To enter as if by invading; overrun or crowd: Each weekend, skiers invade the mountain town.
To enter and proliferate in bodily tissue, as a pathogen: Bacteria have invaded the lungs. To encroach or intrude on; violate: To make an invasion: The cancer had invaded deeply into his liver. Military to enter a country, territory, etc by military force. Botany of plants, esp weeds to become established in a place to which they are not native. Both sides tell of heroic deeds by the victors and vanquished. The battle of Cholula starts with the trend of praising of both sides.
Towards the end, when the Aztecs started to abandon the city, the Spanish kept the assault up, searching for gold and attacking anyone carrying weapons and shields. It is a shame that there was no sense gallantry by the Spanish, woman and children killed, as were the elderly who did not convert to Christianity. The Spanish plundered the dead and the living of their gold.
Aug 05, Mike Ceballos rated it really liked it. The book was slim and easy to read, but it vividly depicts the humanity of a culture so ancient and so foreign. We know that the native populations of the New World suffered terribly when European colonialists arrived, from disease, warfare, slavery and the ensuing destruction of their known world. But what an impact to read of such destruction in the first person. My heart broke to read how they were "The Broken Spears" is a classic "must-read" for anybody interested in the conquest of Mexico.
My heart broke to read how they were hungry and snatched meat from the fire before it could cook, or how the children were carried on their parents' shoulders out of the city and were excited, not knowing the full extent of the chaos around them. And the final lines of a poem written about the destruction could be mistaken for a Biblical psalm - Have you grown weary of your servants?
Are you angry with your servants O Giver of Life? As in previous works e. Gago et al. Additionally, only the earliest record was retained when multiple records were reported for the same location in different information sources. The geographical coordinates were extracted from Google Maps, and when a reservoir name was given as locality, the coordinates from the reservoir mid-point were used. Annual expansion rates within the Guadiana catchment were calculated based on the two most distant records per year.
The specimens captured in the Portuguese section of the Guadiana watershed had four pairs of barbels, dorsal fin with one spine and six soft rays, pectoral fins with a spine, and naked skin, characteristics of the family Ictaluridae. The specimens also had eyes present, adipose fin clearly separate from the caudal fin, deeply forked caudal fin, assigning them to the genus Ictalurus. All individuals had undeveloped gonads and thus it was not possible to determine their sex macroscopically. Molecular analyses provided concordant identification of the specimens as I. Of the ten sampled specimens, eight produced good quality COI sequences and the final alignment showed all sequences to be identical GenBank Accession no.
GenBank Accession nos. JF—JF; Wong et al. A mean of three records per year were registered from to , with a maximum of 9 records in Although the number of records grew regularly over the years, the number of locations was stable until , but doubled thereafter Tab. At least four introduction events within the Guadiana drainage can unambiguously be assigned to human assisted introductions because these locations are isolated by downstream dams from previously invaded areas. The third introduction event occurred around at the Garcia-Sola dam, located upstream from the Orellana dam but without any fish passage.
Number of Ictalurus punctatus records per time period in the River Guadiana drainage between the s and , collected from various information sources: literature papers and books ; angling forums; youtube. Maximum river stretch distance km invaded by Ictalurus punctatus in the Guadiana river, as a function of time. The invaded river stretch corresponds to the sum of distances between the furthest up- and downstream locations for a given year.
Forensic reconstruction of Ictalurus punctatus invasion in the Guadiana river drainage, based on online and literature records. Arrows indicate dispersal direction and the associated letter describes the probable means of dispersal A — active dispersal; H — human translocation; F — dam constructed in previously flooded area by a downstream dam. River distance in kilometers between successive locations and year of first detection for each location were given in corresponding stretch of river and location.
Detailed sources consulted for construction of I. The current work confirms the presence of the non-native channel catfish I.

As seen in other freshwater NNF within Iberian waters, the channel catfish showed a progression from a north-eastern entryway via the Ebro drainage, into the central part of the peninsula and the upper reaches of international rivers that flow into the Atlantic Ribeiro et al.
Indeed, online records by anglers suggest that I. The usefulness of fishermen records is further augmented by the relative easiness to access both past, and near real-time information on NNF occurrence and dispersal, at minimal cost. Previous work involving online angler fora records identified three potential sources of bias for this data type. First, bias due lag time between detection by fishermen and online availability Banha et al.
Second, bias on angler demographics, with higher incidence of information from younger fishermen e. Sax et al. Third, bias due to omissions for sake of secrecy, prestige, or fear that records may influence the actions of fishery management agencies Venturelli et al.

Our forensic reconstruction of I. Several studies show that channel catfish have a great dispersal ability: its movement ranges from 0. The maximum distance moved by specimens of I. This is not surprising given that these are the areas preferred by recreational fishermen Marta et al.

Significant habitat alterations that occurred in the Guadiana drainage, e. The specimens collected in Alqueva were 4 to 5 years old Appelget and Smith Jr. The ecological consequences of the arrival of the channel catfish are unpredictable, but there is potential for a very negative impact on the Guadiana river fish community, given its richness in endemic species Filipe et al. Currently, the number of NNF in the lower Guadiana equals the number of native freshwater fish, with eleven species each Ribeiro et al. In mainland Portugal, there are 20 NNF including six new species since the last inventory conducted in the late s Ribeiro et al.
Such a high establishment rate also raises concerns related to the introduction of other non-native species, particularly species that can accidentally be carried by recreational fishermen e. To conclude, we confirm the presence of I. This approach can easily be implemented for other NNF and may eventually allow the identification of areas of recurring first occurrences within a river drainage.
