Human-biting behaviour of Leptoconops irritans (Diptera: Ceratopogonidae) in a touristic area of the Balearic Islands (Spain).

Applied Zoology and Animal Conservation Group, University of the Balearic Islands (ZAP-UIB), Palma, Spain.
Biting midges of genus Leptoconops Skuse 1889 are small blood-feeding insects recognized as highly irritating diurnal pests in certain regions around the globe. In Europe, their presence is poorly documented, except in France and Italy. Following reports of human discomfort in a tourist area of Menorca, Balearic Islands (Spain), a small-scale study was conducted to identify the biting species and assess their preferred biting sites using a human-landing assay along a habitat gradient in a coastal dune area.

Indian J Psychiatry

Department of Psychiatry and Psychotherapy, University Hospital Hamburg-Eppendorf, Hamburg, Germany.
Background: Glucocorticoids increase fear extinction in preclinical and human studies. Endogenous cortisol might influence who will benefit from exposure therapy in anxiety-spectrum disorders.
Methods: To investigate the impact of cortisol levels on within-session habituation of distress - a measure of success of exposure therapy - in obsessive-compulsive disorder (OCD) fifty-one OCD patients were studied during their stressful first cognitive-behavioral exposure therapy session with response prevention.
Stress and telomere length in leukocytes: Investigating the role of GABRA6 gene polymorphism and cortisol.
Psychoneuroendocrinology
January 2025
Department of Experimental Clinical and Health Psychology, Ghent University, Ghent, Belgium. Electronic address:
Telomere length (TL) is considered a biomarker of aging, and short TL in leukocytes is related to age and stress-related health problems. Cumulative lifetime stress exposure has also been associated with shorter TL and age-related health problems, but the mechanisms are not well understood. We tested in 108 individuals whether shorter TL in leukocytes is observed in individuals with the GABRA6 TT genotype, which has been associated with dysregulation of hypothalamic-pituitary-adrenal axis activity (the main biological stress system) compared to the CC genotype.

College of Biological Resource and Food Engineering, Qujing Normal University, Qujing 655011, China.
Bumblebee species are vital wild pollinators, providing essential pollination services for various crops, fruits, and vegetables. However, their biodiversity is vulnerable to decline due to climate change, particularly in regions like northern Pakistan. Despite this, no research has yet been conducted on the distribution patterns of bumblebee species in this region.

Department of Zoology and Entomology, University of Pretoria, Pretoria, 0002, South Africa; Mammal Research Institute, University of Pretoria, Hatfield, 0083, South Africa. Electronic address:
The genus Otomys exhibits diverse activity patterns in the field, making them ideal subjects for studying circadian biology. The Southern African vlei rat (Otomys auratus) has previously been categorised as diurnal or crepuscular, but also displays some nocturnal activity. This study aimed to confirm the temporal niche of vlei rats in a laboratory setting and examine changes in activity when provided with a running wheel.
