Ecological impact of inland fish introduced to the Iberian Peninsula

Rotation of the iberian peninsula.

Jones and Ewing (1) have presented seismic profiler data from the Bay of Biscay which allows a 120 anticlockwise rotation of the Iberian peninsula between Eocene and Middle to Upper Miocene times. They refer several times to the fact that this va'ue is appreciably less than a rotation of 220, which they believe resulted from our paleomagnetic study of the Lisbon Volcanics (2). We must point out...

Diversity of introduced terrestrial flatworms in the Iberian Peninsula: a cautionary tale

Many tropical terrestrial planarians (Platyhelminthes, Geoplanidae) have been introduced around the globe. One of these species is known to cause significant decline in earthworm populations, resulting in a reduction of ecological functions that earthworms provide. Flatworms, additionally, are a potential risk to other species that have the same dietary needs. Hence, the planarian invasion migh...

Homogenization dynamics and introduction routes of invasive freshwater fish in the Iberian Peninsula.

Nonnative invasive species are one of the main global threats to biodiversity. The understanding of the traits characterizing successful invaders and invasion-prone ecosystems is increasing, but our predictive ability is still limited. Quantitative information on biotic homogenization and particularly its temporal dynamics is even scarcer. We used freshwater fish distribution data in the Iberia...

Ecological niche segregation among five toothed whale species off the NW Iberian Peninsula using ecological tracers as multi-approach

the impact of morphological awareness on the vocabulary development of the iranian efl students

this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
