The Hope College Department Of Biology: The First 50+ Years, Christopher C. Barney
Faculty Publications
The Hope College Department of Biology was founded in 1899 with the appointment of the first Professor of Biology at Hope, Samuel Mast. During the first 50+ years of the Biology Department, there were eight total faculty members in the department, including Frances Koeman, the first female faculty member in the natural sciences. Four faculty members, Mast, Frank Patterson, Oscar Thompson, and Teunis Vergeer were primarily responsible for developing the department’s curriculum and programs, with Mast and Vergeer also carrying out published research. The department was housed primarily in Van Raalte Hall and the Science Building (now Lubbers Hall) for …
Recent Advances In The Juvenile-To-Adult Phase Transition, Yifei Liao, Mingli Xu
Recent Advances In The Juvenile-To-Adult Phase Transition, Yifei Liao, Mingli Xu
Faculty Publications
The transition from the juvenile to adult vegetative phase in Arabidopsis thaliana is a fundamental developmental process that integrates morphological and physiological maturation. Despite extensive study, how vegetative phase change is regulated and how this phase transition is coordinated with plant physiology remain incompletely understood. This review synthesizes recent advances in the molecular regulation and physiological functions of vegetative phase change. We summarize how developmental traits—such as leaf shape, trichome distribution, and margin serration—are controlled through distinct downstream targets of the age-dependent miR156–SPL pathway. We further highlight emerging insights into how epigenetic factors dynamically modify chromatin states of key regulatory …

Faculty Publications
The atomic bombings of Hiroshima and Nagasaki in 1945 created a unique environment of acute, high-dose ionizing radiation, contrasting sharply with the chronic low-dose rate exposure in the Chernobyl and Fukushima Exclusion Zones. This stands in stark contrast to the chronic, low-dose rate contamination that defines the Chernobyl and Fukushima Exclusion Zones. While the long-term ecological effects of the latter are well-documented, a systematic synthesis of the floral response to the atomic bombings is lacking. This review integrates historical data with modern radio-ecological principles to analyze plant survival and succession. We document the remarkable recovery of vegetation, from the resprouting …

Wrky Transcription Factors: Integral Regulators Of Defence Responses To Biotic Stress In Crops, Dongjiao Wang, Ruize Zhang, Wenhui Zou, Yuanyuan Zhang, Wanying Zhao, Tingting Sun, Qibin Wu, Zheng Qing Fu, Youxiong Que
Faculty Publications
Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant-specific and functionally diverse family that is central to immune regulation. Recent advances in genomic resources and multi-omics approaches have accelerated the identification and functional characterisation of WRKYs in crops. This review summarises the structural features and classification of WRKY genes and their genome-wide distribution across crop species. It also synthesises WRKY-centred regulatory modules that mediate resistance to major classes of biotic stress. In antifungal defence, WRKYs reinforce pattern- and effector-triggered …

Faculty Publications
Plants deploy sophisticated adaptive mechanisms to mitigate the detrimental effects of abiotic stresses (drought, salinity, temperature extremes, and heavy metals) and biotic stresses (pathogens and senescence) on growth and productivity. Central to these responses are transcription factors (TFs) that orchestrate stress-responsive gene networks. Among TF families, MADS-box proteins, characterized by their evolutionarily conserved DNA-binding domain, function as pivotal regulators of developmental plasticity and stress adaptation. While recent advances have clarified their roles in abiotic stress tolerance, a systematic integration of their functions in biotic stress responses has yet to be achieved. This review synthesizes current knowledge on how MADS-box TFs …

