“…Other antagonistic interactions between protected species can be diffused by human intervention. For example, Gumm et al (2011) describe recent interactions between two endangered fish species; as habitat became more restricted, one began to prey on the eggs of the other, contributing to its decline. By expanding and restoring breeding habitats, managers were able to decrease egg predation rates and populations rebounded (Gumm et al 2011).…”

Finally, where a plant and herbivore interact strongly with sublethal effects for the plant (e.g., Kincaid's lupine and Fender's blue butterfly), habitat improvements included vigorous seeding of host plants (Schultz 2001).…”

“…These challenges may be compounded when multiple rare species share habitat or interact with one another, as actions taken to recover one species may or may not benefit the other species (Simberloff 1998). Antagonistic interactions between rare species can lead to management conflicts; for example, endangered animals may compete for nest sites or foraging areas with each other (Lee et al 2007;Oro et al 2009), or may prey on one another (Gumm et al 2011;Chadés et al 2012). Occasionally, the species interact intimately, necessitating extensive, close coordination among researchers and managers involved in recovery efforts.…”

“…These fishes have been monitored for almost two decades, and significant pupfish population reductions have been apparent, with just one territorial male in 2006 (Gumm et al 2008) down from over 50 territorial males in 1998 (Leiser & Itzkowitz 2003). The initial loss of about half of the pupfish territories is attributed to emergent plants, such as bulrush (Scripus robustus), which eliminated large portions of the pupfish's spawning areas (Gumm et al 2011). The remaining decline appears to be due to egg predation by gambusia (Gumm et al 2008(Gumm et al , 2011, similar to the effects invasive gambusia have on other pupfish (Rogowski & Stockwell 2006).…”

Conservation efforts should consider many aspects of the endangered species' life history and behavioral ecology. Additionally, when multiple endangered species interact, those relationships must also be considered when exploring recovery plans for either or both species. In our continued efforts to conserve the critically endangered Leon Springs pupfish (Cyprinodon bovinus), we explored consistency in aggression toward the endangered sympatric Pecos gambusia (Gambusia nobilis), that attempt to prey upon pupfish eggs during spawnings. We repeatedly observed 13 territorial male pupfish and measured individual aggression, focusing on defensive chases against gambusia and interactions with other pupfish. Short-distance chases at gambusia and chases of territorial neighbors were significantly repeatable, indicating that pupfish show behavioral consistency, or "personality". Moreover, male pupfish that gave more short chases to gambusia experienced higher spawning success. Together, these data suggest that personality can predict reproductive success and thus should be considered by managers working to conserve endangered populations. Conservationists should take into consideration that differential reproductive success may certainly be relevant to the recovery of at-risk species.

Choosing an optimal strategy to sustain imperilled wild populations is challenging, and many methods may be implemented before reaching an effective strategy. A review of previous conservation efforts used to maintain an endangered desert pupfish (Cyprinidon bovinus) are presented here. Conservation strategies for C. bovinus have included removal of fish hybridizing with a non‐native species, reintroduction of captive‐bred C. bovinus into their historic range, and habitat restoration and expansion. In general, these methods have successfully increased the C. bovinus population over a 15‐year period, with habitat expansion appearing to be the most critical intervention method. Habitat restorations that increased the available breeding habitat for C. bovinus and the total number of breeding males were also associated with a downward trend in individual male reproductive behaviour. Since habitat expansion resulted in unexpected consequences for reproductive ecology, it emphasizes the importance not only of monitoring species abundance but also of evaluating individual reproductive behaviour when implementing conservation strategies.
