Data from: Contrasting sap flow characteristics between pioneer and late-successional tree species in secondary tropical montane forests of Eastern Himalaya, India
Abstract The interactive role of life-history traits and environmental forcing on plant-water relations is crucial for understanding species response to climate change but remains poorly understood in secondary tropical montane forests (TMFs). Comparing contrasting life-history traits (pioneer vs late-successional species) in a biodiverse Eastern Himalayan secondary TMF, we investigated sap flow responses in co-occurring pioneer species, Symplocos racemosa (n=5) and Eurya acuminata (n=5), and late-successional species, Castanopsis hystrix (n=3), using modified Granier's Thermal Dissipation probes. The fast-growing pioneers S. racemosa and E. acuminata) had 2.1- and 1.6-times higher sap flux density than the late-successional C. hystrix, respectively, and exhibited characteristics of long-lived pioneer species. Significant radial and azimuthal variability in sap flow (V) between species was observed and attributed to life history traits and the canopy's access to sunlight. Nocturnal V (1800-0500 hr) was 13.8 % of daily V and is attributed to stem recharge for evening V (1800-2300 hr) and to endogenous stomatal controls for pre-dawn V (0000-0500 hr). Both the shallow-rooted pioneer species exhibited midday depression in V attributed to photosensitivity and diel moisture stress response. In contrast, deep-rooted C. hystrix transpired unaffected across the dry season likely accessing groundwater. Thus, the secondary broadleaved TMFs, with the dominance of shallow-rooted pioneers, are more prone to the negative impacts of drier and warmer winters than primary forests, which are dominated by deep-rooted species. The study provides an empirical understanding of life-history traits and microclimate modulating plant-water use in widely distributed secondary TMFs in Eastern Himalaya and highlights their vulnerability against warmer winters and reduced snowfall due to climate change.
Data for Reserach titled "Exploring Scientific Reasoning and Genetics Self-efficacy as Predictors of Secondary School Students' Achievement in Genetics Concepts"
<p>This dataset is for the research article titled Exploring Scientific Reasoning and Genetics Self-efficacy as Predictors of Secondary School Students’ Achievement in Genetics Concepts. The data were collected using three instruments (Lawson’s Classroom Test of Scientific Reasoning (r = 0.76), adopted from the Lawson's Classroom Test of Scientific Reasoning designed by Lawson in 2000; Self-efficacy in Genetics Concepts Scale (@ = 0.88),adapted from Schwarzer and Jerusalem (1995) General Self Efficacy Scale and Biology Self-Efficacy developed by Baldwin, Ebert-May and Burns (1999); and Students’ Achievement Test in Genetics Concepts (r = 0.78), self-designed by the athors) from 336 Secondary School Two (SS2) biology students selected from nine secondary schools randomly selected from three local government areas in Oyo State. SPSS version 26 was employed as the statitsical software, while data collected were subjected to mean, standard deviation, percentages, ANOVA and Multiple regression analysis at 0.05 level of significance.</p>

Vertically inherited microbiota and environment-modifying behaviors indirectly shape the exaggeration of secondary sexual traits in the gazelle dung beetle
<p><span>Many organisms actively manipulate the environment</span><span> in ways that have the potential to feed back on their own development, a process referred to as developmental niche construction</span><span>. Yet, </span><span>the role that constructed biotic and abiotic environments play in shaping phenotypic variation and its evolution is insufficiently understood. Here, we assess whether environmental modifications made by developing dung beetles impact the environment-sensitive expression of secondary sexual traits</span><span>.</span> <span>Larval gazelle dung beetles both physically modify their ontogenetic environment and structure their biotic interactions through the vertical inheritance of microbial symbionts. By experimentally eliminating i) physical environmental modifications, and ii) the vertical inheritance of microbes, we assess the degree to which (sym)biotic and physical environmental modifications shape the exaggeration of several traits </span><span>varying in their degree and direction of sexual dimorphism. We expected the experimental reduction of a larva's ability to shape its environment to affect trait size and scaling, especially for traits that are sexually dimorphic and environmentally plastic</span><span>. </span><span>We find that compromised developmental niche construction indeed shapes sexual dimorphism in overall body size and the absolute sizes of male-limited exaggerated head horns, the strongly sexually dimorphic fore tibia length and width, as well as the weakly dimorphic elytron length and width. This suggests that ontogenetic environmental modifications affect sex-specific phenotypic variation in functional traits. However, most of these effects can be attributed to nutrition-dependent plasticity in size and non-isometric trait scaling, rather than body-size-independent effects on the developmental regulation of trait size. Our findings suggest that the reciprocal relationship between developing organisms, their symbionts, and their environment can have considerable impacts on sexual dimorphism and functional morphology. </span></p>
Plant secondary metabolite increases the control-effectiveness of natural enemy - based on caffeine and Snellenius manilae
<p class="MsoNormal"><span>The food resources in the field can effectively strengthen the ability of natural enemies to control the pest. Certain compounds, in addition to carbohydrates and amino acids, may improve the physiological performance of insects. Caffeine, for instance, has been shown to enhance pollinator memory and physiological reactions. However, little is known about how caffeine influences parasitoids. The control effectiveness and survival rate of the parasitoid (</span><em>Snellenius manilae</em><span>) were tested in this study after the parasitoids were fed solutions with different concentrations of caffeine. We examined caffeine concentrations of 10</span><sup>-2</sup><span>, 10</span><sup>-4</sup><span>, and 10</span><sup>-6</sup><span> (M) mixed with a 25% sucrose solution and a pure sucrose solution as a control group. The results show that a concentration of 10</span><sup>-6</sup><span> caffeine solution significantly increased the parasitism rate of</span><em> S. manilae </em><span>by 10.76% when compared to the control group. Despite the significantly lower survival rate and male bias of </span><em>S. manilae </em><span>offspring in the 10</span><sup>-2</sup><span> treatment, no further negative responses in growth performance, development time, or cocoon weight were observed. These findings suggest that an appropriate concentration of caffeine solution can have a positive impact on the control effectiveness of parasitoids in the laborat</span>ory. Our results highlight the potential of secondary compounds to increase the bio-control effectiveness.</p>
