Interspecific territoriality occurs when individuals of different species fight over space, and may arise spontaneously when populations of closely related territorial species first come into contact. But defence of space is costly, and unless the benefits of excluding heterospecifics exceed the costs, natural selection should favour divergence in competitor recognition until the species no lon...
Interspecific competition plays an important role in structuring ecological communities and generating patterns of phenotypic diversification. In the Shenandoah Mountains of Virginia, strong interspecific competition between P. cinereus and P. shenandoah shapes the geographic distributions of these species and relegates P. shenandoah to sub-optimal habitat. However, while many Plethodon salaman...
Assessment of the relative strengths of intra- and interspecific competition has increased in recent years and is critical to understanding the importance of competition. Yet, whether intra- and interspecific competition can have non-additive effects has rarely been tested. The resulting fitness consequences of such non-additive interactions are important to provide the context necessary to adv...
Embryonic development of lymphatics (lymphangiogenesis) in recent years has rarely been studied experimentally. Using an avian model, we showed that both intra- and extra-embryonic blood vessels of chick and quail embryos are accompanied by lymphatics. The lymphatics of the chorioallantoic membrane (CAM) are drained by lymphatic trunks of the umbilicus and are connected to the posterior lymph h...
Background: Surgical treatments of vitiligo are punch grafting, blister grafting, flip-top transplantation, split skin grafting, etc aiming at rebuilding of melanocytic population in those patients who do not respond to medical treatment . The objective of this study was determination of efficacy of blister grafting technique in the treatment of vitiligo. Methods: This study was done on 10 pati...
Bergmann’s rule—the tendency for body size to increase in colder environments—remains controversial today, despite 150 years of research. Considerable debate has revolved around whether the rule applies within or among species. However, this debate has generally not considered that clade-level relationships are caused by both intraand interspecific effects. In this article, we implement a novel...
