感官經驗對朱文錦之行為調控

In this research, we investigated the interactions between goldfish’ (Carassius auratus) sensory experiences (electric shock, high osmotic pressure and colors). We separated the sensory experiences into two parts. One of them, we used different kinds of environmental color-models to analyze goldfish’s environmental preference behavior and different kinds of stress experience(electric shock and high osmotic pressure) to build the animal model of environmental preference behavior. We found that goldfish prefer brown-colored environment (compared with white) and different stress has different effects on fish’s environmental preference behavior. It proves that fish has the ability to learn and memorize the stress experience and shows that there are complicated interactions among environmental stimulus, memories of stress and behaviors caused by different kinds of stress. Also, we investigated the interactions between spatial memory and color distinction. We measured the duration of goldfish getting through the color-marked barriers driven by regular electric shock. We found that goldfish spend less time to get through color-marked barriers than those unmarked. It shows that there are some interactions between spatial memory and color distinction. In conclusion, the research proves that different sensory experiences can affect goldfish’s behaviors.本實驗利用感官經驗(電擊、高滲透壓、色彩),探討與朱文錦(Carassius auratus)行為調控的交互作用。我們將感官經驗分成兩模式:利用環境色彩特徵的差異,探討不同逆境刺激經驗(施予電擊或高滲透壓環境),與魚類環境偏好行為的交互作用,建立朱文錦環境偏好行為之動物模式。我們發現朱文錦偏好土色環境(相對於白色環境),而不同性質的逆境經驗,對魚類的環境偏好行為具有不同的影響,顯示魚類具有記憶逆境環境的學習能力,且證明「環境刺激—經驗(記憶)—行為表現」三者之間具複雜的交互作用。另外,我們亦探討空間記憶與色彩辨識的交互作用,利用規律的電擊刺激使朱文錦通過有色彩標示的關卡,以研究色彩差異與空間變化對朱文錦通過關卡能力的影響。我們發現色彩的標示可降低通過關卡的時間,且不同的色彩具不同程度的效果,顯示空間記憶與色彩辨識具交互作用。本實驗證明了不同的感官經驗或刺激,對朱文錦的行為調控具質與量的差異。

一后多夫否?黑棘蟻(Polyrhachis dives)聚落生殖策略之研究

A vast amount of research has been conducted on various ant species such as Monomonum pharaonis, Formica rufa, and Lasius niger, demonstrating the coexistence of polygyny and monogyny colonies. In polygyny colony, the high heredity variability of filial generation could be expected, but what could the monogyny colony do to hold the high heredity variability in order to increase the fitness? I hope I can account the sex ratio in the colony of spiny weaver ants, Polyrhachis dives, and compare the different colony with different reproductive strategies. I also want to check by V8 that the colony can form a polygyny colony and virgin queens can mate with many males of the same colony in the artificial nest. The results suggest that in the colony of spiny weaver ants, the higher the number of the dealate queens, the lower the number of the male. In the monogyny colony, workers control the sex ratio. According to the observation, we can see the alate adult mate in the artificial nest, and multimating can be recorded for the first time. The following study was there for undertaken to examine what’s the aftereffect made by the Reproductive strategies of polygyny colony and monogyny colony.在多后聚落內,子代變異度高是可以預期的,但是單后聚落中,又如何維持遺傳的變異度以增加其對環境的適應力呢?我們希望能計算黑棘蟻聚落組成,比較不同生殖策略的聚落之各種性比,並且錄影證實黑棘蟻聚落可以為多后聚落並進行巢內自交。我們發現:黑棘蟻聚落內,蟻后數愈高,則雄蟻比例較低;單后聚落之性比決定於工蟻;而根據錄影觀察,聚落中的有翅生殖族可在人工蟻巢中完成交配,多次交配的現象首次被實地紀錄,並且佔所有交配新生蟻后的92.8%。本實驗可利用黑棘蟻來了解單后與多后聚落的生殖策略對其族群發展的影響。

