Abstract: Foret is a unique natural local resource of global importance. India is one of the mega biodiversity countries of the world, and is home of 7.7% of world's bio-diversity .Non-wood forest products (NWFPs), also called Minor Forest Produce, although they are by no mean minor-are known to be source of livelihoods for over 300 million people living in and around forests and are in fact associated with their socio-economic and cultural lives.However, due to timber centric forest managemt , NWFPS have not got the importance they deserve.In recent years, the Non Wood Forest Resources 9NWFRs) have gained importance due to their being vital source of livelihood for forest dependent communities and having a multiplier effect in the economy through employment generation in downstream value addition and trading activities. Multiplicity of Acts having a bearing on NWFRs has further compounded the prevalent confusion with regard to their ownership and management responsibilities.

Keywords: Asian Elephant, Himachal Pradesh, Human-elephant conflict, Shiwalik range, Range expansion
Abstract: The state of Himachal Pradesh is situated in Northern Himalayan landscape of India. Sporadic annual movement of elephants has been reported historically from Rajaji National Park, Uttarakhand to Col. Sherjung National Park, contiguous to Paonta Sahib in Himachal and adjoining Kaleskar National Park, Haryana. Presence of resident population in this area however is a recent phenomenon since the last few years. Presently, a resident population of 14-16 Asian elephants (Elephas maximus) has established in Sai forests of Paonta Sahib Fiorest Division, in a non-traditional range, highlighting adaptability to fragmented landscapes.This has enhanced cases of human-elephant conflict (HEC) with increased crop raid, damage and human fatality. Efforts have been made by Forest Department with financial assistance under Project Elephant in taking the conversation from conflict to co-existence. The article offers a case study for managing small, isolated herds to balance conservation and coexistence in a human-dominated landscape.

Subject: Understanding recent variations in the zero year-class entries of Indian oil sardine and its impact on the fisheries of Kerala
Keywords: Eco-regions, primary productivity, sardine, small pelagic, spawning stock biomass
Abstract: The Indian oil sardine (IOS) fishery along the Kerala
coast from 2021 to 2024 was assessed using an ecoregion approach, revealing a significant increase in recruitment in 2024 compared to previous years, and at
varying scales. The ecosystem productivity indicators
showed a stronger influence on recruitment dynamics
than the biological indicator of spawning stock biomass.
The relative contributions of micro-, pico-, and nanoplankton functional groups indicated linkages with the
physio-biological dynamics of IOS and need further
research. The present study highlights region-specific
environment variability, especially during the prespawning and pre-recruitment periods, that needs to
be adequately integrated into stock assessments and
dynamic management frameworks. Development of
species-specific, eco-physiological indicators for timely
fisheries governance interventions to sustain the fishery of IOS under changing oceanographic conditions
and supporting the development of short-term forecast
models is recommended

Subject: Comparative assessment of mustard (Brassica juncea) genotypes under Populus dectoloides and Eucalyptus teretectornis based agroforestry systems for soil carbon maintenance: an implication for climate change alleviation
Keywords: Biomass production, climate resilience , CO2 mitigation, soil carbon
Abstract: The current situation of climate variability can be
buffered by the inclusion of agroforestry as a critical
land management system. The enormous potential of
trees to capture and store carbon from the atmosphere
and their role in soil nutrient cycling are globally acknowledged. Alongside this, we need to develop crop
varieties that could perform well in competition with
trees to share resources like sunlight, water, and soil
nutrients. Therefore, the present study was undertaken in the tarai belt of the Himalayan foothills to
screen suitable mustard varieties and under Poplar and
Eucalyptus-based agroforestry systems. Besides this,
biomass and carbon sequestration potential were also
quantified for different components. In. Ten different
Indian mustard varieties were screened under Populus deltoides and Eucalyptus tereticornis. Variety CS56
produced higher biomass in all three land management
systems, i.e., poplar, eucalyptus agroforestry system,
and open field E. tereticornis was found to have larger
climate resilience potential with higher biomass production (91.99 ± 18.21 to 270.19 ± 16.55 Mg ha-1) and
CO2 mitigation (151.92 ± 30.08 to 446.21 ± 27.33 Mg
CO2 ha-1). However, biomass production of the mustard crop was better in a poplar-based agroforestry
system.. The total Biomass accumulation, carbon content, and carbon dioxide mitigation showed the following trend: eucalyptus + mustard > poplar + mustard>
mustard (open field). Biomass deposition in mustard
crops varies from sole crop (open field) > Poplar +
mustard > Eucalyptus + mustard. The changes in soil
carbon stock after two rabi season was recorded to
be higher in eucalyptus-based agroforestry (1.29 Mg
ha-1) system and lowest in open field (0.43 Mg ha-1).
SOC showed improvement under an agroforestry system compared to an open field or pure crop system.

