This document summarizes a study that compiled an updated checklist of 337 species of decapod crustaceans found in the marine and estuarine environments of Ceará, Brazil. These species were identified using previous records and collections, as well as new sampling between 2011-2014. Twenty-three species, including shrimp, ghost shrimp, and crab species, represent new records for Ceará. One newly recorded shrimp, Lysmata lipkei, was previously only known from Japan, indicating potential invasion of the southwestern Atlantic Ocean. While species richness of Ceará decapods is high and comparable to other areas, further sampling is needed of subtidal zones to obtain a more complete understanding of the fauna
Puffer fish belonging to the family tetraodontidae are usually distributed in the shallow waters. During investigation in stations viz. Marina Park, Chidiyatapu and Burmanullah, around Andaman, five species from genus Arothron and two from Canthigaster have been recorded and were mostly found to prefer coral reefs and rock crevices, with the exception of Arothron immaculatus, which was found to be present in the open waters and it confined to sandy bottom substrate with patches of sea grasses around them. These fishes were found to be most diverse and abundant in Chidiyatapu with the Margelef’s Richness Index of 2.49, Shannon-Wiener index of 1.05 and Pielou’s evenness index of 0.96. Biometric analysis results demonstrate that they have shown an isometric growth. The individuals collected were mostly lying in the length group of 120-160 mm. Gut content analysis of A. Immaculatus reveals that the fish feed mainly on molluscs and sea urchin and the other food items were shrimps, crabs, sponges, micro algae, foraminiferans etc. gastro-somatic index, hepato-somatic index and gonado-somatic indices were also calculated to throw light upon the feeding behavior and reproductive maturity of the fishes. Most of the individuals were found to be in the developing stage of maturity.
The culture of maintenance ornamental fish among Iranian people is developing every day. One of the most important factors in selection aquarium fish is behavior of feeding. The feeding behavior of Guppy is poorly documented. In this experiment we study feeding behavior in P. reticulata by six treatments. Six aquariums with the same dimension were used and two points A & B with the maximum distance from each other were selected in each aquarium. In aquarium No.1 hand move with feeding in point A, in aquarium No.2 hand move without feeding in point A, in aquarium No.3 hand moves in point A and feeding in point B, in aquarium No.4 feeding without hand move in point B, in aquarium No.5 in semi dark conditions hand move with feeding in point A and finally in aquarium No.6 in darkness conditions hand move with feeding in point A were done. In aquarium No.1, 94% of fish moved to point A and in aquarium No.2 it was about 92%. In aquarium No.3, 95.5% of fish moved to point A and in Aquarium No.4, 74.5% of fish moved to point B. In aquarium No 5 and 6, 96% and 99.5% of fish moved and didn’t move to point A, respectively. Our results showed that this species is a visual feeder and a good aquarium fish for their feeding behavior.

Diversity and dispersion patterns of echinoderms in Babanlagan, Talisayan, Mi...Angelo Mark Walag
Echinoderms are fundamentally good indicators of health and status of coralline communities in marine waters. In this study, the diversity and distribution of echinoderm species were determined in Babanlagan, Talisayan, Misamis Oriental. In total, 387 individuals were collected coming from classes Echinoidea, Holothuroidea, Asteroidea, and Ophiuroidea. The majority of individuals collected were Protoreaster nodusus, which is a good indicator of reef health while the least abundant echinoderm species was Acanthaster planci. The pattern of distribution of majority of echinoderms was a clumped distribution while the other groups followed regular/uniform distribution, which may be due to limited dispersal ability and availability and available food sources. Moderate species diversity was also observed and species were rather similar in abundance, shown by the evenness index. This suggests good marine health, even under the threat of gleaning activities, active fishing, and habitat destruction. It is recommended that follow-up studies are conducted especially regarding monitoring of echinoderm species, to further assess the health of the intertidal zone in Babanlagan, Talisayan, Misamis Oriental.
Diversity and distribution of seaweeds in Saint Martin Island, BangladeshAbdullaAlAsif1
This present investigation conducted on diversity and distribution analysis of the sub-littoral seaweed flora collected from January to June, 2007 from north part and south part of the Saint Martin Island, Bangladesh has revealed the presence of 37 seaweed taxa, 11 under Chlorophyceae, 14 under Phaeophyceae and 12 under Rhodophyceae. The distribution, diversity and abundance of seaweed flora fluctuate due to temperature, locations and species composition variations in Saint Martin Island.
Snapper shrimp is a symbiotic organism usually hidden under the rocks, sponges and pen shells in the seagrass and coral habitats. The relationship study within snapper shrimp and pen shell was conducted from Merambong shoal, one of the biggest seagrass beds in peninsular Malaysia. A total of 40 individual pen shells were collected randomly and four species of pen shells were identified. 40 Anchistus custoides were found inhabiting symbiotically in the mantle cavity of the pen shell as solitary males and females and heterosexual pairs. Pen shell, Pinna bicolour and Atrina vexillum recorded the highest average SH 217.79±53.15 mm, SV 2.62±1.36 dm3 and SH 164.10-224.78 mm with the SV 1.18±0.43 dm3, respectively compared to the other species. The size of Anchistus custoides ranged from 15.00 to 20.00 mm in length and it was determined to be female due to the presence of eggs in the pleopods. The length of the cephalothorax and its length were highly related (rs=0.563, p≤0.01, N=40) and found wider in females. A little difference in size between the left and right chela in males of identical length was noticed, although the left chela is much bigger than the right. The significant relationship (rs=0.450, p≤0.01, N=40) between the pen shell length and shrimp (male-female) length revealed that the size of the shell is important to be hosted the snapper shrimp in the shell cavity.

