TRONTELJ, ISBN 978-961-269-286-5. ABS: Troglodrilus<br />
galarzai (Giani & Rodriguez, 1988) is a stygobiont oligochaete species<br />
(Tubificinae, Clitellata, Annelida) in a monospecific genus. Its<br />
geographical distribution appears restricted to the south western Europe,<br />
and the populations known up to date occupy two well separated regions,<br />
namely northern Iberian Peninsula (Ereñozar and Gorbeia karstic units)<br />
and south eastern France (gallery of Montgelas and Crotot cave). A<br />
previous morphological study revealed some morphological differences<br />
between Iberian and French populations but concluded that they were not<br />
substantial to separate two species. More recently, we conducted a<br />
molecular analysis of two populations of the species (Gorbeia and<br />
Montgelas) using 16S rDNA and COI gene sequences and we have<br />
combined these results with a new detailed morphological analysis of all<br />
known populations. The obtained genetic distances between Gorbeia and<br />
Montgelas populations were 17.8-18.1% for COI sequences and 9.2-10%<br />
for 16S sequences, which together with mutual exclusivity of the<br />
haplotypes, supported the hypothesis of the presence of two cryptic<br />
species in T. galarzai. The new morphological study is mainly based on<br />
the reproductive system and grouped together Ereñozar + Gorbeia<br />
populations and Montgelas + Crotot populations. We found no overlap<br />
between Iberian and French populations for some measurements related<br />
with the penial sac and the spermathecal bulb, as well as key differences<br />
on the shape of the penial sheath between French and Spanish<br />
populations. Considering both the molecular results and the differences<br />
on the morphological characters between Iberian and French populations,<br />
we suggest the presence of two species in T. galarzai.<br />

Background: A major goal in evolutionary biology is to understand the<br />
evolution of phenotypic diversity. Both natural and sexual selection play<br />
a large role in generating phenotypic adaptations, with biomechanical<br />
requirements and developmental mechanisms mediating patterns of<br />
phenotypic evolution. For many traits, the relative importance of selective<br />
and developmental components remains understudied. Results: We<br />
investigated ontogenetic trajectories of foot morphology in the eight<br />
species of European plethodontid cave salamander to test the hypothesis<br />
that adult foot morphology was adapted for climbing. Using geometric<br />
morphometrics and other approaches, we found that developmental<br />
patterns in five species displayed little morphological change during<br />
growth (isometry), where the extensive interdigital webbing in adults was<br />
best explained as the retention of the juvenile morphological state. By<br />
contrast, three species exhibited significant allometry, with an increase in<br />
interdigital webbing during growth. Phylogenetic analyses revealed that<br />
multiple evolutionary transitions between isometry and allometry of foot<br />
webbing have occurred in this lineage. Allometric parameters of foot<br />
growth were most similar to those of a tropical species previously shown<br />
to be adapted for climbing. Finally, interspecific variation in adult foot<br />
morphology was significantly reduced as compared to variation among<br />
juveniles, indicating that ontogenetic convergence had resulted in a<br />
common adult foot morphology across species. Conclusions: The results<br />
presented here provide evidence of a complex history of phenotypic<br />
evolution in this clade. The common adult phenotype exhibited among<br />
species reveals that selection plays an important part in generating<br />
patterns of foot diversity in the group. However, developmental<br />
trajectories arriving at this common morphology are distinct; with some<br />
species displaying developmental stasis (isometry), while others show an<br />
increase in foot webbing during growth. Thus, multiple developmental<br />
solutions exist to the same evolutionary challenge. Our findings<br />
underscore the importance of examining morphological adaptations from<br />
multiple perspectives, and emphasize that both selective hypotheses and<br />

978-961-269-286-5. ABS: Eye degeneration is a general<br />
evolutionary tendency shown in many animal groups that are adapted to<br />
dark environments. Inside the Hoti Cave located in the Jabal Akhdar<br />
mountains in Oman lies a subterranean lake, which is home to the blind<br />
fish Garra barreimiae. Outside the cave, Garra barreimiae is a common<br />
species of eyed epigean surface fish. The eyes of the blind cave fish and<br />
of its epigean ancestor have been studied comparatively. The eye<br />
structure of the surface fish is a typical teleost eye. Parts of the eye of the<br />
cave fish show hypertrophy. Individuals compensate the lack of a lens in<br />
various ways with extreme growth of different parts of the eye. For<br />
instance, the anterior eye chamber is often filled out with a derivative of<br />
the annular ligament, and as a result the pupil no longer transmits light.<br />
The eye rudiment of the Garra barreimiae is not sunken in the orbit as is<br />
the case with other cave fish species. From these examples we can<br />
conclude that the adult cave fish population is very heterogeneous with<br />
regard to the size and structure of the eye rudiment. To understand how<br />
this diversity evolves, the ontogenetic eye development was investigated.<br />
During early ontogeny the differentiation of the eye of hypogean Garra<br />
barreimiae is similar to the epigean one. All major structures are present.<br />
However, the lens remains in the embryonic stage, and no lens<br />
differentiation occurs. It disappears altogether at the age of three months.<br />
Initially there is a complete laminated retina with typical opsin expression<br />
in the photoreceptor cells. But opsin expression remains at a low level<br />
and ceases at the age of four months. On the other hand, other retinal<br />
strata like the amacrine cell layer are well differentiated in juvenile cave<br />
Garra and remain functional for longer than the photoreceptor cells. In<br />
adult animals, on the other hand, no evidence of functional retina cells<br />
could be detected. http://www.icsb<strong>2010</strong>.net/<br />

380 p. ABS: Brazilian bats, though not much known, are already<br />
threatened due to habitat destruction. Lonchophylla dekeyseri is an<br />
endemic nectarivorous bat that occurs in low density in caverns and holes<br />
in forested and more open vegetation physiognomies of the Cerrado<br />
biome. This characteristic makes the species extremely sensitive to the<br />
loss and degradation of its habitat. Deforestation for agricultural and<br />
cattle expansion, coal-pit, construction of dams, mining and forest fires<br />
represents the most critical threats. At present, the ecological tourism,<br />
especially the speleological, can represent a significant threat. L.<br />
dekeyseri population is estimated at circa of 2070 bats, all in the wild and<br />
none in captivity. There are confirmed records for L. dekeyseri in 23<br />
Brazilian localities. Like other nectarivorous bats, the reproductive<br />
system is polygenic, with many females and few adult males. An action<br />
plan for the conservation of L. dekeyseri was concluded, composed of 10<br />
basic actions including from activities of immediate implementation, such<br />
as the environmental monitoring of the species' occurrence areas, to the<br />
implementation of mid-term activities (e. g. the creation of supplementary<br />
protected areas), and to long term activities, such as the realization of<br />
environmental education and the development of new studies on<br />
population dynamics. Suggested actions also includes the recuperation of<br />
degraded areas, control of hematofagous bats, control of cave visitation,<br />
the environmental management of vegetation remnants, and the increase<br />
of both the number of environmentally protected units and of new<br />
inventories in the data gap regions. In the existing protected areas, there is<br />
a need for research on the species' ecology, using telemetry and<br />
population genetics, as well as the management of the already altered<br />
environments in such areas. Environmental education activities are
