The lesser kestrel Falco naumanni is a facultative colonial falconiform whose breeding range stretches across the entire Palaearctic. As with other pseudo-steppe birds, the lesser kestrel has experienced a sharp decline in western Europe over the last decades, spurring conservation actions. We compared natal philopatry of captive versus wild-bred individuals and the effect of release date on philopatry by comparing return data of captive- and wild-bred kestrels from 13 colonies between 2004 and 2019. We found that wild-bred kestrels show significantly stronger philopatry than their captive-bred counterparts, possibly due to the lack of parental influence experienced by the latter during their first days. No relationship was detected between release date and natal philopatry. Future studies should focus on factors affecting the philopatric behaviour of lesser kestrels bred in captivity, which could in turn improve their captive breeding and release strategy.

Deforestation for land-use change in Borneo has global impacts on biodiversity. Mixed-use landscapes are spatially integrative countermeasures to conserve critical forest habitats for wildlife along with economic development. We used camera-traps to inventory remnant mammalian diversity, species richness, detection counts, and diel activity functions in protected forest areas in a large oil palm plantation landscape in East Kalimantan, Bornean Indonesia. From among 2,286 independent detections of species, our results provide evidence of the presence of at least 33 mammals in these forest areas, including species of high conservation value such as the critically endangered Bornean orangutan Pongo pygmaeus and the Sunda pangolin Manis javanica. Additionally, we provide diel activity patterns for 14 of the detected species and reflect on their meaning in the context of their habitat. Due to plantation activities, the protected areas may underlie characteristic ecological dynamics with an impoverished large carnivore guild and a majority of small mammals and small carnivores interacting as predator and prey. Abundant oil palm crops likely benefit large populations of small mammals (highest detection counts) while simultaneously supplying resources for a diverse carnivore community (highest species-richness) preying on small mammals. We highlight the potential of the forested protected areas as wildlife refugia in mixed-use landscapes for conservation and production efforts. We recommend further monitoring to ensure fulfilling this potential in the continuous management.

The genus Characidium has the highest species richness within the Crenuchidae family and the Characidiinae subfamily. Characidium pterostictum holds immense importance due to its widespread distribution in South America, especially in the hydrographic systems of the Uruguay River. The objective of this study is to describe the feeding biology of Characidium pterostictum in streams of the Ijuí River basin (Uruguay River system) in southern Brazil and to identify potential spatial and ontogenetic variations in its diet. Samples were collected from three tributaries of the Ijuí River. Food items were identified and quantified using the volumetric method and frequency of occurrence. Characidium terostictum was characterized as an insectivorous fish, a specialization previously reported in Characidiinae. There was a slight difference in feeding patterns based on variations in standard length and sampling sites. Ontogenetic analysis showed that C. pterostictum expands its feeding spectrum as it develops. The consumption of autochthonous items such as insect remains (Ephemeroptera, Trichoptera, and Chironomidae) as the primary component of diet indicates that this fish species requires extensive preservation of the watercourses it inhabits.

Predicting the future abundance and distribution of introduced alien species is crucial to mitigate their impact on ecosystems, but this has been shown to be highly challenging. A good approach to obtain crucial clues to the root causes behind dynamic changes over time and space of invasive species is historical resurveys. Barcelona holds one of the largest densities in Europe of monk parakeets Myiopsitta monachus, a highly successful invasive avian alien species. In this study, we evaluate population size, population growth rates and range expansion across the city, performing periodic nest and chamber counts from detection of the first nest in 1976 to 2022. Population estimates of monk parakeets during the study period showed a steady increase, reaching 6,444 ± 449 individuals in 2022. The population exhibited exponential growth with a mean population growth rate of r = 0.19 per year, which means a population doubling time of 3.7 years. Furthermore, two phases were evident: the first from 1976 to 1994 with a growth rate of 0.37 and a population doubling time of 1.9 years; and the second from 1999 to 2022 with a growth rate of 0.08 and a time to double the population of nine years. Moreover, we document the expansion of the range during our study through the colonisation of new areas, which fitted to a diffusion model for the whole period. Currently, the growth rate of the invasive monk parakeet population does not appear to be limited by resources, nest availability, disease, or predators and we expect them to continue increasing and expanding their range if no control measures are taken.

We studied the distribution of bird and bat species richness in Sierra de Guadarrama (Spain). We observed that bird richness had the highest scores at mid-elevations while bat richness increased monotonically with altitude. Both bird and bat richness were positively related to primary productivity but decreased and increased respectively with woodland cover. In addition, birds tracked vegetation complexity and shrub richness while bats did not track these fine-grained habitat traits. These differences could be related to the spatial scale of habitat use by birds and bats. While birds occur in small home ranges, bats can fly many km away from breeding sites in search of food. The tracking by bats of productive areas would thus blur the effect of fine-grained habitat traits. Our results suggest the need for further research on how the changes observed in productivity and tree cover in these mountains could affect distribution of bird and bat richness.

