Ants mediate the structure of phytotelm communities in an ant-garden bromeliad [PDF]

, 2010
The main theories explaining the biological diversity of rain forests often confer a limited understanding of the contribution of interspecific interactions to the observed patterns.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Will improving wastewater treatment impact shorebirds? Effects of sewage discharges on estuarine invertebrates and birds [PDF]

, 2012
Human communities often discharge wastewaters into estuaries, influencing their organic and pollutant loading, benthic community and trophic structure.

Nanocrystalline Cellulose from the Solitary Tunicate Phallusia Mammillata, a Valuable Nanocellulose Precursor

Advanced Sustainable Systems, EarlyView.
This study explores the potential of locally harvested Phallusia mammillata, a tunicate usually discarded as waste from mussles farming as a viable source for producing various high‐grade cellulose derivatives in the form of nanofibrils (NFC) and nanocrystals (CNC). Abstract Ascidians are ubiquitous filter‐feeding marine invertebrates, the only animals

Insect‐Microbe‐Based Laccase: Untapped Natural Resource for Industrial and Biotechnological Applications

Advanced Sustainable Systems, EarlyView.
The insect‐microbe interplay fulfills a key ecological role involving the degradation of ligninocellulose biomass. This is coordinated by the secretion of different kinds of proteins, of which ligninolytic enzymes, such as laccases (Lacs), are of prime importance.

The influence of nutrient concentration on algal biomass and invertebrate communities in agricultural streams : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University, Palmerston North, New Zealand [PDF]

, 2003
High nutrient inputs have generally been identified as responsible for the degradation of lowland rivers and lakes in New Zealand and internationally. Nutrients have been shown to influence algal community growth rate and composition.

iDNA from terrestrial haematophagous leeches as a wildlife surveying and monitoring tool - prospects, pitfalls and avenues to be developed [PDF]

, 2015
Invertebrate-derived DNA (iDNA) from terrestrial haematophagous leeches has recently been proposed as a powerful non-invasive tool with which to detect vertebrate species and thus to survey their populations.

Alistipes senegalensis is Critically Involved in Gut Barrier Repair Mediated by Panax Ginseng Neutral Polysaccharides in Aged Mice

Advanced Science, EarlyView.
An integral functional axis through which GPN and functional metabolites of Alistipes senegalensis can hydrolyze tryptophan into indoles. Furthermore, the Alistipes senegalensis‐indole‐AhR pathway is found to be associated with increased expression of tight junction‐associated proteins and activation of gut stem cells.

Responses of a bacterial pathogen to phosphorus limitation of its aquatic invertebrate host [PDF]

, 2008
Host nutrition is thought to affect the establishment, persistence, and severity of pathogenic infections. Nutrient-deficient foods possibly benefit pathogens by constraining host immune function or benefit hosts by limiting parasite growth and ...

Hosts and Commensal Bacteria Synergistically Antagonize Opportunistic Pathogens at the Single‐Cell Resolution

Advanced Science, EarlyView.
In the tripartite‐species model, Drosophila larvae stimulate lactate production through excreting digestion enzymes. S. marcescens population senses a cue of lactate and tends to diverge into virulent and reduced virulence subclusters with remarkable heterogeneity to metabolize carbon metabolism and counter colonization resistance, giving a fitness ...
