This document discusses tracking changes in intestinal nematode communities in rufous mouse lemurs over three years in Madagascar. Long-term longitudinal studies of parasite communities in individual hosts are important but rarely conducted. The research questions examined whether there is consistent succession in nematode communities within individual hosts (infracommunities) and how those relate to the overall component communities across hosts. Analysis of 634 fecal samples from 78 mouse lemurs identified putative nematode species using barcoding. While component communities remained quite stable, there was significant turnover within individual infracommunities from year to year.

to help students understand the content better, look at it from a different viewpoint and excel further in their studies. This can be used as guide however it all depends on learners study methods and whatever works best for them. We hope this is useful to our students and goodluck!
Ingoldian Fungi in Kigga Falls, Chikmagalur District, KarnatakaIOSR Journals
Fungi are the ubiquitous organism.The exist in diverse forms in a range of habitats, arboreal,
freshwater, marine, subterranean and terrestrial. In fresh water we concentrated only Ingoldian fungi. The
selected study sites of foam samples and decaying debris were collected in the same study area and kept for
screening and incubation respectively. The conidia developing on decayingdebris were screened using
microscope. The collected foam samples were revealed Ingoldian fungi. In this contribution of occurrence and
abundance of Ingoldian fungi were enumerated. A total of 24 species were isolated twelve genera were
identified.

Seminar of U.V. Spectroscopy by SAMIR PANDASAMIR PANDA
Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

2. Why longitudinal surveys?
Host individual is a dynamic habitat
How parasite communities change?
Understanding interactions in
parasite communities
→ virulence, prevalence etc.
→ resistance, tolerance
Succession in parasite communities
→ host developmet
3. Long-term studies are quite
common, but...
Focus often on single
species / taxons
Focus on component
populations (= one parasite
species in a host community)
Infrapopulations (= one
parasite species in a single
host) rarely studied Photo: St. Kilda Soay Sheep Project / Arpat Ozgul
4. Research questions
Is there consistent
succession in
infracommunities?
How component and
infracommunities relate to
each other?
