Spatial factors overcome seasonality in increasing the consumption of allochthonous food resources by fishes from tropical lotic ecosystems

Vitor Manuel Barros Ferreira, Bruno Eleres Soares, Juliana Silva Leal, et al.

Published: 2023-03-15
Subjects: Biodiversity, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology

1. In lotic ecosystems, it is expected higher availability of allochthonous food resources during floods and rainfall events, which may yield a higher consumption of these resources by consumers. However, both the allochthonous input in aquatic ecosystems and seasonality in environmental conditions are locally dependent, thus dietary responses of freshwater consumers to seasonality should also be [...]

A probabilistic approach to estimating timber harvest location

Determining the harvest location of timber is crucial to enforcing international regulations designed to protect natural resources and to tackle illegal logging and associated trade in forest products. Stable Isotope Ratio Analysis (SIRA) can be used to verify claims of timber harvest location by matching levels of naturally-occurring stable isotopes within wood tissue to location-specific ratios [...]

How to do biodiversity-related science communication

Jonas Geschke, Matthias C. Rillig, Katrin Böhning-Gaese, et al.

Published: 2023-02-20
Subjects: Biodiversity, Communication, International and Intercultural Communication

Biodiversity is the foundation of our lives. Yet we destroy ecosystems and drive species to extinction. Human-induced biodiversity loss does not yet receive sufficient public attention, although biodiversity is fundamental for dealing with global environmental crises. Effective communication of biodiversity-related knowledge is challenging but crucial and should contribute to evidence-based [...]

The missing link: discerning true from false negatives when sampling species interaction networks

Michael D Catchen, Timothée Poisot, Laura J. Pollock, et al.

Published: 2023-01-19
Subjects: Applied Statistics, Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring

Ecosystems are composed of networks of interacting species. These interactions allow communities of species to persist through time through both neutral and adaptive processes. Despite their importance, a robust understanding of (and ability to predict and forecast) interactions among species remains elusive. This knowledge-gap is largely driven by a shortfall of data—although species occurrence [...]

Habitat destruction threatens jaguars in a mixed land use region of eastern Bolivia

René Meißner, Moritz Blumer, Merlin Weiß, et al.

Published: 2022-12-14
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Zoology

Large carnivores such as the jaguar (Panthera onca) are particularly susceptible to population decline and local extinction as a result of habitat loss. Here, we report on the long-term monitoring of a local jaguar population in a mixed land use area in the eastern lowlands of Bolivia from March 2017 to December 2019. We recorded 15 jaguar individuals and four reproduction events (five offspring [...]

Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Evolution, Genomics, Life Sciences, Other Ecology and Evolutionary Biology

In the last decade and a half, advances in genetic sequencing technologies have revolutionized systematics, transforming the field as studying morphological characters; a few genetic markers have given way to genomic data sets in the phylogenomic era. A plethora of molecular phylogenetic studies on many taxonomic groups have come about, converging on, or refuting prevailing morphology or [...]

Hybridization boosters diversification in a Neotropical orchid group

Cecilia F. Fiorini, Eric de Camargo Smidt, L. Lacey Knowles, et al.

Published: 2022-12-14
Subjects: Biodiversity, Genomics, Other Ecology and Evolutionary Biology, Plant Biology, Population Biology

Genetic data shows that cryptic hybrids are more common than previously thought and that hybridization and introgression are widespread processes in nature. Regardless of this, studies on hybridization are scarce for the highly speciose Bulbophyllum. The genus presents more than 2,200 species and many examples of recent radiations, in which hybridization is expected to be frequent. Currently, [...]

Understanding local plant extinctions before it’s too late: bridging evolutionary genomics with global ecology.

Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Plant Sciences

Understanding evolutionary genomic and population processes within a species range is key to anticipating the extinction of plant species before it is too late. However, most models of biodiversity risk projections under global change do not account for the genetic variation and local adaptation of different populations. Population diversity is critical to understanding extinction because [...]

Plant traits poorly predict winner and loser shrub species in a warming tundra biome

Mariana García Criado, Isla H. Myers-Smith, Anne D. Bjorkman, et al.

Published: 2022-11-30
Subjects: Biodiversity, Plant Biology, Terrestrial and Aquatic Ecology

Climate change is leading to a species redistributions. In the tundra biome, many shrub species are expanding into new areas, a process known as shrubification. However, not all tundra shrub species will benefit from warming. Winner and loser species (those projected to expand and contract their ranges, and/or those that have increased or decreased in cover over time), and the characteristics [...]

Accounting for cloud cover and circannual variation puts the effect of lunar phase on deer-vehicle collisions into perspective

Jacopo Cerri, Laura Stendardi, Elena Bužan, et al.

Published: 2022-11-22
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Zoology

Although several studies have focused on the influence of moonlight over deer-vehicle collisions, findings have been inconsistent. This may be due to neglecting the effects of cloud cover, a major impediment to moon illumination, and circannual variation in both deer and human activity. We modeled how median cloud cover interacted with the illuminated fraction of the moon in affecting daily roe [...]

Typification of plants illustrated by Feuillée: a reply to Zanotti et al.

Mark Alan Hershkovitz

Published: 2022-11-18
Subjects: Biodiversity

ABSTRACT: Zanotti et al. (2022a) lectotypified Gnaphalium viravira Feuillée ex Molina with its illustration in Feuillée (1725). They concluded that this illustration qualified as original material seen by Molina (1782). However, Hershkovitz (2020a, b) had concluded that Molina had not seen any of the illustrations in Feuillée (1725), thus none qualify as original material for taxa he validly [...]

The cost of being a non-native English speaker in science

Tatsuya Amano, Valeria Ramírez-Castañeda, Violeta Berdejo-Espinola, et al.

Published: 2022-11-10

The use of English as the common language of science represents a major impediment to maximising the contribution of non-native English speakers to science. Yet few studies have quantified the consequences of language barriers on the career development of researchers who are non-native English speakers. Our survey demonstrates that non-native English speakers, especially early in their careers, [...]

Elia van Tongeren, Ginevra Sistri, Vincenzo Zingaro, et al.

Published: 2022-11-03
Subjects: Biodiversity, Entomology, Life Sciences, Zoology

Aesthetic attractivity stands as an underestimated yet fundamental feature of species in conservation biology, significantly driving disproportionate protection efforts towards charismatic species. Despite the evidence, few attempts sought to precisely quantify the impact of aesthetic attractivity in defining priority of species for conservation actions (e.g. inclusion in International Union for [...]
