Relation of feeding,growth, and metabolism to age in the larval,female house cricket

The maximum growth rate occurs in the first half of the 7th and 8th larval instars of the house cricket, at which time food and water consumption is maximal. Growth ceases in the last 2 to 3 days of each instar when food consumption is almost nil. The metabolic rate is twice, and the locomotory activity is four times, higher in the first 2 to 3 days than in the last 2 to 3 days of each instar. The %-gain in dry wt is 120% for the 7th and 139% for the 8th instar. The average digestive coefficient (AD) for the 8th instar is 67% and the average efficiency of food conversion to tissue (dry wt ECI) is 27%. The average daily food consumption for 8th instar larvae is 31.4 mg, and, therefore, we calculate that an average of 12 mg food is burnt per day for energy which is confirmed by the observed average V_O2 of 1.2 ml O₂/g-cricket/hr. Total lipids as %-total wt (239% mg-gain) increases in the first 4 days then remains constant in spite of cessation of feeding in the last 2 days. The RQ confirms the conversion of carbohydrates to lipids in the first half of each instar. In the moulting cycle carbohydrates are used for maintenance (when not feeding), but lipids are used at apolysis.     

广西崇左三合大洞的早更新世猪属新材料

系统记述了广西崇左三合大洞早更新世堆积中出土的与巨猿伴生的小猪(Sus xiaozhu)和裴氏猪(S.peii)。三合大洞是小猪在我国境内至少为第12个产地,也是目前最靠南的产地。小猪在三合大洞的发现进一步证实了小猪的繁盛时期是早更新世,繁盛地区在广西。三合大洞是裴氏猪在我国境内至少第9个产地, 也是裴氏猪在我国境内目前最靠南的记录。裴氏猪在三合大洞的发现同样证实了裴氏猪的繁盛时期是早更新世, 繁盛地区也在广西。虽然小猪的时代分布从早更新世早期起并可能延续到晚更新世早期, 裴氏猪的时代分布从早更新世早期到中更新世早期, 但是迄今发现的小猪与裴氏猪同时产出的层位均为早更新世地层, 而三合大洞是迄今我国境内第6个小猪和裴氏猪伴生的早更新世地点。小猪和裴氏猪也经常出现在巨猿产地, 三合大洞是迄今它们共生的第5个地点。小猪和裴氏猪在三合大洞的出现指示三合地区在早更新世具有近水的森林和灌丛环境。     

云南南涧凤凰山秋季夜间迁移鸟类多样性分析

2002年9月16日至11月28日、2003年4月6日至26日、2003年9月9日至11月26日,对云南南涧凤凰山秋季夜间迁移鸟类进行了研究。共网捕迁移鸟176种6677只,分属13目29科,其中红喉姬、红点颏、蓝歌鸲等雀形目鸟类数量优势度十分显著,表明该地迁移鸟类以雀形目等中小型鸟类为主。对网捕迁移鸟进行多样性分析,Shannon-Weaner指数为3·89,G指数为4·13,总的F指数为25·56,表明该地迁移鸟在种、属、科等分类阶元的多样性均较丰富。2002和2003年迁移鸟类多样性t检验结果表明,年间、月份间的多样性差异明显,即凤凰山迁移鸟类动态变化明显。     

贵州雷公山海南鳽繁殖记录

海南鳽（Gorsachius magnificus）隶属于鹈形目（Pelecaniformes）鹭科（Ardeidae）,为我国Ⅱ级重点保护野生动物。本文报道了2019年5月至9月海南鳽 在贵州雷公山自然保护区干脑村南柳河（26?16? N,108?06? E,海拔771 m）的繁殖情况。海南鳽巢址选择在常绿阔叶林中,营巢于高大、枝叶繁茂、枝桠较多并有很强隐蔽性的阔叶树上。结合发现海南鳽幼鸟在贵州雷公山自然保护区分布区的增加,我们认为在贵州雷公山地区应该至少有1或2个繁殖种群。本次记录是海南鳽在贵州省的首次繁殖记录。     

Macroscopic-anatomic changes of the skull, spine, spinal cord, extremities and tails of postnatal growing albino rats

27 albino-rats were used to measure the growth of skull, spinal column, spinal cord, roots of the spinal nerves, and length of tail and extremities at their 1st to the 5th, the 8th, 11th, 15th, and 20th postnatal day. The growth rate of the distal and caudal parts of the distal body was higher than of the cranial and proximal ones.     

