Subject: Nesting activity of the predatory wasp, Carinostigmus costatus Krombein (Sphecidae: Hymenoptera) in pithy stems of Caesalpinia pulcherrima (L.) and its natural regulation of the population of fennel aphid, Hyadaphis coriandri (Das)
Keywords: Aphid predation, Carinostigmus costatus, Hyadaphis coriandri, nesting activity.
Abstract: The predation of aphid hunting wasp, Carinostigmus
sp. on fennel aphid, Hyadaphis coriandri is reported
from India. The solitary wasp was molecularly identified as Carinostigmus costatus (NCBI Accession No.
OQ913733.1). The wasp constructed its nest in the pithy
stems of Ceasalpinia pulcherrima (peacock flower) provisioning fennel aphid, H. coriandri. There was a decrease
in the population of the fennel aphid, H. coriandri with
an increase in the nesting activity of the solitary wasp,
C. costatus. Our study indicated that the solitary wasp,
C. costatus could be easily conserved by providing
pithy stems of C. pulcherrima as nesting habitats around
the field borders for natural regulation of aphid infesting fennel.

Subject: The Beas river floods 2023: a watershed moment for paradigm shift towards urbanization and development in the Higher Himalayan valleys
Keywords: Alluvial deposits, anthropogenic intervention, Beas river flood, higher Himalaya, Indian Summer Monsoon.
Abstract: The present study is done in the Beas river (Manali to
Mandi town) after the July 2023 flood to assess the geomorphic and geological vulnerability of the terrain
and understand the role of human intervention in the
disaster. The study is based on preliminary field observations and morphometric analysis that indicates that
the surfaces proximal to the trunk riverbed and the
ephemeral tributary channels suffered maximum damage. Along the upper Beas river, the lateral erosion
caused by hyperconcentrated flows saturated with
paraglacial sediments partly obstructed the river and
also increased the erosivity that also led to remobilization of midchannel bars along with the uprooted trees.
In the downstream (southern mountain front), maximum
damage was caused by activating seemingly dormant
ephemeral tributary channels. The slope-channel coupling locally bulked the sediment supply of the trunk
river. The disaster was force amplified when the river
was temporarily obstructed by the manmade structures
(e.g., suspension bridges), and most importantly, urban
settlements (largely hotels) on the flood plain. Also,
many public buildings suffered as these were constructed in/along the ephemeral tributary channels, which
were temporarily blocked by these structures, as well
as by logged tree trunks. The Beas flood is yet another
brutal reminder to change our perception towards the
developmental approach, given that extreme events are
projected to increase in the Himalaya.

Subject: A study on swarm-intelligence in group decision-making of farmers’ self-help groups in Uttarakhand, India
Keywords: Agricultural extension, group decisionmaking, self-help groups, swarm-intellig
Abstract: The concept and utility of self-help groups (SHGs) are
proven facts, and they have significantly contributed to
group-led extension activities on a large scale. These
SHGs play an instrumental role in empowering their
members and in many core aspects of farming. Still,
these groups also face various challenges, among which
ineffective group decision-making is prominent. Therefore, it is critical to strengthen the SHGs by resolving
the issues of stability for strengthening the extension
system in light of agriculture and rural development at
the national level. Swarm intelligence is a phenomenon
through which the swarm of honeybees perform various
group tasks and takes crucial group decisions effectively
and efficiently, utilizing their collective intelligence.
Therefore, the study was intended to map the group
decision processes among honeybee swarms and their
inbuilt influences to relate them to the decision-making
processes among SHGs. The present study inferred
that seven key factors, i.e. decision impulse, conviction of
the decision, engagement in decision, decision duration,
decision alignment, extent of participation and real time physical negotiation, contributed to the effectiveness
of swarm-intelligence-based group decision-making.

