Subject: Thermal regimes, age and sex modulate feeding attributes of Zygogramma bicolorata Pallister (Coleoptera: Chrysomelidae)
Keywords: Age, biocontrol, food, sex, temperature, Zygogramma bicolorata.
Abstract: Feeding attributes of phytophagous insects are greatly
influenced by abiotic and biotic factors. Therefore, we
assessed the combined effect of temperature, age and
sex on food consumption and utilization efficiencies of
Zygogramma bicolorata Pallister. This Mexican beetle
is known as one of the most promising candidates for
the biocontrol of Parthenium hysterophorus Linnaeus,
a noxious weed of barren, grazing and farming lands.
Temperature, age and sex influenced food consumption,
its utilization and ecological efficiencies of the beetle.
Temperature between 27°C and 30°C was found optimal for 20-day-old adults of Z. bicolorata to convert and
utilize the food biomass to body mass. Above and below
the optimal temperature and age, the feeding attributes
declined. Young females kept at 27°C consumed more
food and laid more number of eggs compared to other
females at different temperatures. This study reveals
that females are more voracious feeders than the males
regardless of temperature regimes. The present findings
can be helpful to mass-multiply Z. bicolorata in the laboratory for the biocontrol of Parthenium weed in fields
and agricultural farms. The results also suggest that
global climate change may affect the biocontrol potential of the insect, but field investigations are needed to
support the present findings.

Subject: Incubation study of kinetics and mineralization rate of nitrogen in organic sources of Ultisol
Keywords: Incubation study, kinetics, nitrogen mineralization, organic sources, traditional farming practice.
Abstract: Age-old traditional farming practices are generally followed by tribal inhabitants using locally available organic
sources of plant nutrients. The aim of the present study
was to determine the kinetics and rate of mineralization
of different local organic sources of North East region
of India. An incubation study of 100 days was carried
out using locally available organic sources, i.e. farmyard
manure (FYM; T1), poultry manure (T2), pig manure
(T3) and vermicompost (T4) at the rate of 120 kg N/ha
(considering recommended dose of fertilizer of rice as
120 kg N/ha). Bulk soil sample of Typic kandihumultis
at 0–15 cm was collected from the College of Post
Graduate Studies in Agricultural Sciences, Umiam,
Meghalaya research farm and treated with organic
sources and kept in an incubator at field capacity soil
moisture and 25°C temperature. Observations were
taken at 10 days interval up to 100 days of incubation
(DOI). A control treatment (T0) of no organic source
was used for comparison. The results showed that the
average nitrogen mineralization rate (Nmin) of T3 was
highest (64.88%), followed by T2 (57.77%), T4 (42.98%)
and T1 (35.24%). The highest Nmin rate of T3 and T2
was noted at 60 DOI as 79.37% and 76.10% respectively.
At 50–60 DOI, total nitrogen, available nitrogen and
nitrogen fractions (ammonical nitrogen and nitrate nitrogen) released were the highest irrespective of the organic
sources. R2 (coefficient of determinate) of first-order
kinetics of all organic sources was found to be: 0.91
(T3) > 0.90 (T2) > 0.89 (T4) > 0.88 (T1), while R2 of second-order kinetics was: 0.66 (T3) > 0.65 (T2) > 0.64 (T1
and T4). It has been concluded that T3 is the best organic
nutrient source among the treatments considered for
this study.

Subject: Data envelopment anaylsis in estimating economic efficiency of farm credit for adopting good agricultural practices in mango cultivation in Tamil Nadu, India
Keywords: Data envelopment analysis, economic efficiency, farm credit, good agricultural practices, mango cultivation
Abstract: Good agricultural practices (GAPs) in mango production
are essential to enable farm produce to be internationally
competitive with sufficient institutional credit. Economic
efficiency of 0.45 and 0.68 respectively for conventional
and GAP farms in Krishnagiri district of Tamil Nadu,
India implies that there is scope to increase mango
output by 55% and 32% respectively, by optimum allocation of resources. The highest return invested by GAP
borrowers might be due to efficient use of resource and
GAPs. The extension workers should develop strategies
to increase income through adoption of GAPs, efficient
use of resources and strengthening the loan delivery
mechanism to enhance mango production.

Subject: Effective elastic thickness of the continental lithosphere with particular reference to the India–Eurasia collision system
Keywords: Continental rheology, effective elastic thickness, flexural modelling, isostasy, lithosphere
Abstract: The effective elastic thickness (EET) of the lithosphere
is a measure of the lithosphere’s ability to flex under
long-term geological and topographic loads. It is often
estimated through analyses of gravity and topographic
data. The EET has a significant role in regulating the
geodynamic evolution of both the continental and oceanic
plates. Estimates of EET derived from geophysical data
are consistent with rheological models in the oceanic
regions. However, there are extensive debates on the
estimates of EET and rheological models over the continental areas; differences are probably due to the complex
structure and history of the continental plates. For instance, according to one model of continental rheology,
popularly known as the ‘Jelly Sandwich’, the mechanical
strength of the lithospheric plate is distributed in the upper crust and the lithospheric mantle. In another model,
dubbed as ‘Crème Brulee’, the lithospheric mantle is
weak, and the mechanical strength of the lithosphere is
limited to the upper portion of the crust. These model
differences have arisen because of inconsistent results
obtained using different datasets, e.g. the distribution of
earthquakes, EET, gravity anomaly and rheology. This
article discusses the evolution of these contrasting models
and the critical necessity to resolve the model differences.