New Species Of Kronosvirus Bacteriophages That Infect Caulobacter Strain Cbr1, Tannaz Mohammadi, Austin Millwood, Maherah Shaik, Bert Ely
Faculty Publications
Caulobacter segnis strain CBR1 enhances the germination rate and total biomass of Arabidopsis plants. Since bacteriophages are usually present in the rhizosphere, we isolated three additional bacteriophages, designated TMCBR2, TMCBR3, and W2, that can replicate using CBR1 as the host strain. The genome sizes and morphologies of the new phages were similar to those of the previously isolated Kronos phage, and when we compared the nucleotide sequence of these new phage genomes, we found only minor differences among the four phage genomes. Pairwise sequence comparisons indicated that the phage genomes should be grouped into three separate species within Kronosvirus genus. …
Regulation Of Zygotic Genome Activation By The Nucleocytoplasmic Ratio, Lily Acker, Hui Chen
Regulation Of Zygotic Genome Activation By The Nucleocytoplasmic Ratio, Lily Acker, Hui Chen
Faculty Publications
During early development, embryos undergo the maternal-to-zygotic transition (MZT), when control of development shifts from maternal factors to the newly activated zygotic genome. Decades of studies in various model organisms suggest that the nucleocytoplasmic (N/C) ratio is a key regulator of zygotic genome activation (ZGA), though this relationship is more nuanced in some organisms than others. Changing the nuclear content, nucleus size or cell size has been shown to shift the timing of ZGA. Mechanistically, the N/C ratio is linked to fundamental cellular processes that regulate genome activities, including nuclear import, repressor titration, activator accumulation, cell cycle lengthening, and chromatin …

Open data and code are crucial to increasing transparency and reproducibility, and in building trust in scientific research. However, despite an increasing number of journals in ecology and evolutionary biology mandating for data and code to be archived alongside published articles, the amount and quality of archived data and code, and subsequent reproducibility of results, has remained worryingly low. As a result, a handful of journals have recruited dedicated data editors, whose role is to help authors increase the overall quality of archived data and code. There is, however, a general lack of consensus around what a data editor should …
Demography And Dispersal Influence The Relationship Between Habitat Suitability And Population Density, Cleber Ten Caten, Tad Dallas
Demography And Dispersal Influence The Relationship Between Habitat Suitability And Population Density, Cleber Ten Caten, Tad Dallas
Faculty Publications
A central goal of ecology is to understand spatial patterns of species densities. Habitat suitability estimates from species distribution models (SDMs) could be used to represent species density and overcome the scarcity of density data. However, there is mixed evidence that habitat suitability is a reliable descriptor of density, and it is suggested that local dynamics affect the relationship between habitat suitability and density. We simulated population dynamics for 200 virtual species considering different combinations of factors (demographic stochasticity, dispersal, and intraspecific competition) that affect population sizes and SDMs were trained using different sets of environmental predictors to evaluate when …
Paternal Effects Without Paternity? Testing Non-Genetic Male Influence On Offspring Size And Brood Size In A Gynogenetic Vertebrate, The Amazon Molly (Poecilia Formosa), Ulrike Scherer, Sean Ehlman, David Bierbach, Jens Krause, Max Wolf
Paternal Effects Without Paternity? Testing Non-Genetic Male Influence On Offspring Size And Brood Size In A Gynogenetic Vertebrate, The Amazon Molly (Poecilia Formosa), Ulrike Scherer, Sean Ehlman, David Bierbach, Jens Krause, Max Wolf
Faculty Publications
Paternal effects, i.e., effects of fathers on the phenotype of their offspring that are not mediated by the transmission of alleles, are increasingly recognized as a potentially significant source of phenotypic variation across taxa – even in the absence of paternal care. Gynogenetic systems, which rely on sperm to trigger embryogenesis without incorporating male genetic material, provide a powerful way to experimentally isolate paternal effects from effects caused by the integration of male genetic material. Up to now, however, paternal effects remain largely unexplored in these systems. Here, we tested for non-genetic paternal effects in the gynogenetic Amazon molly ( …

On-Orbit Correction Of Ecostress Radiances By Comparison With Iasi Hyperspectral Sounders, David S. Wethey, Sarah A. Woodin, Jorge Vazquez-Cuervo
Faculty Publications
Radiance data from ECOSTRESS (ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station), which is the first of a planned virtual constellation of wide-swath ultra-high-resolution thermal satellites, were used to test the concept of on-orbit cross-calibration based on the Global Space-based Inter-Calibration System (GSICS) with the Infrared Atmospheric Sounding Interferometer (IASI) as the reference. Validation of the results was performed using comparisons of corrected ECOSTRESS radiances with strictly independent data from IASI and the Cross-Track Infrared Sounder (CrIS) and with RTTOV radiative transfer simulations of clear-sky observations in iQuam (the NOAA in situ sea surface temperature quality monitor database). ECOSTRESS has …