Abstract: The present study reports the well-preserved Ediacaran sack-like soft-bodied fossils assigned as Finkoella
ukrainica and Finkoella oblonga from the Sonia Formation of the Jodhpur Group, Marwar Supergroup,
western Rajasthan, India. The F. ukrainica is found in
elliptical, ovate-shaped and sometimes oblong or cucumber-shaped forms with a distinct short neck, and a
small circular protrusion or depression may be present
on the organism. F. oblonga is elongated, ovate to cucumber-shaped fossil specimen with poorly preserved six
longitudinal low grooves and ridges arranged parallel
to the marginal ridges of the organism. Both F. ukrainica and F. oblonga are also well comparable to the type
materials of Ukraine in the preservation of concave
(negative relief) and convex (positive relief) with
oral/atrial siphons, double marginal ridges/grooves
and elevated edges in the Sonia Formation. The Finkoella fossil remains are believed to be the flattened bodies
of tunicate organisms. Similar sack-shaped Burykhia
fossils recorded in the White Sea of Russia contrasted
to sponges and similar hollow-shaped organisms have
been interpreted and compared with lichenized fungi
and fungal affinity. Thus, the biological affinity of the
Finkoella organism is still unresolved.

Abstract: In the present article, a methodology has been discussed
to evaluate the influence of activity concentration of
soil samples containing heavy metals in the environment.
The approach leverages a simulated germanium detector and a cylindrical geometry sample configuration to
analyse soil samples with varying densities. The results
showed a positive correlation between the soil densities
and activity concentration, with an average correlation
coefficient of 0.99 indicating that variations in density
affect the activity concentration measurements. To
mitigate this error, a demonstration of the self-absorption correction as a function of density, being an essential part of the present study has been included.

Abstract: Geospatial information on river gauging stations, such as station locations, catchment boundaries,
river flow paths and other hydrographic data are basic building blocks of hydrological analyses.
Such information for India’s river basins is available from Central Water Commission (CWC) and
water resources information system (WRIS), but is limited in extent and unreliable. Using widely
used global hydrography products, catchment boundaries were delineated for 100 gauging stations
in the Ganga river basin (GRB), and their catchment areas were estimated. The delineated boundary
for the GRB, and also station-wise catchment areas from the present study were much more consistent
with global hydrography products than those available from CWC and WRIS. Lack of reliable, analysis ready hydrography data is a hindrance to hydro-climatological research. The long-term objective of
this study is to help build such a needed dataset using high-resolution remote sensing products.

Abstract: Estimates by the Central Water Commission (CWC) on flood damage to crops,
houses and public utilities from 1953 to
2020 is about Rs 4 lakh crores (INR 4 trillion)1
. Therefore, a comprehensive flood
forecasting and early warning framework
for India is essential to mitigate the above
damage. The main input for flood forecasting is the availability of dependable rainfall forecasts. Despite the stochastic nature
of rainfall forecasts, the methodologies
adopted in India for flood forecasting are
mostly deterministic in nature. Hence, there
is a need to translate the ensemble rainfall
forecast into an ensemble hydrologic prediction by integrating meteorologic forecast, hydrologic and hydraulic models
.
With the advancement of science, reliable
rainfall forecasts are made possible with
sufficient lead time from many weather
forecasting models.

Subject: Assessment of agricultural land area lost due to Brahmaputra riverbank line erosion in Assam
Keywords: None
Abstract: The River Brahmaputra is characterized by
its exceedingly large flow, enormous volume of sediment load, continuous changes
in channel morphology, rapid bed aggradations, bank line recession and erosion.
Heavy rainfall, associated with severe
flooding, excessive siltation and migration
of river channels, causes erosion on both
sides of the Brahmaputra river. The river
has a braided channel in most of its course
in the alluvial plains of Assam, and the
river flows through 21 districts of the state.
The braided nature, lateral changes in
channels and continuous migration of rivers
cause severe erosion along the banks, leading to a considerable loss of good fertile
land each year. Shear failure due to undercutting upper bank materials during high
flooding and over-steepening of bank materials also leads to bank failures in both
the banks1–3
. Damages caused by erosion
run into several hundred crores every year.
Bank erosion by the rivers has been a serious issue for the last six decades as more
than 4.27 lakh hectares (ha) of land have
already been eroded by the River Brahmaputra and its tributaries since 1950, which
is 7.40% of the area of the state. As assessed, the annual average loss of land is
nearly 8000 ha. The width of the River
Brahmaputra has increased to 15.00 km in
some places due to bank erosion (https://
waterresources.assam.gov.in/portlets/flooderosion-problems).

