁农中分离出真菌，然后证明在不同碳源的体外培养下，巩膜菌具有不同水平的碳储存糖原。接下来，我们测试了切叶蚁在积极种植作物时是否会调节其品种的营养产量。结果表明，在营养不平衡的饲料条件下，真菌糖原保持稳定，但总糖原产量较低。此外，在不同的耕作制度下，三种切叶植物在觅食含有不同碳水化合物的植物材料时，观察到相似的真菌糖原稳定性和低总产量。尽管该品种的营养产量可能随所提供的营养而变化，但蚁农似乎通过其耕作行为抑制了这种变化。建议进行进一步的实验，以探索蚂蚁根据群体的特定营养需求微调共生营养交换的机制，以及真菌作物向蚁农发出营养需求信号的机制。

Lion prides consist of related females, their offspring and a coalition of adult males that has entered from elsewhere. Female matrilines usually persist for generations whereas coalitions only persist for a single generation. Female territoriality focuses on key landscape features that enhance access to prey, water and denning sites, while male defence of that space is primarily driven by maintaining exclusive access to those females. Both sexes show fission–fusion grouping patterns but remain in contact with each other by long-distance vocalizations. Female sociality in lions derives from their relatively high population abundance combined with the heterogeneity of savannah habitat compared to the lower population abundance and homogeneous forested habitat found in other large felids. Male lions form coalitions because of the synchronous breeding of females that results from the infanticidal behaviour of incoming coalitions.

狮群由亲缘关系密切的雌狮、它们的后代以及从其他地方进入的成年雄狮组成。母系通常会持续几代人，而联盟只会持续一代人。雌性的领地性主要集中在关键的景观特征上，这些特征可以增加获得猎物、水和洞穴的机会，而雄性对该空间的防御主要是通过保持对这些雌性的专属通道来驱动的。两性都表现出分裂融合的群体模式，但通过远距离发声保持联系。狮子的雌性社会性来源于它们相对较高的种群丰度和草原栖息地的异质性，而其他大型猫科动物的种群丰度较低，森林栖息地也较均匀。雄狮结成联盟是因为雌狮的同步繁殖，这是由即将到来的联盟的杀婴行为造成的。

Societies are more than groups of animals coexisting; they are structured, enduring communities defined by stable membership, shared identity and relationships that persist across generations. Among mammals, such societies are uncommon but reach their most extreme form in the eusocial African mole-rats, namely the naked mole-rat, Heterocephalus glaber, and the Damaraland mole-rat, Fukomys damarensis. Eusociality, well known from ants, bees and termites, is a social system loosely comparable to a monarchy, in which a single breeding queen and one or a few males monopolize the colony's reproduction, while other group members suppress their own reproductive potential to serve the needs of the colony. These mole-rats are among the only mammals to fully embody this system, forming long-lived, cooperative colonies with strict boundaries between colony members and outsiders. Yet their strategies for social cohesion diverge. Fukomys damarensis depends primarily on individual familiarity to maintain group identity, thereby limiting colony size. In contrast, H. glaber uses a shared colony scent and distinct colony-specific vocal dialect to support larger, scalable societies. By comparing these societal extremes, this review explores what makes societies stable, exclusive and resilient, while highlighting the gaps in our current knowledge.

社会不仅仅是一群动物共存；他们是有组织的、持久的社区，由稳定的成员、共同的身份和代代相传的关系所定义。在哺乳动物中，这样的社会并不常见，但在真正群居的非洲鼹鼠，即裸鼹鼠（Heterocephalus glaber）和达马拉兰鼹鼠（Fukomys damarensis）中达到了最极端的形式。从蚂蚁、蜜蜂和白蚁身上我们都知道，群居性是一种与君主制大致相当的社会制度，在这种制度下，一个繁殖的女王和一个或几个雄性垄断了群体的繁殖，而其他群体成员则抑制自己的繁殖潜力，以满足群体的需求。这些鼹鼠是唯一完全体现这一体系的哺乳动物，它们形成了长寿、合作的群体，在群体成员和外部群体之间有严格的界限。然而，他们在社会凝聚力方面的策略存在分歧。damarensis主要依靠个体的熟悉度来维持群体身份，从而限制了群体的大小。相比之下，H. glaber使用共同的群体气味和独特的群体特有的声音方言来支持更大、可扩展的社会。通过比较这些社会极端，本综述探讨了是什么使社会稳定、排外和有弹性，同时强调了我们目前知识的差距。

