Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river ...


Ménage À Trois In The Atlantic Brief Squid (Lolliguncula Brevis): Prior Presence Affects Mate Choice, Rachel A. Schlessinger May 2016

Ménage À Trois In The Atlantic Brief Squid (Lolliguncula Brevis): Prior Presence Affects Mate Choice, Rachel A. Schlessinger

School of Arts & Sciences Theses

Lolliguncula brevis given prior presence experienced a significantly greater number of contacts with opposite sex squid than rivals. Males given prior presence also spent significantly more time in proximity to females than rivals. This suggests that for both female and male Atlantic brief squid, having prior presence influences mating behavior.


Factors Influencing The Choice Of A Safe Haven For Offloading Illegally Caught Fish: A Comparative Analysis Of Developed And Developing Economies, Nerea Marteache, Julie S. Viollaz, Gohar A. Petrossian Oct 2015

Factors Influencing The Choice Of A Safe Haven For Offloading Illegally Caught Fish: A Comparative Analysis Of Developed And Developing Economies, Nerea Marteache, Julie S. Viollaz, Gohar A. Petrossian

Publications and Research

Using data from 72 countries, this study focuses on factors that affect illegal, unreported, and unregulated (IUU) fishing vessels’ choice of country to offload their catch, with a specific emphasis on the differences between developed and developing economies. The concept of choice-structuring properties is applied to analyze whether the following factors influence the selection of a country: concealability of vessels and illegally caught fish; convenience of the ports; strength of fisheries monitoring, control, and surveillance measures; effectiveness of country governance; and commitment to wildlife protection regulations. Results indicate that, rather than a country’s level of development, situational factors play ...


Are Characiform Fishes Gondwanan In Origin? Insights From A Time-Scaled Molecular Phylogeny Of The Citharinoidei (Ostariophysi: Characiformes), Jairo Arroyave, John S. S. Denton, Melanie L. J. Stiassny Oct 2013

Are Characiform Fishes Gondwanan In Origin? Insights From A Time-Scaled Molecular Phylogeny Of The Citharinoidei (Ostariophysi: Characiformes), Jairo Arroyave, John S. S. Denton, Melanie L. J. Stiassny

Publications and Research

Fishes of the order Characiformes are a diverse and economically important teleost clade whose extant members are found exclusively in African and Neotropical freshwaters. Although their transatlantic distribution has been primarily attributed to the Early Cretaceous fragmentation of western Gondwana, vicariance has not been tested with temporal information beyond that contained in their fragmentary fossil record and a recent time-scaled phylogeny focused on the African family Alestidae. Because members of the suborder Citharinoidei constitute the sister lineage to the entire remaining Afro-Neotropical characiform radiation, we inferred a time-calibrated molecular phylogeny of citharinoids using a popular Bayesian approach to molecular dating ...
