Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

open access: yesIntegrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

DNA Methylation of Igf2r Promoter CpG Island 2 Governs Cis-Acting Inheritance and Gene Dosage in Equine Hybrids

open access: yesBiology
Genomic imprinting is critical for mammalian development, but its regulation varies across species. The insulin-like growth factor 2 receptor (IGF2R), which is a maternally expressed imprinted gene critical for cell proliferation and differentiation, as ...

Resource Availability and Habitat Quality Drive Time‐Lag Effects in High‐Altitude Ungulate Distribution

open access: yesIntegrative Zoology, EarlyView.
Our analysis revealed that while climate strongly influenced species distributions, habitat change drove most observed delays in distribution responses. In terms of community ecology, dispersed communities exhibited shorter time lags than concentrated groups. Analyses of lag duration revealed a 5–6‐year distribution lag effect in high‐altitude ungulate

An Overview of the Rock Art of AlUla: Tracing Changes in Content and Form Across 12,000 Years of Human History

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

open access: yesArchaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

CliqueStream: an efficient and fault-resilient live streaming network on a clustered peer-to-peer overlay

open access: yes, 2008
Several overlay-based live multimedia streaming platforms have been proposed in the recent peer-to-peer streaming literature. In most of the cases, the overlay neighbors are chosen randomly for robustness of the overlay.
