Color mutations are a common phenomenon in vertebrates. Among these anomalies, albinism is the most common in wild mammals. We deployed 78 camera traps across the Yoko Council Forest (YCF) to inventory medium to large-sized terrestrial mammals and we obtained a total effort of 17,981 operational camera trap days, giving 169 detections of long-nosed mongoose. During this study, we obtained two independent detections of albino long-nosed mongooses (Xenogale naso). To our knowledge, this is the first report of albinism in this taxon.
肤色突变是脊椎动物的一种常见现象。其中，白化病在野生哺乳动物中最为常见。我们在横沟议会森林（Yoko Council Forest，YCF）部署了78个相机陷阱，以清点中型至大型陆生哺乳动物，我们共获得了17981个相机陷阱工作天数，发现了169只长鼻獴。在这项研究中，我们发现了两只白化长鼻獴（Xenogale naso）。据我们所知，这是该分类群中首次发现白化现象。

The crab-eating fox Cerdocyon thous is one of South America’s most common species of canids; its generalist habits and plasticity allowed the species to adapt to numerous habitats and human presence. In 2020, we registered a specimen of C. thous on a trap camera placed in the vicinity of the Huaco River in La Rioja Province, Argentina. This record was the starting point for evaluating past and present environmental niche models (ENMs) of the species throughout their entire distribution in South America. ENMs models suggest that the presence of C. thous in La Rioja has low suitability values and suggest that we may be facing a sink population scenario due to the low frequency of records in the province. Also, the model indicated that the parameters delimiting the areas with the highest suitability values are related to temperature, isothermality, and precipitation. Long-term studies in the region are needed to determine the population dynamics of C. thous in La Rioja.

Chromatic disorders in bats are typically documented by brief, incidental observations of individuals at day roosts or by accidental captures during mist-netting. Such descriptions usually lack observations on social behaviour including interactions between bats with aberrant pigmentation and other individuals. Here, we report the first observation of leucism in the greater sac-winged bat Saccopteryx bilineata. Over the course of six weeks, we were able to follow the development of a wild pup with a conspicuous aberrant pigmentation, by observing it in its day roost. Our observations indicate that the vocal and behavioural development of the pup was entirely normal, as well as the integration into its social group. After six weeks, when the pup was already foraging individually, it did not return to its colony in the morning, indicating that it may have been preyed on.

In 1750 Pierre Poivre donated the holotype of the douc monkey Pygathrix nemaeus to R.-A. F. de Réaumur. Its type locality is here restricted from “Cochinchine” to near Da Nang, Vietnam. In 1757, Buffon appropriated the holotype for the King’s collection, wrongly inferring that the species lacks ischial callosities, and conflating it with the sifaka of Madagascar. “D’ouc” is evidently a corruption of Voọc, the Vietnamese word for colobine monkey. In 1819, a French crew shot 100 doucs before breakfast on a mountain near Da Nang. In 2016, the whole mountain population was estimated at 70. By 1831 doucs had learnt to fear gunfire, but locals accepted their proximity, and provided some protection from meat-seeking foreigners. Several doucs were collected for museums in the 19th and 20th century; in 1897 two even lived for a fortnight at the Jardin des Plantes, Paris. The douc was observed and collected near Da Nang during its miraculous survival of the Vietnam War; its evergreen forest habitat surprisingly resilient. This situation is rapidly deteriorating, as forests are reduced to isolated pockets, and hunting prohibitions unenforced. The closely-monitored Mount Son Tra douc population was expanding, but tourist development is illegally eroding the Nature Reserve.

Kinkajous are one of the most widely distributed Neotropical mammals, nonetheless, their nocturnal habits have posed challenges on the study of their ecology and behavior. Here, we used arboreal camera trapping in a pristine Amazonian forest in Ecuador, and ad libitum data from direct encounters in a lowland and a highland forest in Colombia to describe their activity patterns and describe anecdotal data on their diet and reproductive behaviors. As expected, kinkajous are strictly nocturnal and seem to be active throughout the entire night, although in our study there was less activity towards the beginning and the end of the night. Kinkajous were observed to be mostly solitary, rarely in groups of two to three adult individuals. Although their diet has not been described in detail, fruits from Moraceae and Urticaceae appear to be important components of their diet. Their reproductive behavior involves an isolated pair of kinkajous, and may be interrupted by other males. Pairs seem to meet for reproductive purposes and range together for several hours, during which courtship may take place, ending in copulation, which lasts for approximately 3 min. After copulation, the male and female appear to separate and return to their solitary habits. The results of this study complement the scarce information on the elusive kinkajous in the Neotropical forests.

