Làm sạch kho hạt giống của cây bách phương tây bởi các động vật gặm nhấm phân thủy, thay đổi theo loại vi mô và loại tán Dịch bởi AI
Integrative Zoology - Tập 17 Số 2 - Trang 192-205 - 2022
**Mô tả** Các loài gặm nhấm phân thủy lưu trữ hạt giống khắp nơi trong khu vực hoạt động của chúng trong những hầm chứa nông cạn trên bề mặt, khác với những hạt giống dự trữ sâu trong hang ổ, rất khó bảo vệ. Các hạt giống đã được chôn thường bị trộm cắp bởi các loài gặm nhấm khác và hoặc được tái chôn, ăn hoặc đưa vào kho dự trữ. Những chuyển động của hạt giống như vậy có thể ảnh hưởng đến quá t...... hiện toàn bộ

Distinctive diet‐tissue isotopic discrimination factors derived from the exclusive bamboo‐eating giant pandaAbstract Stable isotope analysis is very useful in animal ecology, especially in diet reconstruction and trophic studies. Differences in isotope ratios between consumers and their diet, termed discrimination factors, are essential for studies of stable isotope ecology and are species‐specific and tissue‐specific. Given the specialized bamboo diet and clear foraging ... ... hiện toàn bộ

Anthropogenic pressures increase extinction risk of an isolated Asian elephant (Elephas maximus) population in southwestern China, as revealed by a combination of molecular‐ and landscape‐scale approachesAbstract Identification of the effect of anthropogenic threats on ecosystem is crucial. We used molecular tools and remote sensing to evaluate the population status of an isolated Asian elephant population in southwestern China in response to changes in habitat suitability between 1989 and 2019. A total of 22 unique genotypes were identified from 117 dung samples co... ... hiện toàn bộ

Seed size affects rodent–seed interaction consistently across plant species but not within species: evidence from a seed tracking experiment of 41 tree speciesAbstract Scatter‐hoarding rodents play a crucial role in seed survival and seed dispersal. As one of the most important seed traits, seed size and its effect on rodent–seed interaction attract lots of attention. Current studies usually target one or a few species and show inconsistent patterns; however, few experiments include a large number of species although many... ... hiện toàn bộ

Sagittal crest morphology decoupled from relative bite performance in Pleistocene tapirs (Perissodactyla: Tapiridae)Abstract Bite force is often associated with specific morphological features, such as sagittal crests. The presence of a pronounced sagittal crest in some tapirs (Perissodactyla: Tapiridae) was recently shown to be negatively correlated with hard‐object feeding, in contrast with similar cranial structures in carnivorans. The aim of this study was to investigate bite... ... hiện toàn bộ

Sumatran tiger (Panthera tigris sumatrae): A review of conservation statusAbstract The majority of wild Sumatran tigers are believed to live in 12 Tiger Conservation Landscapes covering approximately 88 000 km2 . However, the actual distribution of tigers across Sumatra has never been accurately mapped. Over the past 20 years, conservation efforts focused on the Sumatran tigers have increased, but the population contin... ... hiện toàn bộ

Some biological consequences of environmental change: A study using barnacles (Cirripedia: Balanomorpha) and gum trees (Angiospermae: Myrtaceae)Abstract Uniformitarianism permits understanding of the past on the basis of the present, and modeling the future through consideration of the fossil record. The present paper addresses the impact environmental (climatic) change has had on acorn barnacles and eucalyptus trees. Acorn barnacles (Balanomorpha) are first recorded after the K/T mass‐extinction event. In ... ... hiện toàn bộ

Physiological adaptations of small mammals to desert ecosystemsAbstract Adaptations of animals to the xeric environment have been studied in various taxonomic groups and across several deserts. Despite the impressive data that have been accumulated, the focus in most of these studies is mainly on the significance of one variable at a time. Here, we attempt to integrate between responses of several physiological systems, challen... ... hiện toàn bộ

Cultivated walnut trees showed earlier but not final advantage over its wild relatives in competing for seed dispersersAbstract Little is known about seeding regeneration of cultivated trees compared to wild relatives in areas where seed dispersers are shared. Here, we investigated the differences in seed fates of cultivated walnut (Juglans regia ) and wild Manchurian walnut (Juglans mandshurica ) trees under rodent predation and d... ... hiện toàn bộ
