Land management shapes drought responses of dominant soil microbial taxa across grasslands.

Soil microbial communities are dominated by a relatively small number of taxa that may play outsized roles in ecosystem functioning, yet little is known about their capacities to resist and recover from climate extremes such as drought, or how environmental context mediates those responses. Here, we imposed an in situ experimental drought across 30 diverse UK grassland sites with contrasting management intensities and found that: (1) the majority of dominant bacterial (85%) and fungal (89%) taxa exhibit resistant or opportunistic drought strategies, possibly contributing to their ubiquity and dominance across sites; and (2) intensive grassland management decreases the proportion of drought-sensitive and non-resilient dominant bacteria-likely via alleviation of nutrient limitation and pH-related stress under fertilisation and liming-but has the opposite impact on dominant fungi. Our results suggest a potential mechanism by which intensive management promotes bacteria over fungi under drought with implications for soil functioning.

Mature cystic teratoma of both the fallopian tube and contralateral ovary: a case report.

UNLABELLED: Intratubal teratoma is a very rare condition. The authors believe to present the first case of a completely intratubal mature cystic teratoma with a contralateral intraovarian teratoma. Preoperative ultrasound examination allowed the intraoperative diagnosis of this rare condition, hence allowing appropriate surgical management. MATERIALS AND METHODS: A 19-year-old woman presented with a history of pelvic pain and severe dysmenorrhea. Ultrasound examination initially suggested bilateral ovarian dermoids. Upon laparoscopy, the distal left fallopian tube was obstructed and contained an inflammatory mass adhered to the rectosigmoid. The left ovary was entirely normal. A contralateral intraovarian dermoid was also identified. CONCLUSION: Although rare, when an intratubal mass is identified, consideration of intratubal dermoid should be given. Preoperative ultrasound can be of critical importance to the intraoperative diagnosis.
