Scratching the Surface and Digging Deeper: Exploring Ecological Theories in Urban Soils [PDF]

open access: yes, 2009
Humans have altered the Earth more extensively during the past 50 years than at any other time in history (Millennium Assessment 2003). A significant part of this global change is the conversion of land covers from native ecosystems to those dominated by

Urban political ecology: a critical reconfiguration

open access: yesProgress in Human Geography, 2021
Urban political ecology now finds itself at a crossroads between gradual marginalization or renewed intellectual impetus. Despite some recent critical re-evaluations of the field, there remain a series of conceptual tensions that have only been partially

Alternating High‐Fat and Polysaccharide Diets Modulates Gut Phage‐Bacterial Interplay

open access: yesAdvanced Science, EarlyView.
This study reveals how alternating high‐fat and polysaccharide diets reshape the human gut virome and enhance phage‐bacteria interactions. Using large‐scale metagenomic meta‐analysis and a time‐resolved mouse model, the authors show that diets strongly modulate phage abundance, lifestyle, and gene exchange, offering new insights into nutrition‐guided ...

Conducting urban ecology research on private property: advice for new urban ecologists

open access: yesJournal of Urban Ecology, 2019
Private property makes up a large proportion of urban green space and differs from public green space in ecologically important ways. While including private property in urban landscape research is necessary, ecologists are frequently unprepared to work ...

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

open access: yesAdvanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Nanosized microbiomes from pig manure alter soil microbial communities and increase antibiotic resistance gene abundance

open access: yesCommunications Earth & Environment
Agricultural ecosystems are continuously exposed to exogenous phages, including those introduced via animal manure fertilization, yet their colonization dynamics and ecological impacts remain unclear. Using a microcosm experiment, we investigated how pig

Mapping the “Supply–Demand–Flow” of Ecosystem Services for Ecosystem Management in China

open access: yesAdvanced Science, EarlyView.
This study develops a “supply–demand–flow” framework clarifies how ecosystem services move between regions by distinguishing potential and actual supply and demand. Using integrated biophysical–socioeconomic modeling, nine services in China were mapped.
