Harnessing large language models for coding, teaching and inclusion to empower research in ecology and evolution

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 10, Page 1757-1763, October 2024.
Abstract Large language models (LLMs) are a type of artificial intelligence (AI) that can perform various natural language processing tasks. The adoption of LLMs has become increasingly prominent in scientific writing and analyses because of the availability of free applications such as ChatGPT. This increased use of LLMs not only raises concerns about

黑猩猩精液冷冻和优选研究

open access: yes野生动物学报, 2011
对精液进行有效的冷冻保存和解冻优选是人工授精顺利开展的重要步骤。本研究在黑猩猩上做了尝试,分别用人工按摩采精、电刺激采精、附睾采精进行6次精液采集,所测精子活率为0.65~0.90,密度为1.69×1010~6.64×1011(个/L)。用自配精液冷冻液,采用CL-8800程序降温仪成功对所采集的精液进行冷冻保存。在冷冻后的10~400 d,分别对6次冻精解冻,并用人用精液优选试剂盒对其后3次进行解冻后优选。结果显示,解冻后精液活率为0.35~0.7;优选后精液活率为0.85~0.9,密度为4.5 ...

乌苏里貉电刺激人工采精技术获得成功

open access: yes野生动物学报, 1985
貉的电刺激人工采精和授精技术,目前国内尚无先例,也未见国外报道。黑龙江省土畜产进出口公司和哈尔滨野生饲养技术人员联合组成的科研试验组,自一九八四年十一月开始进行貉的电刺激人工采精和人工技精技术的研究。目前,已初获成功。设试验组,利用自行设计的电刺激采精设备,采用直肠探子法,对乌苏里貉进行79次电刺激采精实验 ...

东北马鹿雌性生殖器官

open access: yes野生动物学报, 1983
东北马鹿是半驯养状态的野生动物。近年来为了提高马鹿种群质量和产茸量,人工授精技术的研究已有所进展。与人工配种休戚相关的问题是必须了解雌性生殖器官的构造。有关这方面的报导尚未见到。本文主要就马鹿雌性生殖器官的观察得出初步报导,希望能对马鹿的人工授精提供形态学依据。 1981年秋到1982年春,在黑龙江省绥棱农场的马鹿饲养场进行该项研究工作。共计屠宰母马鹿40余头 ...

秦岭大熊猫繁殖期尿液中生殖激素变化规律的研究

open access: yes野生动物学报, 2020
为探索秦岭大熊猫(Ailuropoda melanoleuca)繁殖期生殖激素变化规律,确定最佳人工授精时间及成功受孕大熊猫产仔时间,本文采用ELISA方法,对陕西省林业科学院秦岭大熊猫繁育研究中心2017—2019年16例雌性大熊猫繁殖期尿中雌酮(E1G)和孕酮(P4)进行了检测分析,结果表明发情期雌性大熊猫发情持续天数6—15 d不等,平均108 d,E1G峰值580—2400 ng/mgCr,平均1477 ng/mgCr,首次人工授精时间在E1G/Cr峰值后平均298 h ...
