The Marsh Babbler (Pellorneum palustre) is an endemic species of grassland bird found in the river floodplains of North-East India and Bangladesh. Much remains unknown about the Marsh Babbler due to its elusive behaviour and the difficult habitat that it occupies (which also remains inaccessible during monsoons). Destruction and conversion of the unique tall grassland habitats have, however, decimated its already low population, escalating the species to ‘globally threatened’. A new paper by Anand Krishnan and colleagues quantifies the composition, signal space and phylogenetic diversity of these bird acoustic communities. Enhanced understanding of the species' natural history and its association with its habitat will go a long way in ensuring its long-term conservation. Image credit: Siva R.

RESEARCH ARTICLES
Modulation of mitochondrial nucleoid structure during aging and by mtDNA content in Drosophila
Summary: The TFAM-nucleoid structure is critically regulated by mtDNA content and changes during aging. Mitochondrial transcription factor B2 plays a role in mtDNA replication.
miR-8b is involved in brain and eye regeneration of Dugesia japonica in head regeneration
Summary: Most miRNAs in planarians are homologous to humans and other mammals, and may also play a similar regulatory role. Knockdown miR-8b planarian miR-8b induces brain and eyespot defects during head regeneration.
Altered germline cyst formation and oogenesis in Tex14 mutant mice
Summary: Altered germline cyst formation and fragmentation due to defective germ cell connectivity leads to changes in oocyte differentiation and development in Tex14 mutant mice.
Tight junction stabilization prevents HepaRG cell death in drug-induced intrahepatic cholestasis
Summary: Exposure to forskolin or sodium taurocholate facilitates tight junction (TJ) formation in HepaRG cells cultured with entacapone and suppresses bile canaliculi dynamic changes, leading to the inhibition of TJ disruption and cell apoptosis.
Convergent acoustic community structure in South Asian dry and wet grassland birds
Summary: Acoustic communities of different grassland biomes exhibit convergent signal space in spite of dissimilar species compositions.
Heart rate and startle responses in diving, captive harbour porpoises (Phocoena phocoena) exposed to transient noise and sonar
Summary: Trained porpoises respond initially to sonar sound exposure with intensified bradycardia, but habituate rapidly, whereas 40 kHz pulses consistently evoke a startle, but elicit no other behavioural or heart rate changes.
Associative learning in larval and adult Drosophila is impaired by the dopamine-synthesis inhibitor 3-Iodo-L-tyrosine
Summary: We surveyed the effects of a dopamine-synthesis inhibitor on associative learning in larval and adult Drosophila. This approach can supplement genetic tools in investigating the conserved reinforcing function of dopamine.
The kidney of the Nodularia freshwater mussel has a larger filtration-size and counter-current system with improved water excretion compared with the seawater mussel Mytilus
Summary: The molecular weight cut-off of the freshwater mussel Nodularia douglasiae (22 kDa) is larger than the seawater mussel Mytilus (0.5 kDa), and N. douglasiae has better water excretion with a counter-current system.
Exocrine pancreas proteases regulate β-cell proliferation in zebrafish ciliopathy models and in murine systems
Summary: In this paper, we examine the role of exocrine pancreas protease genes in β-cell number using zebrafish and murine models, and identify a novel relationship between the two.
Postnatal expression profiles of atypical cadherin FAT1 suggest its role in autism
Summary: This study describes a novel role of FAT1 in postnatal brain development and its potential contribution to the etiology of autism spectrum disorder.
MICAL-L1 is required for cargo protein delivery to the cell surface
Summary: MICAL-L1, an effector of Rab GTPases, exhibits a significant colocalization with markers of the Golgi apparatus and recycling endosomes. It is involved in cargo delivery to the plasma membrane.
Developmental and adult acclimation impact cold and drought survival of invasive tropical Drosophila kikkawai
Summary: In body color morphs of tropical Drosophila kikkawai, plasticity induced a higher level of resistance to cold and drought as well as three energy metabolites, which are likely to support its invasive potential.
RNA-Seq reveals changes in human placental metabolism, transport and endocrinology across the first–second trimester transition
Summary: Full onset of the maternal circulation to the human placenta at 10–12 weeks of gestation is associated with transcript changes indicative of switches in protein processing, hormone secretion, transport and vasculogenesis.
METHODS & TECHNIQUES
Quantitative evaluation of individual food intake by insectivorous vespertilionid bats (Chiroptera, Vespertilionidae)
Summary: This study applies a combination of experiment in captivity and field survey that can be used as an easy methodological approach to estimate insect biomass consumed by bats.

The power of planaria
In their Research Article, Orel Benita and colleagues obtain the first recording of well-defined extracellular multiunit activity from the freshwater planarian brain by a straight-forward technique. These traits combined with their exceptional regeneration capabilities, allow for neurobiological experiments not possible in any other model organism such as an electrophysiological recording from planaria with two heads that control a shared body.
