Molecular characterization of transformer, transformer‐2, and doublesex genes in the carambola fruit fly, Bactrocera carambolae, revealing potential for genetic pest management

Insect Science, EarlyView.
Abstract Globalization and climate change may be driving the spread of the quarantine fruit fly, Bactrocera carambolae, highlighting the need for ecofriendly control methods like the Sterile Insect Technique (SIT), which relies on releasing sterile males to reduce wild populations.

Ecological and social factors lead to variation in parental care between sexes in a burying beetle

Insect Science, EarlyView.
We experimentally investigated the effects of ecological (resource availability and interspecific competition) and social factors (intraspecific competition) on parental care and reproductive success in the burying beetle Nicrophorus vespilloides. Our results showed that males and females adjust their parental care based on resource availability and ...

A phylogenomic perspective on interspecific competition

Ecology Letters, 2023
AbstractEvolutionary processes may have substantial impacts on community assembly, but evidence for phylogenetic relatedness as a determinant of interspecific interaction strength remains mixed. In this perspective, we consider a possible role for discordance between gene trees and species trees in the interpretation of phylogenetic signal in studies ...

Selection and Interspecific Competition

1977
Other organisms constitute a component of the environment to which animals respond by natural selection. Among the different kinds of interspecific interactions, competition for common resources is attributed an important role in the evolution of the single species and for the structure of biological communities.

Interspecific competition, predation and species diversity

Journal of Theoretical Biology, 1970
Abstract A review was made of some mathematical population models and their applications to problems of interspecific competition and predator-prey relationships. These were considered in relation to some observations and experiments suggesting local increases in species diversity under predation in competitive situations.

Interspecific competition/facilitation among insect parasitoids

Current Opinion in Insect Science, 2016
Competition for limited resources is a widespread ecological interaction in animals. In the case of insect parasitoids, species can compete for host resources both at the adult stage as well as at the larval stage. Interspecific competition can play a role in sizing and shaping community structures.

Interspecific Competition Models Derived from Competition Among Individuals

Bulletin of Mathematical Biology, 2012
This paper demonstrates how discrete-time models describing population dynamics of two competing species can be derived in a bottom-up manner by considering competition for resources among individuals and the spatial distribution of individuals. The competition type of each species is assumed to be either scramble, contest, or an intermediate between ...

Interspecific Competition and Exploitation

Journal of the Fisheries Research Board of Canada, 1963
The consequences of exploitation of either or both of a pair of competing species are examined using the Lotka-Volterra equations. The removal of a fixed proportion of a population on an instantaneous basis shifts the equilibrium population sizes for both the exploited species and its competitor.

Interspecific competition in metapopulations

Biological Journal of the Linnean Society, 1991
The assumptions and predictions of metapopulation models for competing species are discussed in relation to empirical studies of colonization and extinction in metapopulations. In three species of Daphnia in rockpools, interspecific competition increased local extinction rates, while no effects on colonization rates were detected.
