Vegetation and Soil N-15 Natural Abundance in Alpine Grasslands on the Tibetan Plateau: Patterns and Implications

open access: yes, 2013
The natural abundance of nitrogen (N) stable isotopes (delta N-15) has the potential to enhance our understanding of the ecosystem N cycle at large spatial scales. However, vegetation and soil delta N-15 patterns along climatic and edaphic gradients have

Analysis of scientific production on environmental risk assessment in ecosystems with a circular economy

open access: yesDyna
Ecosystems are currently at risk, and scientific methods have been developed to assess these impacts. In this scenario, the circular economy makes it possible to reuse raw materials and reduce waste.

Software Ecosystems vs. Natural Ecosystems: Learning from the Ingenious Mind of Nature

open access: yes, 2010
The use of the term ecosystem in the context of extensible software platforms and third-party developers or user communities has made us ponder about the similarities between software ecosystems and natural ecosystems.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Information in the ecosystem: Against the "information ecosystem".

open access: yesFirst Monday, 2017
The “information ecosystem” metaphor is widely used in academic libraries and has become nearly ubiquitous when speaking of the information systems that support scholarly communication and varied forms of data sharing and publication. The trending use of this language arises from non-academic applications — for example in big data (the Hadoop ecosystem)

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