Immunohistochemical localization of laminin, nidogen, and type IV collagen during the early development of human liver

 There is evidence that basement membrane components control differentiation of liver sinusoids and bile ducts. These processes occur in humans in the 9th gestational week (GW). Distribution of laminin, nidogen, and type IV collagen was studied during human liver development between the 6th and the 10th GW. Laminin and nidogen lined intrahepatic microvessels in the 6th and 7th GW decreasing in quantity at the beginning of the fetal period (9th–10th GW). Type IV collagen was detected in microvessels only from the 9th GW onward. In the early periportal matrix (9th–10th GW) laminin, nidogen, and type IV collagen were diffusely distributed. At these stages, basement membrane zones of larger portal vessels and of early bile ducts were also stained for all three glycoproteins. These results show that laminin and nidogen are localized in microvessels during early human liver development and decrease in concentration at the developmental stage during which microvessels become discontinuous. In contrast, type IV collagen is not present in early microvessels but occurs when laminin and nidogen disappear. The three glycoproteins occur together only in those areas of the developing liver in which, from the 9th GW onward, the differentiation of immature liver cells into biliary epithelium takes place.

Relationship of age to seasonal levels of LH, FSH, prolactin and testosterone in male, white-tailed deer

Seasonal levels of LH, FSH, Prolactin (PRL) and testosterone (T) were determined in blood plasma of penned male white-tailed deer, ranging in age from 2 to 10 yr. Peak levels of T (observed around the rutting season in November) gradually increased until the 7th yr and then they began to decline slowly; a sharp decrease was registered in the 10th yr. Peak levels of PRL (measured in June) steadily increased until the 6th yr and then dropped rapidly in the 8-9-yr-old group. Peak concentrations of FSH (observed during September-October) rose gradually until the 6th yr, decreased in 8-yr-olds and then increased again in the 9th and 10th yr of life. On the other hand LH maxima (occurring during July-September) were rising until the 4th yr and then remained steady until the 6th yr. LH peaks in the 8th and 9th yr were more than 50% higher than that of the 4-6th yr. These data indicate that increasing peak levels coincide with approaching "prime male age" around 5-7 yr. In senior bucks (9-10 yr) decreasing gonadal function may be the sign of diminished responsiveness to pituitary hormones since gonadotrophins are elevated to the "castrate-type" levels.     

Yellow wagtail Motacilla flava Linnaeus, 1758 (Passeriformes, Motacillidae, Motacillinae), in the Middle Volga Region: Geographical distribution, nesting biotopes, and numbers

A critical assessment of the literature data on the yellow wagtail Motacilla flava Linnaeus, 1758 (Passeriformes, Motacillidae, Motacillinae), at the turn of the 19th–20th centuries is carried out, assessment of its current numbers is given, and limiting factors and patterns of the species distribution on the study area of the European part of Russia, including the Middle Volga Region, are identified.     

Ontogeny of the cricket Phaeophilacris bredoides Kaltenbach (Orthoptera, Gryllidae)

Development of Phaeophilacris bredoides Kalt. was studied under stable laboratory conditions: temperature of 26°C, air humidity 60%, and 12L: 12D photoperiod (Knyazev, 1985). The life cycle of Ph. bredoides includes four stages: egg, pronymph, nymph, and adult. The duration of embryonic development is 28 days. The nymphal ontogeny lasts 230 days and consists of 25 instars. The duration of nymphal instars (days) is: 1st—16, 2nd—6, 3rd—8, 4th—10, 5th—10, 6th—15, 7th—10, 8th—8, 9th—9, 10th—11, 11th—11, 12th—8, 13th—9, 14th—10, 15th—7, 16th—9, 17th—7, 18th—7, 19th—7, 20th—10, 21st—11, 22nd—7, 23rd—9, 24th—6, and 25th—9. The duration of adult life is 126 days in males and 125 days in females. Three periods were distinguished in the imaginal ontogeny of males and females: pre-reproductive, reproductive, and post-reproductive. The pre-reproductive period begins with the molt to the adult and ends with the onset of reproductive behavior in males and with the first copulation in females. Its duration is 4 (3–6) days in males and 5 (2–7) days in females. The reproductive period in males starts with the onset of reproductive behavior on the 4th (3rd–6th) day and lasts 119 (98–135) days. In females it begins when they start responding to males’ courtship behavior and lasts 116 (97–133) days. The female reproductive period includes two alternating phases: copulation and egg-laying. The egg-laying phase is initiated by successful copulation. The post-reproductive period in females starts when oviposition ceases and in males, when their reproductive behavior disappears. This period lasts about 3 (2–3) days in males and 4 (2–7) days in females, until the insect dies.
