Camera traps are widely used in wildlife research and monitoring, so it is imperative to understand their strengths, limitations, and potential for increasing impact. We investigated a decade of use of wildlife cameras (2012-2022) with a case study on Australian terrestrial vertebrates using a multifaceted approach. We (i) synthesised information from a literature review; (ii) conducted an online questionnaire of 132 professionals; (iii) hosted an in-person workshop of 28 leading experts representing academia, non-governmental organisations (NGOs), and government; and (iv) mapped camera trap usage based on all sources.

Schizophrenia (Heidelb)
October 2024
The increasing availability of biobanks is changing the way individuals are identified for genomic research. This study assesses the validity of a self-reported clinical diagnosis of schizophrenia. The study included 1744 clinically-ascertained participants with schizophrenia or schizoaffective disorder depressed-type (SA-D) diagnosed by self-report and/or research interview and 1453 UK Biobank participants with self-reported and/or medical record diagnosis of schizophrenia or SA-D.

- The study examined how positive, negative, and disorganized psychotic symptom dimensions relate to different clinical and developmental variables, addressing inconsistencies in definition and prior research.
- Results showed that higher symptom scores were linked to poor social adjustment, earlier onset of symptoms, and specific demographic factors, such as ethnicity and gender.
- The findings also suggested a significant familial influence on disorganized symptoms, highlighting the connections between these symptoms and lower premorbid IQ, especially within monozygotic twin pairs.
Article Synopsis
- The study examines the link between perimenopause (the years surrounding the final menstrual period) and the risk of developing various psychiatric disorders in women.
- Data from 128,294 participants in the UK Biobank revealed that the incidence of psychiatric disorders, particularly major depressive disorder (MDD) and mania, significantly increased during perimenopause compared to earlier reproductive stages.
- While the incidence of MDD during perimenopause had an increased rate ratio of 1.30, mania showed a larger effect size with a rate ratio of 2.12; however, no significant relationship was found between perimenopause and schizophrenia spectrum disorders.
