Soil‐derived, gut‐dominant generalist bacteria shape the fitness of folivorous larvae

open access: yesiMeta, EarlyView.
Whether Lepidoptera harbor a conserved core gut microbiome has long remained contentious. Through large‐scale microbiome profiling of folivorous larvae, their host plants, and associated soils across three climatically distinct regions of China, we identify two soil‐derived generalist bacteria, Ralstonia insidiosa and Delftia sp., that colonize 97.92 ...

The regulation of stem cell fate and its application in neural regeneration

open access: yesInterdisciplinary Medicine, EarlyView.
Regulating stem cell fate is crucial for neural regeneration. This review summarizes key physical, biological, and chemical strategies and their applications in repairing nerve injuries, providing new insights for regenerative medicine. Abstract Regulating the fate of stem cells (SCs) is a key technical problem in the field of regenerative medicine and

Effects of climate on size structure and functioning of aquatic food webs [PDF]

open access: yes, 2010
In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Influence of Habitat Use on Prey Capture Behavior and Kinematics in the Pyrenean Brook Newt (Calotriton asper)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Caves are extreme environments that impose stringent selective pressures on organisms. Consequently, many cave dwellers show extreme adaptations such as the loss of eyes, depigmentation, and a low resting metabolic rate. Yet, how the initial stages of adaptation to these extreme environments take place remains poorly understood.

Microbial communities and functional diversity in seafood

open access: yesJSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

An Unexpected Role of Local Selectivity in Social Promotion [PDF]

open access: yes
A selection process and a hierarchical promotion system in a dynamic model are considered as in Harrington (1998) and Garcia-Martinez (2010), where agents are "climbing the pyramid" in a rank-order contest based on the "up or out" policy.

Health risk assessment of heavy metal accumulation in fruits exposed to geothermal waters: a case study and global implications

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The present study investigated the potential health risks of heavy metals (HMs) in the fruits and leaves of mulberry and sour cherry trees exposed to water from Sivas geothermal basin (Turkey). RESULTS The target HMs were ranked according to their hazard index as: Cd < Pb < Zn < Cu < Ni < Mn < Cr. The total hazard index for mulberry