Structural And Mechanical Properties Facilitate Shock Wave Damping By Helmet-Like Orbital Hoods In Snapping Shrimp, Mia Kazel, Rebekah E. Cammack, Alexandra C.N. Kingston, Ahmed A. Alshareef, Tarek Shazly, Daniel Isaac Speiser
Faculty Publications
Snapping shrimp damp the shock waves they produce and use as weapons with a helmet-like structure termed the orbital hood. Here, we ask how structural and material properties contribute to shock wave damping by orbital hoods in Alpheus heterochaelis. Using tensile mechanical testing, we find orbital hoods are approximately half as stiff as carapace and have twice the capacity for viscous energy dissipation. Microstructural features probably contribute to tissue-specific mechanical properties: the endocuticles of orbital hoods have almost twice as many lamellae as those of carapaces despite being half as thick, suggesting a mechanism for enhanced material mobility underlying …

Nanomedicine Meets Immunotherapy: Transforming Chimeric Antigen Receptor T Cell Treatment For Solid Tumors, Stephen O'Rourke, Nuo Xu, Hongjun Wang, Hexin Chen
Faculty Publications
The emergence of effective immunotherapies has drastically revolutionized clinical management of many cancer types. Among them, chimeric antigen receptor (CAR)-T cell therapy (CTT), as a groundbreaking approach, has been considered as a “living drug,” displaying unprecedented clinical outcomes with hematological malignancies, including B cell leukemia and lymphomas, and multiple myeloma. Despite the high remission rates and improved survival achieved with hematological cancers, the effectiveness of CTT in solid tumors remains largely unsatisfactory. The efficacy of CTT in solid tumors is significantly challenged by multiple factors, including tumor-antigen heterogeneity, limited T cell trafficking and infiltration, a highly immunosuppressive tumor microenvironment, and …

Community Synchrony In Aquatic Macroinvertebrates Is Unrelated To Environmental Variability But Differs Among Functional Feeding Groups, Anthony J. Pignatelli, Tad Dallas
Faculty Publications
Environments are becoming increasingly more variable, as a function of climate change. As this occurs, species may be exposed to conditions outside their preferred range. Such variability in the environment can influence community abundance as individual species respond either similarly (synchronous dynamics) or differently (asynchronous dynamics) to each other. These fluctuations in abundances are important for understanding the impact of environmental variability on species temporal fluctuations in aquatic macroinvertebrates. This group of organisms is species-rich and highly sensitive to environmental fluctuations. We analyzed 18 stream macroinvertebrate communities sampled by the National Ecological Observatory Network between 2014 and2022 to understand how …

Myeloid cells are highly heterogeneous and play key roles in establishing an immunosuppressive tumor microenvironment (TME), but the mechanisms controlling their differentiation remain unclear. Using orthotopic murine breast cancer models, we investigated how interleukin-1α (IL-1α) influences this process. Deletion of host Il1α resulted in rejection of transplanted tumors. Single-cell RNA sequencing identified CX3CR1⁺ macrophages as the main source of IL-1α in the TME. Il1α deficiency disrupted monocyte–macrophage differentiation, reducing CX3CR1⁺ macrophages and increasing iNOS⁺ macrophages. Myeloid cells from Il1α⁻/⁻ hosts induced lower PD-1 and CTLA-4 expression in co-cultured CD8⁺ T cells than those from wild-type hosts. CellChat analysis showed …