Diversity and distribution of anuran in two islands of Parnaíba River Delta, ...Innspub Net
The distribution and composition of communities are influenced by factors that determine the environmental characteristics in a particular region. In order to obtain more information regarding the fauna of frogs in the region of the Parnaíba River Delta, Northeastern Brazil, we performed a quantitative ecological study to compare the composition and distribution of the amphibian communities. The study was conducted in the two largest islands of Deltafrom September 2008 to August 2009. Fifteen ponds were selected and slowly covered in search of males in calling activity. We recorded 21 frog species, distributed in five families and 11 genera. Ilha Grande de Santa Isabel(21 spp.) had higher species richness than the Ilha das Canárias (11 spp.). Although most species are considered to be common in open areas, they were highly influenced by the structural complexity of the vegetation. The highest richness was observed in environments with greatest availability of microhabitats for reproduction. The preservation of different environments found in the two islands, associated with the maintenance of suitable habitats for reproduction of each species, will contribute to the conservation of amphibian communities of the Parnaiba Delta River.

Diversity and Selection of Shell of the Hermit Crab of Mandvi, Kachchh Coast,...SorathiyaVasim
Made a project Diversity and Selection of Shell of the Hermit Crab. The present study concludes that both -. infraspinatus and D. Species showed marked shell utilization in the fully muddy shoreline of the west coast of India depending on their body size and the availability of preferred shell. However, -. infraspinatus was rather choosy in the selection of the shell as it resided in the shell of fewer gastropod species than D. Species. It is possible that because D. Species was the dominant species of this coastline, the interspecific competition restricted -. infraspinatus from occupying greater verities of shells. Various other factors like availability of appropriate shell, shell morphology, intraspecific and interspecific competition, seasonal effect and prior experience of the shell species may also be responsible forshell utilization preference of the hermit crab species.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.

Marine and estuarine decapod crustaceans from Ceará,
northeast Brazil
The evaluation of world’s biodiversity has always been of major concern, especially when
undertaking conservation measures or establishing protected areas. Species lists play an important
role in this context, not only providing tools for conservation purposes, but also serving as source
for several types of research. In the Atlantic side of South America, Brazil has the longest coastline
and a great variety of habitats, being of major biodiversity importance for the southwest Atlantic
marine and estuarine fauna.
Fig. 1. Map of the State of Ceará, northeast Brazil, showing sampling sites (A-H) visited between
2011 and 2014.
The Brazilian coast is divided into 17 states. One of them, the State of Ceará in the northeast
region of the country, is characterized by 578 km of coastline with extensive sandy beaches,
occasionally interrupted by arenitic rocky formations, but also several estuarine areas, typically
dominated by mangroves. In these areas, a quite diverse, although still little known invertebrate
fauna can be found. The decapod crustaceans from Ceará started to be best studied between the

late 1960’s and early 1980’s through several preliminary lists by a local researcher, Dr José
Fausto Filho. Apart from these lists, occasional new records and species have been published for
the area. Despite the number of contributions to the decapod fauna of Ceará, there have been no
attempts to review the total diversity of the marine and estuarine species. In this sense, the present
study consists of the most complete and fully updated checklist of the marine and estuarine
decapod crustaceans from the State of Ceará, which, we hope, will be valuable for conservation
and biodiversity related projects and also stimulates further ecological, taxonomic and
biogeographic research. The list was compiled using three different sources: (1) previous species
records and lists present in the literature; (2) examination of material deposited in local
carcinological collections; and (3) fresh material collected along the coast between 2011 and 2014.
A total of 337 species of decapod crustaceans are now listed from Ceará, distributed in the
following taxa: Brachyura (162 species), Caridea (83 species), Anomura (42 species),
Dendroranchiata (20 species), Axiidea (11 species), Gebiidea (9 species), Achelata (8 species),
Astacidea (1 species) and Stenopodidea (1 species). Among these, 23 species are recorded for
the first time for Ceará, including shrimps, ghost shrimps and crabs. One of the new records, the
peppermint shrimp Lysmata lipkei Okuno & Fiedler, 2010 (Caridea: Lysmatidae), was previously
known only from several islands of Japan, thus its presence in Brazil possibly indicates the species
invaded the southwestern Atlantic Ocean.

Axianassa australis Rodrigues & Shimizu, 1992; E, Lepidophthalmus siriboia Felder & Rodrigues,
1993; and F, Pilumnus reticulatus Stimpson, 1860.
The species richness of the decapod fauna from Ceará (337 species) is fairly high and comparable
to that of other Brazilian states. For instance, Ceará harbors about 60% of the total diversity of
brachyuran crabs (162 out of 272 species) and shrimp-like decapods, i.e. Dendrobranchiata,
Caridea and Stenopodidea (103 out of 169 species) currently known for the Brazilian North and
North-East. Although the list presents a high number of species, it is important to note the
predominance of intertidal species, which reflects a more extensive exploration of the intertidal
zone compared to the subtidal zone, the latter known to present a quite different fauna. Therefore,
additional collecting efforts in subtidal areas are necessary to find more species and have a more
complete idea of the decapod fauna from Ceará.