蜚腸知味-探討不同味覺刺激對美洲蟑螂口器及前腸活性的影響

前饋(feed-forward)是一種於生理反應發生之前,所進行的調節機制,為即將發生的生理作用進行準備。前人對於蟑螂消化道的前饋作用,大多著墨在酵素分泌的調節作用。本研究以美洲蟑螂作為實驗動物,觀察蟑螂消化道中前腸的組織型態,並以肌肉電位圖(electromyography, EMG)的記錄方式,探討探討味覺刺激對蟑螂嗉囊與砂囊肌肉活動的調節作用。我們發現蟑螂的消化道由橫紋肌所構成,有別於人類消化道主要由平滑肌所構成。由EMG的紀錄得知,餵食葡萄糖溶液時,可增加蟑螂嗉囊肌肉的放電幅度;而餵食味精(麩胺酸)溶液時,可增加砂囊肌肉放電幅度,推測葡萄糖與麩胺酸各可引發嗉囊與砂囊肌肉的收縮活動,皆屬於前饋機制的例子;若以清水清洗口器時,亦會引發前腸肌肉的放電行為,推測為清洗口器時引發吞嚥反射所致。

Biological control of Aphis craccivora Koch., a common pest of the cow pea Vigna unguiculata(L.)

The purpose of this project is to control the Aphis craccivora Koch. on the cow pea Vigna unguiculata (L.) by using two predators, the earwigs (black) beetle, Proeus simulans Stallan and the ladybird beetle, Micraspis discolor (F.). The experiments were carried out in the closed system in the laboratory and in the opened field with various ages of Proeus simulans Stallan and Micraspis discolor (F.) from the 1st - 4th stage of embryo to the adult form. Prior to the study in the field, the capability of the predators, Proeus simulans Stallan and Micraspis discolor (F.), that can eat the Aphis craccivora Koch. within a period of time was set up in the laboratory. The result showed that the 1st-4th stage of embryo of Micraspis discolor (F.) can eat 8.46+1.25 – 12.50+0.60, at 95% confidence, Aphis craccivora Koch. per day, while its adult can eat at the average number of 43.66 + 0.78, at 95% confidence, per day. The 1st–3rd stage of Proeus simulans Stallan embryo and the adult form can eat Aphis craccivora Koch. at the average number of 2.37+0.33 – 3.74+0.29 and 9.84+0.36, at 95% confidence, per day, respectively. This data showed that Micraspis discolor (F.) was more efficiency as predator than Proeus simulans Stallan. The insecticide activity of these two predators in the closed field (8 m x 9 m) was then determined. The number of Aphis craccivora Koch. on the plant was randomly counted everyweek for 10 weeks. It was found that the number of Aphis on the experimented and control groups were 16.20+4.30 and 2,582.00+102.40, at 95% confidence, per plant, respectively. The result support the efficiency of the two predators in controlling the pest. When the experiment was set up at the two opened field (6 m x 30 m, each field), 27.51+2.74 and 52.11+5.21, at 95% confidence, of Aphis craccivora Koch. were found on the plant of experimented and control groups, respectively, at the 10th week. The lower number of Aphis on the control plant might possilbly due to the interference from natural predators. From this study, the biological control of Aphis craccivora Koch. on the cow pea Vigna unguiculata (L.) could be achieved by using Proeus simulans Stallan and Micraspis discolor (F.). To avoid the use of chemical insecticides, biological control should be trained to farmers to help reduce the environmental problem.

黑棘蟻聚落的生物時鐘

This study is to investigate whether colony of the spiny-weaver ant, Polyrhachis dives, have biological clock so as to observe the locomotion activities of the ants in the nest and find out if the Light period will interfere the rhythm. The conclusion is the colony of the ants get the rhythm is 23.8 hours during in L:D=12:12.There are ants not significant difference between large colonies and small colonies. While in Dark (D:D)the ants appears free running with 23.1 hours as the rhythm, so, the colony of the ants has obvious light-rhythm movement, showing that the biological clock will act on group and being controlled by light period. 本研究是在探討黑棘蟻 (polyrhachis dives) 聚落是否有生物時鐘(biological clock),以觀察黑棘蟻在巢裡的活動情形,找出週期並探討光是否會影響週期。結果觀察出黑棘蟻 的聚落在有光的時候(L:D=12:12)以23.8 小時為週期,沒有光的時候(D:D)黑棘蟻仍呈現自由律動(free running),以23.1 小時為週期,所以黑棘蟻的聚落有明顯的日週律動,顯示生物時鐘能作用在聚落上,且受光週期之調控。

