A Sequential Release Micro‐nano System for Colitis Therapy via Gut Microbiota and Immune Regulation

open access: yesAngewandte Chemie, EarlyView.
The micro‐nano system achieves the sequential release of drugs in response to gut microbiota and reactive oxygen species (ROS). Inulin prebiotics restore gut microbiota balance. Selenium compounds scavenge ROS and promote macrophage polarization, while 3‐oxolithocholic acid suppresses TH17‐cell differentiation. As a multifactorial therapeutic approach,

From habitat decline to collapse: a spatially explicit approach connecting habitat degradation to destruction [PDF]

open access: yesarXiv
Habitat loss, driven primarily by anthropogenic activity, significantly threatens ecosystem sustainability. While it is well understood that habitat loss is the leading contributor to declines in biodiversity worldwide, the connection between habitat degradation, destruction, and different locomotion strategies remains unclear.

Soil biome variation of Lupinus nipomensis in wet‐cool vs. dry‐warm microhabitats and greenhouse

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Environmental DNA (eDNA) can be used to determine the composition of the soil biome community, revealing beneficial and antagonistic microbes and invertebrates associated with plants. eDNA analyses can complement traditional soil community studies, offering more comprehensive information for conservation practitioners. Studies are also

Spatially explicit population modeling with habitat preferential movement of Glis glis (Edible dormouse) [PDF]

open access: yesarXiv
In this study, we present a population dispersal model for Glis glis, a rodent species with a strong preference for forest habitats. The model addresses dispersal processes by incorporating the ecological traits, including habitat preferences of the species, potential growth rate, home range, and carrying capacity.

Habitat- und Nahrungswahl

open access: yes, 2012
Jedes Tier muss regelmasig Nahrung zu sich nehmen, um die energetischen Grundlagen fur Wachstum, Aufrechterhaltung der Grundfunktionen und Reproduktion zu gewahrleisten. Daher kommt der Suche, Auswahl, Verteidigung und Aufnahme von Nahrung im Verhaltensrepertoire der meisten Arten eine wichtige Funktion beim tagtaglichen Uberleben zu.

Phylogenomics, historical biogeography, and diversification of leaf traits in the Malagasy‐endemic genus Uncarina (Pedaliaceae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Uncarina contains 14 species of woody plants endemic to Madagascar. Its occurrence across dryland biomes on the island make it an interesting system to study the diversification of the flora. Methods Using samples of all species and 512 nuclear loci, we reconstructed phylogenetic trees to examine species relationships and assess their ...
