Hatching asynchrony, survival, and the fitness of alternative adult morphs in \u3ci\u3eAmbystoma talpoideum\u3c/i\u3e [PDF]

, 2004
The mole salamander, Ambystoma talpoideum, exhibits both aquatic (gilled) and terrestrial (metamorphosed) adult morphologies. Previous studies have shown the existence of body-size advantages associated with the terrestrial morph in A.

A Multivariate Moran Process with Lotka-Volterra Phenomenology

, 2011
For a population with any given number of types, we construct a new multivariate Moran process with frequency-dependent selection and establish, analytically, a correspondence to equilibrium Lotka-Volterra phenomenology.

Effects of nutrient enrichment on seagrass population dynamics: evidence and synthesis from the biomass-density relationships [PDF]

, 2013
The available data from experimental and descriptive studies on seagrass biomass and density responses to nutrient enrichment were analysed to assess the intraspecific mechanisms operating within seagrass populations and whether biomass-density ...

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

The Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

The Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Bipolar patterns of intraspecific competition in bryozoans [PDF]

Marine Ecology Progress Series, 2005
Polar shores probably represent the most dynamic and extremely disturbed environ- ments on the globe. Nevertheless intense battles amongst sessile organisms for space are common- place on hard substrata, mainly between fast-growing pioneer species. In this study we examined spatial interactions in encrusting species at 3 sites within each of 2 high ...

Business Agglomeration-Based Decision Support Systems to Identify Prospective Locations for New Businesses [PDF]

, 2013
Selecting the right location when establishing new business firm is one imperative key to a successful growth of an establishment. Additionally, previous studies have also found that business firms form business agglomerations that enable these ...

Intraspecific Competition Effects on Aethina tumida (Coleoptera: Nitidulidae) [PDF]

Journal of Economic Entomology, 2012
Two kinds of experiments were conducted with Aethina tumida Murray larvae over four temperatures: "consumption" experiments, in which larvae and diet were weighed to determine food consumption rates under conditions of unlimited food and few conspecifics; and "competition" experiments, in which varying numbers of larvae were presented with the same ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Effects of intraspecific competition on the larval development and pupal weight of Dacini (Diptera : Tephritidae) infesting cucurbits in la Reunion [PDF]

, 2010
Background. In La Réunion, cucurbit crops suffer considerable damage due to fruit fly attacks. A complex of three species (The Melon fly, Bactrocera cucurbitae, The Ethiopian fly, Dacus ciliatus, and the Indian Ocean fruit fly, Dacus demmerezi) coexist ...