Subject: Economic assessment of natural farming over conventional methods in Himachal Pradesh, India
Keywords: Conventional farming, cost of cultivation, economic analysis, Himachal Pradesh, natural
Abstract: India’s agricultural sector has achieved record-breaking
food grain production while grappling with significant
challenges such as soil degradation and an over-reliance
on chemical inputs that threaten its long-term sustainability. The present study examines the effectiveness
of natural farming over conventional farming practices in the Kangra district of Himachal Pradesh. Key
metrics such as cultivation costs, crop yields, and net
returns were focused on using the data collected from
a primary survey. The findings indicate that natural farming achieves a cropping intensity of 190.62%,
while conventional farming reaches 136.12%, suggesting more efficient land utilisation. Additionally, natural
farming typically incurs lower cultivation costs, primarily due to the use of locally sourced inputs. For the
kharif season, the vegetable–pulse combination in natural farming produced the highest net farm income of
| 27,092, compared to | 18,978 from conventional paddy
farming. However, challenges like limited market access and labour intensity remain persistent. This study
highlights the need for supportive policies to enhance
the adoption of natural farming practices, promoting
both profitability and environmental sustainability.

Abstract: Customised real-time model guidance from the
seamless prediction system of the National Centre
for Medium Range Weather Forecasting (NCMRWF)
supported the 12th Indian Scientific Expedition to
the Southern Ocean (ISESO12). Atmospheric model
guidance was prepared from the NCMRWF Global
(NCUM-G) model forecast. The NCMRWF Coupled
(C-NCUM) global model was used to prepare ocean
and sea ice products. Daily model guidance of atmospheric and ocean variables from model analysis and
forecast for the next five days with 24-hour interval, was
delivered to ISESO12 science team. The wind speed,
maximum air temperature, minimum air temperature and rainfall from the automatic weather station
of the research vessel were compared with model guidance. Model forecasted air temperature was found to
be in good agreement even with five day lead forecast. Wind speed was slightly underestimated with
a better reliability of model guidance. Whereas, the
rainfall estimates were found to be challenging and
less accurate from the model guidance. However, the
situational awareness support was found to be critical
in informed decision-making for the safe and efficient
accomplishment of the scientific objectives of ISESO12.

Subject: Evaluating the nutritional composition of edible insects: an alternative source of food supplements in Nagaland
Keywords: Amino acid, entomophagy, foods, nutrients, protein
Abstract: Edible insects are rich sources of macronutrients such
as protein, lipid and carbohydrate, and they are considered a promising alternative source of nutrients to alleviate food security. However, the nutritional profiling
of edible insects is very limited, highlighting the need
to evaluate their potential as a promising source of nutrients. Therefore, the present study was conducted to
assess the nutrient composition of nine commonly consumed edible insects in their fresh, fried and roasted
forms, as well as to examine the variations across development stages (larva, pupa and adult) of Provespa
barthelemyi. The results showed that protein concentrations varied significantly (F(2) = 293.8, p < 0.05) among
fresh, fried and roasted forms. Lipid content ranged
from 0.01 ± 0.00 (Laccotrephes ruber) to 0.5 ± 0.06
(Samia cynthia ricini) in fresh, 1.09 ± 0.08 (Tarbinskiellus portentosus) to 1.27 ± 0.08 (Cossus spp.) in fried,
and 0.4 ± 0.0 (Mecapoda nipponensis) to 1.3 ± 0.0 (Oecophylla smaragdina) in roasted form. While carbohydrate content ranged from 0.2 ± 0.0 (L. ruber) to
5.8 ± 0.5 (O. smaragdina) in fresh, 0.6 ± 0.0 (Lethocerus
indicus) to 12.17 ± 3.78 (Cossus spp.) in fried, and
0.5 ± 0.3 (L. indicus) to 13.1 ± 3.8 (Cossus spp.) in
roasted form. Across the developmental stages of P.
barthelemyi, the highest amount of protein, lipid and
carbohydrate was present in the larval stage. Further,
eight essential and nine non-essential amino acids were
also present in edible insects. Insects such as O. smaragdina and P. barthelemyi have moderate to high levels
of both essential and non-essential amino acids, such
as leucine, phenylalanine, alanine, glycine and proline,
suggesting they can serve as a well-rounded protein
source for humans. The present study highlighted that
edible insects are compelling food supplements that can
serve as a promising alternative source of nutrients.

