The Invasive Ameiurus Nebulosus (Lesueur, 1819) As A Permanent Part Of The Fish Fauna In Selected Reservoirs In Central Europe: Long-Term Study Of Three Shallow Lakes, Jacek Rechulicz, Wojciech Plaska Jan 2018

The Invasive Ameiurus Nebulosus (Lesueur, 1819) As A Permanent Part Of The Fish Fauna In Selected Reservoirs In Central Europe: Long-Term Study Of Three Shallow Lakes, Jacek Rechulicz, Wojciech Plaska

Turkish Journal of Zoology

The invasive brown bullhead (Ameiurus nebulosus (Lesueur, 1918)) has been present in Europe since the late 19th century, but there is still a lack of reliable information about its distribution in Europe and the condition of its population. A long-term study (from 2000 to 2011) in three shallow lakes in Central Europe (eastern Poland) was carried out to determine the occurrence of the brown bullhead and its participation in the fish community. The brown bullhead was present in almost all the sampling fishing in all the lakes studied (C$_{i}$ = 72%-82%). Its mean abundance and share in the fish biomass …


Evaluating The Ecological Status Of The Introduced Nile Monitor (Varanus Niloticus) In Florida: Forecasting Presence And Population Expansion Using Computational Geographic Information Systems, Noah G. Cohen Nov 2017

Evaluating The Ecological Status Of The Introduced Nile Monitor (Varanus Niloticus) In Florida: Forecasting Presence And Population Expansion Using Computational Geographic Information Systems, Noah G. Cohen

HCNSO Student Theses and Dissertations

The Nile monitor (Varanus niloticus) is a large, carnivorous lizard that has become a notorious invasive species in Florida, USA. Initially released in the 1980s from the pet trade, the species has since established at least three breeding populations and spread throughout much of southern Florida. While current control efforts have failed to eradicate V. niloticus, it is important to attain a better understanding of its invasive dynamics to guide and inform better control strategies. In this study, available georeferenced records of V. niloticus in Florida were compiled and linked to a habitat classification map to evaluate ecotype preferences. Factored …

Papers in Herpetology

The state of Florida, USA, has more introduced herpetofauna than any other governmental region on Earth. Four species of nonnative crocodilians have been introduced to Florida (all since 1960), one of which is established. Between 2000–2014 we field-collected three nonnative crocodilians in Miami-Dade County, Florida, and one in Hendry County, Florida. We used DNA barcoding and molecular phylogenetics to determine species identification and native range origin. Also, we described diet, movement, and growth for one crocodile. Our molecular analyses illustrated that two of the crocodiles we collected are most closely related to Nile Crocodiles (Crocodylus niloticus) from South Africa, suggesting …

First Records Of Two Formerly Overlooked Ponto-Caspian Amphipods From Turkey: Echinogammarus Trichiatus (Martynov, 1932) And Dikerogammarus Villosus (Sovinsky, 1894), Tomasz Rewicz, Alicja Konopacka, Karolina Bacela Spychalska, Murat Özbek, Michal Grabowski Jan 2016

First Records Of Two Formerly Overlooked Ponto-Caspian Amphipods From Turkey: Echinogammarus Trichiatus (Martynov, 1932) And Dikerogammarus Villosus (Sovinsky, 1894), Tomasz Rewicz, Alicja Konopacka, Karolina Bacela Spychalska, Murat Özbek, Michal Grabowski

Turkish Journal of Zoology

To date, 13 species of Ponto-Caspian amphipods have been reported from the inland waters of Turkey. Two, probably overlooked species, Echinogammarus trichiatus and Dikerogammarus villosus, are here recorded for the first time from this country. Due to the atypical morphology, the identity of E. Trichiatus was also verified with molecular methods, based on the mtDNA COI barcode. Both species, along with five other co-occurring Ponto-Caspian amphipods, were collected from Lake Durusu in September 2007. Our finding reveals high diversity of amphipods in this water body. It also presents the southernmost known localities of both species, and expands the checklist of …


First Record Of The Invasive Vinegar Fly Drosophila Suzukii (Matsumura)(Diptera: Drosophilidae) From Eastern Turkey, Alper Orhan, Rafet Aslantaş, Banu Şebnem Önder, Göksel Tozlu Jan 2016

First Record Of The Invasive Vinegar Fly Drosophila Suzukii (Matsumura)(Diptera: Drosophilidae) From Eastern Turkey, Alper Orhan, Rafet Aslantaş, Banu Şebnem Önder, Göksel Tozlu

