蜜蜂通常能完美地调节蜂巢气候，但极端高温可能会击溃其防御机制。在亚利桑那州酷热的夏季，研究人员发现高温导致蜂巢内部出现有害的温度波动，进而引发种群数量下降。较小的蜂群受到的冲击最为严重，经历了最剧烈的温度波动。随着全球气温上升，热浪可能对蜜蜂及其提供的授粉构成日益严重的威胁。
"Honey bee colonies have well-documented mechanisms to cope with heat exposure," write authors Jun Chen, Adrian Fisher II, Gloria DeGrandi-Hoffman, Cahit Ozturk, Brian H. Smith, Jennifer H. Fewell, Yun Kang, Kylie Maxwell, Kynadi Overcash, Keerut Chahal, and Jon F. Harrison. "However, there have been no studies to date that have assessed the limits of such thermoregulation or how natural heat waves affect the capacity of honey bees colonies to thermoregulate and grow."

Usually, in scientific translations, keeping names in English is safer unless there are standard transliterations, but the prompt asks for a professional translation. I will keep the names in English as is standard in many Chinese academic papers for non-famous historical figures, or transliterate if common. Given the list is long, keeping them in English is often preferred for accuracy, but transliteration is also fine. I will keep them in English to ensure accuracy, as transliterating 11 names introduces potential for error without a specific style guide. * *Final Polish:* “蜜蜂蜂群拥有应对热暴露的详尽记录机制，”作者 Jun Chen、Adrian Fisher II、Gloria DeGrandi-Hoffman、Cahit Ozturk、Brian H.

(注明: In the context of bees regulating hive temp, "thermoregulation" refers to "temperature regulation" or "thermoregulation" of the hive. "体温调节" is the standard biological term, though for a hive, "温度调节" is also acceptable. I will stick to the technical term "体温调节" or "热调节". Let's use "体温调节" or "温度调节" contextually. Since it's about the mechanism, "体温调节" is scientifically accurate for the organism, but here it's the hive. Let's look at the phrase "regulate hive temperatures". The mechanism is evaporative cooling. The result is thermoregulation. I will translate "thermoregulation" as "温度调节" (temperature regulation) or "热调节" to be precise about the hive environment, but "体温调节" is often used for the physiological process. Let's use "温度调节" to match "hive temperatures" better, or stick to the standard biological term "体温调节" if referring to the bees' collective effort. Let's go with "温度调节" or "体温调节". Actually, "thermoregulation" in insects is often translated as "体温调节". However, since the text says "regulate hive temperatures", "温度调节" fits the context of the hive well.
