Increasing evidence indicates that the loss of soil microbial α-diversity triggered by environmental stress negatively impacts microbial functions; however, the effects of microbial α-diversity on community functions under environmental stress are poorly understood. Here, we investigated the changes in bacterial and fungal α- diversity along gradients of five natural stressors (temperature, precipitation, plant diversity, soil organic C and pH) across 45 grasslands in China and evaluated their connection with microbial functional traits. By quantifying the five environmental stresses into an integrated stress index, we found that the bacterial and fungal α-diversity declined under high environmental stress across three soil layers (0-20 cm, 20-40 cm and 40-60 cm).

Introduction: We developed and validated age-related amyloid beta (Aβ) positron emission tomography (PET) trajectories using a statistical model in cognitively unimpaired (CU) individuals.
Methods: We analyzed 849 CU Korean and 521 CU non-Hispanic White (NHW) participants after propensity score matching. Aβ PET trajectories were modeled using the generalized additive model for location, scale, and shape (GAMLSS) based on baseline data and validated with longitudinal data.

Mixed-species forests are proposed to enhance tree resistance and resilience to drought. However, growing evidence shows that tree species richness does not consistently improve tree growth responses to drought. The underlying mechanisms remain uncertain, especially under unprecedented multiyear droughts.

Introduction: In various countries, an increasing proportion of general practitioner (GP) referrals is returned by hospitals. We aimed to uncover the causes and consequences of referral returns from the perspective of GP liaisons.
Methods: Individual interviews with 20 GP liaison officers from various departments in Southern Denmark, serving 1.

Using longitudinal national prescribing data, we estimated the number of transgender and gender-diverse individuals initiating gender-affirming hormone therapy (GAHT) from 2013 to 2024 in Australia. Between 2013 and 2024, 11 883 individuals initiated testosterone-based GAHT and 20 358 initiated oestrogen-based GAHT. Initiation rose from 1118 in 2013 to 5135 in 2024, with a growing share accessing testosterone-based GAHT over time.
