Abstract Solar power is a renewable energy source with great potential to help meet increasing global demands and reduce our reliance on fossil fuels. However, research scarce how solar facilities affect wildlife. With input from professionals in ecology, conservation, energy, we conducted research‐prioritization process identified key questions needed better understand impacts of We focused animal behavior, which can be used identify population responses before mortality or other fitness...
In animals, signaling behavior is often context-dependent, with variation in the probability of emitting certain signals dependent on fitness advantages. Senders may adjust rate depending receiver identity, presence audiences, or noise masking signal, all which can affect benefits and costs signal production. cooperative breeding meerkat Suricata suricatta, group members emit soft contact calls, termed as "close calls", while foraging order to maintain cohesion. Here, we investigated how...
Abstract When the fitness costs and benefits of sons daughters differ, offspring sex ratio manipulation could be an important reproductive tactic. We explored effects environment maternal caring ability on to test four adaptive modification hypotheses: extrinsic hypothesis (EMH), carrying capacity (CCH), Trivers-Willard (TWH), cost-of-reproduction (CRH). The EMH CCH propose that environmental conditions shape ratios, directly or in interaction with condition. TWH CRH predict a positive...
Males engaging in same-sex competition can assess the strength of an opponent by means behavioural display order to avoid escalated interactions. There is no published record male–male fighting with lethal consequences eastern grey kangaroos, Macropus giganteus. The combat between two males reported here had a fatal outcome.
The efficiency of communication between animals is determined by the perception range signals. With changes in environment, signal transmission a sender and receiver can be influenced both directly, where signal's propagation quality itself affected, indirectly senders or receivers' behaviour impaired, impacting for example distance them. Here we investigated how meerkats (Suricata suricatta) Kalahari Desert adjust to these challenges context maintaining group cohesion through contact calls....
During recent decades, most endangered species have suffered serious population declines. Little has been documented on leopards inWest-Central Africa and as a result the efficiency of protection measures wildlife managing practices can be questioned. Using 416 occurrences leopards, we investigated relationship between different environmental factors leopard distribution to establish baseline this feline. Leopards are mainly present in two large populations: one forest habitat, other savanna...

Abstract The evolution of reproductive strategies is affected by the ability organisms to deal with future environmental conditions. When environments are temporally unpredictable, however, it difficult anticipate optimal offspring phenotype. Diversification phenotypes, a strategy called diversified bet‐hedging, may allow parents maximize their fitness reducing between‐year variation in success. link between diversification phenotypes and individual success, has rarely been documented...
AbstractWhen sons and daughters have different fitness costs benefits, selection may favor deviations from an even offspring sex ratio. Most theories on ratio manipulation focus maternal strategies sex-biased expenditure. Recent studies report paternal influences both postpartum We used long-term data marked kangaroos to investigate whether how mass skeletal size, determinants of male reproductive success, influenced (a) in interaction with (b) When mothers were light, the probability having...
