Florida diatom assemblages as indicators of trophic state and pH.
, 1989 Predictive models were developed that relate lake trophic state to diatom assemblages in surface sediments. These models can be used to assess quantitatively the historical impact of cultural activities on lake productivity.

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Zooplankton and Trophic State Relationships in Florida Lakes
, 1983 Zooplankton, including ciliated protozoans, were collected from 39 Florida lakes of widely ranging trophic state. Annual mean biomass values for different zooplankton groups were regressed against Carlson's Trophic State Index based on annual mean ...

The Anatomical Record, EarlyView.Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

WATER QUALITY AND TROPHIC STATE INDEX OF THE PEQUIA WATERSHED - MA
, 2023 Monitoring water quality becomes a useful and relevant tool for planning and taking actions that guarantee water conservation. Water quality indicators are commonly used because they are easy to interpret, supporting decision-making. Therefore, the present study aims to analyze the physical-chemical and biological parameters from the Water Quality ...

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 ...

The Anatomical Record, EarlyView.Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

The Anatomical Record, EarlyView.Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...
