1. Demographic correction—A tool for inference from individuals to populations

Author:
Adam Klimeš; Jitka Klimešová; Zdeněk Janovský; Tomáš Herben
Source:
Functional ecology 2022 v.36 no.5 pp. 1078-1086
ISSN:
0269-8463
Subject:
demography; environmental factors; population dynamics
Abstract:
... Estimation of responses of organisms to their environment using experimental manipulations, and comparison of such responses across sets of species, is one of the primary tools in ecology research. The most common approach is to compare the response of a single life stage of species to an environmental factor and use this information to draw conclusions about population dynamics of these species. ...

Anastrepha ludens; adulthood; adults; animals; body weight; carbohydrates; conspecificity; diet; food quality; frugivores; fruit flies; intraspecific competition; larvae; larval development; population dynamics; pupae
Abstract:
... Diet quality and the presence and abundance of conspecifics feeding on the same food resource are critical factors that affect functional traits of many animal species and influence ecological processes. We hypothesized that in insects whose larvae live in groups of varying sizes in ephemeral and nutritionally variable environments, extreme macronutrient content in the feeding substrate is a barri ...

Subject:
biomass production; colonizing ability; ecological invasion; grasshoppers; herbivores; introduced plants; invasive species; nutrient availability
Abstract:
... Numerous studies have highlighted the roles of nutrient availability and fluctuations therein for invasion success of alien plants. Many others also highlighted the role of herbivores in invasion success. However, how herbivory and the level and fluctuations in nutrient availability interact in driving alien plant invasion into native communities remains largely unexplored. We grew eight invasive ...

Subject:
adults; color; ecology; males; reproductive success; sexual selection
Abstract:
... Ornamental coloration is frequently an honest signal of quality associated with sexual selection. While changes in average environmental conditions affect carotenoid‐ and melanin‐based coloration, no evidence exists that changes in intrinsic environmental predictability affect coloration. Here we experimentally manipulated the intrinsic predictability of precipitation in semi‐natural populations o ...

Drosophila melanogaster; adults; body weight; diet; ecology; fecundity; fruits; life history; longevity; phenotype; progeny; sucrose; triacylglycerols
Abstract:
... Intergenerational effects on offspring phenotypes occur in response to variation in both maternal and paternal nutrition. Because the combined maternal and paternal effects are rarely considered together, however, their relative contributions, and the capacity for interactions between parental diets to shape offspring life history and physiology are not understood. To address this, we altered the ...

Abstract:
... Warming temperatures caused by climate change are predicted to vary temporally and spatially. For mid‐ and high‐latitude reptiles, the seasonal variation in warming temperatures experienced by embryos and hatchlings may determine offspring fitness, yet this has remained largely unexplored. To evaluate the independent and interactive influence of seasonal variation in warming temperatures on embryo ...

Abstract:
... Carbon (C) allocation strategy plays a critical role in plant adaptability, which are also important to assess the productivity stability under environmental change. Based on optimal partitioning theory, we asked two questions: (1) How is plant C allocation within tissues affected by nutrient enrichment (N addition)? And (2) does long‐term N addition alter how plants allocate C under drought? To a ...

Abstract:
... Insect egg micropyles are openings through the chorion allowing sperm entry for fertilisation. Micropyles are diverse structures showing remarkable variation in number, spatial arrangement and physical structure across extant insect orders. Despite being almost ubiquitous across insects, they have received little attention. As key morphological features of an immobile life stage, it is plausible t ...

Subject:
Pieris napi; butterflies; climate change; diapause; mortality; weight loss; winter
Abstract:
... Diapause is considered an important adaptation for survival of winter; however, insects often enter diapause long before its onset. Thus, diapausing insects must also be able to survive these prewinter conditions which warm temperatures could make quite energetically taxing despite relative inactivity. We tested for both immediate and delayed fitness effects of prewinter conditions in diapausing P ...

Gambusia affinis; allometry; body size; ecology; ectothermy; energy; excretion; metabolism; nitrogen; phenotypic plasticity; temperature
Abstract:
... Physiological rates are heavily dependent on temperature and body size. Most current predictions of organisms’ response to environmental warming are based on the assumption that key physiological rates such as metabolism and excretion scale independently with body size and temperature and will not evolve. However, temperature is a significant driver for phenotypic variability in the allometric sca ...

Abstract:
... Carbon isotope fingerprinting, or multivariate analysis using δ¹³C values of individual compounds, is a powerful tool in ecological studies, particularly measurements of essential amino acids (EAA δ¹³C). Despite the widespread application of this technique, there has been little methodological validation to determine (a) whether multivariate EAA δ¹³C signatures (fingerprints) of primary producer g ...

Abstract:
... The links between internal nitrogen recycling through the process of resorption from senescing leaves, whole‐plant resource‐use strategies and performance remain elusive. Indeed, tests of such potential linkages are hampered by the classical evaluation of plant nitrogen resorption efficiency (REN) based on ‘snapshots’ of leaf nitrogen concentration from adult and senescent leaves. We significantly ...

Soil biota are increasingly recognized as a primary control on litter decomposition at both local and regional scales, but the precise mechanisms by which biota influence litter decomposition have yet to be identified. There are multiple hypothesized mechanisms by which biotic communities may influence litter decomposition—for example, decomposer communities may be specially adapted to local litte ...

Abstract:
... Parasites kill hosts but also can indirectly increase the abundance of their resources. Given this resource feedback, how much will parasites decrease host density? Can they increase host density? Seeking answers, we integrate trait measurements, a resource–host–parasite model and experimental epidemics with plankton. This combination reveals how parasites may decrease or increase host density. Th ...
