laryngeally-echolocating bats from all other bats. Our discovery reopens
basic questions about the timing and the origin of flight and echolocation
in the early evolution of bats.

perception where animals emit sounds and then listen to the reflected
echoes to form images of their environment in their brain. For the process
to work outgoing sounds must be represented at a neuronal level for
future comparison with returning echoes. The mechanism effecting this
neuronal representation is presently unknown. The ability to echolocate
has evolved at least four times in mammals (bats, whales, shrews,
tenrecs) and twice in birds (oilbirds and cave swiftlets). Although
echolocation is usually associated with bats, it is not characteristic of
them. Most echolocating bats emit sounds from the larynx, but within one
family of mainly non-echolocating bats (Pteropodidae), a few species
emit broadband unstructured sounds by clicking their tongue. The
diversity of echolocation is reflected in the variety of signals that bats
emit, which can include constant frequency (CF-narrowband) and/or
frequency modulated (FM-broadband) components that can be long or
short in duration and emitted in varying temporal patterns. Using
anatomical data obtained from micro-computed tomography scans of
fluid preserved bats, we found that proximal articulation of the stylohyal
bone with the tympanic bone always distinguishes laryngeallyecholocating
bats from both non-echolocating and tongue-clicking
pteropodid bats. The stylohyal bone is part of the mammalian hyoid
apparatus and functions in breathing, swallowing and phonation; the
tympanic bone surrounds and supports the tympanic membrane. In many
high duty cycle species, the stylohyal was fused at a point or along the
entire length of contact with the tympanic. A previous report on the
stylohyal in the oldest known fossil bat (Onychonycteris finneyi)
suggested that it did not echolocate; however, we speculate that O. finneyi
may have had the capacity for laryngeal echolocation because its
stylohyals may have articulated with its tympanics. A coupling of the
larynx to the ear via a stylohyal-tympanic connection could serve
multiple functions in hearing and echolocation, and provides an
independent anatomical character to distinguish laryngeally-echolocating
bats from all other bats. Our discovery reopens basic questions about the
timing and the origin of flight and echolocation in the early evolution of
bats.

(Collembola: Tomoceridae) in the Southern Appalachians
Based on Morphological and Molecular Data. Annals of

Pogonognathellus Börner is the most common genus of tomocerid
Collembola in the southern Appalachian region of the United States.
Scale pattern, cuticle color, and molecular data were used with
morphology and chaetotaxy to reappraise the members of this genus. P.
bidentatus and P. elongatus are confirmed as well-marked species; P.
nigritus Maynard is removed from synonymy with P. elongatus and

reestablished as a valid species, and a neotype is designated. Two new
species are described. Pogonognathellus danieli n. sp. from a cave in
Great Smoky Mountains National Park resembles the California cave
species P. celsus but possesses clubbed tenent hairs on all tibiotarsi; in P.
celsus, the tenent hairs are pointed. P. mystax n. sp. is related to the "P.
flavescens complex" but differs in having a purple clypeus and a
prominent band of light scales along the posterior edge of each tergite.
Many collections of P. flavescens-like and P. dubius-like specimens were
made but molecular analysis indicated that these specimens consisted of
four P. dubius-like taxa and four P. flavescens-like taxa. True P.
flavescens from Sweden (type locality) were molecularly distinct from
the putative American P. flavescens included in the analysis. A tentative
phylogenetic tree indicated three clades of southern Appalachian
Pogonognathellus: one clade containing P. bidentatus; another clade
containing species with posterior cephalic macrochaetae but without
anterior macrochaetae on the fourth abdominal tergite (Abd. IV; P.
elongatus, P. nigritus, and an undescribed species); and a third clade
without posterior cephalic macrochaetae but with one pair of anterior
macrochaetae on Abd. IV (P. danieli, P. mystax, and eight undescribed
species). KW: Appalachian Mountains, Collembola, phylogeny,

FENDRIHAN (S.), 2010. Microorganisms isolated from
subsurface environments and their importance for
astrobiology and theoretical biology. ELBA Bioflux 2(1,
July 30):23-36. ABS. Objective: the article is a review of the very
controversial microbial life in subsurface environments like caves, rocks,
mines, deep subsurface water and springs, in very special extreme
environments. Material and Methods: the methods of isolation of the
bacteria and archaea from subsurface environments are discussed too and
analysed. Results: the results of years of investigations showed the
possiblilities of adaptation to extreme environments and survival on very
long periods of times, even geological eras, of some microorganisms. The
inner biochemical, physical, biological and energetic mechanisms are still
not elucidated, even some features were discovered. Conclusion: an
extensive and intensive work of cooperation in this field of activity is
required to discover the mechanisms of long term survival in extreme
conditions of the subsurface microorganisms. KW: Subsurface
environments, astrobiology, microorganisms, extreme environments,

în revistă a controversatei probleme a vieţii microbiene în mediile
subterane cum ar fi peşterile, minele, apele subterane şi izvoarele, în
medii extreme foarte speciale. Material şi metodă: metodele de izolare a
bacteriilor şi arhaea din mediile subterane sunt discutate şi analizate în
lucrare. Rezultate: rezultatele multor ani de investigaţii arată că este
posibil ca microorganismele să se adapteze la medii extreme şi să
supravieţuiească chiar pe perioade de timp la nivelul unor ere geologice.
Mecanismul intim biochimic, fizic, biologic şi energetic este în
continuare o problemă de elucidat, chiar dacă unele elemente au fost
identificate. Concluzii: o muncă extensivă şi intensivă în cooperare, în
acest domeniu, este necesara penru descoperirea mecanismului ce permite
lunga supravieţuire în condiţii extreme a microrganismelor din mediul
subteran. CC: Medii subterane, astrobiologie, microorganisme, medii

across diverse regions of Brazil have shown a great number of new
species, many of which belong to new genera, families and even
suborders. In the last five years, at least 300 troglobiotic species were
discovered in Brazilian caves. Many of these species are highly
troglomorphic. During past decades, researchers thought that the
Neotropical region would harbor few troglobionts due to the low climatic
severity in the tropics during the glacial maxima in comparison to
temperate regions. The main model that assumes the isolation and