Subject: Propelling Indian economy through space exploration and applications
Keywords: None
Abstract: The performance of the global economy is
supposed to be ruled by the economies of
each country1
. With this, the economic instability that countries experience during
global crises creeps in, as evident from the
Global Economic Outlook Report 2020,
which emphasized how the COVID-19
pandemic affected the global economy2
.
However, when it comes to the space
economy, countries seem to show resilient
support for multiple reasons, as evidenced
by research from Morgan Stanley, which
expects the global space industry to grow
into a US$ 1.1 trillion market by 2040,
from about US$ 350 billion in 2016 (ref. 3).
One of the reasons is that the various space
stakeholders use a sustainable approach to
space research. For example, in scenarios
where stakeholders from one country specialize in cost-effective satellite launches,
support other countries to launch their satellites into orbit, thereby reducing resource
wastage and effective utilization of financial resources. Other reasons include investor sentiments, which lead to volatility in the
stock market (changes in support and resistance), thus affecting the returns4
. Such
an effect was not seen in the space industry,
as the effect of support and resistance on
the overall share market did not affect the
space companies due to most of them not
being listed in popular stock exchanges, for
example, SpaceX and Skyroot Aerospace
Private Limited5
. This resulted in an ultimate decline in costs for space-based ventures, resulting in the realization of the very
celebrated aspiration of ‘SPACE FOR ALL’,
as obvious from making spacesuits for
women3
, which earlier were not a priority

Subject: Hundred years of research on Drosophila ananassae has revealed a number of unusual features of this species
Keywords: None
Abstract: Drosophila ananassae was originally described by Doleschall in 1858 from Ambon Island in Indonesia. This
species came into notice when Morgan, Bridges and Sturtevant compiled data in a volume entitled ‘The Genetics of Drosophila’ in 1925 as D. caribbea Sturtevant in the chapter ‘other species of Drosophila’. Kikkawa in
1935 verified D. caribbea as D. ananassae. The first mutation in this species was curved wing, an autosomal recessive gene on II chromosome reported by Sturtevant in 1921. Since then D. ananassae has been utilized extensively for different kinds of studies and results of these studies conducted during the last hundred years have
clearly revealed that D. ananassae is genetically unique species and stands distinct from other species of the
genus Drosophila. The important unusual features of this species are: spontaneous meiotic male recombination,
presence of chiasmata in males, high mutability, optic morphology hyper mutability system, absence of genetic
coadaptation, Y-4 linkage of nucleolus organizer, high frequency of pericentric inversions and translocations,
population substructing, parthenogenesis, extra chromosomal inheritance, incipient sexual isolation, inversion
karyotypes and mate recognition system, spontaneous genetic mosaic, segregation distortion, lack of correlation
between crossing-over and chromosome distance between inversions, rare male mating advantage, trait and sex
specific fluctuating asymmetry, female and male remating and sperm displacement, speciation in south Pacific
populations, association with a bacterium Wolbachia, variation in resistance to environmental stress, nutrition
regulated stress resistance, correlation between inversion karyotypes and mating propensity and phylogenetic
relationship with its sibling D. pallidosa which is in statu nascendi

Keywords: None
Abstract: The United Nations Climate Change Conference COP 28
was held and concluded in Dubai. It is particularly important
as the first ‘global stocktake’, a process for countries and
stakeholders to examine the progress towards meeting the
goals of the Paris Agreement. The conference outcome
was a revelation of the slow progress in most areas of climate
action. Consequently, nations collectively made a pronouncement on the way forward to accelerate climate action. As
usual, transitioning from fossil fuels to renewable energy
sources was one of the focus areas.