Subject: Protected vegetable cultivation for climate resilience and nutritional security in Eastern Ladakh, India
Keywords: Climate resilience, extreme climatic conditions, nutritional security, organic products, protected vegetable cultivation
Abstract: Eastern Ladakh, India, experiences a harsh climate with temperatures dropping below zero, thus restricting agricultural activities for a short period. Therefore, the inhabitants depend completely on dairy
products, packed and processed foods. Traditional farming practiced in the study region is purely
indigenous and, by default, organic in nature. Therefore, the region has the potential to produce organic products under protected structures, which will be a source of income generation. The present
study was conducted through frontline demonstrations at three locations, viz. Nyoma, Mudh and Tsaga
in Ladakh for two consecutive years from 2019 under protected structures, viz. local greenhouse and
low tunnel. A comparison of productivity levels between demonstrated variety and local checks was
also made. A significant outcome was that the farmers have learned to produce quality vegetables not
just to increase their income but also for nutritional security. There is a positive attitude among the
locals on the importance of protected cultivation as a self-sustainable technology, nutritionally secure,
and uplifting socio-economic conditions with climate-resilient features that will be a boon for this
region despite extreme climatic conditions

Keywords: Biofortification, consumer awareness, malnutrition, perception, willingness to pay
Abstract: Malnutrition, which can perpetuate a cycle of poverty and ill health, will disproportionately impact
people. Biofortification is an initiative to ensure improved nutritional outcomes in developing countries, where approaches to food supplements and commercially marketed fortified foods are limited.
A primary survey was carried out in and around the National Capital Territory (NCT) of Delhi, India.
A total of 134 respondents from urban and 123 respondents from rural areas were interviewed. The
results revealed that the majority of respondents in urban areas (72%) presumed that biofortified
products were higher in micronutrients than those in rural areas (49%). The findings reveal that age
and gender negatively impact consumer awareness of biofortification, while education, food habits
and income exert a positive and significant impact. The policy implications drawn should enable the
development of consumer-based food products by creating a niche market and using an appropriate
marketing channel to increase consumer acceptance and WTP.

Keywords: Localized eradication, mango stone weevil, Sternochetus mangiferae,Fabricius, Coleoptera, Curculionidae, India
Abstract: The mango stone (nut) weevil (Sternochetus mangiferae) is a monophagous pest of
mango, Mangifera indica. It is found in
almost all the mango-growing areas of the
world, except Egypt, Italy, Israel and the
Canary Islands
. In India, it is found mainly
in the south2
. The adults lay eggs on immature fruits of 2–4 cm diameter. The grubs
that hatch bore into the core of the fruit
and eventually get enveloped by the seed
coat. The grubs pass through five instars
and pupate within the seed. The adults that
emerge from the seed burrow through the
pulp and emerge through a hole in the
rind3,4. During this process, they damage
the pulp and contaminate it with their excreta, making it unfit for market, export
and industry
. The overall loss varies from 5% to 80% (ref. 5). Early infestation can also
lead to fruit drop. The weevil is of quarantine significance in fresh fruit export.

Subject: Designation of Ranipur Wildlife Sanctuary as Tiger Reserve: steps towards landscape level biodiversity conservation
Keywords: Designation of Ranipur Wildlife Sanctuary, Tiger Reserve, landscape level biodiversity conservation
Abstract: It is now widely acknowledged that landscape-level conservation is an important
paradigm that addresses scaling up our
conservation initiatives and actions, especially when the entire world, including wild
species, faces the consequences of climate
change, pollution and expanding linear infrastructure. Current conservation instruments, including the protected areas on
which the species rely, are insufficient to
halt biodiversity loss. Thus, conservation
initiatives in the wider landscape surrounding protected areas are needed to achieve
the impact required for reversing negative
biodiversity trends1
. Landscape conservation facilitates bringing all the sectors and
stakeholders in a single platform to collaborate their ideas on managing important
biodiversity areas for long-term sustainability. As several ecological and evolutionary processes are associated with the
management of an area, systematic conservation planning is needed to ensure sustainable developments of the area, including
economic, cultural, social and economic
developments. Over the last decade, Governments have been making efforts to consider
the biodiversity-rich areas and management and conservation of species across
the larger landscapes, not confining the
conservation approaches to the protected
habitats

