Open Questions on Ion–Neutral Collisions and Coupling in the Lower Thermosphere–Ionosphere: Electrodynamics, Energetics and DynamicsNARA Subscribed
The Lower Thermosphere–Ionosphere (LTI) is the interface region between the Earth’s atmosphere and space. It is modulated by the energy and momentum deposition from the magnetosphere above and by the impacting waves from the lower atmosphere. The LTI region is defined by the co-existence and interaction of neutral and ionized species within the region’s electric and magnetic fields. This interplay results in unique and complex...
Age-dependent drivers of sex-specific disappearance in wild redfronted lemurs: the role of behaviorNARA Subscribed
In humans, frailty, risk-taking behaviors, and unhealthy lifestyles have been linked to shifts in adult sex ratios (ASR), which are heavily female-biased at older ages. Conversely, Madagascar’s group-living primates frequently exhibit male-biased ASRs, defying patterns commonly observed among polygynous mammals. To explore these unusual sex ratio dynamics in wild redfronted lemurs ( Eulemur rufifrons ), we examined three behav...
Integrating observations and experiments, we address the progressive effects of three alien species, the mussels Mytilus galloprovincialis and Semimytilus patagonicus , and the barnacle Balanus glandula , on limpet species in South Africa. We describe four aspects: (1) Interactions among algae, the limpet Scutellastra granularis and M. galloprovincialis . (2) The influences of B. glandula on S . granularis and on the periwinkl...
This study assessed the effectiveness of no-take areas in the Table Mountain National Park MPA in protecting the biodiversity of intertidal rocky shores from impacts of harvesting. Surveys were conducted in areas of controlled harvesting and in no-take areas to compare the densities and sizes of exploited species and the community composition between shores experiencing these two levels of protection, in two ecoregions and on...
Two newly discovered specimens of passerine birds—an isolated sternum and an associated skeleton—from the upper Middle Miocene (ca. 12 Ma) are the oldest representatives of Passeriformes from Austria. Although the condition of the specimens prevents their accurate identification, they provide further clues on the morphological diversity of the avifauna during this period and fill gaps in the paleobiogeography of Miocene passer...
Most sedentary marine animals disperse from their place of origin during their initial life stages as larvae. The delivery of planktonic larvae back to coastal adult habitats after weeks or months of offshore development is commonly thought to be stochastic, resulting in large recruitment fluctuations and making predictive understanding of population dynamics difficult. Time series of invertebrate settlement on intertidal shor...
