The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Genetic group and heterosis on morphometric measurements during the growth of male beef cattle

open access: yesSemina: Ciências Agrárias, 2016
In the present study, the effects of genetic group and heterosis on body measurements of purebreds (Charolais - C and Nellore - N), first-generation crossbreds (G1) (1/2C1/2N and 1/2N1/2C), and second-generation crossbreds (G2) (3/4C1/4N and 3/4N1/4C ...

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

open access: yesBiological Reviews, EarlyView.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

The Contingent Eco‐Innovation–Firm Performance Link: A Global Systematic Literature Review and Future Research Agenda

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The relationship between eco‐innovation (EI) and firm performance (FP) is central to environmental management research, yet empirical evidence remains fragmented and highly context dependent. This article presents a global systematic literature review (SLR) of 541 empirical studies (2006–April 2025) to (i) diagnose the systematic sources of ...

Understanding contingency in wolf‐mediated livestock predation across a mosaic of land uses: An agent‐based modelling approach

open access: yesPeople and Nature, EarlyView.
Abstract The return of grey wolves to multi‐use landscapes in North America and Europe raises concerns over accompanying risks of livestock predation. While local‐level risk factors have received attention, it is difficult to explore the role that landscape‐scale variables, such as landscape connectivity, play in driving livestock losses.

Assessment of cow and farm level risk factors associated with Ureaplasma diversum in pasture-based dairy systems - A field study

open access: yesAnais da Academia Brasileira de Ciências, 2017
Potential risk factors for Ureaplasma diversum in the vaginal mucus of 1,238 dairy cows were included in a multivariate logistic regression model, based on the cow level (i.e., granular vulvovaginitis [+GVV], yearly milk production [4500 kg or more ...

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.