Eavesdropping on acoustic signals plays a crucial role in decision making for many animals. While much research has focused on how bats use sound for orientation and foraging, surprisingly little has focused on how eavesdropping impacts survival and decision making. We examined how four insectivorous bat species in North America, the big brown bat, Eptesicus fuscus, silver-haired bat, Lasionycteris noctivagans, hoary bat, Lasiurus cinereus, and little brown bat, Myotis lucifugus, respond to conspecific and heterospecific call sequences. Between June and August of 2023, we played distress and aerial hawking attack sequences along Battle Creek in southwest Saskatchewan, Canada, and used acoustic recorders to measure any changes in bat activity during and just after the playbacks. We hypothesized that bat activity would increase in response to both conspecific and heterospecific call sequences, with species-specific differences based on size and life history. However, we found that while L. cinereus were attracted to conspecific hawking sequences (= feeding buzzes), they were not attracted to any other conspecific or heterospecific attack or distress sequences. Lasionycteris noctivagans, in turn, were repelled by L. cinereus hawking sequences but did not respond to conspecific or heterospecific distress calls. Myotis lucifugus did not respond to conspecific or heterospecific distress call or hawking attack sequences. This is in contrast with previous studies that have concluded M. lucifugus is attracted to conspecific vocalizations. Our findings underscore our limited understanding of how bats respond to call sequences and, more generally, bat community relationships.

对许多动物来说，窃听声音信号在决策中起着至关重要的作用。虽然很多研究都集中在蝙蝠如何利用声音来定位和觅食，但令人惊讶的是，很少有人关注窃听如何影响生存和决策。研究了北美洲大褐蝠（Eptesicus fuscus）、银毛蝠（silver-haired bat）、Lasionycteris noctivagans)、灰蝠（Lasiurus cinereus）和小褐蝠（Myotis lucifugus）对同种和异种鸣叫序列的响应。在2023年6月至8月期间，我们在加拿大萨斯喀彻温省西南部的巴特克里克播放了遇难和空中鸣叫攻击的序列，并使用声学记录器来测量回放期间和之后蝙蝠活动的任何变化。我们假设蝙蝠的活动会增加对同种和异种呼叫序列的响应，并根据大小和生活史存在物种特异性差异。然而，我们发现，当L. cinereus被同种叫卖声序列（=摄食蜂鸣声）吸引时，它们不会被任何其他同种或异种的攻击或痛苦序列吸引。而夜蛾则被L. cinereus hawking序列击退，但对同种或异种的求救信号没有反应。lucitis对同种或异种的求救信号或霍金攻击序列没有反应。这与之前的研究结果相反，之前的研究得出结论，M. lucifugus被同种发声所吸引。我们的发现强调了我们对蝙蝠如何响应呼叫序列以及更普遍的蝙蝠群落关系的有限理解。

Emotional contexts influence vocal individuality in ungulates 情感环境影响有蹄类动物的声音个性

For group-living animals, such as most ungulates, the ability to recognize members of one's social group is crucial. While vocalizations often carry cues to identity, they are also affected by the affective state of the caller, and signals often become more chaotic in contexts of negative valence or high arousal. How does this influence vocal individuality, and is there a pattern across taxa? In order to understand how the individual information content is maintained in emotionally charged contexts, we studied contact calls that were positive or negative in valence in seven ungulate species (cattle, goats, sheep, pigs, wild boars, horses and Przewalski's horses). The information content of these calls was assessed using (1) Beecher's information statistic and (2) the potential of individuality coding (PIC). Across species, calls produced in negative-valence contexts contained less individual information than those in positive-valence contexts. Nevertheless, each species exhibited at least one acoustic parameter that reliably signalled individuality across emotional states. Our findings indicate that negative valence overrides individual information in ungulate vocalizations at least to some extent, and imply that individual vocal recognition may require acoustic stability in certain important parameters, which vary depending on the species. These findings reveal a nuanced role of affective communication and show how emotional expression interacts with the informational content of vocal signals used to maintain social bonds among socially complex animals.