咦?!田螺長毛了!探討石田螺及其螺殼上附生藻類與環境因子之關係

This research is about two ponds in the Behu park’s and the Dahu park’s snail(Square Mystery Snail:Sinotaia quadrata) in Taipei city of Nei-hu District for research object, carry out the study of the following research proceed: 1.Discriminate the algae species that are growth on the snail shell and which is a kind of interaction with the snail; 2.The influence of the snail and algae with difference of temperature, salinity, pH value and dark ; 3. The factors affect algae growth on snail shell; 4.Use the variation of snail and algae to be a biological incator. The result manifestation: the algae that are growth on snail shell have two kinds, one is Oscillatoriaceae and the other is Cladophora sp. The interaction between algae and snail belong to communalism, but under the condition of lacking of food, the snail then will eat the Cladophora sp. which grow on the shell of other snails. The temperature adapts aspect, upper limit of the feat existence of the snail should be low in 28℃. When over than 28℃, Cladophora sp. as the most strong, Oscillatoriaceae is secondly, and the snail then is most poor. For the maximum tolerance of the salinity, the snail is about 4.38?, Oscillatoriaceae is about 5.00?, Cladophora sp. is then about 5.83?; Under the different salinity for the tolerance , the Cladophora sp. still the most strong, Oscillatoriaceae is secondly, and the snail then is most poor. Under the dark environment, the speed of Oscillatoriaceae begin to be bleaching is very fast than the Cladophora sp.. In the tolerance of pH value range: The snail is about pH=5~10, Oscillatoriaceae is about pH=7~8, Cladophora sp. is about pH=6~8; When the pH value range is in the pH=5~8, the speed of the Oscillatoriaceae occur changing is very fast than Cladophora sp.. The algae are growing on snail shell very different between two ponds, the main reason is water pH value dissimilarly: When pH value over than 8.5, there is no Cladophora sp. to grow on the snail shell, after the pH value to decrease, Oscillatoriaceae then will compare early than Cladophora sp. to grow on the snail shell. Calculate by the classification of the freshwater biological incator : Two organic pollution degree of the ponds may be lain in theβ-mesosaprobic to theα-mesosaprobic, and the polluting degree of the Dahu pond is more seriously. As for two ponds, have already faced what level of eutrophication? Belong to actually which stage of pollution grade? Not only added the classification data of floating and fixative algea in two ponds, and also according to the parts of chemistry analysis method measure of the data makes the substantial evidence, then could carry out the more accurate and thorough study in the days to come steadily studying process.本研究是以臺北市內湖區兩個綠地公園(碧湖公園與大湖公園)池塘內的石田螺(Sinotaia quadrata)為研究對象,進行以下研究目的之探討:1.鑑別石田螺螺殼上藻類的種類及其與石田螺的互動關係;2.溫度、鹽度、酸鹼值及黑暗等環境因子的差異,對石田螺及螺殼上附生藻類的影響;3.影響藻類附生於石田螺螺殼上的因素;4.將石田螺及螺殼上附生藻類的變化作為監測環境因子或水質變異的指標現象。結果顯示:附生於石田螺螺殼上的藻類有顫藻(Oscillatoriaceae)與剛毛藻(Cladophora sp.)兩類;與石田螺的互動關係應屬於片利共生(communalism),但在缺乏食物的情況下,石田螺則會採食同伴殼上的剛毛藻。溫度適應方面,石田螺適宜生存的溫度上限應低於28℃,超過28℃水溫環境的耐受程度,是以剛毛藻為最強,其次是顫藻,而石田螺則為最差。對於環境鹽度最大耐受度方面:石田螺約為4.38?,顫藻約為5.00?,剛毛藻則約為5.83?;在不同鹽度環境下,鹽度的耐受程度,仍以剛毛藻為最強,其次是顫藻,而石田螺則是最差。在黑暗環境下,顫藻褪色產生白化現象的速度明顯地比剛毛藻要快了許多。在環境酸鹼值耐受的範圍方面:石田螺約在pH=5~10 之間,顫藻約在pH=7~8 之間,剛毛藻則約在pH=6~8之間;而酸鹼值範圍在pH=5~8 時,顫藻產生變化的速度明顯地比剛毛藻還要快。而兩樣區池塘水體酸鹼值的不同,應是造成石田螺螺殼藻類附生現象差異的主要原因:當酸鹼值超過8.5 時,螺殼上就無剛毛藻附生,當酸鹼值降下後,顫藻則會比剛毛藻早出現在螺殼上。藉由淡水生物指標的分類推測:兩樣區池塘水體有機污染程度,可能介於β-中腐水性(β-mesosaprobic,βm)至α-中腐水性(α-mesosaprobic,αm)的範圍之間,而D池塘受污染的程度應會比B池塘還要更嚴重些。至於兩樣區池塘水體,已面臨了何種優養化的程度?究竟是屬於哪一個階段的污染等級呢?除須補充水體中浮游性及附著性藻類分類的詳細觀察資料外,仍必須參照部分水質化學分析法所測得的數據作佐證,才能在日後持續地研究過程中進行更精確及深入的探討。

