Phase separation is increasingly recognized in facultative heterochromatinization of Polycomb target genes; however, the mechanisms underlying this process remain obscure. Using single-molecule imaging and tracking, we show that individual condensates in mouse embryonic stem cells (mESCs) contain approximately 3 CBX2 molecules and numerous Polycomb repressive complex (PRC)1 and PRC2 subunits and indicate that the composition and dynamics of condensates are developmentally regulated. We reveal that CBX2 clusters PRC2 and controls the spatial distribution of both PRC2 and H3K27me3. Using genomic approaches, we demonstrate that CBX2 binds to condensate initiation sites, which are enriched for PRC2 nucleation sites. CBX2 deletion causes …

Inexorably Entangled Environmental And Knowledge Commons, Todd Aagaard, Brett M. Frischmann

Faculty Publications

For people to effectively share an environment, they usually also must effectively share knowledge about that environment. While seemingly obvious and intuitive, this insight is often overlooked in literature about governing resources as commons. Focusing on the knowledge commons associated with an environmental commons helps to illuminate a host of complex governance dilemmas. This chapter examines the interrelationship between environmental and knowledge commons, weaving together different strands of commons research and practice. Examples discussed include shared pastures, forests, road systems, computer servers, social media platforms, living rooms, and antimicrobial effectiveness/resistance.

Chagas disease is a poverty-related neglected tropical disease caused by the protozoan Trypanosoma cruzi affecting approximately 6.3 million people, predominantly in the Americas. Approximately 30% of T. cruzi infections progress to chronic cardiomyopathy and 10% of these cases end in death from cardiac failure. The first-line drug Benznidazole (BNZ) require a prolonged treatment regimen and can be highly toxic. Here, we evaluate a therapeutic vaccine in T. cruzi-infected mice, based on the recombinant Trypomastigote Surface Antigen 1 (TSA-1.C4) protein and the emulsified adjuvant E6020, and in combination with a suboptimal dose of BNZ. We observed a reduced burden parasite in …

Efficient Multi-Kilobase Knock-Ins In Mice And Cell Lines Using Crispr/Cas9 And Raav Donors With Unbiased Whole-Genome Characterization By Lock-Seq, Monica F Sentmanat, Zi Teng Wang, Evguenia Kouranova, Samuel T Peters, Wan Ching Chan, Jed Lin, Yong Miao, J Michael White, Mia Wallace, Xiaoxia Cui

2020-Current year OA Pubs

Multi-kilobase knock-ins (KIs) are a necessary, yet challenging type of genome editing to create and characterize in cell lines and animals. The combination of rAAV donor transduction and electroporation of single-cell mouse embryos with Cas9/gRNA ribonucleoprotein complex enables highly efficient KI, but the insert size is limited by the viral packaging capacity. Here, we report the creation of up to 6.7 kb precise KI achieved in one step by using three rAAVs designed to insert one after the other. To fully characterize the edited genome with large KIs, we developed LOCK-seq (LOng-read sequencing of Captured Kilo-base targets), where relevant genomic …

Nonnative Crayfish In Türkiye: Presence Records, Invasion Pathways, And Ecological Risks, Muzaffer Mustafa Harlioğlu

Turkish Journal of Zoology

The globalization of trade, aquaculture, and the ornamental pet industry has accelerated the transboundary movement of nonnative crayfish species, with significant ecological consequences. Türkiye, a biodiversity-rich country bridging Europe and Asia, has increasingly become a point of concern due to the rising presence of alien crayfish taxa introduced primarily via the aquarium trade and scientific research. This study investigates the presence records of nonnative crayfish species in Türkiye, identifies their likely introduction pathways, and outlines potential future outspread routes across the major freshwater basins of the country. Species such as Procambarus clarkii, Cherax quadricarinatus, C. albertisii, and Cambarellus patzcuarensis have …

Stage-Specific Growth Characteristics Of The Calanoid Copepod Invader Sinodiaptomus Sarsi​, Leonid Svetlichny, Kami̇l Mert Eryalçin, Melek İşi̇ni̇bi̇li̇r Okyar