对于群居动物来说，比如大多数有蹄类动物，识别社会群体成员的能力至关重要。虽然声音通常带有身份线索，但它们也受到呼叫者情感状态的影响，并且在负价或高唤醒的情况下，信号往往变得更加混乱。这是如何影响声音的个性的，在不同的分类群中是否存在一种模式？为了理解个体信息内容是如何在充满情感的环境中保持的，我们研究了七种有蹄类动物（牛、山羊、绵羊、猪、野猪、马和普氏野马）的正价或负价接触呼叫。利用比彻信息统计和个性编码潜能（PIC）对这些呼叫的信息含量进行评估。跨物种，在负价环境下产生的呼叫比在正价环境下产生的呼叫包含更少的个体信息。然而，每个物种都表现出至少一个声学参数，可以可靠地表明情绪状态下的个性。我们的研究结果表明，在有蹄类动物的发声中，负效价至少在一定程度上覆盖了个体信息，这意味着个体的声音识别可能需要某些重要参数的声学稳定性，这些参数因物种而异。这些发现揭示了情感交流的微妙作用，并展示了情感表达如何与声音信号的信息内容相互作用，这些声音信号用于维持社交复杂动物之间的社会联系。

Habitat and shelter selection are critical behavioural processes influencing survival, growth and fitness across animal taxa. Understanding these processes provides key insights into how animals interact with their environment, respond to risks and maximize fitness. In benthic marine species, early life stages often face intense predation risk, making the choice of an appropriate refuge especially relevant. We investigated shelter-seeking behaviour in early benthic phase European lobster, Homarus gammarus, under controlled laboratory conditions, testing individuals in isolation to examine intrinsic shelter selection patterns without social interactions. Naïve stage VI juveniles were presented with mussel shell aggregations, stones representing natural cobble habitats and artificial polyvinyl chloride pipes as potential refuges. Initial shelter selection showed no significant deviation from random distribution, but extended observation periods revealed distinct temporal patterns in shelter use. Although juveniles readily occupied available shelters, monitoring after initial selection showed shelter-switching behaviour, particularly overnight, with transitions predominantly towards mussel shell aggregations. Across repeated trials, shelter-seeking efficiency improved, with decreased exploration times and reduced exploratory behaviours. Mussel shells emerged as the preferred shelter type, showing the highest retention rates and receiving the most transitions from other shelter types. This refinement in shelter selection suggests an innate preference for structurally complex refuges during the early benthic phase. These findings provide insights for optimizing restoration strategies, particularly in the context of restorative aquaculture where mussel farming areas could provide suitable release habitats. However, field validation remains essential for understanding how these behaviours translate to naturalconditions where predation pressure would influence shelter-seeking strategies.

栖息地和庇护所的选择是影响动物类群生存、生长和适应性的关键行为过程。了解这些过程可以帮助我们了解动物如何与环境相互作用，如何应对风险并最大限度地提高健康水平。在底栖海洋物种中，生命的早期阶段往往面临着强烈的捕食风险，因此选择合适的避难所尤为重要。我们在受控的实验室条件下，研究了欧洲龙虾Homarus gammarus的早期底栖期寻求避难所的行为，测试了个体在没有社会互动的情况下的内在避难所选择模式。Naïve六期幼鱼呈现贻贝聚集体，代表天然鹅卵石栖息地的石头和人工聚氯乙烯管作为潜在的避难所。最初的庇护所选择与随机分布没有明显的偏差，但延长的观察期揭示了庇护所使用的不同时间模式。虽然幼鱼很容易占据可用的庇护所，但在初步选择后的监测显示，它们有转换庇护所的行为，特别是在夜间，主要是向贻贝聚集的方向过渡。经过反复试验，寻找掩体的效率提高了，勘探时间减少了，勘探行为也减少了。贻贝壳成为首选的庇护所类型，显示出最高的保留率，并从其他庇护所类型接收最多的过渡。这种庇护所选择的改进表明，在底栖动物早期阶段，对结构复杂的避难所有先天的偏好。这些发现为优化恢复策略提供了见解，特别是在恢复性水产养殖的背景下，贻贝养殖区可以提供合适的放生栖息地。然而，实地验证对于理解这些行为如何转化为捕食压力会影响寻求庇护策略的自然条件仍然至关重要。
