Small entire functions with extremely fast growth [PDF]

open access: yes, 1997
We prove in this note that, given α ∈ (0, 1/2), there exists a linear manifold M of entire functions satisfying that M is dense in the space of all entire functions such that limz→∞ exp(|z|α)f(j)(z) = 0 on any plane strip for every f ∈ M and for every ...

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.

Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

open access: yesWildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

Long‐term warming drives mineral‐associated organic carbon accumulation on the Tibetan Plateau

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Global warming affects both plant growth and soil microbial decomposition, creating uncertainty for the storage and persistence of soil organic carbon (SOC) stock. Limited decomposition rates often characterise cold alpine ecosystems.

Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

open access: yesIntegrative Zoology, EarlyView.
Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...
