in such habitats is unpredictable. Cases of putative sink populations are<br />
known among stygobites observed in peripheral habitats such as<br />
intermittent pools fed by seeps in the vadose zone of caves (e. g.,<br />
Stygobromus emarginatus amphipods in Organ Cave, USA; Ituglanis<br />
epikarstikus catfish in rimstone pools in Sao Mateus Cave, Brazil). Other<br />
examples include stygobitic Trichomycterus catfish in Lapa do Peixe,<br />
Brazil (source population is somewhere else in the cave system) and nontroglomorphic<br />
Aegla decapods in Barra Bonita Cave, Brazil (source<br />
population in epigean streams). When applied to the Schiner-Racovitza<br />
classification, this conceptualization leads to clearer and biologically<br />
meaningful definitions of the three categories classically recognized: 1.<br />
troglobites (stygobites) correspond to exclusively subterranean source<br />
populations, with sink populations possibly found in surface habitats; 2.<br />
troglophiles (stygophiles) include source populations both in hypogean<br />
and epigean habitats, with individuals regularly commuting between<br />
these habitats, promoting the introgression of genes selected under<br />
epigean regimes into subterranean populations (and vice-versa); 3.<br />
trogloxenes (stygoxenes) are instances of source populations in epigean<br />
habitats, but using subterranean resources (in the so-called obligatory<br />
trogloxenes, all individuals are dependent on both surface and<br />
subterranean resources). Sink populations do not fit the Schiner-<br />
Racovitza scheme, unless one considers stranded troglobitic or stygobitic<br />
individuals as part of the subterranean source population from which they<br />
originated (e. g., the above mentioned Ituglanis and Trichomycterus<br />
catfishes). http://www.icsb<strong>2010</strong>.net/<br />

ICSB <strong>2010</strong> Abstract Book, edited by: Ajda MOŠKRIČ and<br />
Peter TRONTELJ, ISBN 978-961-269-286-5. ABS: The<br />
Brazilian subterranean ichthyofauna includes the largest number of<br />
species investigated with focus on rhythmicity. So far, 11 among 26<br />
troglomorphic fishes have been studied under free-running conditions<br />
(DD) and light-dark cycles (LD 12:12 h): the characid Stygichthys<br />
typhlops and, among catfishes, the heptapterids Pimelodella kronei, P.<br />
spelaea, Rhamdia enfurnada and three Rhamdiopsis spp., the<br />
trichomycterids Trichomycterus itacarambiensis and two Trichomycterus<br />
spp., and the callichthyid Aspidoras sp. Regression of mechanisms of<br />
time control of the locomotor activity has been shown for all studied<br />
fishes, in a lower or higher degree paralleling that of reduction of eyes<br />
and pigmentation. Individuals of highly troglomorphic species, such as S.<br />
typhlops and Rhamdiopsis sp. from Campo Formoso, were arrhythmic<br />
under free-running conditions, whereas in less troglomorphic fishes (e. g.,<br />

R. enfurnada, P. spelaea, P. kronei, Rhamdiopsis from Salitre Cave) part<br />
of the individuals retained significant circadian rhythms; interestingly,<br />
larger (probably older) individuals tend to present weaker rhythms. In<br />
general, the activity peaks were observed in the dark phases, indicating<br />
that these peaks correspond to a character state retained from the<br />
nocturnal ancestors. When submitted to LD cycles, locomotor activity<br />
was entrained in all studied individuals, except for S. typhlops fish (most<br />
specimens did not respond to this condition). Individual variation<br />
regarding the presence (or not) of residual oscillations when the fish<br />
returned to free-running conditions was observed in the studied species<br />
except for the highly specialized S. typhlops and Rhamdiopsis sp. The<br />
absence of such oscillations indicates a masking effect of LD cycles. Data<br />
on subterranean fishes provide good evidence for the hypothesis of<br />
evolutionary regression of time-control mechanisms involved in<br />
locomotor activity in troglobitic organisms, either affecting the<br />
oscillator(s) itself or due to uncoupling of the oscillator and its related<br />
function(s), supporting the hypothesis of external, ecological selection of<br />
circadian rhythms. http://www.icsb<strong>2010</strong>.net/<br />

978-961-269-286-5. ABS: Species of Pimelodella and Rhamdia<br />
have adjacent placements within the Heptapteridae phylogeny, and are<br />
similar in general appearance, distribution and habitat preferences and<br />
food habitats - species of both genera are generalist carnivores, with<br />
Rhamdia tending to be more benthonic, reaching larger sizes and<br />
incorporating fish in their diet. Ecological studies on the Brazilian<br />
troglobitic P. kronei and R. enfurnada did not reveal any differences<br />
which could not be attributed to habitat specificities. However, important<br />
behavioral differences were observed in laboratory. Chronobiological<br />
studies indicated that, in aquaria, P. kronei exhibits higher levels of<br />
spontaneous activity, with shorter intervals without detectable locomotor<br />
activity (less than 30 min.), whereas R. enfurnada may remain stationary<br />
for hours; this may reflect differences in the epigean ancestors since large<br />
Rhamdia catfishes are sit-and-wait predators. P. kronei presents more<br />
organized and distinctive, therefore predictable, patterns of chemical<br />
communication at distance, more clearly related to size and sex (small<br />
individuals generally avoid water from cospecifics, larger males are<br />
usually attracted) than in R. enfurnada, in which reaction to cospecifics<br />
varied from indifference to attraction; when detected, such responses<br />
were delayed in relation to the observed for P. kronei, possibly as a<br />
correlate to the lower activity levels in R. enfurnada. A new<br />
troglomorphic Rhamdia species from Bodoquena karst area, NW Brazil,<br />
also studied, was intermediate in these aspects. Likewise, patterns of<br />
aggressiveness are distinct. Agonistic interactions are more frequent in P.<br />
kronei and include a richer behavioral repertoire, not leading directly to<br />
death, indicating a ritualized behavior. In opposition, such interactions,<br />
rarely observed in R. enfurnada kept in groups, are less defined but, when<br />
occurring (usually among larger individuals), they lead rapidly to<br />
casualties. http://www.icsb<strong>2010</strong>.net/<br />