大安水蓑衣(Hygrophila pogonocalyx)的復育對黑擬蛺蝶(Junonia iphita iphita)食性偏好??

大安水蓑衣(Hygrophila pogonocalyx)為局限分佈於臺中縣沿海溼地之稀有植物。大量境外復育栽殖後,造成近年來黑擬蛺蝶(Junonia iphita iphita)利用此種新寄主植物的比例增加。本實驗比較黑擬蛺蝶在原寄主植物臺灣馬藍(Strobilanthes formosanus)及新寄主植物大安水蓑衣上之生長環境遮蔽度、幼蟲生長發育、雌蝶產卵偏好的差異,探討大安水蓑衣復育對黑擬蛺蝶族群可能造成的影響。實驗結果發現利用大安水蓑衣之幼蟲生長發育較佳、羽化後成蟲體型較大、有效積溫常數較低。雌蝶產卵行為可能存在兩種偏好性,且子代雌蝶對寄主植物的偏好性與親代一致,不受幼蟲期取食植物影響。偏好新寄主植物之雌蝶其子代的生長發育,利用新寄主植物者顯著較利用原寄主植物者佳,顯示其對原寄主植物的適應顯著下降。本研究認為大安水蓑衣的復育結果,造成黑擬蛺蝶族群在可能共域的情況下,因為利用新的寄主植物可能已產生初步分化的現象。Hypgrophila pogonocalyx is a rare plant species which is distributed in wetlands along seashore of Taichung County. Recently, I found that the common butterfly Junonia iphita iphita recognized H. pogonocalyx as a new hostplant because of the restoration practices of H. pogonocalyx. We compared the differences of forest overstory coverage, larval growth performance and female oviposition preference between J. iphita iphita individuals exploiting the H. pogonocalyx and those utilizing the original hostplant Strobilanthes formosanus. Possible effects on J. iphita iphita by restoration of H. pogonocalyx are analyzed and discussed. It turns out that better growing performance and longer adult forewing length were found on the larvae feeding on H. pogonocalyx than those on the S. formosanus. Besides, the larvae feeding on H. pogonocalyx demonstrated lower constant value of effective accumulated temperature, suggesting that the new host may provide more energy to the larvae than the original host does. Two types of female oviposition preference seem to exist. No matter which hostplant the larvae fed on, the female adults still maintained the oviposition preference of the parental generation. Offspring of H. pogonocalyx-preferring female had better performance on this new hostplant. Our studies showed that the restoration of H. pogonocalyx might have caused primary differentiation of J. iphita iphita by using new hostplant in sympatry with the original hostplant.