Regeneration Of Swimming Antennae After Partial Amputation In Long- And Short-Lived Daphnia, Charles Schumpert, Rekha C. Patel, Jeffry L. Dudycha
Faculty Publications
Regeneration, the ability of an animal to restart a developmental process and thus rebuild itself following injury or loss, is generally thought to be inversely related to aging, the progressive decline of organismal functions and fitness that occurs as adults get older. We sought to test whether recently evolved differences of aging in the crustacean Daphnia were accompanied by evolutionary divergence of regenerative ability. Using the short-lived D. pulex and the long-lived D. pulicaria, we conducted an assessment of regenerative ability in which we amputated part of the swimming antenna and observed subsequent regeneration. In four clones isolated from …

Wheat stripe rust (Puccinia striiformis f. sp. tritici, Pst) poses a catastrophic threat to global food security. While MADS-box transcription factors regulate development and abiotic stress, their roles in plant-pathogen immunity remain enigmatic. In this study, we identified TaMADS2, a Pst-induced MADS-box gene, as a positive regulator of wheat resistance. Functional analyses demonstrated that TaMADS2 overexpression significantly enhanced Pst resistance, whereas its knockdown rendered wheat more susceptible. Further investigation revealed that TaMADS2 interacts with trichome birefringence-like protein 21 (TaTBL21) to activate glycerol kinase-like (TaGKL) expression. Silencing TaGKL in wild-type or TaMADS2-overexpressing lines …

The small GTPase CDC42 promotes axon growth through actin filament polymerization and this growth is driven by axonal localization of the mRNA encoding the prenylated CDC42 isoform (Prenyl-Cdc42). Here, we show that axonal Prenyl-Cdc42 mRNA levels and the mRNA’s translation are decreased by growth-inhibiting stimulation and increased by growth-promoting stimulation. In contrast, axonal RhoA mRNA transport and translation are increased by growth-inhibiting but unaffected by growth-promoting stimuli. Localized increase in KHSRP in response to growth inhibitory stimulation, through elevation of intracellular Ca2+, promotes decrease in axonal levels of Prenyl-Cdc42 mRNA. Distinct 3’UTR motifs regulate transport and …

The application of satellite-derived sea surface temperature in coastal regions is critical for resolving the dynamics of frontal features and coastal upwelling. Here, we examine and compare sea surface temperature (SST) gradients derived from two satellite products, the Multi-Scale Ultra-High Resolution SST Product (MUR, 0.01° grid scale) and the Operational SST and Ice Analysis (OSTIA, 0.05° grid scale), available through the Group for High Resolution SST (GHRSST). Both products show similar seasonal variability, with maxima occurring in the summer time frame. Additionally, both products show an increasing trend of SST gradients near the coast. However, differences exist between the two …

Radioactive Contamination And Climate Warming Affect Physiological Performance Of Chornobyl Barn Swallows, Zbyszek Boratyríski, Timothy Mousseau, Anders Pape Møller
Faculty Publications
Global warming and degradation of natural habitats are the two main factors causing ecophysiological stress on individuals and risk for biodiversity. Hyperthermia is a common response to stress in homeothermic animals, in particular to heat, pathogens and environmental contamination. Resilience of biological systems to global warming may be deteriorated in polluted habitats. Here we investigated how body temperature of a wild bird, the barn swallow (Hirundo rustica), responded to global warming while simultaneously exposed to radioactive contamination from the Chernobyl accident. Our results showed that both high air temperatures (t = 15.55, df = 335, p < 0.0001) and elevated environmental radioactive contamination (t = 5.18, df = 8.09, p = 0.0008) increased internal body temperature of individuals. The additive effect suggests that birds might suffer hyperthermia in locally contaminated habitat (1.47% body temperature increase) while simultaneously exposed to globally rising temperatures (1.95% body temperature increase), potentially reducing the fitness of individual and the maintenance of breeding colonies. The cumulative and interactive negative effects of multiple stressors, such as those emerging from increasing habitat degradation and climate change, will likely contribute to biodiversity losses globally.

To characterize society’s contribution to the global soundscapes, we used passive acoustic recorders at 139 sites across 6 continents, sampling both urban green spaces and nearby pristine sites continuously for 3 years in a paired design. Recordings were characterized by bird species richness and by 14 complementary acoustic indices. By relating each index to seasonal, diurnal, climatic and anthropogenic factors, we show here that latitude, time of day and day of year …
