THE RELATIONSHIP OF STUDENTS' UNDERSTANDING LEVEL OF ANIMAL MORPHOLOGY CHARACTERISTICS WITH THE ABILITY TO MEMORIZE ANIMAL LATIN NAMES IN GRADE 10 IPAAbstractAnimal taxonomy subjects often use animal's Latin names. Many students think that this subject is annoying because it is dominated by memorizing animal's Latin names, even though memorizing becomes a prerequisite for understanding. Meanwhile, most of the language materials memorized need an understanding before the memorizing process. This study aimed to find a relationship between the level of students' understanding of an animal's morphological characteristics and the ability to memorize animal's Latin names at the Xth grade of IPA students in SMAN 3 Jember. This study used a quantitative approach with a type of ex post facto. The test obtained the data. Then it was descriptively and inferentially analyzed by Kendall correlation. This research indicated that 56 students who answered test of the level of understanding animal's morphological characteristics and the ability to memorize animal's Latin names resulted in a correlation coefficient of score 0.673, and significance 0,000 < 0.05. Therefore, if the level of students’ understanding of an animal's morphological characteristics increased, the ability to memorize animal's Latin names at the Xth grade of IPA students in SMAN 3 Jember also increased, conversely. AbstrakNama latin hewan sering digunakan dalam materi taksonomi hewan. Banyak siswa beranggapan bahwa materi tersebut membosankan karena didominasi oleh menghafal nama latin hewan, padahal menghafal menjadi prasyarat pemahaman. Sementara itu, sebagian besar materi bahasa yang dihafal membutuhkan pemahaman sebelum proses menghafal berlangsung. Tujuan penelitian ini ialah mengetahui hubungan tingkat pemahaman karakteristik morfologi hewan dengan kemampuan menghafal nama latin hewan pada siswa kelas X IPA SMA Negeri 3 Jember. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis eks post facto. Data didapatkan menggunakan instrumen tes. Kemudian dianalisis secara deskriptif dan inferensial menggunakan korelasi Kendall. Penelitian ini menunjukkan bahwa dari 56 siswa yang menjawab tes tingkat pemahaman karakteristik morfologi hewan dan kemampuan menghafal nama latin hewan menghasilkan koefisien korelasi 0,673 dan signifikansi 0,000 < 0,05. Dengan demikian, jika tingkat pemahaman karakteristik morfologi hewan meningkat, kemampuan menghafal nama latin hewan pada siswa kelas X IPA SMA Negeri 3 Jember juga meningkat, begitupula sebaliknya.

AbstractBased mainly on an analysis of the host ranges of the species presently placed in Cactodera, sensu lato, and of selected morphological characteristics, an attempt is made to improve the definition of the genus which, after exclusion of C. betulae and C. johanseni, is considered to be monophyletic. The host range of Cactodera, sensu stricto, appears to be restricted to the subclass Caryophyllidae with the ten known species showing an adaptive radiation on host genera in five families of the orders Caryophyllales and Polygonales. This may be a result of co-evolution. Cactodera betulae cannot be assigned to any of the presently recognised genera of cyst-forming nematodes and therefore Betulodera gen. nov. is proposed with B. betulae comb. nov. as the type and only species. The relationship of Betulodera gen. nov. to other genera of Heteroderidae and to some undescribed heteroderid species has still to be evaluated. The new genus is characterised by circumfenestrate cysts with only a slightly protruding vulval cone, three incisures in the lateral field of the second-stage juveniles and presence of phasmids in the males. The hosts are in unrelated plant orders and subclasses. Cactodera aquatica, a species inquirenda, is returned to the genus Heterodera and Heterodera johanseni (Sharma et al. , 2001) comb. nov. is proposed for C. johanseni.

Bon Religion is the original religion of the Qinghai-Tibet Plateau. Today there are still Bon beliefs or cultural phenomena influenced by Bon Religion in areas where Tibetans live. This is an important content of Tibetology research today. Predecessors’ research on Bon Religion mainly focused on three major issues: the birth of Bon Religion, the historical staging of Bon Religion, and the relationship between Buddhism and Ben religion. Many results have been achieved. However, these are far from enough in terms of the research value of Bon Religion itself. The research on the time and place of the birth of Bon Religion has not yet been concluded. The main results are concentrated on the research of macroscopic issues, and the research on specific issues is insufficient. In response to these issues, researchers should pay attention to the re-discussion of existing results, use the method of combining literature and field investigations to pay more attention to specific regional issues, and at the same time strengthen the use of multiple languages.

Exchangeable cation data are presented for 97 Solonetzic and 131 Chernozemic B horizons from profiles sampled on morphological characteristics, by the Saskatchewan Soil Survey. The average exchangeable sodium percentage in the B horizons of the Calcareous, Orthic, and Eluviated Chernozems was 0.95, 1.3, and 2.6; and in the Bn horizons of the Solonetz, Solodized Solonetz, and Solod was 4.5, 9.4, and 4.0.Using the chemical criteria accepted by the National Soil Survey Committee of Canada for a n horizon (over 12% exchangeable sodium or more exchangeable sodium plus magnesium than calcium) only 28, 74, and 41% of the Solonetz, Solodized Solonetz, and Solod, as classified in the field, would remain in the Solonetzic Order. On the basis of exchangeable cations, 4% of the Orthic and 20% of the Eluviated Chernozems would fall within the Solonetzic Order because of high exchangeable magnesium.It is proposed that a Solonetzic B horizon on the basis of chemistry be one that contains more than 4% exchangeable sodium and has a ratio of exchangeable calcium to sodium of 10 or less, in order to exclude Chernozemic soils with high exchangeable magnesium from the Solonetzic Order.

ABSTRACT This study aimed to understand the relationship of morphological characteristics and actual evapotranspiration of forage cactus clones with their productive capacity under different water regimes. The data used in this study were collected between the years 2012 and 2013, in Serra Talhada, State of Pernambuco. The clones Sertânia IPA - IPA, Miúda - MIU and Orelha de Elefante Mexicana - OEM were submitted to three irrigation depths (2.5, 5.0 and 7.5 mm) and three irrigation intervals (7, 14 and 28 days). Cladode and plant morphology, accumulated actual evapotranspiration and yield were obtained at the moment of harvest. Pearson’s correlation matrix was elaborated and, in the sequence, multicollinearity, canonical and path analysis were applied. There was no correlation of yield with the soil water supply and actual evapotranspiration of the clones (p > 0.05). Forage cactus yield was more associated with peculiarities of the morphological characteristics of the clones than with the different soil water supplies or the crop actual evapotranspiration. However, regardless of the water regime and clone, the vigor of the basal cladodes was highly decisive for the expression of the forage cactus productive capacity.
