Non-native species have higher consumption rates than their native counterparts.

Non-native species can be major drivers of ecosystem alteration, especially through changes in trophic interactions. Successful non-native species have been predicted to have greater resource use efficiency relative to trophically analogous native species (the Resource Consumption Hypothesis), but rigorous evidence remains equivocal. Here, we tested this proposition quantitatively in a global meta-analysis of comparative functional response studies.

- Riverine physical and chemical characteristics significantly impact ecosystem integrity, species richness, and diversity, with potential effects on community structure through competition and predation.
- The study assessed water and sediment quality at eight sites in Nelspruit, South Africa, using macroinvertebrates as bioindicators, revealing significant seasonal and site-based differences in water and sediment chemistry.
- A total of 4470 macroinvertebrate taxa were identified, with dominant groups being Crustacea and Diptera, indicating variations in community structure and the importance of monitoring aquatic ecosystems amidst increasing pollution pressures.
Background: Iatrogenic suprascapular nerve injury secondary to posterior drilling or screw penetration is a recognized complication of bone block or coracoid process transfers for anterior glenohumeral instability. We present the first cadaveric study that assesses the safety of posteroanterior reference guides and quantifies the relationship of the suprascapular nerve to posterior glenoid fixation with suture buttons.
Methods: Anterior glenoid bone block reconstruction with suture buttons utilizing a posteroanterior reference guide was performed in 10 fresh frozen cadavers via a posterior portal.
Article Synopsis
- The audit aimed to assess and improve the completeness and accuracy of the National Joint Registry (NJR) dataset specifically for elbow arthroplasty surgeries.
- In a two-phase approach, Phase 1 compared NJR data with NHS England Hospital Episode Statistics (HES), identifying thousands of unmatched and inaccurate records, particularly for radial head arthroplasties (RHAs).
- Phase 2 involved collaboration among 142 NHS hospitals to correct and update records, resulting in an improved completeness of the NJR dataset from 63% to 93% and accuracy from 94% to 98%.
Purpose: Pseudoachondroplasia is a rare skeletal dysplasia caused by a mutation in the COMP gene. Infants with pseudoachondroplasia present with rhizomelic dwarfism. Pseudoachondroplasia can resemble achondroplasia, which also presents with a phenotype of rhizomelic dwarfism.