黑擬蛺蝶(Junonia iphita iphita)的幼蟲生存策略

黑擬蛺蝶(Junonia iphita iphita)為台灣地區常見的蛺蝶,其幼蟲具有築巢行為,但文獻中對其幼蟲行為的描述極少,因此本實驗探討黑擬蛺蝶幼蟲在野外的族群變化與環境之關係,並研究幼蟲築巢行為,以探討其適應環境的生存策略。首先於室內及恆溫生長箱中飼養幼蟲,以建立其生活史基本資料,並於野外統計各齡期幼蟲在不同植物上的數量變化及築巢行為的差異,以探討不同環境因素對幼蟲築巢之影響。由實驗結果得知,黑擬蛺蝶生活史短,可取食多種爵床科(Acanthaceae)之植物,其寄主植物除文獻所紀錄之台灣馬藍(Strobilanthes formosanus)及賽山藍(Blechum pyramudatum)等外,也取食大安水蓑衣(Hydrophila pogonocalyx)、無花水蓑衣(Hygrophila violacea)、易生木(Hemigraphis repanda)及翠蘆利(Ruellia brittoniana)等。黑擬蛺蝶幼蟲野外族群波動與溫溼度及雨量等環境因子並無直接關係。黑擬蛺蝶一年發生多世代且有世代重疊情形,世代波動與四季律動關係不明顯,顯示黑擬蛺蝶對環境的適應力大。黑擬蛺蝶幼蟲利用築巢以適應環境變化,應是其幼蟲良好的生存策略。且幼蟲在強風及光線強的環境下築巢率增加,降雨時則減少。Junonia iphita iphita belongs to Nymphalidae(Lepidoptera). They can be found easily in the wilderness of Taiwan. Its larva shows nest-making behavior. However, there is little literature documenting the behaviors of its larva. Therefore, the purpose of this research is to investigate the relationship between the quantities of Junonia iphita iphita’s larvae and its natural habitat, to research its nesting behaviors, and to investigate its survival strategies to adapt to the environment. I started by raising larvae in a growth chamber under a controlled temperature in order to obtain its initial information regarding its life history. In the field, I documented the numbers and the changes of larvae at each stage on different host plants and recorded the differences in its nest-making behavior in order to find out which environment factors influence the nest-making of Junonia iphita iphita’s larvae. These experiments concluded that the life history of larvae is short. The immature intaking habit showed that the larva takes various plants of the Acanthaceae. In addition to the host plants mentioned in the literature, such as Strobilanthes formosanus, and Blechum pyramidatum, Junonia iphita iphita’s larvae also live by Hydrophila pogonocalyx, Hygrophila violacea, Hemigraphis repanda, and Ruelba brittoniana, which were not listed in the literature. Through experiments, I discovered that there is no direct correlation between the population fluctuations of larvae and it’s enviroment including factors such as temperature, humidity or rainfall. Junonia iphita iphita can produce multi-generations in a year accompanying generation overlapping. There is also no obvious correlation between the generation fluctuations and changing seasons, showing that larvae can easily adapt to the environment. Junonia iphita iphita’s larvae adapt themselves to the different environments by nest-making which should be a good survival strategy. Besides, the rate of nest-making increases when larvae are under strong winds and strong lights and decreases when the rain falls.

「蟑」冠「裡」戴—蟑螂免疫系統之敵我辨識與記憶性等性質的探討

本研究建立蟑螂(Periplaneta Americana)之包囊作用(encapsulation)的觀察與測量方法,探討二氧化碳麻醉、植入物表面蛋白分子結構、可逆性與性別等因子,對免疫反應程度的效應,並研究敵我辨識與免疫的記憶性等特性。我們發現當異體的觸角被植入時,蟑螂體內所產生的包囊作用較自體觸角強烈,顯示具有辨識敵我的能力,且不同的生物性與非生物性植入物,所引發之包囊作用的反應程度亦不同。若分別先植入少量自體或異體組織,三日後再比較自體與異體觸角所引發的包囊作用程度,發現自體與異體組織的記憶效應不盡相同,我們證實蟑螂不但具免疫記憶性,且記憶性質具有促進性與抑制性兩種。另外我們也發現,雌蟲的免疫反應會大於雄蟲。