Subject: Why use vertical stratification and directionality to assess insect foraging behaviour on trees?
Keywords: Citrus, directionality, foraging rates, honeybees, pollination, vertical stratification
Abstract: The studies on foraging behaviour of pollinators on
different crops have been made by observing the number of insects visiting marked plots per unit time. This
holds true for crop plants where the plants have the
same height and the crop is uniformly distributed,
where observations can be made on marked plots
randomly selected in the crop. The observations
can also be made by using the line transect method,
where the observer walks along the strip of the crop
and records insects. However, in tree plants, flowers are located at different heights and in different
directions, and more or less have different microclimatic conditions facing east, west, north, and south.
Therefore, investigations are needed to explore the
pollinator behaviour in relation to the height of the
plant as well as the directionality of inflorescences.
In tree-type plants, it is recommended to record observations across different canopy strata to obtain
accurate estimates of pollinator diversity and abundance. Recording observations by observing one set
of branches is unlikely to yield good results. The concentration of floral resource composition in different
canopies supports the different faunal communities.

Abstract: Fog is a socio-natural hazard common during winter
in the Indo-Gangetic Plains, disrupting transportation, health, and agriculture. The Indian Institute of Technology Kanpur fog project addresses
the challenge of fog forecasting by using data science with in situ and satellite observations. A
novel fog index quantifies fog duration and intensity, supporting medium-term forecasting, while
machine learning models achieve 0.9 accuracy for
six-hour visibility forecasts. An uncertainty-aware
Bayesian neural network using INSAT-3D data improves fog detection performance compared to the
operational INSAT fog product, increasing the probability of detection from 0.13 to 0.68. The real-time
results are publicly shared at https://fog.iitk.ac.in/.

Subject: Demonstration of spontaneous recombination in males of Drosophila ananassae as meiotic in origin
Keywords: None
Abstract: The amount of genetic variation is important in a population undergoing microevolutionary change caused by mutation
and recombination, which provides raw materials for evolution. Drosophila is extensively used in such kinds of studies and
is considered an interesting biological model since 1909, when Thomas Hunt Morgan used Drosophila melanogaster in
genetic studies for the first time. Morgan proposed the theory of linkage which states that the genes are linearly arranged
in a chromosome and may be separated by recombination between homologous chromosomes during meiosis. Further,
the strength of linkage depends on the distance between genes. In Drosophila, recombination does not occur in males, but
occurs in females. It has been shown that spontaneous crossing over in males occurs in appreciable frequency, which was
initially reported by Japanese researchers, but its mechanism of origin was not known. Later on, with the experimental
evidence, it was shown that spontaneous male crossing-over was meiotic in origin, and this evidence came from genetic
data, the presence of chiasmata and the role of inversions.

Subject: Rocky road for direct-seeded rice: understanding the adoption barriers of this climate resilient technology
Keywords: None
Abstract: Direct-seeded rice (DSR) offers several advantages over puddled transplanted rice (PTR), yet inconsistent adoption
persists due to systemic gaps in farmer knowledge, skills and institutional support. Key challenges include imprecise
land levelling, high seed rates, inefficient herbicide application and improper irrigation practices. Manual broadcasting
and delayed weed control result in uneven crop geometry, increased production costs, yield penalty and reduced farmer
confidence. Irrigation methods like sprinklers or alternate wetting and drying are recommended for DSR, yet farmers
often replicate PTR’s continuous flooding, negating water-saving benefits. DSR feasibility is region-specific, contingent
on soil texture, water availability and agroclimatic suitability. Scaling DSR requires targeting ecologically suitable regions and integrating technical, educational and policy interventions. Farmer-centric strategies (on-farm training, field
demonstrations and peer learning) can address knowledge gaps. Policy measures, such as subsidies for seed drills, laser
levellers, and weeders, alongside custom hiring centres, can enhance access to critical equipment. Financial incentives
linked to water savings or emission reductions (carbon/water credits) may further motivate adoption.

