Cell shape dynamics during the staphylococcal cell cycle
Staphylococcus aureus is an aggressive pathogen and a model organism to study cell division in sequential orthogonal planes in spherical bacteria. However, the small size of staphylococcal cells hasExpand

The environmental basis of diet variation in pumpkinseed sunfish, Lepomis gibbosus, and largemouth bass, Micropterus salmoides, along an Iberian river basin
The diet composition of largemouth bass, Micropterus salmoides, and pumpkinseed sunfish, Lepomis gibbosus, and its relation to environmental factors was studied in intermittent watercourses of theExpand

Peptidoglycan synthesis drives FtsZ treadmilling-independent step of cytokinesis
Peptidoglycan is the main component of the bacterial wall and protects cells from the mechanical stress that results from high intracellular turgor. Peptidoglycan biosynthesis is very similar in allExpand

Does longitudinal connectivity loss affect the distribution of freshwater fish
Abstract Loss of natural river network connectivity is presumed to be one of the more generalized and important human-induced alterations in natural environments and is frequently perceived as one ofExpand

Regional and local environmental correlates of native Iberian fish fauna
Knowledge of fishes' habitat requirements is an essential tool for species conservation. We examined the habitat requirements of nine native freshwater fish species using 165 undisturbed or minimallyExpand

Composition of Endemic Fish Assemblages in Relation to Exotic Species and River Regulation in a Temperate Stream
Spatial variation in the fish community of the regulated Raia stream (Portugal) was examined during the summer of 1995. Variation in the native fish community (abundance of species-size combinations)Expand

Prioritizing restoration of structural connectivity in rivers: a graph based approach
We identify which barriers most impacted the structural connectivity of a river basin and which connections should preferably be restored or enhanced in order to effectively improve the overall connectivity. Expand

Assessing biotic integrity in Iberian rivers: Development of a multimetric plant index
Abstract Aquatic and riparian plant species were examined in order to propose a multimetric plant index to assess the biotic integrity in Iberian rivers. An additional analysis with two other plantExpand

Fish assemblage composition in relation to environmental gradients in Portuguese reservoirs
Abstract Patterns in fish taxa composition were examined in Portuguese reservoirs to assess whether distinct types of assemblages exist. Furthermore, the environmental variables most tightlyExpand