Turkish Journal of Zoology

The population dynamics of the Asian invasive copepod Sinodiaptomus sarsi were  studied for four years after its introduction into an artificial pond in Kyiv (Ukraine) in  2020. The growth and development parameters of this species were measured under  laboratory conditions. From its first appearance in spring 2020, the abundance  of copepodite stages and adults increased from 3.5–5.2 individuals (ind.)  m–3 to 1057.8 ind. m–3 in June 2024, suggesting the successful establishment  of S. sarsi populations in this region. A characteristic feature of S.  sarsi development in ponds is a male-biased sex ratio in the later copepodite stages.  The sex ratio …

Morphometric And Reproductive Divergence Of Deep-Water Shrimps Plesionika Martia (A. Milne-Edwards, 1883) And P. Heterocarpus (A. Costa, 1871) Along A Depth Gradient In The Eastern Aegean Sea, Murat Özbek, Cengi̇z Koçak, Zafer Tosunoğlu

Turkish Journal of Zoology

This study provides a comparative analysis of two deep-water pandalid shrimp  species, Plesionika martia and P. heterocarpus, based on monthly samples collected  over one year in the Eastern Aegean Sea. Specimens were obtained from species-specific depth zones (550 m for P. martia and 350 m for P. heterocarpus) to examine  morphometric traits, sexual dimorphism, and reproductive patterns. A total of 4419  individuals were analyzed. Females were significantly larger and more abundant than  males (K–S test, p < 0.05), indicating pronounced sexual dimorphism. Length–weight relationships revealed negative allometric growth in both species, confirmed  by t-tests (p < 0.05). Reproductive activity differed markedly: P. martia showed a short  and distinct spawning period peaking in late autumn, whereas P. heterocarpus  displayed a prolonged, bimodal cycle with peaks in spring and summer. The gonadosomatic index (GSI) and the proportion of ovigerous females varied  significantly by season and species. A strong positive correlation between carapace  length and gonad weight was found, with a more linear relationship in P. martia and  greater variability in P. heterocarpus. Size at first maturity (L₅₀) was estimated at 22.3  mm CL for P. heterocarpus but could not be reliably determined for P. martia  due to limited small size data, likely reflecting ontogenetic depth segregation. The  consistent bathymetric separation between these species—also reported in the  Western Mediterranean—suggests ecological niche differentiation. Species-specific  management measures, including depth-based fishing restrictions and temporal  closures during reproductive peaks, are recommended to support the sustainable  exploitation of deep sea shrimp stocks in the region.

Frequencies And Roles Of Plants In The Diet Of Three Mesocarnivores (Canis Lupaster, Genetta Genetta, And Herpestes Ichneumon): Implications For Forest Regeneration In A North African Hot Spot (Algeria), Messaoud Bensidhoum, Abdelkrim Limane, Larbi Khifer, Ania Ben Ammar, Lylia Amrouche

Turkish Journal of Zoology

The Djurdjura National Park (PND, Algeria) is part of one of the world’s 36 biodiversity hot spots, recognised by the United Nations as a national biosphere  reserve. It contains the Darna primary forest, a key habitat for several mesocarnivore  mammals, including the golden wolf (Canis lupaster), the common genet (Genetta  genetta) and the ichneumon mongoose (Herpestes ichneumon). Although their diets  are primarily based on animal prey, these carnivores exhibit both qualitative and  quantitative reliance on plants, a pattern that merits thorough documentation. We  analysed 30 scats per species per month over four years (1440 scats per species).  More than 35% …

Examining The Association Between Awareness Of Soil Ecosystem Services And Yard Management In A Highly Urbanized And Tropical Watershed, Luis Kidany Selles, Elvia J. Melendez_Ackerman

Cities and the Environment (CATE)

Residential soil should be viewed as vital elements for sustainable cities. Of concern is that residents can be managing residential green spaces without a clear understanding of soil benefits. We performed 275 surveys in the Rio Piedras Watershed, Puerto Rico to evaluate: (1) the level of residents’ awareness about the contribution of soils to ecosystem services, and (2) the association between yard management practices with household socioeconomics and the level of residents’ awareness regarding residential soil ecosystem services. Results showed that residents were significantly less aware of the importance of soil ecosystem services in their yards compared to that of …

