Synergistic impacts of co-occurring invasive grasses cause persistent effects in the soil-plant system after selective removal

Rafael Zenni, Wanderson Da Cunha, Carolina Musso, Jocemara De Souza, Gabriela Nardoto & Heloisa Miranda
1. Human influence on the environment is so extensive that virtually all ecosystems on the planet are now affected by biological invasions. And, often, ecosystems are invaded by multiple co-occurring non-native species. Hence, it is important to understand the impacts these invasions are producing on biodiversity and ecosystem processes. 2. Here, we present results of a two-year long field experiment where we tested the effects of co-occurring invasive C4 African grasses in a Cerrado area...

Data from: Genetic evaluation of migratory fish: implications for conservation and stocking programs

Juliana Pimentel, Sandra Ludwig, Leonardo Resende, Pedro Brandão-Dias, Adriana Pereira, Nazaré Abreu, Izinara Rosse, Ana Paula Martins, Susanne Facchin, João Lopes, Gilmar Santos, Carlos Alves & Evanguedes Kalapothakis
Fish stocking programs have been implemented to mitigate the blockage of original riverbeds by the construction of hydropower dams, which affects the natural migration of fish populations. However, this method raises concerns regarding the genetic rescue of the original populations of migratory fish species. We present the first study to investigate the genetic diversity, population structure, and gene flow (migration) of the Neotropical migratory fish Prochilodus costatus in the Três Marias dam in São Francisco...

Python Script used in: Evolution of nuptial gifts and its coevolutionary dynamics with male-like persistence traits of females for multiple mating

Yoshitaka Kamimura, Kazunori Yoshizawa, Charles Lienhard, Rodrigo Ferreira & Jun Abe
Many male animals donate nutritive materials during courtship or mating to their female mates. Donation of large-sized gifts, though costly to prepare, can result in increased sperm transfer during mating and delayed remating of the females, resulting in a higher paternity. Nuptial gifting sometimes causes severe female-female competition for obtaining gifts (i.e., sex-role reversal in mate competition) and female polyandry, changing the intensity of sperm competition and the resultant paternity gains. We built a theoretical...

Climate and soil mediate the effects of liana density on forest dynamics

Vinícius Maia, Rubens Santos, Marco Aurélio Fontes, Alisson Santos, Natália De Aguiar-Campos, Cléber Rodrigo De Souza, Jean Daniel Morel, Matheus Coutinho Oliveira, Nathalle Cristine Alencar Fagundes & Fernanda Moreira Gianasi
Forest community dynamics is a topic of great interest in times when the global carbon budget is a widespread concern due to climate change. Among its effects, longer periods of drought and liana proliferation, coupled with land-use change, may endanger tropical forest carbon sinks. Here, in a 10.3 ha sampling of six Atlantic semideciduous forests, we investigated the effects of liana crown occupancy and large-stemmed lianas, as well as their interactions with climate and soil,...

Elements of fish metacommunity structure in Neotropical freshwater streams

Thiago Bernardi Vieira, Leandro Schlemmer Brasil, Liriann Chrisley Nascimento Da Silva, Francisco Leonardo Tejerina Garro, Pedro De Podestà Uchôa De Aquino, Paulo Santos Pompeu & Paulo De Marco
The identification of the mechanisms underlying co-occurrence patterns of species is a way to identify which processes (niche, neutral or both) structure metacommunities. In this paper, our goals are to identify patterns of co-occurrence in neotropical stream fish and determine which processes structure the metacommunity and the gradients that underlie this structure. Our results pointed out that the metacommunity formed by the total pool of species is structured by a nested pattern (Hyperdispersed Species Loss)...

Data from: Tough fishing and severe seasonal food insecurity in Amazonian flooded forests

Daniel Tregidgo, Jos Barlow, Paulo Pompeu & Luke Parry
Billions of people rely on harvesting wildlife for food, and must contend with catch rates that vary in space (e.g. overharvesting near communities) and time (e.g. seasonal migrations). Yet, research has overlooked potential linkages between reduced wildlife catch rates (catch-per-unit-effort) and food security. Moreover, assumptions that people living in biologically rich environments are food secure lack empirical testing. This is problematic given that food security rests on having stable access to sufficient food, rather than...

Data from: First evidence of wasp brood development inside active nests of a termite with the description of a previously unknown potter wasp species

Helder Hugo, Marcel G. Hermes, Bolívar R. Garcete-Barrett & Iain D. Couzin
Potter wasps (Vespidae: Eumeninae) are known to exhibit not only sophisticated preying strategies but also a remarkable ability to manipulate clay during nest building. Due to a mixture of plasticity in building behaviour and flexibility in substrate preferences during nest-building, the group has been reported nesting in a variety of places, including decaying nests abandoned by termite species. Yet, evidence of wasps nesting inside senescent termite mounds is poorly reported and, to date, accounts confirming...