Abstract: Climate change is a global emergency. All
countries must remove 7.6% of atmospheric
carbon dioxide (CO2) per year from 2020
to 2030 so the temperature does not exceed
2°C. If this is not implemented, the impacts
will be catastrophic, resulting in major disaster risks, according to the Paris Agreement
2015. In this critical situation, mangroves
can provide a nature-based solution for climate change issues as they are a carbon-rich
system that efficiently removes atmospheric CO2, generating higher carbon biomass
than any other aquatic systems and also
stores far greater carbon than any other
ecosystem on the Earth1,2, making them
indispensable for climate change mitigation

Keywords: pragmatic approach, formatting manuscripts, research papers
Abstract: Are you annoyed by the insistence of some
journals on exact formatting, such as ‘Do
not put a period at the end of figure captions’ or ‘Use superscript numerals to indicate affiliations’? ‘Wish the journal would
give greater attention to having my manuscript reviewed quickly than to such formatting trivia’, I hear you muttering. Research
itself is difficult and costs money, time and
effort, and writing an account of that research in the form of a publishable manuscript is not particularly easy either. By the
time a manuscript is ready for submission
to the chosen journal, its authors have exhausted nearly all the energy and attention
they are willing to spend on that research –
and need to keep plenty in reserve for addressing the reviewers’ comments, multiple
revisions and proofreading. After uploading their manuscripts, authors would probably turn with relief to the next research
project instead of wasting their time on
checking whether ‘&’ is used instead of
‘and’ in parenthetical citations or whether
the citation number is placed after – instead
of before – the dot that ends a sentence.

Keywords: Adaptive time series compensator, earthquake response, numerical damping, real-time hybrid simulation, viscoelastic damper.
Abstract: Real-time hybrid simulation (RTHS) is a state-of-the-art,
accurate, affordable method for simulating seismic effects
on structures with loading rate-dependent behaviour.
In RTHS, a part of the system that cannot be accurately
modelled numerically is simulated experimentally in the
laboratory, and the rest numerically. The response of
the hybrid system is obtained in real-time by solving the
governing equations of motion. This communication
demonstrates an implementation of RTHS in the Pseudo

Subject: Copper–gold mineralization and associated hydrothermal alteration around Suwara area, southern part of the Bundelkhand craton, Central India
Keywords: Craton, granitoids, hydrothermal alteration, mineralization, quartz reefs.
Abstract: The structurally controlled copper–gold (Cu–Au) mineralization in the Suwara area in the southern part of the
Bundelkhand craton, Central India, is hosted within
quartz reefs traversing older granitoids. Mineralization is
distinctly associated with hydrothermal alteration (potassic, chloritic and iron alteration in the ore zone and Kmetasomatism in the wall rocks). Field observations
and laboratory evidence confirm the Fe–Cu–Au association in the study area. Sulphide mineralization is represented by pyrite, chalcopyrite, covellite, chalcocite
and bornite occurring as disseminations, stringers and
specks within the altered quartz veins, with gold occurring as fine isolated disseminations within quartz and
iron oxides. Chemical analysis of surface and subsurface
samples showed promising values for Cu (up to 1.0%)
and Au (up to 450 ppb) content. Fluid inclusion studies
indicated the occurrence of saline mineral fluids (Na–
K–Cl-bearing) with the presence of H2O–CO2–CH4 in
the mineral system. Overall characteristics of the mineralization and alteration patterns of the prospect indicate
that it probably belongs to an iron oxide–copper–goldtype set-up for mineralization. The present study on
Cu–Au mineralization from the southern Bundelkhand
craton will have significant implications for further exploration and research in the area

Subject: Identifying suitable digital elevation models and deriving features for landslide assessment in Idukki District, Kerala, India
Keywords: Digital elevation models, geomorphological and hydrogeological features, landslide, spot height, vertical accuracy
Abstract: This study compares the vertical accuracy of different
digital elevation models (DEMs), such as Cartosat-I,
ASTER-GDEM, SRTM-GL1, ALOS3D30 and FABDEM
with a resolution of 30 m, to the toposheet-derived 264
spot heights of Idukki district, Kerala, India, obtained
from the Survey of India. We quantitatively assess the
vertical accuracy of these DEMs by analysing their accuracy against randomly selected topographic map spot
heights. The study also validates the accuracy of the
DEMs by evaluating the vertical accuracy separately
for different elevation classes representing varying terrain characteristics of the Idukki district. Statistical
measures are used to evaluate the performance of the
DEMs. The results of the study show that FABDEM
exhibits an RMSE of 41.79 m, which is lower than that
of other models. The study utilizes FABDEM to derive
a set of 12 geomorphological and hydrogeological features, including slope, aspect, elevation, profile curvature,
plan curvature, distance to road, relative relief, ruggedness index, drainage density, height above near drainage,
wetness index and stream power index. The characteristics of various parameters are analysed. The uniqueness
of this study lies in its utilization of geomorphological
and hydrogeological features derived from FABDEM
that directly impact the susceptibility of landslides in
the region. The study identifies that a combination of these
dynamic and static parameters, which vary with elevation classes, plays a significant role in determining
landslide occurrence in this region.
