SYNOPSIS Little attention has been paid to the suprageneric classification for conodonts and existing schemes have been formulated without attention to homology, diagnosis and definition. We propose that cladisticsprovidesanappropriatemethodology to test existing schemesof classification and in which to explore the evolutionary relationships of conodonts. The development of a multielement taxon...
Kurangnya minat belajar siswa dapat dipengaruhi oleh beberapa faktor, salah satunya adalah kurangnya media pembelajaran. Teknologi Augmented Reality merupakan teknologi yang memberikan pengalaman berbeda dengan menampilkan visual dalam bentuk 3D. Penelitian ini bertujuan untuk membangun aplikasi klasifikasi hewan vertebrata menggunakan Marker Based dan mengukur efektivitas terhadap pembelajaran...
Msx (/msh) family genes encode homeodomain (HD) proteins that control ontogeny in many animal species. We compared the structures of Msx genes from a wide range of Metazoa (Porifera, Cnidaria, Nematoda, Arthropoda, Tardigrada, Platyhelminthes, Mollusca, Brachiopoda, Annelida, Echiura, Echinodermata, Hemichordata, and Chordata) to gain an understanding of the role of these genes in phylogeny. Ex...
Extreme weather events can provide unique opportunities for testing models that predict the effect of climate change. Droughts of increasing severity have been predicted under numerous models, thus contemporary droughts may allow us to test these models prior to the onset of the more extreme effects predicted with a changing climate. In the third year of an ongoing severe drought, surveys faile...
Animal body temperature (Tbody) varies over daily and annual cycles, affecting multiple aspects of biological performance in both endothermic and ectothermic animals. Yet a comprehensive comparison of thermal performance among animals varying in Tbody (mean and variance) and heat production is lacking. Thus, we examined the thermal sensitivity of immune function (a crucial fitness determinant) ...