Subject: Improving weather forecasts: the way forward
Keywords: None
Abstract: Weather forecasts, once a subject of public jokes, have undergone a remarkable transformation, demonstrating their
critical importance and value. Two examples highlight this
progress. In 1998, a severe cyclone in Odisha caused 10,000
deaths. By 2019, a cyclone of similar intensity, Cyclone
Fani, resulted in only 70 fatalities, a testament to significant advancements in forecasting and disaster preparedness.
In 2024, the total number of cyclone-related fatalities was
149. The second example is the profound economic impact
of monsoon forecasts. A study by the National Council of
Applied Economic Research (NCAER) showed that for an
investment of approximately |1,000 crore in improving monsoon forecasts, the return was a staggering |50,000 crore.
This benefited over 1.07 crore below poverty line (BPL) agricultural households and 53 lakh fishing households.

Subject: Sustainable fertigation practices for improved nutrient management in Casuarina clones – a field study from farmlands of Tamil Nadu, India
Keywords: Biometric attributes, clones, correlation, crop factor, fertigation.
Abstract: The increasing need for sustainable agricultural practices resulted in the exploration of fertigation techniques that optimise nutrient management, enhance
soil health, and promote crop productivity. The present
study examined the influence of sustainable fertigation
practices on soil nutrient dynamics and growth performance in Casuarina clones cultivated across various
farmlands in Tamil Nadu, India. Based on agricultural factors, daily rainfall, evapotranspiration, and
fertiliser dosage, the recommended dose of fertiliser
(RDF) of 200 : 200 : 300 gm/plant/year, irrigation
was scheduled according to the tree’s computed water
need as potential evapotranspiration or pan evaporation (PE). The spacing regimes (1 × 1 m, 1.2 × 1.2 m,
1.5 × 1.5 m and 1.8 × 1.2 m) was distributed as main
plot; irrigation treatment combinations (50 %, 75%,
100% and 125% PE) was assigned as subplot I and
fertiliser combinations (75%, 100%, 125% and 150%
RDF) was assigned as subplot II. The growth parameters recorded in relation to basal diameter (cm), height
(cm) and volume index (cm3
) were analysed during
growth stages 5 months after treatment (MAT) and
10 MAT. At 5 MAT, I4F4 (125% PE, 150% RDF) attained maximal height (78 cm), whereas basal diameter (0.324 cm) and volume index (16.758 m3
) were
recorded maximum at I3(I-Irrigation)F3(F-Fertigation)
(100% PE, 125% RDF). At 10 MAT, I4F3 (125% PE,
125% RDF) obtained maximal height (89 cm) and volume index (33.3 m3
), whereas I3F2 (100% PE, 100%
RDF) catalouged maximal basal diameter (0.374 cm).
Using resources sustainably, the present study helps
standardise the crop’s water and fertiliser requirements, increasing Casuarina productivity and output.

Subject: Development and predation rate of Dortus primarius, a predatory mirid bug on Frankliniella schultzei larvae treated with a novel fungus Lecanicillium fusisporum
Keywords: Biology, compatibility, entomopathogenic fungi, IPM strategy, mirid bug, natural enemy.
Abstract: Dortus primarius is a predatory mirid bug that has been
recorded feeding on different insect pests. Lecanicillium
spp., an entomopathogenic fungus (EPF), is used as a
biocontrol agent against sucking pests. The combined
use of D. primarius and novel fungus Lecanicillium fusisporum may have a significant effect in controlling
sucking pests like Frankliniella schultzei. Before combined use, it is imperative to investigate the effect of
L. fusisporum on D. primarius pertaining to its biology,
predation potential and prey preference. This predator
was able to complete development when L. fusisporum
treated thrips were offered as food. The nymphal duration on treated thrips (21.11 ± 0.24 days) was four
days more than on untreated thrips. The longevity of
male and female predatory bugs fed on treated thrips
was less than that of untreated thrips. The hatching
percentage of bugs consuming fungal-treated thrips
(83.32 ± 2.68) showed no difference compared to those
fed on untreated thrips (86.47 ± 3.01). Fecundity was
found to be reduced in bugs that fed on fungal-treated
thrips. However, no adverse effects were observed in the
first filial (F1) generation derived from these predators.
An adult bug consumed an average of 13.88 ± 0.23 untreated thrips per day compared to 10.24 ± 0.49 treated
thrips. When offered both treated and untreated thrips,
various instars and adults of D. primarius consistently
showed a preference for the untreated thrips. The
results indicated no such detrimental effect on the
survival of the predatory bug and the F1 generation.
Moreover, in the choice test, bugs preferred untreated
thrips, indicating that in the presence of L. fusisporum
in the vicinity, bugs can avoid feeding on infected prey.