The Anthropology Of Life: An Interview With Perig Pitrou, Perig Pitrou, Tomas De Oliveira, Maddalena Canna

Transatlantic Forum

This interview focuses on the proposal for an "anthropology of life" developed by Perig Pitrou. The conversation traces the origins of this framework to fieldwork with the Mixe of Mexico, where rituals involving the metaperson "He Who Makes Being Alive" revealed a crucial distinction between "the living" (living beings) and "life" (the causes that make them alive). This separation underpins a comparative model examining how societies socialize two fundamental dimensions: the power to generate life and the fragility of individual existences. Methodologically, the approach draws on the anthropology of techniques, employing the concept of "agentive configurations" to analyze how humans …

Laughing Doves Use Human Structures In Fragmented Habitats To Improve Breeding Success, Humphrey Tietaah Ankuor, Ziblim Abukari Imoro, Timothy Khan Aikins

Cities and the Environment (CATE)

The effects of urbanisation on our natural environment have led to a significant shift in ecosystem structure and processes, posing threats to many wildlife species. However other species adapts to urban settings exploiting food and nesting opportunities that humans provide. This study identified and mapped Laughing Dove Streptopelia senegalensis nests in human structures and trees within in an urban setting. The study characterised the nesting site selection, nest materials choices, and breeding success in human structures and trees. The results show that majority (107 nests, 86%) of the Laughing Dove nests were in human structures with only 14% (16 nests) …

Using Spiderwebs To Capture Airborne Environmental Dna (Edna) To Detect Animal Biodiversity In An Urban Park, Sabriya Ann Seid, Leonardo Gonzalez-Smith, Josephine Campos, Demian A. Willette

Cities and the Environment (CATE)

Environmental DNA (eDNA) is the genetic material shed by organisms in the environment. It has emerged as a powerful resource for assessing biodiversity, particularly in aquatic settings. The application of eDNA methods in terrestrial environments is less developed, with researchers still exploring collection methods of eDNA from the air. One novel approach recently trialed is the use of spiderwebs, a passive, natural material whose sticky silk threads can capture tiny airborne particles, including eDNA. Here, we investigated the use of spiderwebs for airborne eDNA collection as part of a broader survey of biodiversity at the urban Ascot Hills Park in …

Perioperative Vasopressors In Free-Flap Maxillofacial Procedures, Merry K. Otte, Lauren Barnes

Group: Samford University Moffett & Sanders School of Nursing

Traditionally, vasopressors are avoided in microvascular surgery. This tradition is largely based on animal studies, which demonstrated that ephedrine and phenylephrine may lead to decreased graft perfusion and pedicle thrombosis. Modern clinical evidence is largely unable to replicate these results, as no consistent correlation is observed between flap compromise and vasopressor use. Although some isolated studies show potential flap compromise with vasopressor exposure, the vast majority of modern clinical evidence suggests that vasopressor exposure poses no increased risk to flap compromise.

Liberal fluid administration is the traditional approach to hemodynamic management during microvascular surgery, however, modern clinical evidence suggests that …

Culvert Retrofit With Green Filter Media For The Removal Of Phosphorus From Stormwater Runoff, Somdipta Bagchi, Zhiming Zhang, Olayinka Olayiwola, Bharadwaj Mandala, Rupali Datta, Subhasis Giri, Richard Lathrop, Dibyendu Sarkar

Michigan Tech Publications

Phosphorus is a ubiquitous contaminant in urban and agricultural landscapes. A retention basin located in the southern part of Barnegat Bay, New Jersey, was identified as receiving stormwater runoff with elevated phosphorus concentrations. The basin is surrounded by expanding urban development, contributing to the progressive degradation of water quality in the bay, which is already highly eutrophic. This study evaluated the effectiveness of a culvert retrofit with a green filter media composed of granulated-aluminum-based drinking water-treatment residuals (Al-WTR) and granular carbon (5:1 ratio, w/w) for the removal of phosphorus and suspended sediments from stormwater runoff. The performance of the filter …