Turkish Journal of Zoology

Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) is native to East Asia and invasive on the European and American continents. The first records in both Europe and the United States were in 2008. Since that year, it has widely moved across these continents. As D. Suzukii females lay eggs in healthy ripening fruits of several species, particularly in small soft fruits and berries, the species causes agricultural damage. The soft thin-skinned fruit pest, identified as D. Suzukii, has been found in Erzurum, Turkey, where damaged strawberry crops were observed and cultured in the middle of August and September 2014. Initially, 2 …

Genetic Characterization Of The Raccoon Dog (Nyctereutes Procyonoides),An Alien Species In The Baltic Region, Algimantas Paulauskas, Loreta Griciuviene, Jana Radzijevskaja, Vaclovas Gedminas

Turkish Journal of Zoology

The raccoon dog Nyctereutes procyonoides is a newly established alien species in Europe that spread rapidly into many European countries. They were introduced into Latvia, Estonia, and Belarus. Lithuania has been colonized by immigrants from neighboring countries (Belarus and Latvia) and since 1960 the species has occupied the whole country. The data on genetic diversity of the raccoon dog are rather limited, and not all parts of the Baltic region have been covered by previous analyses. In order to compare the level of genetic diversity and describe phylogeographic patterns throughout the raccoon dog distribution in the Palearctic region, a mitochondrial …

The Ecology Of Freshwater Bivalves In The Lake Sapanca Basin, Turkey, Ertan Ercan, Özcan Gaygusuz, Ali̇ Serhan Tarkan, Martin Reichard, Carl Smith

Turkish Journal of Zoology

Despite the ecological importance and globally threatened status of freshwater bivalves, the freshwater mussel fauna of Turkey has hitherto received little attention. The aim of this study was to describe the ecology of freshwater mussels of the Lake Sapanca basin (northwest Turkey) to provide baseline data against which to measure future trends. Five native mussel species belonging to 3 genera were encountered in surveys: Anodonta cygnea, A. anatina, Unio pictorum, U. crassus, and Dreissena polymorpha. In addition, an invasive species from Asia, A. woodiana, was recorded in the region for the first time. A. cygnea and U. pictorum were the …


Invasion By The Oak Lace Bug, Corythucha Arcuata (Say) (Heteroptera: Tingidae), In Turkey, Serap Mutun, Zeycan Ceyhan, Can Sözen Jan 2009

Invasion By The Oak Lace Bug, Corythucha Arcuata (Say) (Heteroptera: Tingidae), In Turkey, Serap Mutun, Zeycan Ceyhan, Can Sözen

Turkish Journal of Zoology

Corythucha arcuata (Heteroptera: Tingidae) is an important pest species that causes severe damage to oak species by sucking up the cellular sap material and leaving its eggs on the underside of leaves. Considered a Nearctic species with a wide distribution, especially in the United States and southern Canada, it has recently been reported beyond the North American continent, specifically in Italy, Switzerland, and Turkey. Since its first report from Bolu, in 2003, the oak lace bug has rapidly dispersed throughout Turkey-to Düzce, Zonguldak, Sakarya, Kocaeli, Eskişehir, Ankara, Çankırı, and Bilecik provinces. The present study determined that the oak lace bug …


Effects Of Fire Ants (Hymenoptera: Formicidae) On Hatching Turtles And Prevalence Of Fire Ants On Sea Turtle Nesting Beaches In Florida, Craig R. Allen, Elizabeth A. Forys, Kenneth G. Rice, Daniel P. Wojcik Jan 2001

Effects Of Fire Ants (Hymenoptera: Formicidae) On Hatching Turtles And Prevalence Of Fire Ants On Sea Turtle Nesting Beaches In Florida, Craig R. Allen, Elizabeth A. Forys, Kenneth G. Rice, Daniel P. Wojcik

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Red imported fire ants (Solenopsis invicta Buren) have increasingly been observed in loggerhead (Caretta caretta L.) and green (Chelonia mydas L.) sea turtle nests in Florida, and in the nests of freshwater turtles. They may be attracted to the disturbance, mucous and moisture associated with turtle nesting and establish foraging tunnels into turtle nests shortly after egg-laying, thus increasing the vulnerability of hatchlings to fire ant predation. We conducted experiments on a freshwater turtle (Pseudemys nelsoni Carr) to determine the potential impacts of S. invicta on turtle hatchlings. Over 70% of hatchlings were killed by …
