  • Triops cannibalism I've never observed intra-specific predation in Triops cancriformis, and even sick and dying individuals are left alone by their tank-mates, but cancriformis will happily scavenge the remains of dead triops, even when alternative food sources are available. Triops have a short life-cycle and often die after failing to moult properly, so the survivors often have the opportunity to snack on their deceased fellows. This is my first attempt at making a soundtrack to go along with a video.

  • Spore Pachycephalosaurus Wiki Quote - Pachycephalosaurus (meaning "thick headed lizard") is a genus of pachycephalosaurid dinosaur. It lived during the Late Cretaceous Period (Maastrichtian stage) of what is now North America. Remains have been excavated in Montana, South Dakota, and Wyoming. It was an herbivorous or omnivorous creature which is only known from a single skull and a few extremely thick skull roofs. This dinosaur is monotypic, meaning the type species, P. wyomingensis, is the only known species. Pachycephalosaurus was one of the last non-avian dinosaurs before the K--T extinction event. Another dinosaur, Tylosteus of western North America, has been synonymized with Pachycephalosaurus. Like other pachycephalosaurids, Pachycephalosaurus was a bipedal omnivore with an extremely thick skull roof. It possessed long hindlimbs and small forelimbs. Pachycephalosaurus is the largest known pachycephalosaur, measuring nearly 4.5--5 meters (15 --16 ft) in length and up to 2000 kilograms (4400 lb) in weight. The thick skull domes of Pachycephalosaurus and related genera gave rise to the theory that pachycephalosaurs used their skulls in intraspecific combat. This theory has been discredited in recent years.
  • 27. Interspecific Competition Principles of Evolution, Ecology and Behavior (EEB 122) Competition among species, or interspecific competition, can have an even greater effect on selection than competition within species (intraspecific competition). This is often the case in lower density populations. Different species can have positive, neutral, or negative effects on each other's fitness, and the effect species 1 has on species 2 is not necessarily the same that 2 has on 1. The effects that cohabiting species have on each other shapes evolution the same way that selective pressures from within a species or the physical environment shapes it.

  • the white badge of the eagle owl Nocturnal species may communicate by visual signals more frequently than previously thought. In fact, such species are habitually active around sunset and sunrise, when light conditions are still suitable for visual communication. The eagle owl, Bubo bubo, territorial and courtship displays peak during the sunset and sunrise periods and involve the display of a white badge located on the throat whose reflectance properties are ***- and period-dependent. The need to convey information by visual communication in a nocturnal species may have promoted the evolution of visual signals employed at crepuscule.

  • Laughing Gull Dominance Heirarchy Establishing Domince. These two individual Laughing Gulls are in a competitive interaction to establish their place in the pecking order in the flock. Both of these individuals participated in this behavior for nearly 10 minutes with neither giving ground. Toward the end of this clip, they finally engaged in a physical confrontation. Usually, these "pecking order" interactions end quickly with no physical contact. The pecking order is a flock behavior that serves to minimize physical interations and associated injuries. Each individual eventually learns its place in the flock. In this case, the dominanant individual is not yet clearly established. Watch these birds carefully and note the various behaviors used to express dominance without physical contact, such as pecking at the sand, a displacement behavior to avoid pecking at each other. Note the posturing, the distance between them, the orientation to each other etc. Birdwatching is more than just IDing a bird. These activities are what makes birdwatching so very interesting. Also note that the nearby birds seem to be indifferent to this activity.

  • Rafael Arevalo - Botany 2010 Who's a Mormolyca? A first look at the recircumscription of this orchid genus. Co-author: Kenneth M. Cameron Based on phylogenetic ***yses of molecular data, a new classification for the Neotropical orchid subtribe Maxillariinae has been proposed by Blanco et al. (2007). New realignments recognize 17 genera, including a recircumscribed Mormolyca Fenzl. Species of Chrysocycnis, Cyrtoglottis, and Maxillaria section Rufescens are now embedded within Mormolyca, expanding the genus from eight to approximately 25 species. However, morphological characterization of this new concept of Mormolyca is challenging, and not only were few species included in the original ***yses, but new species have been described recently. For these reasons, a thorough taxonomic revision of the genus is mandated. We are testing the monophyly of this expanded concept of Mormolyca by reconstructing the phylogeny of the group using data derived from DNA sequences, together with morphological and anatomical characters. In this first part of the study, the phylogenetic relationships among species of Mormolyca have been examined using 20 ingroup samples and seven outgroup taxa, and using sequence data from four DNA regions: the nuclear ribosomal internal transcribed spacers (ITS), plastid matK gene and flanking trnK intron, atpB-rbcL intergeneric spacer and ycf1. The monophyly of the genus, intraspecific relationships, and distribution of morphological and ecological characters is discussed. Future ...
  • Evolution Pie by The Nodes of Ranvier A Long long time ago A certain species had a few mutations And with these adaptions They knew they'd have their chance To live a couple billion years or a while But adaptation made me shiver With every base change that occurred Antibiotic resistant Bacterium were persistent I can't remember if I cried When I heard the peppered moth died But the adaptations really flied It actually survived Bye bye unadapted species Driven to extinction but we have fossil records And new adaptions replace old, saying This'll be the day I won't die, this'll be the day I won't die. The location can support A certain number of every sort If the text book tells you so But populations will over produce Increased survival is the excuse Even though the food and space are low Well they know that this creates a problem 'cause there ain't enough food and space to share This creates a struggle And the best adapted survive They were a population of organisms that existed in certain ecosystems But some of them were out of luck The day the unadaptive died Bye bye unadapted species Driven to extinction but we have fossil records And new adaptions replace old, saying This'll be the day I won't die, this'll be the day I won't die. now animals trying to make it on their own will reproduce exponentially but sadly not all will live because the population had increased the environment could not compete with lack of food and lack of space animals with good adaptions who are better suited for thier environment ...