Jaguars are the apex predators of tropical and subtropical ecosystems in the Americas but their conservation is threatened due to habitat loss, poaching, and conflicts over predation. The Northern Jaguar Reserve (NJR) was created by Naturalia A.C. as a project to protect the northernmost jaguar population within an area of 59.3 thousand acres (24.4 ha) of private property. The property also includes other protected species. The present study was conducted to verify the status of this jaguar population in order to evaluate the effectiveness of the NJR, and to contribute to knowledge regarding its ecology. We estimated density using mark-resight and spatially explicit capture-recapture (SERC) models, and evaluated home range through a survey with 56 camera-trap stations over 12 bimonthly periods. In total, we obtained a sampling effort of 40,880 camera-days, registering 2.32 records from 1,000 camera-days. Jaguar density, calculated using the capture-recapture models, ranged from 0.3 to 1.44 indiv./100 km2, while the SERC model estimated a density of between 0.21 and 3.04 indiv./100 km2. The home range was 78.9 km2 for males and 45.1 km2 for females. Long-term population monitoring together with the establishment of Areas Voluntarily Assigned to Conservation, an initiative recently created by the Mexican government, such as the NJR, could be a valid strategy to strengthen jaguar conservation and thereby maintain key ecological processes for other species and their habitat in northwestern Mexico.

Worldwide, forests are considered biodiversity hotspots. Butterflies are among the surrogate species for forest biodiversity yet in many parts of the world, little is known about the presence or habitat use of forest-dweller butterflies. In this study we aimed to narrow the information gap by applying a time-effective butterfly survey in forests in northeast Türkiye that are surrounded by several prime butterfly areas. The target species were Boloria euphrosyne, Coenonympha arcania, Erebia aethiops, and Satyrium ilicis. The surveys provided 128 records of the species. Random forests models showed that the mean temperature of the warmest month, canopy cover of pine trees, tree size, and managed meadows in or at the edge of forests are important parameters for species occurrence. Nevertheless, the direction of the effects varied between species. Maintaining heterogeneity in forests in terms of the forest variables indicated above and promoting small-scale grassland management in forest openings and edges are important conservation measures for forest-dwelling butterflies. The relevance of the temperature suggests that climate change may have significant effects on the occurrence of forest butterflies. Key words: Habitat use, Hay meadows, Forest structure, Erebia aethiops, Satyrium ilicis, Coenonympha arcania

Sexual selection is one of the main causes of the diversity of reproductive behaviours observed intra- and interspecifically. Here we study the reproductive behaviour of a unique species, Phylolestes ethelae, the only member of the family Synlestidae (Odonata) found in America. Our hypothesis was that the phylogenetic uniqueness of this species and the fact that it lives on an island would produce novel behaviours worth protecting as they are a part of the biodiversity. Between 2017 and 2019 we studied a population of P. ethelae in the National Park Armando Bermúdez in the Dominican Republic by means of mark-recapture techniques and focal observations. The survival rate was estimated as 0.953 ± 0.012 (SE), which translates into an expected lifespan of 20.6 days. We found that some males showed high site fidelity but very little activity, and territorial disputes were almost inexistent. Females, on the other hand, were rarely observed on the river, and were found mainly on the nearby paths and forest. We recorded 28 tandems and observed a total of 17 copulations, lasting an average of 18.6 min. Examination of sperm volumes in females interrupted during copulation indicated that males removed most of the sperm from the female bursa copulatrix during stage I of copula, but they could not remove sperm from the paired spermathecae. The duration of precopulatory tandem was highly variable (from 3 min to 7.8 h). In some cases, copulation was observed shortly (3 min) after tandem formation, mainly during the morning. However, some pairs formed during the morning, remained in tandem for several hours, and mated late, after dusk. Females laid eggs not accompanied by the male. Mating after the main peak of activity might be a strategy which protects sperm investment because females laying eggs after dusk are unlikely to be mated again that day. Further studies are needed to decipher phenotypic correlates of the males that mate after dusk.

Examination of sperm volumes in females interrupted during copulation indicated that males removed most of the sperm from the female bursa copulatrix during stage I of copula, but they could not remove sperm from the paired spermathecae. The duration of precopulatory tandem was highly variable (from 3 min to 7.8 h). In some cases, copulation was observed shortly (3 min) after tandem formation, mainly during the morning. However, some pairs formed during the morning, remained in tandem for several hours, and mated late, after dusk. Females laid eggs not accompanied by the male. Mating after the main peak of activity might be a strategy which protects sperm investment because females laying eggs after dusk are unlikely to be mated again that day. Further studies are needed to decipher phenotypic correlates of the males that mate after dusk.","PeriodicalId":49107,"journal":{"name":"Animal Biodiversity and Conservation","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140485058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Colonial birds often breed at high density, generating conflict among neighbours over the use of nest-building materials. However, in a few colonial species, breeders appear to cooperate in the construction of compound nests that contain multiple breeding chambers within a single nest structure. The relative contributions of individual birds and the balance between cooperation and conflict among close neighbours in such species have rarely been examined. In this study, we investigated evidence for cooperation and conflict in the building and maintenance of the nests of monk parakeets Myiopsitta monachus in an invasive population in which compound nests are frequent. First, we found that males invested more in nest construction than females and when more than one male occupied the same breeding chamber multiple males contributed to the same nest. Females, by contrast, invested more in nest defence than males. Second, we found that there was conflict among pairs over nest material, with kleptoparasitism of nesting material and defence against conspecifics evident. We conclude that nest-building in monk parakeets involves both cooperation and conflict. Breeders often tolerate the budding of nests, which are often built by relatives, but that pairs are also in conflict over the use of nest material.