We investigated the breeding activity of three sympatric rodent species: Stenocephalemys albipes, Mastomys awashensis, and Acomys cahirinus, in the semi-arid region of Tigray in northern Ethiopia, using mark-recapture data, to determine the influence of rainfall on their breeding patterns within exclosure (i.e., protected area from livestock grazing). Breeding activities of S. albipes and M. awashensis commenced during the wet season, continued into the early dry season, and ceased during the subsequent dry season. The proportion of breeding females reached its peak during the wet season, gradually declining until the dry season. In contrast, A. cahirinus exhibited a different breeding strategy, with year-round breeding, including during the dry season, a period characterized by limited resources. A significant difference in the proportion of breeding females among the three species was observed across seasons. Furthermore, all species shared a common trend of heightened breeding activity, particularly at the conclusion of the wet season and the onset of the early dry season. These findings enhance our understanding of the interplay between rainfall and seasonal breeding within exclosures, while other variables remain constant. Moreover, the region’s future plans for managing rodents and the establishment of exclosures must take this information into account.
我们调查了三种同域啮齿动物的繁殖活动：在埃塞俄比亚北部提格雷半干旱地区，我们利用标记重捕数据研究了Stenocephalemys albipes、Mastomys awashensis和Acomys cahirinus的繁殖活动，以确定降雨对它们在围栏（即免受牲畜放牧的保护区）内繁殖模式的影响。S. albipes 和 M. awashensis 的繁殖活动从雨季开始，一直持续到旱季初期，并在随后的旱季停止。雌性繁殖比例在雨季达到高峰，之后逐渐下降，直至旱季。相比之下，A. cahirinus表现出不同的繁殖策略，全年都在繁殖，包括在资源有限的旱季。三个物种的繁殖雌性比例在不同季节存在显著差异。此外，所有物种都有一个共同的趋势，即繁殖活动加剧，尤其是在雨季结束和旱季开始初期。这些发现加深了我们对在其他变量保持不变的情况下，降雨与围栏内季节性繁殖之间相互作用的理解。此外，该地区未来的啮齿动物管理计划和隔离区的建立必须考虑到这些信息。

The southern distribution of Micronycteris sanborni became controversial after the description of Micronycteris yatesi based on specimens formerly reported as M. sanborni in Bolivia. It raised doubts on the identity of the southernmost specimen of M. sanborni reported from Serra da Bodoquena, Brazil. We rechecked the identification of this specimen and report four new records of M. sanborni from Serra da Bodoquena. External and craniodental features of all five examined specimens fit the current M. sanborni diagnosis, supporting this region as the southern boundary of its geographic range in South America.

The Andean white ear opossum (Didelphis pernigra, Allen 1900) is one of the three species of the genus Didelphis reported in Colombia. Here we present a systematic review of D. pernigra in Colombia, with a geographical and altitudinal distribution hypothesis from the country. We reported geographic records and scientific available information of D. pernigra in 40 studies, 55.26 % of the available literature corresponded to local and regional inventories; 23.68 % of other documents were studies about mammal assemblages, while 21.05 % were specific studies about the species and the genus Didelphis in Colombia. We classified literature according to the following subcategories: natural history, diet, inventories, threats, reproduction, uses and perceptions. Most of the literature corresponded to detection in inventories (55.26 %), followed by natural history information (21.05 %) and threats (7.89 %). Research about diet, uses, perception and reproduction, had the lowest proportion with 5.26 %. Regarding distribution, geographic records ranged between 1060 and 3740 m across the three Andean ranges of Colombia. In general, little is known about the ecology or natural history of the species, efforts should be focused on filling the information gaps about natural history, and surveys should fill the distribution gaps along the Western and Central ranges of Colombia.
安第斯白耳负鼠（Didelphis pernigra, Allen 1900）是哥伦比亚报告的三个白耳负鼠属物种之一。在此，我们对哥伦比亚的 D. pernigra 进行了系统回顾，并提出了该国的地理和海拔分布假设。我们报告了40项研究中关于D. pernigra的地理记录和科学信息，其中55.26%的文献与地方和区域清单相对应；23.68%的其他文献是关于哺乳动物群落的研究，21.05%是关于哥伦比亚Didelphis种和属的具体研究。我们按照以下子类别对文献进行了分类：自然史、饮食、清单、威胁、繁殖、用途和认知。大多数文献都与物种清单中的发现有关（55.26%），其次是自然史信息（21.05%）和威胁（7.89%）。有关饮食、用途、认知和繁殖的研究比例最低，仅占 5.26%。在分布方面，哥伦比亚三个安第斯山脉的地理记录介于 1060 米和 3740 米之间。总体而言，人们对该物种的生态学或自然史知之甚少，因此应集中精力填补自然史方面的信息空白，并通过调查填补哥伦比亚西部和中部地区的分布空白。

Tonatia bidens is listed as ‘Data Deficient’ in the IUCN Red List. Our research, conducted in the Brazilian Caatinga dry forest between 2016 and 2022, aimed to shed light on the diet of this little-known species. Thirty-eight taxa were identified among insect remains beneath T. bidens’ feeding perch. Notably, certain insects such as hawkmoths and cerambycid beetles are agricultural pests with significant negative impacts on crops, including cassava, corn, tomato, papaya, and cashew plantations. These results underscore bats’ crucial role in insect pest consumption, emphasizing the need for further studies to fully understand their diet and ecosystem contributions.

Invasive mammalian predators are arguably the most damaging group of alien animals for global biodiversity and their impacts are particularly damaging in endemic-rich insular ecosystems. Ferrets (Mustela furo) are well-known for their potential to establish self-sustaining feral populations. Yet, knowledge about their distribution and trophic interactions is scarce. Here, we provide ample evidence of a well-established and widespread population of ferrets on the subtropical island of Madeira (Portugal). Ferrets are using natural and human-dominated habitats, where they are preying on both native (e.g., Cory’s shearwaters (Calonectris borealis) and the endemic and IUCN Endangered Zino’s petrel (Pterodroma madeira)) and non-native vertebrates.
