- Size-dependent task specialization in a cooperative cichlid in response to experimental variation of demand (2011, background): “Breeders benefit from their helpers by an increased survival of offspring and a reduced workload in relation to helper number (Balshine-Earn et al. 1998; Brouwer et al. 2005), which increases fecundity (Taborsky 1984) and affects egg size (Taborsky et al.”
- Social experience in early ontogeny has lasting effects on social skills in cooperatively breeding cichlids (2010, unknown): “Offspring are guarded and protected against predators during the entire early development from the egg stage until the juvenile period (Taborsky 1984; Balshine et al. 2001; Brouwer et al. 2005).”
- The Evolution of Social Behaviour (2021, background): “Safety of subordinates is traded against energetic load- lightning of breeders (Taborsky et al., 2007; Zöttl et al., 2013a) and offspring survival (Brouwer et al., 2005), and this is stabilized by a latent threat of punishment and eviction (Fischer et al., 2014).”
- Mothers adjust egg size to helper number in a cooperatively breeding cichlid (2007, background): “In contrast to larger helpers, small helpers and young are related to the breeder pair with a relatively high probability (Taborsky and Limberger 1981; Dierkes et al. 2005), accruing also indirect benefits by caring for younger siblings or half-sibs (Brouwer et al. 2005).”
- Social recognition : A top down view of cephalopod behaviour (2006, unknown): “The helpers gain indirect fitness benefits by helping parents produce more brothers and sisters (Brouwer et al. 2005).”
- Variation in Individual Investment Strategies among Social Animals (2006, background): “…breeders than small helpers (Dierkes et al. 2005) are suggested to pay to be allowed to stay in the territory by helping (Taborsky 1985; Balshine-Earn et al. 1998; Bergmüller et al. 2005a) and they do not need to increase their amount of help when living in smaller groups (Brouwer et al. 2005).”
- Size differences within a dominance hierarchy influence conflict and help in a cooperatively breeding cichlid (2005, background): “survival (Brouwer et al., 2005).”
- Extended safe havens and between-group dispersal of helpers in a cooperatively breeding cichlid (2005, background): “As we observed that helpers can indeed strategically migrate to other groups, and as dominants may gain fitness by accepting additional helpers (Taborsky, 1984; Brouwer et al., 2005), helpers might trade their helping contribution for being accepted in a territory that provides beneficial conditions”
- Alternative reproductive tactics and life history phenotypes (2010, background): “Both, male and female dominants profit from the presence and effort of subordinates in the group by increased productivity (Taborsky 1984) and offspring survival (Brouwer et al. 2005).”
- Large group size yields group stability in the cooperatively breeding cichlid Neolamprologus pulcher (2005, methodology): “But the majority of experimental studies so far conducted seem to support this general finding (e.g., Brown et al., 1982; Taborsky, 1984; Mumme, 1992; Komdeur, 1994; Brouwer et al., 2005).”
- Life history and behavioral type in the highly social cichlid Neolamprologus pulcher (2010, background): “Benefits can be derived by helping relatives (Brouwer et al. 2005), reproductive participation (Heg2008;Heg andHamilton2008; Heg et al.”
